Dealer ECU Update
Anyone MB experts know if this service line means that the engine ECU software was updated?
Its a long story but my Velos tuned car had a breakdown and without options ended up at a Mercedes dealer. They repaired my car but this service line is noted.
Actually it feels like the tune was not changed.
Thoughts?
Side note, I would think that with a decent tune it would be very obvious whether it was active or not.
Not sure how you wouldn’t be able to tell if you lost the tune? I can’t even keep the car straight with all the torque down low with a tune. Feels night and day.
If you have the handheld, you should be able to check what file you’re running, and re-flash the tune if needed.
