Performance of my V50 (2009, 1.6 Diesel 100,000 miles) is awful on steep hills. I'm wondering whether I have an intercooler system leak, that only manifests itself under high load conditions.
I've recently done the following work:
All glowplugs replaced
Fuel filter replaced
DPF pressure sensor and hoses replaced (inlet hose had failed!). Regens done since.
MAF sensor replaced
EGR valve replaced and calibrated
CEM contacts cleaned
Turbo pressure converter/controller replaced
Car starts fine, idle is steady, engine revs to over 3000rpm, no smoke, no fault codes since doing the above work.

I started getting "1507 Turbo Control Low" code. Turbo boost pressure was only reaching 1,400HPa, compared with desired pressure of 2,100HPa.Just replaced turbo (new Garrett GT1544V), intercooler hoses and flushed the intercooler. Fault code cleared and performance restored. Turns out all the vanes in the turbocharger had disintegrated!
