2014 Audi TT 2.0L Diesel · EE12 ANN

Corrosion on the rear suspension arms represents the primary mechanical concern for this vehicle, as noted in the most recent test on 18 February 2026. While the vehicle has maintained a consistent passing record since 2019, the appearance of corrosion on both the nearside and offside rear suspension arms indicates a developing issue with structural component degradation. This follows several years of advisories regarding missing or loose undertrays and sill covers, which may have contributed to increased exposure of the underbody components to road salt and moisture. The recorded mileage of 56,374 miles over a twelve-year period reflects a low annual usage rate of approximately 4,698 miles. This pattern of light usage can often mean that mechanical components such as suspension bushes, seals, and braking systems have experienced less frictional wear than a higher-mileage equivalent, but it also increases the likelihood of components such as the suspension arms and undertrays being subject to environmental corrosion due to extended periods of inactivity or limited exposure to regular cleansing driving conditions. A prospective buyer should pay close attention to the condition of the rear suspension assembly during a physical inspection. The advisories regarding the nearside and offside rear suspension arms suggest that the oxidation is present but not yet at a stage of serious structural weakness. On a test drive, listen for any rhythmic knocking, clunking, or creaking sounds when traversing uneven surfaces or speed bumps, as these symptoms often indicate that corroded arms or worn bushes are beginning to affect the vehicle's handling and geometry. Furthermore, the recurring advisories concerning undertrays and sill covers should be investigated to determine if they are currently fitted and secure. Missing protective shielding can lead to accelerated corrosion of more critical components like brake pipes, fuel lines, or the subframe. Ensure that the underside of the vehicle is inspected for any signs of significant scale or flaking that was not captured in the recent MOT, and check for any steering pull or uneven tyre wear that might stem from the documented suspension arm issues.
