Startin g from cheapist to most exorbident, they are: 1. Rebuild kit:
seals bearing, gaskets about
$150.2. A new center section all the stuff plus both wheels ¢er plate
all assembled and balanced. Thats the way I had one of my turbos (volvo)
done Price was
around $350-two years ago.Doing it this way depends on the casings being
free of damage.3. Replace the complete turbo. Prices 5-900$ depending on
I've heard positive feedback about Turbonetics, but have not had direct
with them. 4.The Audi dealer, with your Audi on a flatbed. Check with
proctology before opting for this one.I'd Guess $1700 or more. Good idea to
replace oil feed line and be sure drain line is clear. A dirt free work
environment is de rigour
and probably good enough reason for most of us not to risk the potential
mistakes. btdt . Good luck, whatever your choice. Mike
