Our 07 diesel 4WD w/169k miles is constantly going in to limp mode when
towing a 5th wheel. Have had -2- fuel filters changed by local dealership in the
last month. Both times the filter showed 0% within 300 miles of use. Dealership
can't seem to diagnose the problem. It has become a serious safety issue. Any
suggestions or experience out there with this problem??
Have you read any error codes from the OBDII port with a scanner? That is the first step that I would do to try to identify the problem. Otherwise, the list of problem sources could be extensive. OBDII scanners are cheap now a days too. Mine cost me only $29.00, If you can reproduce the problem, have the scanner connected to the port ready to read error codes. (Hope this is helpful.)
