After months of trouble, bad starting, juddery idle, juddering under load, and no fault codes!!!! my car has finally decided to put on its engine management light on and speak to me. Basically its a faulty injector on cylinder 2. Whats the likelihood of it being the loom, and if not, wheres the best place to get an injector without getting my leg lifted!!. btw, its a 2004 2.0TDi DSG S-line. Any guidance much appreciated!!!
