E87 120d ABS, DCT and Brake Warning sensors

[fayycarrim]

Hey guys,

I need some assistance please.
I have a 2007 120d.

The ABS, DCT and Brake Warning sensors came on last night just after starting my car.

I had someone read the codes for me, which I have attached below.


If someone could please assist me in where I should start and are these errors even related to my problem(when Google, doesn't seem like it)

Thank you in advance

Footwell module failure IMO.

Did you recently jump start or hook a charger up to your car?

FRM codes usually occur whenever there is a spike in voltage to the car and it corrupts the module and it needs to reprogrammed

Nope nothing of that sort. The car was fine, drove it earlier in the day no issues. When I started it at night and literally just pulled out of the driveway sensors went on.

Thanks for the response.

I will contact him.

Had a similar issues on my e90 a few years back and can't remember if I had the codes read but I replaced the wheel speed sensors and the issue was gone.

Don't know if it could be that again?

Not sure if this is it but when i bought my E87 120d  last year some lights went on and the speedo i think just dropped to zero when driving and would go back to normal a second later. Long story short, check the alternator charging rate and keep watching for a few minutes. If it drops from around 14,2 volts to around 12,8 or less for a second or two it is the alternator that is acting up causing all kinds of issues causing lights to come on on the dash and also sometimes losing engine power. I put in a new alternator and all problems gone. Has just come back from 4000km trip with the car and no issues at all. Replaced the old regulator on the old alternator and keeping it as a spare. Regulator was about R800. Must thank Forum member Stompie who also drives a similar car as mine for helping me solve my problem .

Hey guys,

Just to report back.
I replaced the ride height sensor and front right wheel speed sensor and all the warning lights went off.

So could have been one of them, just not sure exactly which one but at least the problem is sorted now.

Thanks for all the input.
