I went to start our motorhome this morning and there was a whining noise coming from the fuel pump. I plugged in MultiECUscan to see if any errors had been logged. There weren't any so we decided to continue with our journey. Anyway, after 20 minutes or so we received a P0089-78 error and the vehicle went into limp mode. We managed to get ourselves to a garage that thought the issue was a blocked fuel filter so they changed the fuel filter. We continued on and within 5 minutes the same P0089 error occurred. When we clear the error and try to limp on we get a few 100 meters down the road before the error re-occurs.
Does anyone have any ideas as to what could be the cause?
