Over the last 4 months my S420 has 3 times "set off" the ASR light while turning. Both L and R turns have triggered the light. Each time going into limp home mode, but would return to normal after a re-start.

What might be causing this--- where should I start looking? At this point it's just an inconvience since it has re-set OK each time . This last time, yesterday, it had not re-occured for several thousand miles. Every time it was at slower speeds while turning (2 lane intersection - 90 degree turn) at possibly 20-25 mph. Not the same intersection and no slippery stuff on the pavement that I saw. And I was not driving aggressively enough to cause tire slippage I don't think. Tire pressures are equal at about 32 lbs. Same brand Mich tires, no tire wear problems, abt. 30 thousand miles on tires.

any thoughts appreciated.

good place to look is the wheel sensors and cables.

I had a similar problem, however, it only happened when turning 90 degrees left between 25-35 mph. I replaced the right side cable which resolved the issue.
