I have a serious problem with my 530D Tourer. When I take off the car starts to move but will not power up smoothly, if I feather the accelerator it will normally take off like a freight train (presumabley due to activating the kickdown). Often though it can take 10 seconds for this to happen. It is starting to get serious as its happening constantly now making the car unsafe to drive.
Garage has now spent £600ish resulting in no 4 injector being replaced, three glow plugs replaced and inlet manifold checking (swirl flaps working normally)
Anyone have any ideas?
