•Run VIN through NHTSA and Audi recall database to confirm all Takata airbag recalls are completed before handing over any money.
•Cold-start the engine after it has sat overnight and listen carefully for any timing chain rattle in the first 5-10 seconds.
•Check oil level precisely, then drive 1,000 km and recheck, any drop of 0.3L or more indicates active oil consumption problem.
•Connect VCDS or OBD11 and check for camshaft timing deviation codes, oil pressure faults, and any stored engine fault codes.
•Request written proof of oil change intervals, insist on seeing receipts confirming 7,500 km or shorter intervals with VW 502/504 compliant oil.
•Inspect coolant condition and level, look for overheating stains around the expansion tank and hoses, and ask for water pump replacement history.

Timing chain, tensioner, and guide rails
Inspect via VCDS and cold-start listen test. Replace proactively if any rattle present or chain stretch detected.
120,000-160,000 km
Piston rings / oil control rings
Monitor oil consumption closely. If consuming more than 0.5L per 1,000 km, plan for ring replacement or engine rebuild.
80,000-150,000 km
Water pump (plastic impeller)
Replace with upgraded metal impeller unit if not already done. Bundle with timing chain service.
100,000-140,000 km
Variable oil pump / oil pressure solenoid
Test oil pressure at idle and high rpm. Replace pump or solenoid if not switching to high-pressure mode above 3,500 rpm.
