Default 2.0 HDI 8v - 110hp model - More like 50hp :(

Just got a expert 05 plate fitted with the 8v hdi lump and iv owned one before and this is diabolical..

Its flat as a fart.
No acceleration, turbo kicks in and pulls guessing between 3000rpm and 4000rpm and gives up..

No smoke no noises, idles fine..

Unplugged EGR and no difference..

its as if im driving only using a quarter of the throttle if that makes sense

Can anyone help

Im guessing so, as i unplugged maf and it made no difference, would explain why it goes better with less pressure on the throttle..

Going to cut it out for now

But then again if unplugging the mad made no difference would that suggest it's just not working at all??

Check all vac hoses for splits if none found drop servo hose off of vacuum pump and squirt a bit of oil/wd40/silicone spray into vac pump reconnect servo hose and see what happens.

I had one which for months would intermittently be flat to about 2750 then take off like a rocket non return valve in vac pump was the fault but took best part of a month to trace

Thing is it don't take off like a rocket either no matter how hard I rev it..
Also which is the vac pump to spray down so many pipes :/
