For the 2nd time in as many weeks, my car did not move when put into Drive or Reverse.
Revs, but no movement.

When I started her, I did get an ESP warning, a runflat indicator inoperative and a Service Brake visit Workshop warning.

Put her off for 2 minutes, started again, and all was well.

I did do about 75 miles of driving in heavy traffic today and to think of it, the other time it happened, the car was used extensively.

No jerkiness, no bumps, thuds, just creamy smooth changes...
what could this possibly be?
I have read through many, many threads, but nothing definitive or conclusive...there..

Same problem today, but not moving after restart...anyone please...?

Definitive diagnose pull code with MB DAS. To start, check electrical plug to ECM if fine, “may” be input/internal speed sensor in which case TCM needs replacement.

Thank you so much, Konigstiger!
Hopefully will get a printout of what they find, today.

Nothing. They could not find anything wrong with it.
Not a single code thrown or stored. How simply bewildering...

I'm worried now, because she's just become unreliable.
