Title is kind of misleading.
So the WASTEGATE was actually faulty, not the turbo itself?
On the TSI the wg is rivited on to the turbo so it cant be replaced.
If VW hadnt of done this then they could hav ejust swapped in a new wg
Not really, riveted or not almost no manufacture would have the dealer just replace the wastegate if it failed on an internally gated application. They were never riveted on any of the previous vw/audi turbo applications and there was never just a wastegate available.
Wastegates constantly failed on the 97/98 A4s and passats and Vw/Audi put turbos on every car never just a wastegate, those are bolted on.
^^so in turn, its a turbo failure, not exactly the turbo itself as far as the ability to build boost and what not, but the ability to manage itself accordingly. makes sense, thats still part of the turbo and part of its job.
