Over 1200 responded to their survey, of which 77% have had the fix installed (924). 85% (785) subsequently had problems. Good grief.

...saw it last week.

Mentioned the EGR issue.....and VW denying all. If you're still in two minds about not doing it, this may help you make a decision.

Can confirm 54-55mpg is what I get most of the time (car computer)

...had this exact problem maybe 2-3 times in 2 years. Haven't had the emmissions de-tune. Too intermittent to bother me, but if others have seen it perhaps a 'feature' of the ECU ;)?

Indeed - VW just got caught.

Thanks folks - as I thought.

Indeed....and there is another thread that points out that the engine will have been long-term tested with the ECU as it is, so the long-term effects of this change with respect to reliability/wear are unknown.

Folks,

I'm thinking of getting my nearly 2 year old diesel B7 serviced at a local garage (who I trust) rather than at a VW dealer. I've used them before for warranty services on other cars, so I know they will use VW parts/fluids.

Any advice on VW-specific pitfalls before I do that?

I don't plan to let them apply this "fix". I do not believe them when they say there will be no loss of power or increase in consumpion.
