I had a tune installed on my Sprinter to increase horsepower and torque only back in Feb. 2021. I now think the tune is causing a conflict within the Sprinter computer system. I decided to pick up the motor home tomorrow and take the ECU out to have the shop that installed the tune remove it and install the factory settings. The MB tech felt the tune was causing a conflict within the system. Hopefully the system will revert back with no further issues(fault codes and limp mode). The shop that installed the tune said they can remove it and place the factory settings back into place.
