Ok ppl. I'm really confused at the moment. My wife has just recently bought a very nice 2002 3.0 d sport X5. All has been great till I had to change the centre fuel pump.
After reconnecting the battery, I have no interior lights other than the ones on the tailgate, the key fob no longer locks/unlocks the doors other than the tailgate and the heater always returns to 22 degrees after turning off the ignition.
It almost sounds like it's not holding on to it's memory. Sorry if I sound a little on the dim side. But this is not a car I'm familiar with. I'm more used to my 300ZX TT and motorbike.
Any help would be more than welcome. Thanks!
