The 2.0 TDI biturbo had ring problems. Its predecessor, the 2.5 TDI, had problems with liner coating: My neighbour worked a lot on them and has seen the surface come off the liner when dropping the oil pan. That was the end of the road for an engine.haha! Yeah our german colleagues handle the EU business, I don't have access to those programs. Thats a ring problem, not a piston one though. And a problem specifically designed and dictated to us by VAG
"Fuel saving" 0w/30 oils also contributed to a lot of camshaft wear, not just on the Transporter 4: My Volvo used a liter of oil per 5000km when i bought it, switching over to the 5w/40 oil as prescribed to the pre 2006 Euro 3 engines, reduced it to 1 liter per 20.000km, though it is still more than my previous S70 with the VW 2.5 TDI (from the Transporter 3) with 565.000km under its belt...
After purchase i learnt that the cam wear was prominent in MY 06, and that better cam hardening solved that from MY 07 onwards... to my luck.
So please dont feel offended when i dont take your word for it, that some coating will solve cylinder wear, just like that... IMHO they are just band-aids invented to solve problems resulting from the choice of ever thinner engine oils...
Yeah, several aluminium casting companies in Holland are closing their doors due to the natural gas prices. Steel doubled last year, availability of regular construction steel is not a problem (yet) though getting Cat OEM components is...And now we all have problems keeping our manufacturing plants fully staffed and operating. Raw material pricing is brutal now too. Tough times.
