4.5L V8 Twin-Turbo - Turbo
Petrol
While driving at low speeds, gently apply the brakes to check for any 'clunking' noises from the front suspension, as control arm bushings often show signs of wear in these heavier 955 chassis.
Park the vehicle on a flat surface and leave it running for 5 minutes; check beneath the engine bay for any signs of coolant pooling, as the plastic coolant pipes in the 'V' of the engine are notorious for brittleness.
Accelerate firmly in a safe area to check for any hesitation or surging, as the ignition coils and spark plugs are critical performance components that may be nearing the end of their service interval.
Operate the air suspension (if equipped) through all height levels while stationary; ensure the pump engages smoothly and the car levels out without excessive delay or dashboard warning lights.
Usually marks the point where original secondary water pumps and plastic cooling components require a thorough inspection.
Common timeframe for refreshing the ignition system including coils and ensuring the transmission fluid has been serviced.
Recommended interval for assessing the condition of the driveshaft center support bearing and checking for any driveline play.
Ensure the logbook shows a history of oil changes at least every 10,000km using high-quality synthetic lubricants.
Verify that the cardan shaft center support bearing has been inspected, as it is a common wear point on these all-wheel-drive models.
Confirm the air suspension compressor is running quietly and not struggling to maintain the set ride height.
Check for signs of moisture under the carpets, as clogged sunroof drains are a common quirk that can affect cabin electronics.
Keep a close eye on the engine temperature gauge during your test drive to ensure the thermostat is functioning within the optimal range.
Estimated repair costs if issues arise
Future Budget Planning: Many 955s had their plastic pipes replaced with aluminum versions. If this hasn't been done, it is a significant job that involves removing the intake manifold, but it provides great peace of mind.
Future Budget Planning: Depending on the car's history, you might eventually need to budget for a compressor refresh if the vehicle takes longer to raise or displays levelling faults on the dash.
Future Budget Planning: If you notice a vibration under acceleration, the rubber support for the driveshaft may be perishing. It is a common maintenance item that ensures smooth power delivery.
Future Budget Planning: Given the weight of the V8 Turbo engine, front-end components work hard. Budgeting for a refresh of the control arms and bushings will significantly sharpen the handling if the car feels a bit 'loose'.
