Mine’s been a bit of a headache. I’ve had –
1k miles – wastegate rattle
15k miles – subframe clunk (shims inserted under warranty)
19k miles – leaking passenger side transmission output seal (replaced under warranty)
23k miles – TOB failure (full clutch replacement, had to fight VW/dealer to cover the costs)
24k miles – blower motor failure (awful screeching noises when cold, then seized up – out of warranty)
26k miles – subframe motor mount failure (clicking/metallic knocking under varying throttle inputs, excessive engine movement, wheel hop)
My sig lists the modified ECS insert, but I never installed it. The mount issues popped up after the clutch replacement and I believe is more related to the work done by the dealership. It’s going back in next week for them to check it over.
I hate my car until I drive something else, then I realize it's all worth it.
