Audi A4 VIN Number Location
Where to find the VIN on a A4
Locate the A4's VIN on the plate at the base of the driver's side windshield. Audi adds secondary identifiers in the engine bay near the strut tower, inside the trunk lid, and on the door jamb sticker. On B9 generation A4s (2017+), a spare tire well label is also present. Salvage-rebuilt A4s imported from Canada account for a notable share of used inventory in border states, the VIN will confirm original market designation.
The VIN also appears on the vehicle registration, insurance documents, and title. All locations should match. A mismatch between VIN plates is a potential indicator of a rebuilt or salvage vehicle.

The 2009 draws the most complaints. NHTSA owners of the 2009 mention air bag problems, heavy oil consumption and timing chain failures, and more than half of owners of the 2013 describe electric power steering that suddenly stops assisting, sometimes after driving through puddles. CarComplaints lists excessive oil consumption for 2009 through 2014, timing chain tensioner failures for 2009 and 2012, a bad piston for 2012, and stiff steering at highway speed for 2014.

What to check before buying
Run the VIN through the NHTSA recall lookup, including the air bag module, seat sensor and coolant pump recalls. Ask for timing chain, oil consumption and power steering repair records. Look for coolant around the thermostat and water pump. On the drive, check that the steering assist stays on, back up to test the camera and watch the MMI screen for reboots.
