[badbwoy27]

golf is going for a major service on the 10th feb at wolverhampton vw.been told they will be changing the coil packs as there under warranty for free which is a bonus.just wondered if i should also mention to vw not to flash my ecu with any updates because heard that  by doing this, it will wipe my rtech remap off and put me back to stock.
