#17: Re: Very sluggish 1.4 HDI Author: V1nn13, Posted: Wed Apr 23, 2014 3:24 pm ---- Neither the engine light or any of the other lights have come back again, but problem still persists.
Can't see any sensors post-cat, or along the whole of the exhaust system for that matter. Might be wrong though and there may be one hidden away i've missed Thought they had a lambda sensor or something of the sort?
It's just strange that no one I've spoke to, even people who have been in the business for years, know what the problem is :/
Short of taking it to a Peugeot garage and spending best part of a months wage on getting the problem diagnosed, I'm stuck on ideas
#18: Re: Very sluggish 1.4 HDI Author: rlees85, Location: DaventryPosted: Wed Apr 23, 2014 4:00 pm ---- Ah.. no DPF on the 1.4's... Sounds like OP done a de-CAT then
I know nothing of the 1.4 HDI so this will be my last post - but if it has electrovalves and vacuum hoses to control the EGR valve/turbo VNT I would investigate that next. Make sure there is no vacuum leak anywhere.
It could also be the electrovalves themselves. For example, the EGR electovalve will have two little rubber hoses coming from it. One goes to the egr valve itself, the other to the vacuum source. If you remove the rubber hose going to the vacuum source and put a suitably sized bolt in the hose, this will rule out an issue with the EGR electrovalve.
You can test the electrovalves that control the air dosers (if present) in the same way.
If the turbo is controlled by one too it might be worth just replacing the electrovalve controlling the turbo as you can't really test this one. Never a bad thing to change anyway and should cost around £40.
#19: Re: Very sluggish 1.4 HDI Author: kirk46, Posted: Wed Apr 23, 2014 4:08 pm ---- the turbo on these are controlled by an actuator, not sure about the newer models?
#20: Re: Very sluggish 1.4 HDI Author: V1nn13, Posted: Wed Apr 23, 2014 4:28 pm ---- Yup manual actuator on mine. Haven't fiddled with it, do these often wonder?
I shall have a look at the vacuum hoses tomorrow
Thanks for the suggestions, last few weeks have involved me staring blankly into the engine bay and scratching my head trying to figure it out
When it comes to this new fangled FI with it's ECU and many sensors, I can't figure things out
Cheers
#21: Re: Very sluggish 1.4 HDI Author: V1nn13, Posted: Thu Apr 24, 2014 4:19 pm ---- Another quick update,
Removed and blocked the vacuum line that goes into the EGR electro valve (comes from the brake servo?) and seems to run spot on, will give it a test run to work tomorrow, but pretty sure that's cured it
Does this mean my EGR valve is screwed or the electrovalve? Have checked for leaks along the lines and can't find any.
Cheers
#22: Re: Very sluggish 1.4 HDI Author: rlees85, Location: DaventryPosted: Thu Apr 24, 2014 5:16 pm ---- Hope its still ok tomorrow! About which one is faulty...
Easy way to test:
Reconnect vacuum pipe to electrovalve and disconnect the (blue?) electrical plug going into the electrovalve and then:
Still fixed: EGR valve is faulty
Goes back to being pants: EGR electrovalve is faulty
#23: Re: Very sluggish 1.4 HDI Author: V1nn13, Posted: Sat Apr 26, 2014 10:45 pm ---- Ahh, that'll be a bum electrovalve then
Lovely to have the car back again, and thanks for all the help. All I got from the local lot was the usual...'the problem is the Peugeot badge on the front' :/
Just a quick one (on an unrelated subject),
Is there an easy way to pinpoint the culprit for my whine is coming from?
Sounds like it's coming from the aux belt area, but short of changing each pulley until it stops, I wouldn't have a clue on where to start.
Usually I would use a makeshift stethoscope to pinpoint noises, but for obvious reasons I've decided against this approach :S
