I got the RED COG yesterday and my M5 is hard down. Had to get it towed and now they can't look at it until Monday. I got my first RED COG at around 32,000 miles and got the Clutch and Flywheel replaced. My M5 is now at 59,000 miles. This time it was different. I fear my SMG pump may be bad. The last time I had a RED COG it took them 2 weeks to repair. But, I am glad that it happened now as my aftermarket warranty is up in May 2011. I'm still hoping that they will cover the repair under my extended warranty. In any case I thinking about selling my beast after they make the repairs. I do believe that my car is a March '06 build, I'm starting to think that maybe 2006 models are plagued.
