I just bought a 1998 a4 b5 that had a k04 on it, the guy who i bought it from only drove it 50miles before the clutch went out and sold it to me, and i cannot see what the turbo says on it but i got the serial number off of it and tried looking it up and came up with nothing so here is the serial number
17050184
the part number is
k04 - T
If anyone knows what brand k04 this is please let me know
Thanks - geof
