I bought this turbo from an auto recycler off a 2003 Audi A4 with 70,000 miles. When installed, it spooled great and easily developed 15psi (the limit on my tune), but I was getting an exhaust leak sound at 9+ psi. My mechanic suggested it was a leak around the turbo wastegate shaft bearing. So, I ordered a virtually new turbo.
Before installing the newer turbo I compared the play in the turbo shaft and wastegate shaft of both turbos--virtually no difference. As you can see in the pictures, the turbo blades are in good shape and there is no sign of the blades hitting the side of the housing--also no signs of heat stress in the wastegate area.
This turbo wasn't the problem it was a couple hard-to-reach bolts on the exhaust manifold that were loose, coupled with a reused exhaust manifold gasket. So, I'm selling this turbo confident it will do the job for miles to come. If you have any problem with it, I will provide a full refund.
