Possible traction control issue?

[jupe777]

Had 4 warning lights come on while driving yesterday, I can't do anything with the traction control button. Any ideas please before it goes to BMW?

[billyboysm3]

Thats a wheel sensor, you have no abs. I wouldn't bother taking that to BMW.

[billyboysm3]

Where are you based?

As Billy says ;)

[Chappers]

Is the TPMS and Gearbox warning on too? Why would that be?

[Mike R]

When I had the same issue, there wasn't even a problem. For some reason the ECU just decided to stop communicating with one of the front sensors. Typically it happened on the way to the 'ring :banghead: . Fortunately one of Toughy's friends had his laptop with BMW software and lead with him and plugged it into the OBD port and just told the ECU to start communicating with the sensor again. This was over 2 years ago and the error has not come back since. Fingers crossed it is just as easy for you :).

Thanks for the replies guys. Billy I'm in Bedford.

What is TPMS Chappers?

From the replies I'm thinking nothing too serious then.

Tyre Pressure Monitoring System... Kind of a fallacy as there aren't any real sensors.

[Chappers]

oh I know, sorry I was responding to the question above about what TPMS means.

I would get the errors read and deleted with INPA. Then drive a bit, if they return, read again and check whats wrong. Most likely the wheel speed sensor is the culprit.

What is the score with these sensors? Are they just off the shelf items from BMW ie pick a new one up and replace it? I take it once replaced it the errors will need deleting to get rid of the lights.

I got the DSC and yellow brakes (- ?) icon come up on mine today.

Presumably they are just caused by dirty contacts rather than failure. Are they are DiY fix for tinkerers or just for 'experts'?

Words from the wise appreciated.

Pip

Ps not my car as I have only reached ~40,000 ;)

[jupe777]

As it turned out the issue with mine was not the speed sensor but a wheel alignment sensor. Elms reset it and all is good again.

[Monkey]

Could be a number of reasons, something you can do yourself is disconnect and reconnect the pressure sensors on the brake master cylinder. There are 2 of them, a little bit fiddly. Other than that you'll need to get the faults read I'm afraid.

Thank you again Monkey. Looks like I will be down to see you sooner than I think :thumbs:.

Will be in touch.

scan it and see, as mentioned it could be many things!!

I had the same 2 lights on in my E46 330D daily, turned out to be a code for an electrical fault with the yaw sensor

fired a replacement yaw sensor in and been fine since (yaw sensor doesn't require a reset/calibration or anything)

[patphnx]

Just had the same same thing on mine. Turned out to be the pressure sensor on the brake master cylinder.

Seems like these sensors go wrong more often than the things they are sensing!

[Pip1968]

Just to add to my last post. Started the car up a day or so later and no warning lights on. So could have just been my enthusiastic drive down to one of those driving experience days. I should add that I was just watching it all unfold at the BBC track.

So anyway surprise surprise vehicle electrics are temperamental. A sign of things to come on new cars :rolleye:

[Brendanmck]

Snap . Have the same 4 lights on at the moment just finished my subframe reinforcements and rear axle rebuild when all was put back together i had those 4 lights stay on guessing I need to plug in to a computer also .

[Pip1968]

Just wanted to say that the DSC fault which I encountered was fixed by replacing the DSC pressure sensor on the DSC unit and was sorted out by Monkey at Chandlers BMW in Brighton.

Have had the similar issues, the same two lights come up after about 20-30mins spirited driving but ONLY after Track Mode is selected... There's a 'bing' and then Lights come on and won't go away until the car is switched off for a few hours. Lights are usually gone on restart and then they come back on as per above, but only if track mode is engaged.... Thoughts on what sensor it might be of those suggested? Feels like the steering is heavier (actually almost better) when lights have come on...

[select]

Not sure about the causation with the track mode, but it sure sounds like a faulty wheel sensor. I would get your codes read, so you know what exactly is the fault and if its indeed one of the the wheel sensors, which one to replace.

Have you tried driving without the track mode and see if the problem comes back?

Yes, strange huh, lights dont seem to come on if track mode is not engaged...will get bmw to read the codes and go from there...

My bid on it also.
I get the same issue and same warning in the dashboard. I ordered and replaced (myself) both ABS pressure sensors and the problem get solved.

Thanks Olive, ill give that a shot, do you happen to know the part numbers?

[select]

Should be 34 52 1 164 458. The DSC/ABS system uses two of this sensor. One is around 80£ excl. VAT. So you may want to get your codes read, before you end up changing them for nothing.
