central South Dakota | Code is 128S248, data link erratic. Polished grounds. Diesel diagnostic laptop scanner showed excessive oil pressure, truck has been parked for weeks. Replaced oil pressure sensor at the base of the oil filter housing, nothing. Still reads excessive oil pressure. I look forward to suggestions to get the truck back in service. ECU and transmission harness replaced 1 1/2 years ago. Mercedes engine.
