What to check before you buy a 2011 Audi A4

A useful visit to this page takes five minutes. YearTell does not score years and cannot see the vehicle in front of you.

  1. Look up the VIN for open recalls at nhtsa.gov even if this page lists none.
  2. Engine. Have a shop check for oil consumption, coolant leaks, rough idle and unusual engine noise.
  3. Transmission / driveline. Have a shop drive it and check the transmission: hard or delayed shifts, burnt-smelling fluid, and 4WD engagement if equipped.
  4. Automatic braking / collision warning. Ask whether the warning lights stay off and whether related recalls were done.
  5. Skim a few owner reports below for Engine. Look for the same symptom repeating.
  6. Take that list to a mechanic. Do not turn the complaint total into a score.

Engine oil consumption, timing chain. This is a massive problem among Audi vehicles across the board. Engine oil consumption is abnormal and if unnoticed leads to engine dying in the middle of the road which is dangerous and I’ve personally had this happen to me on multiple occasions. The engines timing chain goes bad and causes the entire engine to need to be replaced which consumers have to pay for out of pocket. Damage from timing chain, rough idle, sluggish engine performance, rattling, engine failure. There are large amounts of consumers experiencing the exact same issues. Something needs to be done it’s not safe at all and Audi should be held responsible and liable to fix these issues. The engines are deteriorating at an abnormal and accelerated rate.

So there have already been recalls on some audis for oil consumption. I have a 2011 Audi A4 quattro and it goes through oil like crazy. It's ridiculous I believe it's because of faulty piston rings which led to faulty head gasket witch leads to the spark plugs, and coils.

As of yesterday 10/18/2023, the drivers seat belt would not connect, I forced it to connect, but the dash light indicator remains on. also, difficult to release. I'm concerned that in an accident the air bags won't deploy and worse I may be trapped in the vehicle. My mechanic told me that there were recalls on these Audi's, however I can't find any and the dealer said there is no recall and that they would charge me $200 dollars just to inspect it.

Vehicle has horrible oil consumption due to piston rings being defective upon manufacture. Vehicle will have slew of problems, including stopping in the middle of the street, risking the lives of everyone in the car. Audi Dealer knows of the problem with the model from this year (B8) and they refuse to fix.
