After slipping into limp mode yesterday I took the van to a mate with a code reader , it came up as EGR valve stuck open , he reset the ECU and I was on my way again , a little lumpy but good enough to get home .
EGR is about £100 so not all bad , however , what a ball ache to get it out , then I saw this Wynns cleaner for a tenner in Halfords and thought it worth a punt.
Just do short sprays into the open turbo until can empty with a warm engine idling, not much happened but did get a couple of puffs of black out the arse end .
Then directed to go for a drive at no more than 3000 revs , still not much happened, then whilst accelerating away on a rather busy roundabout BOOM
This massive cloud of thick black smoke went everywhere, those poor people behind me
It’s seems to be running A1 now , time will tell as the ECU will not have had enough miles to register another fault quite yet , here’s hoping
