Hi. 
I bought from an auction last year a wacker neuson wheel loader 5095, but today i got the error code: spn516420 while i was driving it on the road and it just stoped driving. The engine runs just fine, but it doesnt want to drive. I checked all the fuses, all fine. Only the error code showing.  Im from Romania and there are not so many dealears around. Please help.
