Just bought the van but engine manage management light on but mechanic cant find the problem the van when driven goes into limp mode he reckons its a censor problem or electrical he said there has been lose wiring and 1 wire he cannot locate where it goes, would it not be a case of starting from scratch with the wiring i,m thinking it must be fixable
Running Rough, Starting & Power Loss
Everything is fixable.
First thing is get it scanned and the with the correct fault code there's a better shot at a repair.
Without a specific "P" code were in the dark here.
Try some body with Vaux diagnostics as it's more accurate.
