Hello,

I have a 1998 E320 and a couple of months ago my Check Engine light came on. I took off the battery terminals for 10 minutes ... the light went away. But it surely came back on after 30 minutes or so.

My car has about 80,000 Miles.

A couple of weeks ago, all these warning lights came on:

1. Anti-Lock Braking System - ABS
2. ASR
3. BAS
4. ESP
5. Check Engine (has been on since my car touched 70,000 miles)

I have taken my car to a Mercedes specialist here and he told me to replace the front brake pads ... i did. AND all the lights are still on. He then suggested that the main power line in the car needs to be replaced ... which will cost me $800 !!! I dont think that is the problem though ... and even he will not guarantee that replacing the wire would surely get rid of all the warning lights.

Only thing i changed about 7 months ago was to upgrade my rims to Lorinzer rims. I have slightly bigger tires on the back. But these are 17 size original Lorinser rims !!! All the warning lights came on about 2 months ago. So i doubt the rim size or the tire size have anything to do with the warning lights either.

When the lights started turning on .... i would pull over and turn off the car for like 20 second and restart the car. All the lights would not come back (except for the check engine light). And then slowly the lights started turning on more frequently. And now the lights surely come on as soon as i put the car in Reverse or Drive ... within 5 seconds.

I had added power steering fluid ... which i purchased from Auto Zone. Maybe that has something to do with it. It was the right one ... but obviously not purchased from the dealer.

PLEASE HELP. I am so sick of these warning lights that i feel like getting rid of my car and going back to a Lexus !!!

I have not taken my car to the Mercedes dealership because i think they would charge wayyyy too much to pin point the problem and then they dont guarantee that the work they will be doing is going to correct all the problems. Any suggestions ? I mean ... how much do you think they would charge ? In Houston, Texas ?


THANKS A LOT.

...extremely easy repair.

Check the condition of the voltage regulator brushes.

Could this be it?

Of course !!!!

ASR has 4 wheel speed sensors..so, guess what. You need 4 same size tires , ASR systems will even trip codes if the air pressure is unequal...

A couple of guys have told me that ... but the thing is that i replaced the rims and tires almost 8 months ago. And all this started about 2 months back. So if the problem was the rims or tires .... should the warning lights have come on after i installed them ?

You think it can be some sensors ?
Because the warning lights come on ... one after the other ... as soon as i start driving it. Like within 5 seconds !!!

Thanks for all your help guys.

Why don't you just go get the codes instead of having us mention things it could be..??????

How do i do that ?
I have a Pioneer AVIC-N1 Navigation System in there. And it also gives the voltage which stays at about 13.4 v


Thanks

You're good

That was one of the first thing i was suggested to do. I replaced it and it didnt make any difference

Thanks though.

Suddenly having the same issue on my 1997 E320. In the past it was related to a low-voltage condition. I resolved by cleaning the corroded ground cable in the battery compartment.

This time it's different because I can shut the car off and start it right back up and the light goes out (before, the car wouldn't turn over due to low battery).

Question - can replacing the brake switch help on my car? I see only the 98-03 cars referenced in post 17 above.
