No boost...driving like a slug

[lorry33]

Hi all,

My V50 2.0D 2005 is losing its kick, going up hill I'm dropping RPM's averaging between 1500 2000 and no boost . As soon as the road levels out I get the kick from the turbo and all seems normal. It generally struggles at the slightest incline and seems to take an age to get the turbo to kick in on a flat even road.

Checked the vacume pipes from the boost solenoid on the side of engine and the hose which goes under the engine(from the solenoid) was a little gunked up. I cannot see exactly where its connected to as its a right pain to get to, it seems to go under the 2nd boost solenoid which is located down below the fuel filter and alternator is.

I also found a little split in the plastic pipe from the air filter going to the back of the engine(looks a pain to replace) i have temp fixed this but would need replacing.

I ran my OBD2 scanner and it brings up these errors.

C302 -
P0047 TURBO/SUPER CHARGER BOOST CONTROL SOLENOID CIRCUIT LOW
P2263 TURBO/SUPER CHARGER BOOST SYSTEM PERFORMANCE

Hope all this makes sense

Regards
Laurie
