ABS and ESP light on (after replacing sensor)

**jonsaudi** · 08-21-2012 08:20 PM

Ok. First off, I've been having intermittent issues with the ABS / ESP light turning on followed by speedo that stops working. So I had it scanned and found out that the left front wheel speed sensor was the culprit. After replacing the sensor with an aftermarket part, while on idle, the ESP light would stay on, the speedo needle moving up and down, then followed by the ABS light and eventually speedo needle stops moving and working. How can I get this cleared and fixed? Any ideas? TIA.

Have you been able to check for codes again?

**JEENYUS** · 08-22-2012 10:05 AM

you'll need to get your car looked at via VAG-COM, but it sounds like your ABS is about to take a dump on you my audi friend. Mine used to do the same thing.

**SlickFix** · 08-22-2012 10:30 AM

Brake light switch? Might be worth a try, as it's very easy to do, and inexpensive.

**RSicks** · 08-22-2012 11:13 AM

Not a brake light switch. When mine went out I got no error lights. Just brake lights staying on and no cruise control. Sounds like a bad ABS module. Check my old thread for info.

**SlickFix** · 08-22-2012 11:21 AM

I beg to differ. When the brake light switch went bad on my wife's Avant, the symptoms were the ESP light coming on intermittently when starting up, and intermittent loss of throttle response for seconds at a time. I didn't say that it couldn't be the ABS module, I just said it would be smart to try a simple fix like this first. YMMV.

**jonsaudi** · 08-22-2012 08:07 PM

Thanks for the replies so far. The car was scanned via VAG-COM which led me to find the problem which was the front left wheel speed sensor. I don't think it's the brake light switch b/c I had that happen once and I know the indicator of that is usually the rear brake lights staying on even after depressing the brake pedal. The problem with mine this time was, after replacing the wheel speed sensor, the ABS and ESP light stay on as compared to prior to the replacement, the ABS/ESP light would come on sporadically. I'm thinking b/c the sensor is an aftermarket may be causing the light to come on, ya?

**RSicks** · 08-23-2012 11:40 AM

Swap the sensors from left to right on the front. Clear codes and see if it comes back or if it shows up on the right front sensor. If it comes back as a left front sensor even after it being switched, its more than likely the ABS module. If it doesn't come back or it says the rights out... you know its the aftermarket sensor.

**jonsaudi** · 09-05-2012 11:52 AM

Bump.

One thing I missed out....I haven't cleared the fault code since replacing the sensor...Could this cause why the problem still exists after replacing the sensor?

**jonsaudi** · 09-12-2012 10:00 PM

Bump.

So I had the ABS module rebuilt, thinking it would be my last hope to get this darn issue fixed. So I received the rebuilt module, from cheapabs.com, (Very quick turn around, btw. Highly recommend) but the problem is still there. After re-install, the ESP light came on followed by ABS light after a couple of seconds, then remained on. I drove it around the block a couple of times, but to no avail. What else do I need to do?!?!?

**SlickFix** · 09-13-2012 06:06 AM

Did you pull the brake switch out and see if it was sticking at all? I know that you replaced it awhile back, but it might be worth checking again.

**Nammo** · 09-13-2012 08:50 AM

I have similar issue with my 2003 A4 1.8T. Code indicated wheel sensor so I had that replaced. Code still comes back.

00290 - ABS Wheel Speed Sensor; Rear Left (G46)
30-10 - Open or Short to Plus - Intermittent

I've had a shop check the wiring from the ABS module to the sensors, checked the sensors, checked the ABS selector rings. Everything checks out. Next step for me would be to replace the ABS control module however a new one I'm told is like over $2000. A refurb/rebuilt one would be $300. However, sounds like that did not solve your problem. Mann...this problem blows considering the resale value of the car is not much anymore.

^Can you tell us what code # you had (have)?

^Generally ABS systems do a self check at start up, and if everything like sensors is good, light will stay off.

I'm sure he's getting:
00283 – Front Left ABS Wheel Speed Sensor (G47)
30-10 – Open or Short to Plus – Intermittent

Since he said it was his front left wheel sensor. Mine will act up on start up, and can be reset by restarting, but will randomly turn the lights on at any dead stop. So it's not the self check atleast for me.

I'm sorry to hear the rebuild didn't fix this because that's my next route. Heres my battle Clicky!

I am getting ready to replace the module next week, so this post scares me a little :(

If the ABS light is on, there is a code stored. Plain and simple. No need to guess what the problem could be. The light is on in reference to a very specific (if sometimes puzzling) diagnostic trouble code. Read code, diagnose, repair.

^Thank you

We await real code(s).

This condition isn't so easily diagnosed by the code. Mine throws the code on the speed sensor, however 2 shops have looked at it and its not the speed sensor. Even had it replaced. The problem is also intermittent so the code will clear by itself, and come back. He's experiencing the same problem that I am experiencing, only mine is reporting left rear sensor, his is left front.

I'm in the same boat as you RSick. My next route is a rebuilt ABS control module.

**sadpandas** · 09-13-2012 11:23 PM

Bump for all of us... Shop just made sure all my wires were intact and in fact connected. They cleaned the area as well. I was also told it was my abs sensor that is bad but the brake switch problem seems to be an issue with a lot of folks as well. So, it could either me the ABS sensor itself, the brake switch or the ABS module? What else could be causing these issues? This my code:
Address 03: ABS Brakes
* *Controller: 8E0 614 517 A
* *Component: ABS/ESP allrad * * *1726
* *Coding: 04497
* *Shop #: WSC 06435
3 Faults Found:
00283 - Front Left ABS Wheel Speed Sensor (G47)
* * * * * * 30-10 - Open or Short to B+ - Intermittent
01119 - Gear Recognition Signal
* * * * * * 35-10 - - - Intermittent
01826 - Sensor for Steering Angle (G85): Supply Voltage Terminal 30
* * * * * * 35-10 - - - Intermittent

Anyway, seems to be happening/ has happened to many people on this forum and when the issue is fixed it is usually one or a combo of the above mentioned parts being replaced or a wire not touching the sensor correctly or being pushed too far in or just plain dirty..... Lastly, its a bummer seeing your dashboard lit up like that it is unsafe if the ABS isn't working properly. Sorry about the thread-jack-rant just had to go off. I feel your pain. Im upset just typing this out....

**macguyvermedic** · 09-14-2012 12:44 AM

Sidespar "Matt" fixed my ABS sensor almost 2 years ago and has been flawless since. I was pulling the exact same codes and tried changing the front L ABS sensor without success. I sent the sensor off to Matt and in under I week I was back in business. The bonus side is you don't have to get your module recoded if you repair instead of replace your original. I drove the car the entire time the module was out without an issue. As soon as it showed up on my doorstep I installed it and the lights went off and have remained that way. :)

**sadpandas** · 09-14-2012 01:05 AM

Just googled him and then emailed him. seems hes been doing this for a while BUT the last posts i could find were from around 08-09. you had yours done 2 years ago... heres to hoping he emails me back...

**macguyvermedic** · 09-14-2012 01:07 AM

I had it fixed in March of 2010.

Please keep us posted if he's still doing repairs to the ABS modules. Thanks!

**jonsaudi** · 09-14-2012 11:06 AM

UPDATE:

Ok, so I decided to remove the new aftermarket sensor, and popped back the old original sensor...NO more ABS and ESP lights!! Drove it around town for about 20 miles and everything was in working order. I'm guessing the ABS module has malfunctioned and the original sensor was ok to begin with. Also, the new rebuilt module probably was not programmed to read the new sensor, therefore signalling a failure. The ABS module needed to be repaired for it to read the original sensor and to function like it's suppose to do. I hope and pray that the problem is actually fixed and that this issue will not come back again... I'll keep everyone posted should the issue return...

Nothing back after email sent.... Someone else want to bother him?

**macguyvermedic** · 09-24-2012 12:12 AM

I'll shoot him a message for you. I'll let you know if and when I hear back from him.

**Allstar84** · 09-27-2012 10:09 AM

I'm having the same issue. Please update!

**macguyvermedic** · 10-04-2012 12:22 AM

I still haven't received a response from Matt. Looks like there is another guy, k0mpresd, who fixes these as well. I'd shoot him a PM if I were you.

Here is a link to a similar discussion he participated in. http://www.audizine.com/forum/showthread.php?t=233293

Matt actually got back to me today. going to ring him up tomorrow see whats good. ill report back.

**macguyvermedic** · 10-05-2012 10:38 PM

Sweet, Matt was great to deal with and had a really fast turn around time. Keep us updated..

**DiertyEuroSpec** · 10-06-2012 05:59 AM

I think I will also be sending out my module to Kompressd. Hopefully get a positive result and here's to AZ

**RudEb0iA4** · 10-06-2012 02:17 PM

Care to share Matt's contact info? Started recieving beeps/dash lights about a month ago. Dealer says ABS module needs to be replaced based on fault codes. For 1.9k ill take my chances or have mine repaired.

**sadpandas** · 10-13-2012 06:46 PM

yep as soon as i get back to the studio i will send you a pm.

**RudEb0iA4** · 10-13-2012 06:50 PM

Feeww I just got my module back from k0mpresed today and it solved my ABS ESP problems. After replacing both brake sensor and the front drivers speed sensor I am very glad that I got resolved for $50 < 1.9k

Dealer price. Also this can be done following the DIY k0mpresed posted earlier this week. Stoked to have those annoying lights gone!!!

**VectorG** · 10-13-2012 09:11 PM

I have a ? On this. On my A6 when i got it these lights were on and the drivers rear caliper would stick so i cleaned it and replaced the brake switch, rear sensors and rings and i get these lights intermittently, some times stay on constantly some times not. Cruise still works properly 600+ miles. My brakes will lock up some times though when stomping on them. All this lead to the Module or another sensor? Thanks

Sent from my DROID RAZR MAXX

**DiertyEuroSpec** · 10-14-2012 04:58 AM

Big

to k0mpresed!!

And to VectorG after using the cruise control one of the times the module was "intermittently" working...I used the cruise control as I was getting off the highway went for the brakes and nothing. I almost shit a brick. Luckily I was able to slow down enough with ebrake until the brakes came back but needless to say I haven't even thought of using cruise control since...but maybe now
