Pre-purchase inspection checklist

2013 Audi S6 Prestige

VIN WAUF2AFC5DN109023

Inspect these first — most-reported on this model

Engine (33 owner reports)Listen for knocks or ticking, check for leaks and blue/white exhaust smoke, and make sure it doesn't overheat. No check-engine light should be on.
Power Train (8 owner reports)Drive through every gear: watch for slipping, hard or delayed shifts, and shudder. Check for transmission/driveline leaks and noises.
Fuel/propulsion System (3 owner reports)Check for fuel or battery warnings, hard starts and stalling. On a hybrid/EV, confirm charging and range behave normally.
Electrical System (3 owner reports)Test every electrical feature: windows, locks, infotainment, charging and all lights. Watch for flickering, dead accessories or warning lights.
Suspension (2 owner reports)Listen for clunks over bumps, check the car sits level, and look for uneven tire wear and worn shocks or struts.
Air Bags (2 owner reports)Confirm the airbag light turns on then off at startup — if it stays lit there's a fault (costly, and a safety risk). Check for signs of prior deployment.
