Need help...warning lights...
OK - just had RENNtech ECU and Pulley done a week or so ago at MB Sarasota. Tech, who I trust, installed and drove car and all was good. I picked up car from them on Friday 2/12.
On the next Friday (2/19) I was driving car home and while moving the Parktronic lit up and stayed on and right after that the SRS light came on and stayed on.
On Saturday (2/20) I took the car to the gym in the AM. Parktronic back to normal and SRS light off. However, I got a message that "Convenience Features Unavailable" (or something like that) and basically none of the equipment worked (radio, keyless go, trunk release etc).
After the gym - all way back to normal...
Today, I took the car out a couple of times. Beautiful day here with top down...
Anyway, I just ran out to do an errand and now the CEL is on.
Any thoughts and/or suggestions?
Thanks,
D-

Low/failing trunk battery. CEL most likely will need to be cleared w/scanner or star. (depending on fault)

Weather got cold (for FL) last night - drove home in the 40s and the same crap. The parktronic lights up - then the SRS light comes on. This morning no issue... Sounds like it is time to get a battery.

If the CEL cleared by it's self, may be a low volt code. I'd check the trunk battery and would recommend you replace it with a "manifold battery" so it will vent outside the trunk.

+1...also invest in a CTEK trickle charger (don't buy it from MB because they will rape you on price just because they branded it MB)...our AMG's are notorious for battery drainage after a few days of not driving it...
