#1: 1.4 HDI power loss Author: D4VE, Location: BradfordPosted: Sun Dec 12, 2010 9:18 am ---- Hi,
I have just bought a 1.4 HDI but is really slow. You can hear the turbo spooling but still down on power.
Any ideas?
Dave

Feels to hit a flat spot at about 2500 - 3000 revs

vacum pipe can cause this ??
#11: Re: 1.4 HDI power loss Author: D4VE, Location: BradfordPosted: Mon Dec 13, 2010 4:18 pm ---- I checked the air intake pipe and the was a joint loose so sorted that but will check the vaccum pipe tomorrow

Just an update on the power loss problems. The code it brought up apparently relates to a blocked exhaust, more likely to be a collapsed catalyst.
Will be taking it off one evening this week to attack it! One its all cleared out I should be back up and running!
I'll keep you posted.

(dont attempt to clean it with anything else!)

Thanks panason1c, they did confirm the fault code for the maf was showing but a new sensor has been fitted, hovever, the fault code not cleared. Once cleared the only fault code it brought back up was the one that lead them to the exhaust again.
Thanks again though, i'll try it if this doesn't work.

It does sound more likely to be a blocked cat then, just knock out the innards, a cat is not an mot test item on a diesel so dont worry about that and the car should be a bit more lively without it.
