I have a 2017, T6.1 with the 204ps BiTDi engine and this has had an EGR cooler failure! This was at around 30k miles. Emulsion in the oil filler was evident so took it to VW dealer who changed the EGR valve and told me it would be OK now. What I didn't realise at the time (but certainly do now) was that irrepairable damage had already been done to the engine as a result of the failure. Not long after this the oil consumption was noticeably getting worse and this affected the DPF and SCR such that the engine warning light illuminated. System flushes by the dealer only resulted in a short term "fix" because after about 60 miles the engine warning light (orange) illuminated again.
Dealer wanted ca. £15k to replace the engine and VW customer service UK refused to discuss the problem.
I am now looking at stripping and re-building the engine but am concerned that it may require more than a re-bore and new pistons and rings. If other major comp
onents are also damaged, e.g. turbos then the total rebuild cost at retail prices could end up approaching the VW quote.
Does anyone have any experience of doing a rebuild after this type of damage and how extensive was the damage?
Does anyone know a reputable organisation that does rebuilds or exchange engines?
