The engine light comes on on my 2007 R350. My mechanic read the code and said there were 22 different and unrelated codes that came up at the same time. The codes were reset. I drove a while and the same thing happened again. Is this some type of electrical problem? Loose connections? Please help!!

 

If your engine light came on and threw 22 codes, there is obviously some sort of issue going on - what was the mechanic's solution for this? There are sets of codes that have to relate to each other or else your check engine light wouldn't be on.
