For some reason I have no power to both front seats, no steering wheel tilt, no heated seats, and a stability control malfunction warning on the Idrive along with dash lights having to abs etc. I checked ALL fueses throughout the car and all are ok.

Is there a module or relay that could be causeing this issue? Almost has to be something simple.

Car is a 2004 545i sport with 80k

 

Could it be the battery is going?

 

Brand new battery holding almost 13v.

This is the second battery in a month.... Dunno whats up with that! Alt?

 

I know this black relay in the trunk gets hotter then heck. I haven't ever found an explanation as to what exactly that relay is for....

 

In my 525I I lost all seat adjustment and tilt control.
I had the change the whole seat control unit in the drivers seat and everything started working again


cost me $100

 

This includes passenger side, heated seat buttons, and DSC button.

 

a thorough code check will surely tell you whats wrong. It does sound like a module as MCR stated.

 

No codes on the OBD2 anyway... There has to be something all these components run through.

 

Ok... Part of this issue is resolved anyhow. I found the trunk fuse for the seats etc looked a bit 'off' so I replaced it and the seats etc now work.

I still have this ABS Stability control crap issue with the instrument panel lite up like an Xmas tree.

 

And..... For some reason the ABS fuse in the glove compartment was MISSING!
