ASR LIGHTS ON.NO ACCERATE

Not without clearing codes. And if the check engine light is on due to an actual problem, it can turn the other warning light on too so you know those systems are disabled. Usually a problem with ABS or traction control will not turn on the check engine light.
Your owners manual would talk more about what the lights mean.
I would have the engine computer scanned for trouble codes first.

The abs sensors get clogged with brake dust try cleaning them and hopefully it should cure problem.

i would assume that there is a hardened steel sleeve "VERY HARD" that surrounds the barrel the same as the W140 model. the repair shop will have trouble cutting this off , like the novices at diesel motors in perth western australia. and will probably want to charge you around $3,000 AUD to replace the key and barrel. which collapsed in my case. jamming the key in the ignition. not bad for a vehicle that had cost $219,000 AUD , and had covered 220,000 km, when there countless thousands of 40 year old toyotas and holdens running around with the original ignition barrels. anyway , digressing , the switch that sits behind the actual barrel lock will no doubt fail not long after u change the barrel also. because i would say that the junk they manufacture for these over rated piles of trash (still riding on the reputation of their 1970's products, is about the same quality level as cheap rubbish componentry used in the W140 . "google search for W140 wiring harness there s a blog with a list of owners in the US with failed wiring insulation causing the copper wires to short out and in many cases cause engine fires. manufactured by Bosch to MB specification to be biodegradable, what a totally brilliant place to start , crucial electronic components, with severely limited life from the start.! , the ignition switch doesn't need to be cut out of the steel dash frame like in earlier models, and is not particularly hard to remove however the stealer will still try to slug u around a grand and tell u its a HUGE job. a friend of mine had my ignition barrel and switch out in 20 minutes after the switch behind the barrel failed after the dealer installed a new key and barrel and charged me 6 hours or so at $120/ hour.

1) try to use the self diagnose.
2) place ignition swtuch in the start position, the lights coming on
3) engine starts, the brake light sould turn off inmediately. the ABS ligth will illuminate for aprox 6 seconds.
4) test drive the vehicle at speed above 20mph for a few minutes. during the test the both test lights should remain off, if any one of the warninign light utron, take note of the condition.
5) stop the vechicle using the braking pressure.both light should remain offf during the stopping procedure.
60 place the gear selector in to PARK, and observe the warning lights, they should both be off.
God bless you

First of all replace bad wheel bearing !!! This bad wheel bearing causes ASR light ON.

ASR - Acceleration Skid Control system.
When ASR warning light blinking the system is activated itself for car acceleration skid control.

For today's typical high-torque engines, traction control (ASR) can increase both comfort and safety, particularly when driving on slippery roads or surfaces offering differing levels of grip. Traction control permits smooth starting and acceleration through the full speed range without wheel-spin or fishtailing.



ASR only operates in conjunction with the electronic accelerator (E-gas) and uses components of the anti-lock braking system (ABS). If one wheel suddenly begins to rotate faster than the others (slip), ASR intervenes in the engine management system and reduces power until the wheel stops spinning.
The ASR system represents a further contribution to active safety as it maintains vehicle traction and directional stability throughout the acceleration phase at any speed. In addition, it reduces tyre wear. Activation of the ASR system is indicated by a flashing indicator lamp in the instrument cluster.

The ESP system means the Electronic Stability Program. If the ESP lights on the dashboard permanently the ESP system is faulty. You must access the ESP Electronic Control Unit (ECU) memory for pull out all DTC (Diagnostic Trouble Codes), using diagnostic equipment connected to the data link connector of the car. Then you will be full informed about bad pieces (e.g.: front right wheel abs sensor interrupted, ...). After bad pieces replacement you will be able to erase all faults memored by ESP ECU, in other words reset the ESP system and turn off the warning lamp on dashboard.

Please do rate my response. Thnaks!

Believe it or not, this could be a mass airflow issue. The mass airflow can trigger the lights the ASR and the EPC lights. When i gets really cold, the airflow sensor sends signals to the CPU to readjust the air/fuel mixture.

abs light comes on and off during normal driving conditions also surges forward when the ligt turns off
