Your long battle with the abs light may have been resolved within 30 mins - 1 hr of actual physical work on your end. If a glowing ABS light frustrates you to the point where you've made the decision to never own another MB again, I'd hate to see you having a rough idle/hard start issue

. If it turns out one of your sensors is toast, I may have an extra that I could send you (front sensor only).

Ohh gosh, rough idle and hard start issues are what define my hatred of CIS, only had my engine running 100% correctly for 3 weeks before something else failed and the system went haywire.

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.
