Volkswagen Touareg MOT failure rates: what to expect
What fails on a Volkswagen Touareg at MOT, how often, and what each fix typically costs.

The Volkswagen Touareg often faces specific issues during its MOT tests. Common failures include problems with the suspension, brakes, and emissions systems. Repair costs can vary significantly, but understanding these common faults can help owners prepare for potential expenses.
Suspension Issues
One of the most frequent reasons for MOT failures in the Volkswagen Touareg is suspension problems. The air suspension system, while providing a comfortable ride, can develop faults over time. Common issues include leaks in the air springs or failure of the compressor.
Repairing or replacing air springs can cost between £300 to £600 per corner, while a new compressor may set you back around £400 to £800. Regular maintenance can help mitigate these issues, but owners should be aware of the potential for significant repair bills if problems arise.
Brake System Failures
Brakes are critical for safety, and any issues with the braking system can lead to an MOT failure. The Touareg is known for its robust braking system, but wear and tear can lead to problems with brake pads, discs, or even the brake callipers.
Replacing brake pads typically costs between £100 to £250, depending on the quality of the parts used. If the brake discs also need replacing, this can add another £150 to £300 to the total bill. Regular checks and timely replacements can help keep costs down and ensure safety.
Emissions Control Problems
With increasing scrutiny on emissions, the Touareg’s emissions control system is another area where failures can occur. Common issues include faulty catalytic converters or oxygen sensors, which can lead to increased emissions and a failed MOT.
Replacing a catalytic converter can be quite costly, often ranging from £500 to £1,200, depending on the model year and parts used. Oxygen sensors are less expensive, typically costing between £100 to £200 for parts and labour. Staying on top of emissions system maintenance can prevent costly repairs.
Electrical System Failures
The electrical system in the Volkswagen Touareg can also lead to MOT failures, particularly with issues related to lights, dashboard warnings, or battery performance. Problems with wiring or fuses can cause components to malfunction, leading to a failed test.
Repair costs for electrical issues can vary widely. Simple bulb replacements may only cost £10 to £30, while more complex wiring repairs can escalate to £200 or more. Regular checks of the electrical system can help identify issues before they lead to an MOT failure.
Tyre Condition
Tyres are a crucial part of vehicle safety and are a common reason for MOT failures. The Touareg, being a larger SUV, requires tyres that can handle its weight and performance. Issues such as uneven wear, low tread depth, or damage can all result in a failed test.
Replacing tyres can be a significant expense, with costs ranging from £100 to £300 per tyre, depending on the brand and specifications. Regularly checking tyre pressure and tread depth can help avoid unexpected failures and costs during the MOT.
Exhaust System Issues
The exhaust system is vital for both emissions control and vehicle performance. Common problems in the Touareg include leaks or damage to the exhaust pipes or silencer. Such issues can lead to increased noise levels and emissions, resulting in a failed MOT.
Repairing exhaust issues can vary in cost. Minor repairs may only cost £100 to £200, while more extensive replacements of sections or the entire exhaust system can reach £500 to £1,000. Regular inspections can help catch these problems early and prevent costly repairs.
By being aware of these common issues and their associated costs, Volkswagen Touareg owners can better prepare for their MOT tests and maintain their vehicles effectively.
