I'm pretty sure someone else has posted that their 55 plate had the coils replaced when it was in for servicing under the same 'quiet recall'. Interestingly of all the reports I've ever seen of GTI's catching fire all the cars affected were 55 plates and the coils were to blame.
There was another interesting post about the fire issue that linked the fires to recent engine bay cleaning activities that resulted in the coils getting wet / high resistance / melt / fire.
My 05 plate (04 MY) was in the stealers today for its MOT and they didn't mention anything but maybe thats because they didn't check ...
The coils on the 1.8T's used to fail all the time but VW never replaced them FOC out of warranty or issued any sort of quiet recall like this. Then again on the 1.8T's they didn't catch fire either ... so either VW have come over all charitable or they know there is the potential for serious harm / serious bad publicity ala Toyota with these items. Not that I'm cynical of course
