I've got a 04 174 kombi just recently the brake pad warning indicator has been coming on, not every time just now and again. But as of yesterday the light has come on and stays on every time i start the van. I have had new discs and pads (genuine items) fitted about a year ago and since then the van has covered 5k so there is plenty of meat left on them and the rear pads are about 2/3rds worn but i have had them out and they are nowhere near the wear indicators i have checked the wiring and the plug appears to be damaged on the front wear indicators but on close inspection it is only the outer casing the connection is good and clean i have had it apart and it looks fine i have also changed the brake light switch today as somebody told me that they can cause this problem but it is still the same. Anybody got any ideas this van is driving me insane!!!!
