I've got a 17 GTI with the latest revision turbo. Tuned the car at 3000 miles and had turbo failure 6 days later, less than 200 miles tuned. APR Stage 1 with Intake. Flashed back to stock, cleared codes for over-boost, problem persisted. No boost was building, figured okay might be the wastegate. Had it pulled apart and the wastegate was stuck, figured it would be an easy fix. Its a "non serviceable part" so technically VW says you can't fix them. Called APR just to give them the run down and get their take on the situation. My install shop called me back and said they figured out how to fix it but it was looking like a couple hundred bucks. Before I did anything I figured I'd let the dealer take a look and see what they saw.
Long story short, shaft broke due to over-boost. TD1 Flagged, paid out of pocket for a new turbo and install at the dealer $2700 and some change. Ended up talking to VW and the dealer and the warranty is on a case by case biases. Diagnostics on every trip in, check the flash counter, all that bullshit. So needless to say the cars been back to stock sense I've got it back in October, just broke 7000 miles this week. No issues out of the new turbo but I'm sure this one is out of balance too. Lesson here, balance your shit because VW doesn't care.
I know I'm one of the few 17 year model guys with failures but it can and does still happen. I've held off posting my horror story and lurked the past few months, wanted to see if any one else was having issues but it looks like just a handful of us. Ill get everyone the details and paperwork from the install shop and the dealer if you boys are curious. I don't think it was APR in anyway that caused the failure, I think I was just one of the lucky ones with a factory defect. It might have happened down the road if I was stock. The compressor wheel had some play and the added boost did the rest. Motor is fine and just did the first oil change maybe 700ish miles ago.
Needless to say I want to make power in the car, its just been a horrible experience starting on this platform. I know the chances of lighting striking twice is real low, but with my luck I'm gunna be that guy.
