This started out to be simple, cheap and, most of all, practical!

With all respect, zafar's solution is just the opposite! ABS sensors??? Mounting gauges on the 'A' pillar?? Not easily done, not cheap and not practical for the average MB owner. Nuff said.

Also the low coolant scenario has a problem: in my car it's possible to have the CTS (B10/8) with no coolant flow but the coolant low sensor be ok! It's about 6" below the CTS and there could be coolant in the overflow reservoir.

This would give you a low(er) temperature reading but could still do damage to the engine because of low coolant but not enough to give an alarm.

Willy, how many people would want to take their IC out so they can drill some holes for mounting LEDs??? And even if they do, how many could actually do that and wire LEDs (what the hell are those?) to my fan sensor ckt?? How about "NONE"!
