Understanding Part Repair in Car Mechanic Simulator 2021
Part repairing in Car Mechanic Simulator 2021 is a core mechanic designed to add depth and strategic choice to your gameplay. Instead of always opting for brand-new replacements, you can often restore existing parts to a higher condition, saving money on purchases and increasing the profit margin on your repairs or car sales. This feature is particularly valuable for job completion, as higher condition parts contribute to better customer satisfaction and higher payouts. Crucially, parts must be at 15% condition or above to be eligible for repair. Any part falling below this threshold is considered beyond salvage and must be replaced.
Essential Repair Stations and Their Functions
Your garage is equipped with several specialised stations, each designed for specific types of repairs. Unlocking and utilising these stations effectively is key to a successful repair business.
The Battery Charger
Located conveniently near the Garage Expansion doorway, often close to the tyre balancing corner, the Battery Charger is your go-to for revitalising drained or low-condition batteries. It's a relatively inexpensive initial investment at $550, making it an early game essential. All standard batteries, regardless of their current condition, can be charged here. To use it, simply walk up to the charger and place the battery into the designated slot. It's a straightforward process that ensures you're never left with a dead battery for long.
The Welder
For structural integrity, the Welder is indispensable. Priced at $5,000, this tool is specifically designed for repairing car frames. Unlike other repair stations, there's no minimum condition requirement for frames; all car frames can be welded back to a pristine state. To operate the Welder, you'll need to interact with it, move it to the vehicle lift where the frame is located, and then select the 'use' option. This ensures the foundational element of any vehicle is solid before you proceed with other component replacements.
The Work Bench (Parts) / Repair Table
The Work Bench, often referred to as the Repair Table, is arguably the most versatile repair station in your garage. Found within the Garage Expansion (which costs $10,000 to unlock, followed by the Work Bench itself at $1,500), this station allows for the repair of a vast array of engine, suspension, and drivetrain components. To unlock its full potential, you'll need to invest skill points into the Renovator trait, specifically Renovator 1 through 5. Parts must be at a minimum of 15% condition to be repaired here. The repair process involves a mini-game: go to any Work Bench, select the part you wish to repair, and then time your button press to land on the green section of a meter. Success increases the part's condition, while failure yields no change. This interactive element adds a layer of skill to the repair process.
The Body Repair Station (Body Repair Table)
As your garage expands, so too will your capabilities, and the Body Repair Station is crucial for cosmetic and structural bodywork. Located within the Garage Expansion ($10,000), this station comes at a cost of $2,500. It's designed to repair all body parts, with the notable exceptions of lights and windows. While various appearances exist for these stations, they all perform the same function. Similar to the Work Bench, a minimum part condition of 15% is required. To use it, simply go to the station, choose the body part, and engage in the same timing-based mini-game to land on the green section. This station is essential for restoring vehicles to showroom condition for resale or high-paying jobs.
The Brake Lathe Station
The Brake Lathe Station, another valuable addition found in the Garage Expansion ($10,000) for $1,750, is dedicated specifically to brake components. It can repair both standard Brake Discs and Ventilated Brake Discs. Like most other repair stations, parts must be at a minimum of 15% condition. The operation is straightforward: approach the brake lathe and select the disc you wish to repair. This specialised tool ensures your vehicles' braking systems are always in top shape, a critical aspect for both performance and safety in the virtual world.

Unlocking Your Repair Potential: Skill Upgrades
Your ability to repair parts is directly tied to your character's skill progression, primarily through the 'Renovator' and 'Recycling' traits. Understanding how these skills interact is crucial for maximising your repair efficiency and success rates.
The Renovator Skill Tree
The Renovator skill tree is fundamental for unlocking the ability to repair different categories of parts and improving your chances of an "instant repair." It's important to note that higher Renovator levels do not automatically grant the ability to fix parts from lower categories; you must unlock each level sequentially. The chance of an instant repair stacks across levels, meaning with all Renovator upgrades unlocked, you gain a significant 60% chance for a part to be instantly repaired to full condition without needing the mini-game.
- Renovator 1 (Group I Parts): Unlocks the ability to repair parts from Group I. Increases instant repair chance by 2%.
- Renovator 2 (Group II Parts): Unlocks the ability to repair parts from Group II. Increases instant repair chance by 3%.
- Renovator 3 (Group III Parts): Unlocks the ability to repair parts from Group III. Increases instant repair chance by 5%.
- Renovator 4 (Group IV Parts): Unlocks the ability to repair parts from Group IV, including complex components like ABS Modules, Alternators, Fuel rails, Throttles, and Turbochargers. Increases instant repair chance by 10%.
- Renovator 5 (Group V Parts): Unlocks the ability to repair parts from Group V, notably including all Rims. Increases instant repair chance by 10%.
- Renovator 6 (Body Parts): Unlocks the ability to repair Body Parts. Increases instant repair chance by 15%.
The Recycling Trait
While Renovator dictates what you can repair and the chance of instant repair, the 'Recycling' trait directly influences your general repair success rate when performing the mini-game. This trait becomes available early in your career, significantly impacting the efficiency of your repair operations.
- Recycling Level 1 (Level 5): Unlocks the ability to repair parts with a base success rate of 55%. This is a crucial early unlock for profitability.
- Recycling Level 6 (Level 35): Maxing out this trait boosts your success rate to an impressive 95% for both vehicle parts and body parts. This dramatically reduces wasted time and resources on failed repairs.
Furthermore, an excellent bonus applies: when repairing a part that is at 50% condition or above, you receive an additional 4% increase in your success rate. This means that with maxed Recycling (95%), a part above 50% condition has an astounding 99% success rate, making mid-condition parts almost guaranteed to repair successfully. This strategic advantage encourages you to salvage slightly damaged parts over severely broken ones.
What Parts Can and Cannot Be Repaired?
Knowing which parts are repairable is vital for efficient gameplay, helping you decide what to purchase from junk yards or barns, and what to keep from dismantled vehicles. Remember the golden rule: any part, whether auto or body, cannot be repaired if its condition is below 15%.

- Inventory Management: Keep your inventory organised. Quickly identify repairable parts to process them swiftly, preventing clutter and making part retrieval easier.
By integrating these tips into your gameplay, you'll not only save money but also boost your overall mastery of the game's mechanics, leading to a much more rewarding experience.

Frequently Asked Questions (FAQs)
Q: How do I unlock the repair bench / repair abilities?
A: Unlocking repair abilities involves several steps. Firstly, you need to purchase the Garage Expansion ($10,000) where the Work Bench, Body Repair Station, and Brake Lathe are located. Then, you purchase the specific repair stations themselves (Work Bench $1,500, Body Repair Station $2,500, Brake Lathe $1,750, Battery Charger $550, Welder $5,000). Crucially, you must invest skill points into the 'Renovator' trait, starting from Renovator 1 (which requires player level 4 and the first garage expansion) to unlock the ability to repair different groups of parts. Additionally, the 'Recycling' trait, available from player level 5, significantly impacts your success rate for repairs, making them more viable.
Q: Why does my repair bench say "There are no items to work with"?
A: This message typically appears for a few reasons. The most common is that the parts you have in your inventory are either below the minimum 15% condition threshold required for repair, or they are simply not repairable parts at all (refer to the comprehensive lists above for what can and cannot be fixed). It could also mean you haven't unlocked the necessary 'Renovator' skill level for that specific type of part. Ensure the part is in your inventory, above 15% condition, and that you have the correct Renovator skill level active for its part group.
Q: What is the minimum condition a part needs to be for repair?
A: For most parts repaired at the Work Bench, Body Repair Station, or Brake Lathe, the minimum condition required is 15%. If a part falls below this percentage, it is considered too damaged to be repaired and must be replaced entirely. The only exceptions are Batteries, which can always be charged, and Car Frames, which can always be welded, regardless of their condition.
Q: Does the repair success rate change or improve?
A: Yes, the repair success rate significantly improves with the 'Recycling' trait. Starting at 55% with Recycling Level 1, it can reach 95% at Recycling Level 6. Furthermore, if the part you are attempting to repair is at 50% condition or higher, you receive an additional 4% bonus to your success rate, pushing it up to 99% with maxed Recycling. This makes mid-condition parts very reliable for repair.
Q: Can I repair all car parts in the game?
A: No, not all car parts are repairable. While a large variety of engine, suspension, gearbox, brake, rim, and body parts can be fixed, many smaller, consumable, or highly integrated components cannot. Common non-repairable items include spark plugs, filters (most types), belts, fluids, tyres, most exhaust components (except manifolds), and certain specific engine or suspension parts. Refer to the detailed "What CANNOT be fixed" table in this guide for a comprehensive list.
Q: Are modded car parts different for repairability?
A: Generally, the repairability rules apply to modded car parts as well. However, there can be exceptions. For instance, while headlights and taillights of game-included stock cars are typically not repairable, some modded cars may have repairable versions. Conversely, some modded car parts that appear solid might use the 'glass sections' of the car's model, rendering them non-repairable despite appearances. Always test or consult mod-specific documentation if unsure.
Mastering part repair in Car Mechanic Simulator 2021 is more than just a convenience; it's a fundamental aspect of the game's economic loop and a key to achieving high levels of in-game wealth. By understanding the stations, investing wisely in skills, and making informed decisions about which parts to salvage, you’ll transform your garage into a hub of efficiency and profitability, turning discarded components into valuable assets.
