Anyone have issues with EC tune after MB Software recalls?
Hi guys~
Took my C63 into the Benz dealer "only" because I was showing it had two recalls:
1. Update engine control software
2. Update AMG suspension control unit
Well, I have a EC stage 1 tune I have been running and I switched it back to the stock map before taking it in. I get the car home after the updates and try to put my tune back on and get a "Code COx2101 file incompatible with the ecu". NOT GOOD. I've already sent a pic of this to the support guy Sean so I'm sure when they get in this morning hopefully they will have a solution but I was wondering if anyone else has done these recall updates and suffered a similar fate? I've had updates on previous AMG cars and never had this issue before as long as I went back to stock before the dealer got their hands on it.
Hope MB isn't locking the ecu's down like Toyota did on the Supra's after that first model year.

Same happened to me except I was told updates wouldn't change anything. Never trusting updates again or taking the car in for any software recalls. I heard through the grapevine the whole debacle was a silent fix because PFL cars didn't meet emission targets. Anyway can't be reversed or so I've been told.

My cold starts were fine before and after updates. Updates just made the car quieter (overall and also the pops and bangs which no longer snap) and neutered sport plus mode
