Not wishing to thread hijack but been doing a bit a of research for my old man who has a 04 Octavia Tdi 1.9 110bhp
(mk4 golf tdi in a czech suit) with similar probs but with billowy blue smoke on start up, loss of power if pushed beyond 3k rpm.
Believe it's engine code BXE(?)
Garage replaced x2 valves to turbo( at 40.00 a toss plus labour) But now are saying that turbo is knackered and would like 1100.00 to replace it with a new one

My old man has asked me if I could dig out some info for him as I may have mentioned something about that for that price surely he could get a bigger turbo/ remap and get a few more ponies out of the old girl

Mk2 Mk3 golfs are more my thing so wondered if any of you lovely people could shed any light or point me in the right direction?
Cheers in advance
NB
