After four days of pure shit on this car of changing pretty much all the front end suspension components I took it back over for it's retest and it started making a funny noise and serious lack of power.
Anyway long story short etc it's started puffing smoke and making a worse and worse noise and after discovering an ill fitting airbox I thought I'd cracked it.
Airbox replaced,started boosting ok but smoking like a bitch,at least it's trying to boost but clouding the street in smoke.
Fucking joy!!!
Still,it looks easy enough to change!!!

I've seen this http://www.ebay.co.uk/itm/Mercedes-M...#ht_1760wt_990

Which looks ok but I'm always weary of buying off t'internet so if anyone knows of a reputable supplier at reasonable prices that would be great.
