Volvo XC60 T5: Oil Change & DPF Explained

Maintaining your Volvo is key to its longevity and performance. This guide will walk you through the essential process of changing the motor oil and replacing the oil filter on the popular Volvo XC60 T5, specifically models from 2015 to 2017 equipped with the 2.0-litre turbocharged inline four-cylinder engine (B4204T11). We'll also touch upon a common concern for diesel owners: the Diesel Particulate Filter (DPF) in the Volvo XC70 D5.

Volvo XC60 T5: Engine Oil and Filter Change

Regular oil changes are arguably the most crucial maintenance task for any vehicle, and your Volvo XC60 T5 is no exception. Fresh, clean oil lubricates moving parts, reduces friction, dissipates heat, and helps keep the engine clean. This guide is tailored for DIY enthusiasts looking to tackle this job themselves.

Tools and Materials You'll Need:

Before you begin, ensure you have the following items readily available:

• Torx T30 star bit screwdriver
• 17mm socket with a 3/8" drive ratchet
• 86mm oil filter wrench with 16 flutes
• Automotive funnel
• New synthetic SAE 5W-30 motor oil (approximately 6.2 US quarts / 5.9 litres)
• New oil filter: Volvo part number 31372212 (ensure this is the correct part for your specific model year)
• New oil drain plug gasket: Volvo part number 977751 (recommended to replace with each oil change)
• Used oil catch basin
• Clean rags or paper towels
• Wheel chocks

Step-by-Step Guide:

1. Warm Up the Engine: Start the engine and let it run for a few minutes. This helps to warm the oil, making it flow more easily and suspending any contaminants.
2. Prepare the Vehicle: Park the XC60 on a level surface. Engage the parking brake firmly and place wheel chocks behind the rear wheels for safety.
3. Access the Underside: Using the Torx T30 screwdriver, remove the eight screws securing the under-engine cover (also known as the skid plate or splash guard). Note that on the driver's side, the cover might also be held by a friction clip. Once all screws are removed, carefully set the cover aside.
4. Locate the Oil Pan and Filter: Slide under the vehicle and locate the silver metal oil pan. The oil drain bolt is typically found at the rear edge of the pan, facing towards the back of the SUV. The oil filter housing, a round black plastic cap, is usually situated just in front of the oil pan.
5. Drain the Old Oil: Place your used oil catch basin directly beneath the oil drain bolt. Using the 17mm socket and ratchet, loosen the drain bolt by turning it counterclockwise. Be cautious as the oil may still be hot. Once loosened, carefully spin the bolt out by hand. Allow the old oil to drain completely, which may take several minutes until it's just dripping.
6. Replace the Drain Plug Gasket: Inspect the old oil drain bolt gasket. It's highly recommended to replace this with a new one (Volvo part 977751) to ensure a proper seal. Wipe any debris from the drain port and the bolt itself. Ensure the old gasket isn't stuck to the engine block.
7. Reinstall the Drain Bolt: Screw the drain bolt back in by hand a few turns, ensuring it threads correctly to avoid cross-threading. Then, use the 17mm socket and ratchet to tighten it. Aim for snug plus a quarter turn, or approximately 28 lb-ft (38 Nm) if using a torque wrench. Double-check that it's secure.
8. Remove the Old Oil Filter: Position the oil catch basin under the oil filter housing. If your filter housing has a small drain plug, you can remove it with a 6mm Allen key to drain some of the oil first (optional). Using the 86mm oil filter wrench and ratchet, loosen the oil filter cap by turning it counterclockwise. Carefully remove the cap and the old oil filter cartridge. Allow any residual oil to drain.
9. Prepare and Install the New Filter: Remove the old rubber O-ring from the filter cap. Lubricate the new O-ring with a bit of fresh 5W-30 oil and slide it onto the threads of the filter cap. Insert the new oil filter cartridge into the cap until it clicks into place securely.
10. Reinstall the Filter Cap: Screw the new filter and cap assembly back onto the engine by hand in a clockwise direction. Tighten it approximately 1/4 to 1/3 of a turn past hand-tight. Ensure it's snug.
11. Add New Oil: Locate the oil filler cap on the engine cover and twist it off counterclockwise. Insert the automotive funnel into the oil filler hole.
12. Fill with New Oil: The 2.0L Turbo I4 engine typically requires 6.2 US quarts (5.9 litres) of oil for a change with a filter. Slowly pour in the new synthetic oil. It's advisable to add about 5.5 to 5.8 litres initially and then check the level electronically.
13. Check the Oil Level Electronically: Unlike older vehicles, the 2015-2017 XC60 T5 does not have a traditional dipstick. You'll need to use the electronic oil level sensor. Insert the key fob into its slot, press the Start/Stop button to turn the ignition to Position II (run mode) without starting the engine. Navigate through the driver information system using the controls on the steering wheel until you find the "Oil Level" option, and press "OK" to display it. The system may take some time to provide an accurate reading, especially after an oil change. Driving the vehicle for about 30km or leaving it stationary for two hours is recommended for the most accurate measurement. Top up if necessary, ensuring you do not overfill.
14. Final Checks: Replace the oil filler cap, ensuring it's securely tightened. Start the engine and let it run for a minute, checking for any leaks around the drain plug and oil filter housing. Turn off the engine and re-check the oil level electronically after the recommended waiting period.

Important Considerations:

• Oil Type: Always use the specific grade and specification of oil recommended by Volvo for your XC60 T5. Using the wrong oil can lead to poor performance and potential engine damage.
• Filter Quality: Using a genuine Volvo oil filter or a high-quality aftermarket equivalent is crucial for proper filtration and engine protection.
• Torque Wrench: While not strictly necessary for the drain plug, using a torque wrench ensures you don't overtighten or undertighten it, preventing leaks or stripped threads.

Volvo XC70 D5 and DPF Issues

The Diesel Particulate Filter (DPF) is a component designed to reduce soot emissions from diesel engines. However, for vehicles like the Volvo XC70 2.4 D5, especially those used primarily for short city journeys, DPF problems can be a significant concern.

What is a DPF and Why Does it Block?

A DPF traps harmful soot particles. The engine's computer attempts to periodically burn off this trapped soot through a process called 'regeneration'. This usually happens automatically during longer, higher-speed drives. However, if the vehicle is frequently used for short trips, the DPF may not reach the necessary temperature for regeneration, leading to a buildup of soot. This blockage can cause:

• Warning Messages: Typically, you'll see a "Soot filter full – See manual" message.
• Reduced Performance: If the DPF becomes severely blocked, the engine's ECU may restrict power (Limp Mode) to prevent further damage.
• Engine Issues: In extreme cases, excessive back pressure from a blocked DPF can lead to turbocharger seal leaks, carbon buildup on the EGR valve, and even prevent the engine from starting.

DPF Warning Lights and Symptoms:

It's important to note that not all DPF issues trigger immediate dashboard warnings. Some vehicles may experience a significant loss of power due to a completely blocked DPF without any prior indication. This is due to the engine struggling to breathe against the extreme back pressure.

Typical DPF Solutions:

When facing DPF problems, you generally have a few options:

DPF Removal (Professional Service):

For drivers whose lifestyle doesn't suit the demands of a DPF (i.e., frequent short journeys), a professional DPF removal service can be a more permanent solution. Reputable companies offer a comprehensive service that typically includes:

• Diagnostics: Thoroughly checking the vehicle's systems to confirm the DPF issue and reset fault codes.
• Physical Modification: Instead of replacing the DPF with a straight pipe (which will cause MOT failure), the existing unit is modified internally. This modification is non-visible and ensures compliance with MOT regulations.
• ECU Software Modification: The DPF system is deactivated within the engine's control unit (ECU) via the OBDII port. This is done manually, not with generic software, to ensure all related sensors function correctly and prevent issues like increased emissions or smoke.
• Smoke Correction: Custom software is used to optimise the engine's performance without the DPF, improving fuel economy and preventing smoke.

A professional DPF removal service not only eliminates the recurring costs and headaches associated with DPF problems but can also lead to improved performance and fuel efficiency. Crucially, when done correctly, it ensures the vehicle continues to pass its MOT emissions tests.

Frequently Asked Questions:

Q1: Does my Volvo XC60 T5 have an oil filter?

Yes, the 2.0L turbocharged engine in the Volvo XC60 T5 (2015-2017) is equipped with an oil filter, typically housed in a spin-on or cartridge-style filter housing.

Q2: How often should I change the oil in my Volvo XC60 T5?

Refer to your owner's manual for the recommended service interval. Generally, for synthetic oil, this is typically every 10,000 miles or 12 months, whichever comes first. However, driving conditions can influence this.

Q3: Can I use a different oil grade than SAE 5W-30?

It is strongly recommended to use the oil grade specified by Volvo. Using an incorrect grade can affect lubrication and engine protection.

Q4: What happens if I don't fix a blocked DPF on my Volvo XC70 D5?

Ignoring DPF issues can lead to significantly reduced engine performance, potential damage to other engine components like the turbocharger and EGR valve, and eventually, the vehicle may become undrivable or fail its MOT test.

Q5: Is DPF removal legal?

Removing a DPF from a vehicle that was originally manufactured with one is illegal for road use in many jurisdictions, including the UK. However, professional services offer 'DPF removal' which often refers to the ECU software modification and physical modification of the filter housing to bypass the system while retaining a visually compliant unit for MOT purposes. It's crucial to ensure any work done complies with current regulations.

By understanding and performing regular maintenance like oil changes, and being aware of potential issues like DPF problems, you can keep your Volvo running smoothly and reliably for years to come.
