Hello guys, I have here a curious error which no one has found so far, therefore I turn to the professionals here in the forum. Vehicle MAN TGL 12.250 Euro 5 EEV First registration 01/13 The driver has already reported several times that he is suddenly slowed down during the ride on the highway or even the engine runs out briefly. The cruise control switches off immediately. Sometimes at this moment the ESP warning light turns on in yellow. Ignition remains switched on, Tacho also shows no voltage interruption or ignition from signal. It could also be that it is not the engine, the moment is so short that you can not determine it the driver thinks. We have been to MAN several times, as this is a guarantee, besides the Fzg. has a Comfort-Super maintenance contract (full service). No one has found the error so far. We have now closed it to our workshop tester and read the following errors, which cannot be deleted. CAN Bus: Raddre hzahlsensor VA Signal implausible. However, if I measure the sensors directly in a standstill and during the ride I have normal measured values. I am curious if someone had this error before or the MAN professionals have an idea. The driver of course always asks me what it could be. Thanks for your answers.
