The engine management light comes on intermittently - one journey on; one journey off. MB diagnostic test is inconclusive. (HJ suggested using Shell V Power which I will try) Anyone got any other ideas or remedies. Thanks

No fault came up on the diagnosis screen. After resetting the light went out for 3 days then reappeared! :-(

If the Mil light is on ,then there must be some error stored in the event memory.What equipment was used to check the system?

My helpful, local Independent MB garage plugged in a diagnostic laptop. No fault was logged. HJ suggested, as a first step, I fill up with Shell V Power fuel. I drove till nearly empty and filled with the Shell fuel. The EML went out and has stayed out. Does this say something about supermarket fuels? Thanks HJ.
