I had a chat about my problem with my VW dealer today - Specifically the guy who is now on the Service desk but who still occasionally doubles as Mechanic and is now a Revo agent. In other words he's someone whose opinions I trust and someone who can 'take off his VW hat' and be unbiassed with me.
On the basis of everything I was able to tell him, he reckons it's probably the wastegate at fault, which of course is an integral part of the turbo.
After asking why I didn't consider a K04 but understanding my reasoning, he also said that a K03 turbo wouldn't be run in until about 8,000 miles [cue for TT to spit and splutter his disagreement] so the option I was taking was a good one, also taking into account hire car costs.
I'll keep this thread informed, neg, but I am out Friday night and with the Biali boys at APS all Saturday (I'm hoping!), so it may be well after the turbo investigation on Friday.
