I have a 2012 535i x drive. It has the passenger restraint lift red coming on. The drivetrain malfunction yellow, the steering yellow, brake system yellow and parking break limited. In addition to this the speedometer doesn’t work. Please help anyone know why this all happened at once and what this could be before I bring this in to be looked at? Also is it better to bring to a BMW dealer or go to another shop. BMW seems more expensive. Any help appreciated. I did go get codes from Napa but they didn’t mean much to me.
Post the codes that you read from Napa.
Codes- u116d, p1526, u118a, no sup
A problem like this is difficult to diagnose over the web without having the car to test.
Check fuse number 72 (50amp), 2(5 amp) and fuse 40 (30amp) in the junction box on the right side of dash.
Those are the ABS/DSC related fuses. Usually when the abs module goes bad itll blow one of the fuses.
A new module will cost around there but you can pick up a used one based on your matching part number for alot less.
Is your car still under warranty by any chance? If not, i would try to take it to a euro specialty shop who focuses on BMW's.
Any update? Got these same errors today.
Figured it out. Fuse #2 was blown. Comfort Access / ABS fuse. Unplugged big plug on all door handles. Replaced fuse. No more warning lights. Will figure out which one was the culprit in the spring.
Also need a better shop
I also have a 2011 N63 750LI- and I am getting the lights in dash and notifications in the LCD module. Low power, etc. Have the u116d and u118a codes. I replaced the #4 fuse (PITA) and that did not correct it. I am slow charging the battery too. I think it may need to be replaced. It shows 12.48v when off, then only around 10v when I press the ignition button but do not start the car. This all happened after I got the message saying "increased battery discharge while stopped". I put the trickle charge on it overnight and then the next day went to drive it about 1/2 mile and it went into limp mode. Let it sit for about 10 mins- then it drove away fine, but the lights in the dash are still on. Now it has the reduced power and errors still. Anything please?
Did you leave something plugged in the car? The car will sense if something is drawing on the battery when the car is off. That is terribly low for battery output. It could simply be because something is drawing it down or could be a bad battery. Need to get the battery tested and go from there. I had battery issues recently. Look at my other posts
I’m having the exact same problem as you I mean identical just I have 2006 750 Li did you figure out the problem?Please share
