The turbo seals on my A3 1.8T went and it started making smoke... So I've pulled the turbo and stripped it for a rebuild, hoping that new seals and bearings would do the job - but the wear on the shaft is a bit too much so it looks like a new CHRA is need. Trouble is, it looks like it's been stripped before and the blue tag is missing (and a few bolts/washers weren't right either). I've read a good few threads/FAQs and I've looked up the part numbers on the housings and they look OK - I think it should be a K03-053 - and the compressor has got eight vanes but I'd like to confirm the part numbers, especially for the CHRA. Can anyone point me to a good reference so I can check? And any recommendations where to buy? Nerings is all over ebay, are they any good? thanks, J.
