EML W211 320cdi

[Dazzler]

I went to overtake today. Whilst lots of throttle the power cut and eml came on which I guess is limp mode. Pulled over and switched off. Started again and have some power back but eml still on. Can't get on a star unit till Friday.
Might be coincidence but car had a service 2 days ago?
