Please help strange electrics problems on my E53
 

Hi guys and Girls, I'm new to the forum just wondering if you could assist with the gremlins in my X5.
I own an E53 3.0d 2005 estoril blue a truely lovely car but.......
Have had a number of issues all at the same time:
Self levelling inact message comes on but car is level
Heated seats not working
Ac not working
Central locking from key opens but doesn't close
One touch driver window not working

All the above seem to happen all at once. Before this started and would go away after a couple of days. However for the last couple of weeks the problem has persisted. Any ideas or pointers?
Much appreciated.

Low battery voltage can cause all sort of mischief. Have you checked the non-running and running voltages to confirm battery and alternator health?

I would start with your ignition switch.had some weird gremlins myself and that fixed it

Thanks guys got her booked in with an independant garage next week will tell them your advice. Thanks again

The General Module (GM3) can cause these gremlins as well.
Check out BMW General Module 5 (GMV, ZKE V). This guy repairs general modules, see if you're having the same symptoms he describes on his website.

:iagree: as first thing to troubleshoot and easiest to accomplish. Welcome!

Thanks guys for all your help will update once fixed.

Hi guys,
Just a quick update took car to a so called Indy. Two weeks later and £800 later still same problems. The money was for other items done but Indy said reprogrammed and should now work OK. Stated showing fault on the DSC which may cause the problems. Going to get the battery and alternator checked to see if it's a voltage issue if not may need to take it to a proper Indy any recommendations in West London area?
On going problems are:
Self levelling inactive message
Ac stops working
Key fob opens but does not lock
One touch window stops working
All happen at the same time and intermittently all come back on over days or weeks.
Is there a way to reset the battery?
Thanks for all your kind assistance any help much appreciated

Get a wiring diagram and see if any of these circuits share a common point such as a ground point. Could be a bad ground.

Self levelling inactive message
Ac stops working could be a bad fan, get it scan and see if you have a fan fault
Key fob opens but does not lock could be a coding problem, you can get it scan and see if it is coded to lock.
One touch window stops working could be a coding problem, you can get it scan and see if it is coded to one touch.
All happen at the same time and intermittently all come back on over days or weeks. look for a common circuit problem such as a common ground point.
