SL/R129: Coolant level question/problem
The main problem is with the dash indicator. When driving on local/street roads, the indicator light does not show up, however, when driving on the freeway, the indicator light turns on (stays only for most of the travel, sometimes turning off then turning back on). Only once in awhile does the indicator come on during street road driving as well as not being on during freeway driving.
I would add more coolant but I fear overfilling it, if that could happen. The indicator light doesn't worry me much most of the time, but it does become annoying when it shows up when I happen to be on the freeway, especially at night.

The dealer dude at the rapid service lane said it was the oil level sensor. $500+
Not being one to believe the first thing that I hear I decided to drive over to my friendly local repair shop. German Benz trained guy, and a bright kid assistant. When I asked them the kid piped up and said that there was a bulletin.
They looked it up and it said something about reloading the console computer program.
I'll find out Monday if it works.
Best Regards,
Barry
