engine management light comes on, any help welcome

[dcj78]

I've had the engine management light come on my 2005, B170. I had a diagnostic report done and 3 codes back. 00F8-8, 00F6-4 & 00F6-8. After getting the codes it then states check values for components B28 and M16/6 in idle and under medium load. Any further advice on what this fault actually could be would be well received to inform me prior to going to my local garage.

Those codes arent recognisable at all. Was the check done on STAR? If not I would suggest getting it to a garage that has one.
