•Connect VCDS or OBDeleven and log camshaft adaptation intake bank 1 phase position to check for timing chain stretch
•Cold-start the engine and listen for any chain rattle in the first 10-20 seconds before oil pressure builds
•Inspect the transmission-side crankshaft seal area and bell housing for any oil leakage or residue
•Check for turbo shaft play by inspecting the intake pipe for oil residue and listening for abnormal whine under load, especially above 120,000 km
•Scan all modules for fault codes, paying particular attention to ABS sensor codes (e.g. 00285) and any boost or ignition faults
•Request full service history and verify oil change intervals are 10,000 km or less with correct VW 504/507 spec oil
•Ask whether the car has been remapped or tuned, since chain and turbo wear accelerate faster on tuned examples not running stock boost

Timing Chain & Tensioner Kit
Inspect cam phaser adaptation values via VCDS at every service; replace chain kit proactively if values are out of tolerance
100,000 km
OEM Turbocharger
Check for shaft play and oil leaks; service history of oil changes is critical to turbo longevity, budget for replacement if approaching 150,000 km with no documentation

Crankshaft Seal (Transmission Side)
Inspect for leaks during any gearbox or clutch service; replace if any seepage detected

Do not choose between the 367hp and 400hp RS3 based on assumed reliability differences, both use the same physical engine, turbo, and internals under DAZA, the extra power is an ECU tune difference rather than a hardware revision. Focus instead on documented oil change history and VCDS chain adaptation values regardless of which output the car has, since maintenance quality matters far more than the factory power figure for long-term reliability.
