 My 2010 Tiguan looks brand new. I loved the car. I've driven it about 97k highway miles. Took it to mechanic after check engine light kept coming on. The car became noisy and ran rough. The mechanic (who I've had for years and has advised me regarding all of my vehicles & never failed me yet) said it might be just plugs or such. He went through my engine & said  it looked like the turbo was blowing out 2 of the cylinders. The check engine light continued to come back on after replacing the plugs and working on whatever else could cause such a problem.  (I don't know much about engines) & he said I should get rid of the vehicle as quickly as possible as a repair to fix the problem would be extremely expensive and not worth it. I looked for a recall notice and saw that many folks are having this same problem. I've actually kept the vehicle rather than trading it in. I was offered $3500 trade in and I don't think the dealership where I purchased my new vehicle even realized it had a problem. They looked at the vehicle and did not road test it. I would hate to see someone else purchase my old car and get stuck with really big problem. I have 2 other vehicles. One with 89k miles and one with close to 200k miles. I take good care of my cars.
