Peculiar loss of power

[Veg]

How's this for a picky CLS. Travelling to and from Cornwall for the Christmas break. Power loss (will get it checked on STAR) on the A30 yet fine on the M5 -either way! Doesn't like being 110 miles from home?!?!
My OBD says lamda sensor.....

Is it in limp-home-mode and does it reset by switching the car off / on ?

My CLS did the same , the first time it was diagnosed with a faulty Lambda sensor which was replaced. The second and third time it did it the EML came on and the Mobilo chap booked it into the dealers for another look and they found a faulty inlet pressure sensor which was replaced and the EML reset and it has been fine ever since.

Come to think of it it was reset by turning the ignition on and off. No EML ......
