Need part numbers, if they exist

Audi won't sell these parts to you, they want you to buy a wastegate and a 
new turbo....but...

>1) Wastegate diaphragm for K26 turbo
you can get these from a # of audi parts sources like TAP, BLau, etc.

>2) K26 turbo rebuild kit
you have to order this from either TurboCity in Cali. which is a full kit 
w/ instructions or get from Bramall turbo in Canada, which is an OE 
supplier of the triple-K turbo kits. I would go w/ Bramall, since it's 
cheaper and original parts, but it doesn't come w/ instructions. I do have 
a copy of the instructions if you need it. Rebuilding the turbo is easy, 
but you need to re-balance if you change the compressor wheel or turbine, 
or if you forget to mark they're relative position, before taking it apart. 
If you have a damaged compressor wheel or turbine, yer probably better off 
sending the whole turbo out to have it rebuilt and balanced. Also, not all 
turbos can be fixed by using the kit. The bearings are original size and if 
the turbine shaft or the bearing housing is worn, the bearings will move 
around, causing oil leaks and future damage. Best thing to do is open it up 
and see how bad it is, and use a micrometer on the shaft and bearing 
housing. good luck.
