Warning Lights - Drive Off Assistant & Suspension Control System

CT_335D · 10-30-2014, 11:45 AM

Just picked up my car from BMW service. They just replaced the SCR Urea Tank do to a recall. One hour after I picked up the car, I get the following warning lights. The manual shows that following problems:

1.) DRIVE-OFF ASSISTANT HAS FAILED

2.) SUSPENSION CONTROL SYSTEM HAS FAILED

I also noticed that the ' DTC ' button was not working. Usually you can press and hold the button to turn off the traction control, but it didn't work.

I wonder if the service guys did something when they replaced the Urea Tank.

Did anyone else ever experience these warning lights?

sounds like your abs module is malfunctioning

If it's the ABS module that is failing, than it's not so bad.

I still have 13,000 miles of CPO warranty left on the car.

I was thinking they probably unplugged something and forgot to plug it back in, or they pulled on something and it finally came loose while driving.

Likely a rear wheel speed sensor unplugged.

I was thinking of the same thing. Either they forgot to plug something in or the plug was loose and after driving it for one hour, the plug backed out.

I dropped off the car this morning (BMW service) to have them take a look at it and they still haven't called me back.

The weird thing that I forgot to mention is that the warning lights go away after driving it for a while and then they come back. They also appear sometimes when you start the car, but sometimes they don't. It is very intermitting. Almost like there was a loose connector.

watch the dealer? trying to jip you

BMW service just called me to let me know my car is ready.

Looks like the problem was when they were reprogramming my car (installed BMW OEM alarm and it needed to be programmed to activate it) the tech had the steering wheel turn to one side. The steering wheel needed to be initialized before he started programming, which it was not. This screwed up the sensors, making the car computer think there was something wrong.

They initialized the steering wheel, reprogrammed the car and everything seems to be working, so I was told.

He mentioned the scr tank was replaced. This tank is under the trunk. Those faults all point to wheel speed sensors that are not in sync. Just an educated internet guess that it may be an unplugged rear wheel speed sensor.
