I don't know anything about VW's or Audis, but I will just leave this here. If you don't have a warranty it may not be relevant.

#2)

I own an Audi TTRS which I had put a mild tune on from a reputable company. One day while leaving work, the car started running really rough. It felt like a coil pack had gone off perhaps and the service adviser at my Audi dealership said to drive it in.

About 30 minutes later, as I arrived at the dealer, my TTRS coughed out its last breath.

Upon inspection, the dealer found that one of the rings broke in the number 5 cylinder and it gouged out the block. Basically destroying a $15k short block. As part of Audi’s policy, however, they sent the computer data over to Germany which quickly showed my car was tuned

Warranty Void....

Well, since there are so few TTRS’s in the USA, we have a pretty active forum. After sending my car to the closest independent shop, I went onto the forum and posted my story. Although I don’t believe it was caused by the tune, the fact that it was tuned made it my fault. I accepted that fault and left my story on the internet as a warning to others.

At some point in the following 2 days, someone at Audi noticed my forum post. They contacted me and said that they appreciated the fact that I didn’t put blame on the dealer, or Audi. In the end, they said they would replace my engine under warranty as long as I purchased a new ECU and promised to never tune an Audi again.

I can say that Audi saved my bacon, and likely my marriage....
