On my way to work early yesterday, filled up the car and was doing about 30ish when the engined starts to cough and splutter. From reading posts on here I'm hoping its just a coil pack so I've got a new one from my local dealer. My question now is, can I fit it without having to clear any fault codes with VCDS? Secondly, is there any easy way to tell which one needs changing without VCDS. Help will be greatly appreciated.
