2016 Audi TT 2.0L Diesel · KW65 EDK

The vehicle remains currently roadworthy, but the maintenance trend shows a developing issue regarding underbody corrosion. While the most recent test in April 2026 at 32,229 miles identified a minor inoperative offside registration plate lamp, the primary concern is the persistent corrosion on both rear suspension arms. This defect has appeared consistently in 2024, 2025, and 2026, indicating that the oxidation is progressing and has not been addressed. The mileage profile is exceptionally low for a ten-year-old vehicle, averaging approximately 3,200 miles per year. The data shows consistent annual usage between 2022 and 2026, with the car covering roughly 5,000 miles over the last four years. This low mileage suggests that mechanical wear and tear on the drivetrain and engine is likely minimal, but long periods of inactivity often correlate with the type of surface corrosion noted on the suspension, as stationary vehicles can experience accelerated rust and degradation of rubber components due to lack of airflow. A buyer must perform a thorough physical inspection of the rear suspension assembly to determine the depth of the corrosion. Since the tester has flagged the suspension arms for three consecutive years, it is vital to verify if the metal is merely scaling or if structural integrity is being compromised. The inspection should also check the condition of the rubber bushings and brake discs, as low-mileage cars frequently suffer from seized calipers or surface rust on rotors that are not used regularly.
