without any respect to your dealer he is talking out of his exhaust pipe, my GTI has been serviced by that well known indie - ME - for the last two years, when it went in for the cambelt and water pump change (they did me the best price in the local area and its a BIG job) they highlighted to me that there was a recall on the coil packs, mine was running fine, but they said that they would replace them FOC, and mine is an import (RHD) from sweden, I did register it on the vag Uk system when it came in though, for just this type of eventuality, not sure where you are but I would try a few other dealer, worth it if you get for free, oh and mine is an 05 build car, on a 55 plate. Oh and its done 105k miles, if relevant. Good luck, sounds like you need to use a new dealer, luckily we have three different ones within 20 miles of where I live!
