2004 Porsche 911 3.4L Petrol · S11 AAU

Steering rack instability and suspension wear represent the primary mechanical concerns for this vehicle. While it passed its last test on 28 February 2024, the record shows a persistent issue with play in the steering rack inner joints, which was noted as a specific advisory for both sides in the latest test and previously flagged on the nearside in 2020. This trend, combined with a 2022 failure for worn rear anti-roll bar bushes, indicates a pattern of wear in the chassis and steering linkages that has recurred over several years. The recorded mileage of 157,659 miles over a 22-year period averages approximately 7,166 miles per year, which is consistent with typical usage for a vehicle of this age. This level of accumulation suggests that drivetrain components, suspension bushings, and braking systems have been subjected to standard operational wear. The testing intervals are relatively consistent, confirming the vehicle has remained in active use rather than suffering from the degradation associated with long-term stagnation. A test drive should focus heavily on the precision of the steering. Given the recorded play in the steering rack inner joints, listen for knocking or clicking sounds when turning the wheel at low speeds and feel for any vagueness or a dead spot in the steering center. The previous failure of the rear anti-roll bar bushes suggests a need to monitor for excessive body roll or instability during cornering, as these components are critical for the vehicle's handling characteristics. Attention should also be paid to the exhaust system and braking hardware. The 2020 failure regarding lambda readings indicates a previous issue with the emissions system that requires verification of current operational efficiency. Furthermore, the 2016 record of inner-side corrosion on the rear brake discs suggests a potential for uneven wear or binding calipers. Inspect the inner faces of the discs for pitting and check for any pedal judder or pulling under braking, while also verifying the current condition of the nearside front tyre to ensure the perishing noted in 2024 has been rectified.
