We had the pleasure of tuning this Mercedes E63 today.
came to us initially in December, whilst carrying out stock power runs, the car ends up in limp mode & misfiring on cylinder 7 which had happened to the customer in the past.
After health checks and a look over couldnt find the cause.
Back today for our GAD stage 2 software after the issue was resolved.
Ended up being a loose relay connection on the ECU!!
