    I have the same problem. Sep 2003 Allroad 2.5 TDI. The car is currently in the Audi Dealer being fixed under the extended warranty (only had the car a week). I was told it is something to do with the engine management and they're replacing an injector. I'll keep you posted.

    I have the same problem with a 2004 Allroad but my lights do not go out unless I turn the car off and restart. Even then the usually return. Did the dealer fix the problem? Mine tend to come on after I brake so I have assumed this was related to the braking system.

    My 2004 2.7T had the same problem yesterday on our way to Yosemite. I stopped the car. Turned off engine, restarted and noticed the autocheck function did not work. Kept on driving until I had to refuel. This time the auto check worked and the warning lights went off. So far, it has happened four times in the past 2 days.

    Under normal conditions, I periodically get the Air Suspension Level, ESP and ABS lights on the dash at the same time. All three lights stay lit. If I turn off the ignition and start the car again, the lights usually stay off. Mine is a 2004 Allroad 2.7T. Anyone have any ideas? Is it in fact the brake light switch?

I had the brake light switch replaced by a local dealer. Cost was $140 and it fixed the problem. Have driven the car for two weeks since and no lights and all systems normal.

My 2003 Allroad has the same problem. As soon as I brake hard once, the no ABS, ESP and Level warning lights comes on and stays on until I restart the car. I've had the car for 1.5 years and this problem has been on and off. Whenever I get ready to go to a dealer the problem would disappear on itself for a while. Last time it happened just a few days ago. We had first snow (in Toronto) that day and the roads were very slippery...just when we need ABS and ESP the most..IT WAS NOT WORKING!!! The Allroad was sliding sideways like I was driving the cheapest car ever. I almost rear ended a few cars. The ABS just wouldn't turn on. Last year this car ROCKED during the winter month. I will take it to the repair shop shortly. I hope that its just a brake switch and the repair will not cost me a fortune to fix.

So I brought my 2004 allroad to the dealer today....As soon as I described the problem to the service advisor, he said it's a brake switch that intermittently sends the faulty signal to the computer. Anyway, they replaced the brake switch, part number 1K2-945-511 --NAR. A $6.19 item. So far so good (today only) ABS, ESP and Level warning lights....will keep you guys posted.

ABS + ESP lights staying on dashboard

wow no year car, now that is a challenge , no?
abs is first.
first- first are brakes.
abs stuck on key on and running full time right?
so check brakes for damage or worn out.
brake fluid level not falling? look yet? look when checking oil every time.
abs can not work on cars with bad brakes, (its not god like)
then check for ABS sensor damage and its wires. under car.
then scan the ABS. got errors, sure you do.
but what? you didnt scan it first.
or read the manual> RTM?
its only 4 bucks to read it.

How do i reset the abs and esp light on an Mercedes e270 chi from 2004

You can reset all lights by disconnecting the negative lead to your battery for about 30 seconds. This will reset them but if the problem is not fixed they will come back on in about 50 miles.

PRE-DIAGNOSTIC INSPECTIONBefore diagnosing ABS/TCS, perform a comprehensive visual inspection of system as follows.Check ABS/TCS wiring harness connectors for looseness. Check harness routing; pay particular attention to wheel speed sensor wiring harness routing. Check fuses No. 1D, 5B and 6B in instrument panel fuse block. Check fuses No. 1 and 2 in underhood fuse block. Check brake fluid level in master cylinder reservoir. Check brake fluid level in Pressure Modulator Valve (PMV) assembly reservoir. Ensure parking brake is fully released. Ensure parking brake switch is functioning properly. Always perform ABS/TCS system functional check before using DIAGNOSTIC CODE CHARTSThe EBCM/EBTCM has self-diagnostic capability, which can detect system failures. Fault codes stored by EBCM/EBTCM can be displayed using Tech 1 scan tester. There are no provisions for flash code diagnostics.Begin ABS/TCS diagnosis with PRE-DIAGNOSTIC INSPECTION procedure. If failures are found during pre-diagnostic inspection, perform necessary repairs, and proceed with ABS/TCS FUNCTIONAL CHECK. See Fig. 5 .If no failures are found during pre-diagnostic inspection, go to ABS/TCS FUNCTIONAL CHECK. See Fig. 5 . The ABS/TCS FUNCTIONAL CHECK will either indicate ABS/TCS is functioning properly or direct technician to various diagnostic procedures such as diagnostic charts, symptom diagnosis or BRAKE warning light diagnosis.CHART D - TRACTION OFF WARNING LIGHT ON CONTINUOUSLY & NO DTC SET (BUICK WITH UH8 OR U2A INSTRUMENT CLUSTER)Circuit DescriptionWhen ignition switch is first turned to RUN position, EBTCM goes through a self-test, which lasts 2-4 seconds. During self-test, EBTCM commands TRACTION OFF indicator warning light on. Powertrain Control Module (PCM) can also command EBTCM to set a Code 75 which will illuminate TRACTION OFF indicator.Traction control switch is located either on instrument panel center trim plate or driver's front door trim panel. Switch allows driver to select traction control mode (on/off). When traction control system is turned off, TRACTION OFF warning light comes on.EBTCM monitors transaxle temperature through

ABS warning light stays on

Did you check the brake fluid level?

You may have either a bad ring gear which the sensor picks up the signal from - or a bad sensor for the ABS - I'd pull each wheel and inspect for missing teeth on the gear the sensor reads off off - and look for bad wires on a sensor - perhaps one is not gapped right.

Seek service manual for propper gapping on the sensor to the ring gear. Worst case scenario - ABS accumulator/pump could be faulty. Be advised that whils this ABS light is alluminated - the ABS is not activated - you are on BASE brakes only and most likely your traction control (ESP or TCS) is disabled as well.

I highly doubt it's going to be anthing more then a wheel speed sensor or indicator (ring gear). Disconnect your cables battery to reset the ECU for 5 minutes, then plug it back in, that'll clear whatever codes you have, if the error returns... then you should really look into it.

Hope this helps.
