1. Sidelights work ok but switching to main beam switches on the full beam too and I can't use the stalk switch to turn them off. The Blue full beam light remains lit on the dash. I can't flash the lights. So it's side lights or full beam. Nothing in between.
2. ABS, Park Light, Tyre pressure light, traction control light all lit up in orange on the dash. I'm hoping it's all related. I've checked the tyre pressures as i understand it can create havoc if a tyre is badly under-inflated.
3. No response from the key fob. Alarm doesn't activate, doors don't lock/unlock. Fob seems ok. (Relays recently changed on the BCM (GM5) module.
It still drives perfectly (but clearly no ABS) so it's such a shame it's being a pain in the arse!
Please please help before I drive it into a lake!  |
How's the battery? These cars HATE batteries that are on their way out.
If you haven't driven the car a lot the key may need charged or it lost its programming, you can program it easy without tools just look for instructions. Happened to both of my Z4s.
There most likely isn't an alarm to activate unless it's aftermarket...and if it is aftermarket there may lie your whole issue. Alarm systems are know to cause absolute havoc if on their way out.
I have a feeling all is just battery related, I would go that route first and see how it is. Like another poster said, could be rodents as well. Don't give up, these cars are pretty fuss free...the 2.5i is such an easy engine to work on as well.
