The turbos on these are variable vane so it is possible the vanes are sticking and causing the overboost.
I have just come back from talking to the mechanic and he believes it is this. There are two spindles inside (I think he said they are nested inside each other but maybe I misunderstood?) and he thinks they have seized and as a result it appears to the ECU that it is over-boosting, and as a result gets flipped into limp mode. If you drive steadily it's fine; he had it charging along at 70 miles an hour without any problems.The turbos on these are variable vane so it is possible the vanes are sticking and causing the overboost.
EDIT Great link! Hopefully this or something like it is what my mechanic's choice of firm will be doing with the turbo once they get their hands on it.More info on sticky vanes here: http://oilybits.blogspot.co.uk/2014/02/fauly-code-p00046-turbo-boost-control.html
I do intend to clean the EGR. Longer term, wondering if it's worth fitting a PCV catch can...
Good morning everybody, just an update on the situation here.The turbos on these are variable vane so it is possible the vanes are sticking and causing the overboost.
As soon as I can remortgage the house I will look into getting some BFG All Terrain T/A KO2...Glad it's sorted (good spot by silvercruiser !). No experience of Runways, but Tyreleaders have BFG and Coopers. Not so cheap since the £ dropped, but still worth a look.
Also had runway enduro on my first 80 fir about 50k miles, they were really good in all conditions. Had notchy steering too which needed newpump and pipes to fix it. Had a £1500 bill at toyota huntingdon for that!!As soon as I can remortgage the house I will look into getting some BFG All Terrain T/A KO2...
What do you use for reference when doing something like that? A Haynes manual?Refurb of your own pump is a morning's work and a seal kit and probably a bit of oil resistant hose is less than £30.
