Citroen C4 MOT failure rates: what fails, what to fix
What the DVSA MOT data shows for the Citroen C4. The most common failure categories and what each one typically costs to put right.
The Citroen C4 has been a popular choice among UK drivers. However, its MOT failure rates reveal some common issues that owners should be aware of.
Brakes and suspension are the top failure categories.
Older C4s (8 years+) see a significant rise in failure rates.
Lighting issues are often quick and inexpensive to fix.
Emissions failures can be costly depending on the engine type.

Common MOT Failure Categories
The most frequent reasons for a Citroen C4 to fail its MOT include brakes, suspension, lighting, and emissions. Brake system failures often involve worn pads or discs. Suspension issues can stem from worn shock absorbers or bushings. Lighting failures typically involve blown bulbs or faulty wiring, which are usually easy and cheap to fix.
Age-by-Age Failure Rates
MOT failure rates tend to increase as the Citroen C4 ages. Vehicles around 3-5 years old have a lower failure rate, often below 20%. However, this rate can climb to over 40% for models that are 8 years or older. Owners of older C4s should be prepared for more frequent repairs.
Quick Fixes vs Structural Issues
Many common failures are quick fixes. For example, replacing a bulb can be done in under an hour for a minimal cost. In contrast, structural issues such as corrosion can be serious and expensive to repair. These issues often arise in older models and can lead to hefty bills if not addressed early.
Cost Ranges for Repairs
Repair costs vary widely depending on the issue. Simple fixes like lighting can cost as little as £50. Brake repairs can range from £150 to £400, while suspension work may exceed £500. Emissions repairs can also be costly, particularly if the catalytic converter needs replacing.
