Brake/Traction warning lights issue.

[Stu23]

Hi All

We've got an issue with the z4... this little lot all came on at once. It doesn't seem to have affected the drive at all, but I'm not pushing to find out what's systems are not working!

Any ideas?

It could be a number of things you need to get the codes read

The same thing happened today with mine.
Same lights on but without the "low tyre pressure".

What year/engine do you have?

My engine is 3.0si E86 coupe.
Apologies for hijacking the thread.
I can start a new topic.
Probably both op and me have the same problem.

Owners manual tells you what the combo of lights mean; unfortunately if the ABS light also lit it usually means the unit is dead/dying. Do the warnings go away after you restart the car? Mine has thrown those codes before (minus the ABS light) however they go away with a restart. They haven't reappeared in several weeks (touch wood).

 

[Monkeydonkeyratmagic]

Very rarely does it go away. Mine did once or twice but ended up permanent. Even after leaving the battery off for 2 weeks.

Just back from mechanic and can confirm abs unit is the problem.

Google ecutesting. £190 and they'll repair it and warrant it for life. You can use the car when turn it around but you'll have no Speedo. Quite quick though. About 4/5 days. Or ask Mike, he can do the repair too.

I can do whilst you wait, need to know the codes though.

Hi Mike
A bit difficult as i am located in Northern Ireland.

 

[ph001]

Normally if you get the tyre pressure warning light on it relates to a wheel speed sensor so am a bit surprised at the ABS unit fault. Not sure why the tyre pressure warning system wouldn’t work with an ABS fault.

HI All. Thanks for all the replies.

Car is an 04 3.0i auto... sorry don't know what engine that would be.

Lights stay on permenantly, even after disconnecting the battery and shorting the leads together.

Appreciate the offer to help, but I'm in Wiltshire, so a long way from Ducklakeview.

What ABS unit is it? I assume just an electronic control box, not hydraulic, if I can drive around without it

Yes you can - BUT no ABS and no traction control... And probably no insurance cover in the event of a smash if they find out..

Oh, and MOT fail.

Wasn't planning on doing it, Mike, just referencing the earlier post by Monkeydonkeyratmagic. MoT due in a couple of weeks, so it needs fixing pronto.

I'd be round to your place poste haste if you weren't almost 200 miles away.

Pop up, jump on train to Manchester/Liverpool, see some sights and come back to a fixed car..

[Stu23]

While a fixed car sounds wonderful I'm confused by the idea that there's interesting things to do in Manchester or Liverpool...

That's the exact combination I had. The tyre pressure one was confusing.

Mine was caused by doing track rods. Recalibrating the steering angle sensor at your suggestion finally cleared all my lights

 

[davros]

I also had this combination of warning lights. It turned out to be the front left speed sensor, which took about 30 minutes to replace. All the warning lights then cleared after a short test drive.
