Mercedes-Benz E-Class MOT failure rates: what fails, what to fix
What the DVSA MOT data shows for the Mercedes-Benz E-Class. The most common failure categories and what each one typically costs to put right.
Mercedes-Benz E-Class models have specific patterns when it comes to MOT failures. Understanding these can help both buyers and sellers make informed decisions.
Common failure categories include brakes, suspension, lighting, and emissions.
Older E-Class models (10+ years) show higher failure rates.
Brake repairs typically cost between £150 and £400.
Suspension issues can range from £200 to £600 to fix.
Lighting failures are generally under £100.
Common Failure Categories
The Mercedes-Benz E-Class often fails MOTs due to issues with brakes, suspension, lighting, and emissions. Brake components, including pads and discs, frequently show wear, especially in models from 2010 onwards. Suspension problems can arise from worn bushings and shock absorbers, particularly in vehicles over 10 years old.
Age-by-Age Failure Rates
MOT failure rates tend to increase with the age of the E-Class. Vehicles less than three years old generally pass without issues. However, as they approach 10 years, failure rates can exceed 30%. This trend continues, with many 15-year-old models failing due to accumulated wear and tear.
Quick Fixes vs Structural Issues
Some MOT failures can be resolved quickly, such as replacing bulbs or brake pads. These repairs are often straightforward and inexpensive. However, structural issues, like significant suspension damage or exhaust system failures, can be costly and time-consuming to fix.
Cost Ranges for Typical Failures
Understanding the costs associated with common failures can aid in budgeting for repairs. Brake repairs typically range from £150 to £400, depending on the extent of the work needed. Suspension repairs can vary widely, costing between £200 and £600. Lighting issues are usually minor, with costs typically under £100.
