Traction control, ABS and Brake Warning lights all on.

[Alfie Noakes]

Whilst driving today I got three loud beeps. When I looked at the dash the Traction Control, ABS and Brake Warning lights were all on. I stopped the engine and restarted it. On turning the ignition only the traction control light comes on but once I get to about 10mph the other two come on and I get the beeps.

• I have checked the brake fluid level.
• I replaced a brake light bulb about two weeks ago.
• The NSF tyre rubs the arch liner on full lock.

Other than that the car drives normally, the brakes appear to be fine and all the pads are good.

Any ideas?

It may be a faulty ABS sensor. A full diagnostic check will hopefully point you in the right direction Rob.

Ditto from me, I had the same issue a few years back Rob, scary at the time but turned out to be a simple fix in the end .... VCDS showed an intermittent fault on the rear right ABS sensor that was finally diagnosed when it failed completely ... I went for aftermarket and replaced them all for peace of mind with no problems since.

I have had the ABS and break warning lights coming on when my X reg 1.4 keep coming on. After visiting my Audi garage, the sensors were checked but they keep coming on after driving a few miles. The garage can’t find any fault but getting the lights to stay off is proving impossible. Does anyone have any tips or advice as it is unlikely to get through the next MOT.

Take your car to a specialist. Gary at B&F Autos in Hounslow is probably the closest A2 expert and comes highly recommended by quite a few satisfied customers from this forum.

Hi Sals, I'm guessing you paid an arm and a leg to have it plugged in at a dealership even without a positive diagnosis ... if you think it could be the sensors and were willing to take a punt you could replace all four for around £70 with aftermarket Febi Bilstein, they're probably still the originals on your car and could be deteriorating ... alternatively if you know anyone with known working ones to try.

EDIT ... This is a DIY job, only a single bolt holds it in place with an allen key head.

Thanks to both Steve C and Tomscar for your rapid replies. I am going to contact Gary at B&F. With regards to the sensors, I had the sensors reconditioned last November as they are no longer available. I gave up with main Audi dealers about 10 years ago due to the very high charges. I found a good independent Audi and VW specialist locally but he has done as much as he can and is hoping after 21 years of A2 ownership, I will trade her in but I really don’t want her to go for scrap.

Hi Sals, your welcome ... just curious if we're talking about the same parts, I can't see that it's possible to recondition them ... my local Audi garage was able to supply ABS sensors just last month at £90 each ... I declined (not including fitting!)
The original part number has changed but the new numbers are the same part ... they are common across a lot of the VAG range and identical to the ones in my Skoda Citigo.
I bought mine from Amazon and can send you the links for the set if required.

We had the same multiple Warning Lamps on our 2003 1.4SE Petrol. They were / are all spurious. They all go away after Stopping the Engine and Re Starting According to The Maestro ( Timmus ) it is just that the A2 “ brain “ sometimes gets confused by other Alarms / Warnings and “ has a paddy “.

I must admit I am confused. Another thread I looked at said the front sensors were part of the wheel bearing???

Just to add, the tandem pump may be a little flakey but not much. During the lockdown, it was parked facing uphill for about a week and was a problem to start, since then it's been fine.

Hi Alfie, the wheel bearing has a metal disc and would guess the ABS sensor picks up a rotational speed from this disc ... but they are separate items and can be replaced individually.
Edit ... the metal disc is permanently attached to the bearing I believe, so if the disc is damaged would need a new bearing.

Hi Everyone,
Thanks for your help so far.
My "man", came over last night and plugged his system in and came up with the following fault code:

01130 - ABS Operation Not A Plausible Signal - Intermittent

See attached. Any ideas?
Thanks
Rob

I would have it scanned by VCDS firstly , see map for nearest member, then I would remove the offending wheel & clean the rear of the bearing where the sensor protrudes through with brake cleaner & a rag this ring is magnetic & will attract brake dust & mask the segments on the ring.

Hi Alfie, this code sort of points you towards either a faulty ABS sensor, or a wiring issue between the sensor and the control module or the magnetic ring on the bearing broken or dirt/ interference ... are you still getting the warning lights on the dash? ... in order of cost/ time, do as KP suggests above, if that doesn't work then change the sensor ... try and get a proper VCDS scan or you will end up replacing parts until you get to the cause.

 

[Alfie Noakes]

Are you saying that the VCDS scan can highlight the offending component?

Also, the nearest member with a VCDS is 30 miles away, would the car be safe over that distance?

There are many VAG specific codes. The standard OBD code set is a minimum code set which all car maker agree to support. Each maker then adds their specific codes to that set. VCDS, and OBD Eleven are VAG specific. Other scanning tools may not recognise, or even request those codes. If their are additional codes, VCDS and OBD Eleven will show them.

Hi Alfie, I'm learning as I go ... but yes, VCDS pointed me specifically towards the back right ABS sensor and told me it had failed, I swapped for the identical one from my my Skoda Citigo (with the updated part number and common to many in the VAG range) before buying a Febi Bilstein replacement.
Regarding safety, are your brakes working, are the warning lights permanently on every time you start up or is it intermittent as indicated? ...
Only you can decide whether it's a risk but I drove mine 250 miles back from England.

Thank you, Tom,
That is really useful. Are you able to tell me which bits you bought for the VCDS? I have looked on the Ross-Tech and Gendan websites and ended up completely confused.

If the ESP light is on, you've lost all ESP functionality, including ABS.
