hi mate Ive got a valver for every day driving, i had a misfire problem when engine was hot between 3 4000 revs Changed the usual stuff,coil,leads,plugs. manage to sort it after pulling all my hair out. on mine it turned out to be the ecu feed relay.Ask vw maindealer,the plonker said no such part, so had to tell him to keep his expert knowledge to himself and do his job and look on the computer. it was the best £10 ive spent on my car. if you need part no.. hopefully tomorow. Hope it helps
