Build my inspection planFrequently asked questions
Is a used A7 expensive to run?
Yes if you buy without history. Air suspension and chain work dwarf the purchase saving.
What is the single best check?
An overnight parked ride height check plus a stone cold start.
Which engine is safest?
Later 3.0 TDI examples with full Audi history are the most predictable.
What should I look out for regarding the BiTDI exhaust system?
The 3.0 BiTDI models feature an active exhaust sound actuator in the rear silencers to mimic a V8 petrol note. These modules frequently fail due to moisture ingress or wiring faults. Check that the exhaust note noticeably changes when switching the Audi Drive Select system into Dynamic mode.
Do the matrix LED headlights require special attention during appraisal?
Yes, the optional Matrix LED headlight units are prone to internal condensation and individual diode failure, which constitutes an MOT failure. Replacement units are exceptionally expensive. Always inspect the lenses for heavy misting and ensure all daytime running light segments illuminate uniformly without flickering when the ignition is on.
How often does the multitronic gearbox need servicing on front-wheel-drive models?
Early front-wheel-drive C7 models used the CVT multitronic transmission, which demands strict fluid changes every 38,000 miles. Failure to adhere to this schedule leads to premature wear of the forward clutch pack and input shaft. Always verify the service history for this specific interval before retailing the vehicle.
