Hello,

I have a problem with a Linde L12 - 379.
Everytime you start the truck an drive forward, the machine will operat normal. But if you want to drive back, it could happen that machine won`t drive. But only sometimes, it also could be that the truck works normal.

I have seen the Error 31 with Truck Doctor. I Changed the potentiomter (only the poti, not the hole unit) but it isn´t better. Sometimes it works, sometimes not.

Somebody any ideas?

Thanks a lot. Tom
