Hey Clifton,
So i phoned every Goldwagen and most BM dealers an no one had,
I finally found one at BMW Bryanston JSN and ya lets just say im R1055 poorer this month

found some docs on the web and it literally took me 5 min to replace thanks for your help bud much appreciated,
There was one other thing though yesterday before i replaced the belt i went up to the shop and my car had no boost i was stressed to the max i then got pissed off and just kept my foot flat and then at about 4000rpm it started boosting i switched car off and on again and then it was normal do you have any idea what the hell happened?
