My car was running fantastic until I was going on my lunch break today . Hopped in the car and started it , tire light came on, check engine light came on
air bag light going on and off , fuel gauge cycling between full and empty (its full) I'm getting an inactive ! on my TPMS , checked my tire pressure and
tried a reset and the inactive came back .
This all happened simultaneously , with absolutely no issues on my 58 mile commute to work . Car was running great . Any thoughts on this , or anyone that
has had this issue I would greatly appreciate your input .

 

Is it the original battery in the car? Have it tested. If it is the original you probably need a new one as a failing battery can create all kinds of electronic gremlins.

 

No it has an Interstate in it now , funny thing is when I bought the car I cleaned the battery terminals , checked the air filter etc. and when I reconnected
the battery it fried the foot well module . That was covered under an extended warranty thank goodness . I will check the battery , it does seem weird
this all occurred at the same time .

 

^ this..

 

Ill 3rd the Battery notion. These cars a picky about the correct voltage.

 

Battery came back perfect .

 

Mysteriously , all the lights and warnings are off as of this morning , except the check engine light . Im heading to a local bmw repair garage this afternoon to see what the code is .
WTF , Electrical Gremlins ???

 

These are the lights that were flashing on and off with chimes going off too , no dash lights , blinkers would go on but
not shut off ... I wonder if there is a bad ground somewhere .....
