MOT Mileage Missing? Your Guide to Fixing It

Finding a discrepancy or even a complete absence of a mileage record on your vehicle's MOT certificate can be a baffling and concerning discovery. Especially when your car's history, like your 2009 Peugeot 308CC, points to genuine low mileage, yet a single anomalous MOT entry, or a sudden change due to a metric-to-imperial odometer switch, throws everything into question. You've stumbled upon a surprisingly common, yet often unaddressed, issue that can have significant implications for your car's value and future sale. This comprehensive guide will delve into why these discrepancies occur, what impact they can have, and crucially, what practical steps you can take to rectify the situation and ensure the integrity of your vehicle's history.

Understanding the nuances of how mileage is recorded and interpreted is paramount, particularly when dealing with cars that might have seen service in different measurement units. The journey of your Peugeot, from potentially running its life in kilometres to suddenly showing miles, highlights a unique challenge. While it might seem like a beneficial outcome – a lower mileage figure in miles – the inconsistency on official records can trigger red flags for future buyers, insurers, and vehicle history checks. This article aims to equip you with the knowledge and actionable advice needed to navigate this complex terrain, ensuring your car's true story is accurately reflected.

Understanding MOT Mileage Records

The MOT test, a cornerstone of vehicle safety and roadworthiness in the UK, serves multiple purposes beyond merely checking a car's mechanical health. One critical aspect of the test is the recording of the vehicle's odometer reading. This seemingly simple data point is vital for several reasons. Firstly, it helps to track the vehicle's usage over time, providing a chronological history of its mileage. This history is publicly accessible via the Government's 'Check MOT history' service, allowing potential buyers and owners to verify a car's declared mileage against its official records.

The continuity of these readings is crucial. A consistent upward trend in mileage offers reassurance about a car's legitimate history. Conversely, any significant dips or unrecorded entries immediately raise suspicions of 'clocking' – the illegal practice of tampering with an odometer to show a lower mileage. Even if unintentional, as in your case, such discrepancies can lead to serious questions about the vehicle's provenance and value. The MOT tester is legally required to record the mileage displayed on the odometer at the time of the test. While they are trained to identify obvious signs of tampering, the responsibility for the accuracy of the displayed reading ultimately rests with the vehicle owner.

It's also worth noting that the mileage recorded on an MOT certificate is not just a number; it forms part of a vehicle's official record that can be accessed by various entities, including insurance companies, finance providers, and vehicle history check services like HPI. Any inconsistencies here can complicate future transactions, from getting competitive insurance quotes to selling the car without suspicion. Therefore, understanding the significance of this record is the first step towards addressing any issues.

The Kilometre-to-Mile Conversion Conundrum

Your specific situation, where your Peugeot 308CC's odometer switched from kilometres to miles, presents a unique challenge that many standard mileage discrepancy guides fail to address. Modern vehicles, especially those from continental manufacturers, often have the capability to display mileage in both metric (kilometres) and imperial (miles) units. This setting is typically configurable within the car's onboard computer system. While convenient for international travel or personal preference, it can lead to confusion and discrepancies on official records if not managed carefully.

When an odometer is switched from kilometres to miles, the numerical display changes to reflect the equivalent distance in the new unit. For example, 100,000 km becomes approximately 62,137 miles. If a vehicle has spent years recording mileage in kilometres, and then at some point, the setting is changed to miles, all subsequent readings will naturally be much lower numerically. The critical issue arises when an MOT tester records the *displayed* number without acknowledging or noting the unit change. Your observation that a Peugeot main dealer recorded 'miles' on one MOT certificate but 'KM' on a service invoice on the same day perfectly illustrates this bizarre inconsistency, suggesting a lack of awareness or a standard protocol for handling such unit conversions.

The problem is compounded because the DVSA's MOT system primarily expects mileage in miles for UK vehicles. While some testers might be savvy enough to record the unit (KM vs. Miles) if clearly displayed, it's not a universal practice, and an unrecorded unit can lead to misinterpretations. This scenario isn't 'clocking' in the traditional sense, as no fraudulent intent is involved; rather, it's an honest mechanical or user-initiated change that has inadvertently created a seemingly suspicious history. However, to a future buyer or a vehicle history check service, it simply appears as a massive, unexplained drop in mileage, triggering an immediate red flag for potential fraud.

Example of a Unit Switch Scenario:

Consider a vehicle's mileage progression:

• Year 1: 20,000 km (recorded as 20,000 on MOT if tester assumes miles, or correctly noted as KM)
• Year 2: 40,000 km (recorded as 40,000 on MOT)
• Year 3 (Unit Switch): Odometer switched from KM to Miles. Current reading 60,000 km becomes approx. 37,282 miles. MOT tester records 37,282.
• Year 4: Vehicle continues in miles. Reading 45,000 miles.

On the MOT history, it would appear as: 20,000 -> 40,000 -> 37,282 -> 45,000. This drop from 40,000 to 37,282 is the red flag, even though the car travelled more distance.

Why an Unrecorded or Discrepant MOT Mileage Matters

An unrecorded or discrepant mileage on an MOT certificate, particularly one caused by a metric-to-imperial switch, can have several significant and undesirable consequences for you as the vehicle owner. It's not just a minor administrative oversight; it can genuinely impact your car's future.

• Vehicle History Checks (HPI/NMR): This is perhaps the most immediate and impactful consequence. Services like HPI (Hire Purchase Information) and the National Mileage Register (NMR) aggregate data from various sources, including the DVSA's MOT records, insurance companies, and finance providers. If your car's MOT history shows a mileage discrepancy – a drop in recorded mileage, even if legitimate due to a unit conversion – it will likely trigger a 'mileage discrepancy' or 'mileage anomaly' alert on any history check. This flag can be extremely difficult to explain away without robust evidence, casting a shadow of doubt over the car's integrity.
• Resale Value and Difficulty Selling: A flagged mileage discrepancy on a history check can severely impact your car's resale value. Potential buyers, often relying heavily on these checks for peace of mind, will be immediately put off. Even with a thorough explanation, many will opt for a vehicle with a cleaner history to avoid potential headaches down the line. It can make selling the car privately incredibly difficult, and even dealerships might be reluctant to take it in part-exchange or will offer a significantly reduced price.
• Insurance Implications: While less common, a mileage discrepancy could, in theory, affect your insurance. Insurers rely on accurate vehicle data to assess risk. If there's a significant inconsistency in recorded mileage, it could lead to questions about the vehicle's true age, usage, or even potentially invalidate a claim if the insurer deems the information provided was misleading, even if unintentionally so.
• Future MOTs and Servicing: While the immediate impact on future MOTs might be minimal (the tester will simply record what's on the clock), the underlying issue of the discrepancy remains. Each subsequent MOT will add to a history that contains this anomaly, perpetuating the problem. Similarly, service records might continue to be inconsistent if not meticulously managed.
• Peace of Mind: Beyond the practical implications, simply knowing there's a cloud over your car's history can be unsettling. You want to be confident that your vehicle's records accurately reflect its journey and that you won't face accusations of dishonesty when it comes time to sell.

The key takeaway here is that while your situation is likely an honest administrative error, the systems designed to prevent fraud treat all anomalies with suspicion. Proactive steps are essential to rectify this and protect your investment.

Gathering Your Evidence

The cornerstone of resolving any mileage discrepancy is a comprehensive collection of irrefutable evidence. The more documentation you can provide, the stronger your case will be when approaching official bodies or potential buyers. Think of it as building a robust narrative that explains the anomaly clearly and convincingly. Here's what you should meticulously gather:

• All Previous MOT Certificates: Crucially, obtain every single MOT certificate from the vehicle's history. These are vital for showing the progression of mileage, pinpointing the exact test where the discrepancy occurred, and potentially identifying if a unit (KM/Miles) was ever explicitly noted.
• Full Service History (FSH): This is often your most powerful piece of evidence. Service invoices and entries in the service book frequently record mileage at the time of service. Look for consistency in these records, especially around the date of the anomalous MOT. Your observation about the Peugeot main dealer recording 'KM' on the service invoice and book on the same day they recorded 'miles' on the MOT is a goldmine of evidence. This directly supports the unit conversion theory.
• Purchase Invoice/Receipt: Your purchase documentation should clearly state the mileage at the time of sale. This confirms the mileage you bought the car at.
• Previous Owner's Statement: If possible and appropriate, a signed statement from the previous owner (especially if they were the only owner, as in your case) explaining their knowledge of the car's history, the unit settings, or any changes, would be incredibly valuable. Their testimony about the car living its life in metric units reinforces your argument.
• Photographic Evidence: If your car's dashboard clearly displays 'KM' or 'MILES' next to the odometer reading (or allows toggling between them), take clear photographs of this. This can demonstrate the car's capability to switch units.
• Vehicle Manual: The car's owner's manual might detail how to switch between metric and imperial units, further supporting the plausibility of the change.
• Any Communications with Garages/Dealers: Keep records of any correspondence or notes from garages regarding mileage, particularly if they serviced the car around the time of the discrepancy.

Organise these documents chronologically and highlight the key entries that support your case. This meticulous approach will demonstrate your due diligence and commitment to transparency.

Steps to Rectify the Situation

Once you've meticulously gathered all your evidence, it's time to take proactive steps to address the mileage discrepancy. This process often involves engaging with official bodies and potentially the original MOT test station. Remember, your goal is to add an explanatory note to the vehicle's records, not necessarily to change past MOT entries, which is often difficult or impossible unless it was a clear data entry error by the tester.

• Contact the DVSA (Driver and Vehicle Standards Agency): The DVSA is responsible for the MOT scheme. While they typically don't amend historical MOT mileage records unless there's clear evidence of a data entry error (e.g., a '0' was accidentally added or missed), they are the ultimate authority. You can write to them, explaining the situation clearly and concisely, attaching all your supporting evidence. Emphasise the unit conversion aspect. While they may not alter the digital record, they might be able to add an explanatory note to their internal system, which could be referenced if future queries arise. Be prepared for this to be a bureaucratic process that may take time.
• Contact HPI/National Mileage Register (NMR): This is a crucial step, as you rightly identified. HPI, which manages the NMR, is the primary source for vehicle history checks. They have a process for addressing mileage discrepancies. You will need to submit your evidence to them. Their team will review your documentation and, if satisfied with the explanation, they can add an explanatory note to the vehicle's record on the NMR. This note will then appear on any future HPI checks, explaining the reason for the discrepancy and preventing it from being flagged as potential fraud. This is the most effective way to protect your car's future salability. Look for their 'mileage investigation' or 'data correction' process on their website.
• Contact the Original MOT Test Station: While less impactful for official records, contacting the garage that performed the MOT with the anomalous reading can be helpful. They may have their own records that corroborate your story, or they might be able to provide a statement acknowledging the potential for a unit misinterpretation at the time. This might not directly change the DVSA record but can add another layer of supporting evidence for HPI.
• Maintain Meticulous Records Going Forward: Ensure all future MOTs and services clearly record the mileage in miles. If your car displays units, ensure it's set to miles for any official readings. Politely point out the unit to the MOT tester if there's any ambiguity. Keep copies of everything!

The emphasis throughout this process should be on transparency and providing overwhelming evidence. Be patient, as these processes can take time, but the effort is worthwhile to safeguard your vehicle's value and your peace of mind.

Communicating with Potential Buyers

Even after taking all the necessary steps to rectify the official records, you may still encounter questions from potential buyers regarding the mileage history. Transparency is key here. Rather than hoping they won't notice, proactively address the issue with honesty and confidence.

• Prepare a Detailed Explanation: Write a clear, concise explanation of the situation. Describe how the car's odometer switched from kilometres to miles, providing the approximate date or MOT period when this occurred. Explain that this is why the numerical value appears lower on certain records.
• Present Your Evidence: Have all your meticulously gathered documents ready to show. This includes the full service history, all MOT certificates (highlighting the discrepancy and subsequent consistent readings), the purchase invoice, and any correspondence from HPI or the DVSA confirming an explanatory note has been added. Showing the buyer the HPI check with the explanatory note is incredibly powerful.
• Emphasise the Authenticity: Reassure the buyer that this is not a case of 'clocking' but an honest administrative anomaly due to the car's configurable odometer. Emphasise the overwhelming evidence of genuine low mileage, such as the comprehensive service history from new.
• Offer to Share Contact Details (with permission): If the previous owner provided a statement, offer to share their contact details (with their explicit permission) so the buyer can verify the story directly.
• Be Patient and Reassuring: Some buyers may still be hesitant. Be patient, answer all their questions thoroughly, and reiterate your commitment to full transparency. A buyer who feels fully informed and sees the robust evidence is far more likely to proceed.

By being open and providing a wealth of supporting documentation, you transform a potential deal-breaker into a testament to your honesty and the car's genuine low mileage. This approach builds trust and helps the buyer understand the unique circumstances of your vehicle's history.

Preventing Future Issues

Once you've navigated the complexities of resolving a past mileage discrepancy, your focus should shift to preventing similar issues from arising in the future. Proactive measures can ensure your car's mileage history remains accurate and undisputed moving forward.

• Set Odometer to Miles and Keep It There: If your car has the option to display mileage in both kilometres and miles, ensure it is permanently set to miles for all UK driving. Double-check this setting periodically, especially after any battery disconnections or software updates that might reset vehicle preferences.
• Inform MOT Testers and Garages: Before every MOT test and major service, verbally inform the tester or garage about the previous mileage anomaly related to the KM-to-miles conversion. Politely ask them to confirm they are recording the mileage in miles and to make a note if their system allows for unit specification. While they should record what's displayed, a friendly reminder can prevent oversight.
• Review MOT Certificates Immediately: As soon as you receive your MOT certificate, thoroughly review it. Check not only the passes and advisories but also the recorded mileage. If you spot any error or inconsistency, raise it with the test centre immediately before leaving. It's much easier to correct a data entry error on the spot than weeks or months later.
• Maintain Comprehensive Service Records: Continue to keep all service invoices and repair receipts. These documents are excellent corroborating evidence for mileage and show a history of proper maintenance, which adds to a car's value and credibility. Ensure that mileage is clearly stated on all service records.
• Regularly Check Your Online MOT History: Periodically use the government's free online service to check your car's MOT history (gov.uk/check-mot-history). This allows you to monitor the recorded mileage and ensure there are no new unexpected anomalies. It also allows you to see if the explanatory note you requested from HPI or the DVSA is visible or recorded internally.
• Keep a Personal Mileage Log: For ultimate accuracy, consider keeping a simple personal logbook where you record the date, mileage, and purpose of significant journeys or at regular intervals (e.g., monthly). This provides an additional layer of personal evidence that aligns with official records.

By adopting these practices, you establish a robust and transparent record of your vehicle's mileage, ensuring that its true history is consistently and accurately represented across all official and private documentation. This proactive approach will provide you with peace of mind and protect your investment for years to come.

Frequently Asked Questions

Q: What is an MOT mileage record?

An MOT mileage record is the odometer reading noted by the MOT tester at the time of your vehicle's annual MOT test. This reading is then uploaded to the Driver and Vehicle Standards Agency (DVSA) database, forming part of your car's official digital history. It serves as a crucial indicator of the vehicle's usage over time and helps to identify potential mileage discrepancies or 'clocking'.

Q: Can I get an MOT mileage corrected if it's wrong?

Correcting an MOT mileage record is challenging but not impossible. The DVSA will generally only amend a record if there is clear evidence of a data entry error by the test station (e.g., a number was transposed, or an extra digit was accidentally added). For more complex issues like a kilometre-to-mile conversion, you'll need substantial supporting evidence (service history, previous MOTs, etc.) to explain the anomaly. While the original digital record might not be altered, you can often get an explanatory note added to your vehicle's history by services like HPI, which is vital for future sales.

Q: Will a mileage discrepancy affect my car's value?

Yes, a mileage discrepancy, even if legitimate and well-explained, can significantly affect your car's resale value and make it harder to sell. Vehicle history check services (like HPI) will flag any inconsistencies, which immediately raises suspicions for potential buyers. While a thorough explanation and supporting evidence can mitigate the impact, many buyers prefer vehicles with a completely clean and unambiguous mileage history. Proactive resolution is key to minimising this impact.

Q: How can I check my car's MOT history?

You can check your car's full MOT history online for free using the UK government's official service. Simply visit the 'Check MOT history' page on GOV.UK (search for 'check MOT history' on Google), enter your vehicle's registration number, and you'll be able to see all recorded MOT tests, their dates, outcomes, and the mileage recorded at each test.

Q: What if my car was imported and had its mileage in KM?

If your car was originally imported and its odometer displayed kilometres, this is a common scenario for mileage discrepancies. When imported, the mileage at the point of import should ideally be converted to miles and recorded as such. However, if the odometer was later switched, or if early UK MOTs recorded KM readings without conversion, it can lead to issues. The process for resolving this is similar: gather all import documentation, previous service history (especially from the country of origin if available), and evidence of the unit conversion, then approach HPI/NMR with your comprehensive evidence to add an explanatory note to the vehicle's record. This ensures due diligence is shown.
