Can anyone help with this fault code

No idea, I'd suggest describing the problem/symtpoms and perhaps having a scan done with Star or a Mercedes specific scanner.

Engine management light came on along with abs light tyre flat light and i think ebs light also revs went up to between 3000 and 4000. I also noticed could not get reverse gear (automatic) until I switched engine off and restarted it .

With that many things check the battery or batteries are good.

Other than that a real scan is what is needed.

Cool thanks. I had it reset to see if it was just water from weather related

Your $7E8 and the $7E9 are fuel/ air intake codes.
