    The same error was displayed in the fire Man TGM 15-290. The new car has done 900 km. Which relay is it?

    1. Are you turning off the main battery breaker if there is one?
    2. If so, how long after ignition off?

    The main switch is on. It has two options, the first is a short press that turns off the electricity after 180 minutes, and the second is a longer press that turns off the electricity immediately. Colleagues were on a trip and probably the driver turned off the electricity too soon after that trip, which could be the cause of the error, right? When I started the car, the check engine light came on red and after driving, the power was reduced.

    Most likely, this was the reason, the rule is that after turning off the ignition, wait about 2 minutes for the so-called run-down in the controllers, in other words, the correct completion of the system operation.

    This surprises me a bit. Does this TGM already have the new Bosch adblue system with an injector on the muffler?
    After all, this is a new vehicle and it has a warranty, and if the fault persists, you should drive to the service center.

    Car from 2019. I visited the service, they deleted the errors (there were a lot, in all groups) after the company where the bodywork was made, and everything is fine. Time will tell if this is due to the power being turned off too early. Thank you for your interest.
