Ok this has been annoying the f'in hell out of me for about a week now. Information just wasnt there to be found but I have done it I think.... LINK to it HERE What you are looking for is the Passat TDi 2006 140 and 170bhp 2.0 TDi 140 bhp is using a new turbo from what I know, never seen it before or mentioned, its using -GT1646V Has anyone ever heard a of a GT16 before? The 140 is still using PD also, where as the 170 is using the new piezo injectors, think its PPD for short! 2.0 TDi 170 bhp is using a new turbo also from what I know, never seen it before or mentioned, its using -GTB1749VM From what m0rk mentioned in passing in another thread I taking the M to stand for the manifold and turbo being one "unit"? Anyway I can finally sleep now knowing this. Hope this is correct, if anyone knows anymore info please tell me.
