A few months ago I took my 330d auto into an independent BMW specialist in Aldershot, not naming names at this point however people on here will know who I am talking about. The issue was lumpy tick over and number 4 injector was the culprit so under my warranty direct warranty this was replaced. The problem of the lumpy tick over started again and infortunately as we had moved out of the area I took my car this time to another forum recommended specialist in Caversham Berkshire only to be told that number 4 injector again was the issue. This time however it was the way in which the previous garage had installed this that had caused the problem, the injector had been forced in at such an angle it us still in the garage as they try and remove it without damaging the head. As well as this they have found other issues with the previous garage quality if work, however my biggest concern is that warranty direct will not contribute to the cost of putting right the Aldershot based mechanics butchery of my car as they say they do not cover faulty workmanship. Please can anybody help with what I can do next I am lumbered with a bill so far of over £1100 and no way of seeing what I can do to recoup it.
