Dave,
These symptoms were my intro to Birties. MIL light on + limp home mode. Did not happen under load though but intermittent and very annoying
to comute in limp-home mode @ 25-30 Mph. max with a queue a mile long behind you
Dr. Mike advised could be the software incompatibility between Merc and Jeep and a visit to the dealership was in order.
a free capucino + free car wash + new sofware download & £32,- later .....the rest is history as they say.
