Is there a problem with the ASR on a Mercedes?
I guess that if you own a Mercedes, you will at some time get that problem! The ASR problem seems to occur in two distinct ways: It can occur while driving and gives the driver quite a start! The car goes into the LH mode (will be described later) and the accelerator pedal does not respond as before. It’s quite a ‘trip’ to drive the car.
Is there an ASR problem on my S500?
All readings ok: 120 ohms across the bus and continuity to all modules on the bus. After re installing the modules, which had all cooled down, the car was started, NO ASR lamp. Ran perfectly. Drove it for about 20 minutes, parked it in the sun (yesterday in SD, it was 95degs).
Why does my ASR light keep coming on?
ASR light started to come on about three (3) weeks ago. At first, I just could ‘fix’ it by turning the car off for 5-10 secs and then restart. Slowly it’s been getting worse. About 3 days ago, it wouldn’t reset by re-cycling the ignition. I drove the car for 5 minutes; when stopped at a red light, recycled the ignition.
Where is the ASR light located on an ABS?
But now the ASR light is on. So to kill that, insulate pin 29 on connector 1 of the ABS/ASR [N30/1] module by using a strong but thin tape. The MIL signal comes from this module and lights the ASR lamp located in the IC.
Is there a problem with the ASR system?
The ASR system has a tester that the dealer can read out to get the fault code. (In addition, I’m not aware there being two motors related to the ASR system… only a hydraulic control module.) I recently purchased a 97 SL320 that had an ASR fault and the problem was a relativley cheap brake switch.
What was the problem with the ASR on my 1992 500SL?
I started having a problem with the ASR system on a 1992 500SL. I was driving on the highway when the ASR sensor light came on and the car defaulted to a “limp home mode”: The engine output power was reduced and I was able to make almost home; after stopping at a red light the battery light came on and the car completely stalled.
Why is my ASR not working on my Mercedes 500SL?
All the wheel speed sensors checked out fine. If you are experiencing any ABS issues in addition to ASR, either the brake switch (separate from the brake lights)or one of the speed sensors could be intermittently failing. I have also seen a few threads with regard to low voltage causing similar problems which could be weak charging issue.
What to do if your ASR light is off?
I restarted the car and the ASR light was off and the car drove normally home. Two motors relating to the ASR system were replaced by the service shop: ($ 1,500 Parts & Labor).
Why does the ASR light go off when I stop the car?
2) The ASR light comes on, tachometer indicates 1000 rpm but can drive the car even though it’s in the Limp-Home (L-H) mode. 3) If the ASR is on, drive for 5 minutes or so, stop, re-cycling the ignition and the ASR light will go off and STAY off until I stop the car and let the heat build up in the engine compartment.

Why is the Bas light on on my W202?
That light could be caused by any number of things, including one of the four wheel speed sensors, the yaw sensor, a steering angle sensor if equipped, steering control module, abs control module, calibration being off, etc. Thanks for your thoughts. I do have an I dependent repair facility that’s can scan the car for $130 diagnostic.
When does the ASR light come on in my car?
Was able to find a compatible EA/CC/ISC [N4/3] module to test in my car. Well, it worked for a while! Same thing after 6 trips or so: If the car is stopped after high speed driving and then into stop-go traffic for 10 mins or so, ASR light comes on. The engine heat builds to 100C or so when the key is switched on.
What are the symptoms of a bad mass air flow sensor?
3 Symptoms of a Bad Mass Air Flow Sensor. 1 Your Car Hesitates or Suddenly Jerks Forward While Accelerating. A bad MAF sensor can cause your vehicle to experience poor drivability issues such as 2 Your Air Fuel Ratio is Too Rich. 3 Your Air Fuel Ratio is Too Lean. 4 Your OBD-II Scanner Gets Code P0101.
What does ABS Bas ASR light on Mercedes mean?
What do ABS BAS ASR lights mean? If any of these lights turns on and stay ON once you start to drive the car it means there is a problem with one of the following systems or related sensors. Step 1: Ensure that the main battery on your Mercedes-Benz is holding a proper charge. Mercedes-Benz cars are very sensitive to low voltage.
Why does my Bas light come on in my Mercedes Benz?
To reset the lights, start up your Mercedes-Benz and turn the steering wheel all the way to the right, then all the way to the left. Do this a couple of times. Turn off the engine. Restart. Brake Light Switch may cause BAS / ESP / ABS light to come on. It is the most common problem with Mercedes-Benz cars.
Why does my Mercedes Benz hesitate to accelerate?
-Air filter and throttle body are clean. -I haven’t changed the MAF in the 2 years that I’ve owned the car, and i tried running the car with the MAF unplugged; the problem was the same except now the idle was constantly low and rough. The problem is slowly getting worse. I’m contemplating ordering a new MAF or maybe a set of new coils..
An old battery can be the primary cause of BAS/ASR lights staying on. It is common for BAS / ASR lights to come on with a dead battery. It takes a while for a discharged battery to charge fully. Your Mercedes-Benz battery should have the date it was manufactured stamped on top or the side.
