Hi. c180 2012 on startup has multiple failures>traction,engine light,airbag etc etc...i turn the electronics on and off numerous times>5-20 times and it then will start. As soon as the radio goes on I know the car will start fine. If i start it when all the error lights are on the engine sounds terrible and you cant drive the car.
I got it serviced and they cleared all the codes etc but said they couldnt find a problem...
The car was left for about 17 hrs and the problem came back. The problem is around when the car is left for a period of time before starting -10-24hrs.
HELP!!!
What is going on?
I just spent $1000 on a service and the main issue was not fixed

 

I have exactly the same problem, did you manage to find out what the problem was, can you please advise
