All,

Any ideas where to start to troubleshoot this error code for 2005 G55?

I finally figured out what the issue was, it turns out there was a short on my headlights and side marker. (see attached pics) Once I resolved the wiring issue and cleared the error....the ESP/BAS error never came back even if I hit a bump on the road.

loose wire

burnt housing

I've had a weird event that happens every now and then on my 2015 G550. Every now and then my right turn signal flashes rapidly when engaged (like three times the normal speed). I get an error code on my dash (can't remember what it says, something about right indicator error). Then it goes away. Anyone ever experience that?

That's an indication that there is a fault in the circuit. Could be as simple as a bad bulb or a short somewhere in that circuit. I would start with the bulb and move on from there.
