I just had my S54 in for service because of the EML light and the SES light. I had not driven the car for a few weeks and took it out last weekend for a 15 minute ride. Ten minutes in, the EML light came on and after gassing up the SES light came on.
I also have Dinan software installed.
The lights were on and off for a couple of days this week and I took it to the dealer yesterday. The lights were not on at all yesterday and the dealer found NOTHING.
They told me that if it happened again, I should bring it right in with the light on. (Of course, that's what I wanted to do on Monday, when the pricks told me they could not see the car until Thursday)
Let me know how you make out and I'll do the same.
