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.
