But I agree, remove the sensors and clean them off, that would be my first step as it's incredibly easy and should be done as regular maintenance.

Thank you for your pleasant reply. (Some here are not so, you know!) I have had my share of those issues also, but mostly resolved - for the moment.

I'm so glad it's not just me then! I marvel at the CIS as a concept and curse at it as an application. My SL has been an 18 year long story of "fix one thing, two more break"! This past month was the first time in ownership that it's gone through 2 consecutive tanks of fuel without having to be parked for something going wrong and I hope it decides to stay that way for a while! I certainly don't mind working on it, but good lord, it's sure nice to drive it without worrying about the "next fault".

Seriously though, these older Mercedes vehicles were marvels of engineering when they were built (they still are), but 20-30 year old technology breaks down from age, use, and neglect and requires service. The more electronic gadgets you have, the more likely they are to have issues later in life. It's just part of owning an older car, if you aren't willing to work on it from time to time, pick something newer and Japanese. Or if you're a glutton for punishment and really love electrical infidelity, buy a Ford from the 80s or 90s! Talk about drive you to drinking...

I wonder if any car that was built, lets say 2010 and after, will last as long as these older MBZ.....built in a time when overhead cost was your least concern. I purchased my 201 in 2005 with 174k as a daily driver, it now has 401k. Since then, pretty much everyone that I am in contact with has been through at least 3 cars, some 5, a piece.

:: UPDATE:: For those who care, I have taken out the front ABS sensors and done a thorough cleaning - which I must say, was much needed! Unfortunately it did not solve this ABS light problem. The cable leading from the passenger side brake up into the fender well was in good condition, however the drivers side is really cracked and quite 'crumbly' looking. The insulation that is. When I did an ohms test on the drivers side sensor I get a .000 reading. Am I to assume this is good? Also, how would I go about testing the 6-pin relay under the black plastic pump cover? Thank you.

Your driver side is toast. A quick check of the passenger side would confirm that. What's the part number on it?

Peach parts shows it to be 124-540-16-17. I would say that's the MB part # yes?

What would you want for the sensor?

Well, don't know what one has to do with there other, but I replaced a burned out third brake light bulb yesterday and the ABS light has stopped coming on when applying the brakes! Both the kids have been out in it since the bulb replacement and both report that the ABS light has not come on. I'll take it

:::ARRRGGH:::

This car sure knows how to keep me humble! So it's been almost 2 weeks since I've seen the ABS light and just yesterday I had to drive it. I turned on the headlights and THERE IT WAS, the ABS light aglow! I turned OFF the headlights and the ABS light went off immediately. I actually did this several times and each time the result was exact. What on this green planet might be causing this

Thanks for your ideas...

Anybody???

I can't imagine what the headlights have to do with the ABS system to trigger a warning light. The headlights do load the alternator pretty heavily, is it possible that when the lights turn on, the voltage dips in the system too far? Barring that, you may have a wiring fault somewhere behind the dash or in the fuse box (just chased the latter down in the turn signals in my SDL, wasn't fun).

That's a possibility I suppose. I'll take a reading on my multimeter to see how much it does drop with the lights "on". Dear Lord, I do hope it's not a wiring fault!
