My 545 has been at the dealer for 3 days because I keep getting the "Service Engine Soon" yellow light and the CID message "Increased Emission". The problem occured 7 times in 3300 miles including when I picked the car at the factory! This typically happens after I have driven the car for 2+ hours and the indicator dissapears after the engine has been cooled for 24hrs. I did 4 dealer visits for this problem, they updated the DME software but aren't getting anywhere. Anyone else with this problem?

 

It happen twice to me. They're excuse is a GLITCH in the CPU. Has not happen in over 6 month. I have a 545i 2004 Since 11/03

 

IF they have tried to fix the car 4 times and the car is still doing it you can inact the Lemon Law and have BMW do a buyback. You then can get a new 5.

 

do a search, because I recall seeing others with this issue and if I remember correctly, it was easily fixed with a software upgrade.

 

I had service engine light came on 2 times. What I did is make sure the fuel cap very very tie every time i fill up gas. I also did software upgrade to 12.x (not sure what version I have, but my RDS is no longer there and AC icons are gone).

After that, my "service engine soon" problem seems fixed.

 

This has happened a few times with mine too. I was told that is was because I removed the gas cap with the key in, an easy fix anyway.

 

I have been having sort of the same problem, It started out doing it once in awhile and then kept doing it more often and then it started saying to shut the car off imediately. They gave me a 745i for a loaner. If it doesnt stop happening by 3 times, i will do the lemon law, i love the car, but hate the problems

 

Did you tho?

I dont think thats correct, there just coming up with some lame excuse.

 

Has it happen once and they told I must not have tightened the gas cap. Code was reset and has not happened again in almost 9 months.
