The CC in my '02 SL500 has stopped working. I have read that this is a common problem that is often fixed by repairing cold solder joints in the cruise control module. The problem is that I cannot FIND the cruise control module. One manual said it was under the dash on drivers side, another said passengers side. I pulled panels but if it is there, it is not obvious.

Anybody have the definitive answer on where this module is located?

BTW - this is not a tire/wheel problem. Already checked.

You don't have a cruise control module. On '96 and later 500s the cruise is integrated into the Motronic ignition and fuel injection controller.

OK. I had the SL in for B service and asked about the CC. The mechanic ran some quick tests, and said he thought it was the throttle actuator to the tune of $1500. I declined to have it repaired.

I bought a used MB throttle actuator for $300 and put it on. Simple installation, but the cruise still does not work. Glad I didn't drop the $1500.

So, does this Motronic module require dealer coding for setup? Where is it located?

Thanks,
