BAS, ASR Problem - Benzworld.org - Mercedes-Benz Discussion Forum

Hi,

I have a Mercedes C200 1998 2.0 model. Over a year ago the BAS/ASR light came on in the dash. After a diagnostic at a local garage i replaced the OSF ABS Sensor and the problem was fixed. Then a month later the light came on again and i replaced the NSF ABS Sensor and again the light disapeared.

Now a year later the BAS/ASR light is permantly on again. I had another diagnostic done and the garage said it could be the NSF ABS sensor or the ring. My mate cleaned the front and rear sensor and ring, but the light is still on.

Can someone tell me if it could be the sensor or something else, as the NSF sensor i replaced was a genuine one. Its hard to beleive that could be faulty, as my mate also did a omes test and showed readings to be fine.

Is this a common problem on the C Class W202 models?

Do a search in teh forums for "brak light switch" that's the part you need to replace to fix that BAS/ASR light. It's a $20 US part, a screwdriver, and 15 minutes to fix.

Get a new battery! DONE!

I changed the current battery, but still BAS/ASR light on. So I'll try to replace a brake light switch. I'll report the result.

Hey all. This weekend I am inspecting symptoms of the same problem: ABS light on.

Going through the usual suspects, and while checking the brake pedal switch, I was wondering how that foot well panel pulls down. It seems to loosen easy but that hood release lever is a big pain in the butt. Is it supposed to stay in position, or do you disconnect the cable from the red lever? Thanks for any tips.

The hood latch stays attached. There is a screw behind the latch, real tricky to see. Twist and turn and it will come out.

Hi. The fault codes stated brake switch. So I had it replaced. The ABS light went out permanently, but the cruise control still doesn't work. Any ideas? Thanks.

Ironically I had my dash lights come on the other night. I paniced a minute and then realized I was down to drops of fuel. In my old Vette it would light up the dash when out of fuel. As with that car, once I filled the tank the lights went out and all is fine again. I don't know if that's by design, a fluke or dumb coincidence, but I thought I'd share it in case it helps anyone.
