Just picked up the car after the replacement springs went on, and RSTTs, but now I'm hearing a fluttery, ticking sort of noise as the turbo kicks in (sounds like a bearing, or maybe a gasket leak... hard to tell). Looking through threads, I'm thinking downpipe though. I've only driven it once since it had the exhaust manifold replaced, too. Do Audi do "approved" checks on cars they're not selling? I want to just find someone who can make a list of everything that's about to go/needs replaced so I can figure a price and just get everything sorted in one go.
