Struggling with a focus 1600 tdci peugeot engine i believe. Came in the other day the red cog light on dash comes on and car looses power. Switch it off start it up again and car runs fine until light comes on again, usually when engine is under load. plugged it in and 2 codes in it one for EGR valve and one for over boost. Cleared them gave it a good long run and light came on, checked the codes and both came back so fitted new EGR valve and new boost pressure sensor. Gave it another run and light came on plugged it in and only turbo over boost code present. We checked for any air leaks with smoke pro and found a leaking pipe seal so fixed that, also checked the waste gate is working and it seems to be OK. Tried it again and fault is still there!! if anyone has any ideas they would be appreciated thanks Andy..
