#1: 1.4 HDI fault....the last thing i need this year! Author: Royster, Location: belfastPosted: Wed Dec 28, 2011 4:18 am ---- first off i'm sorry i haven't been around much this year, i found out in jan i might have epilipsy and i'm not aloud to driveso thats my 206 parked up along with all my bikes and my wife has been driving us around in her 206, this is the one with the fault....
it's been on and off for some time now, it only ever did it for a few seconds but this time it's stopped the car completely.
it's a 1.4 HDI, and the fault is a juddering like the car has cut out for a second, then it's fine again for a few more, then it judders again and normally it clears and the car drives fine ,the engine light comes on but goes out the next time the ignition gets turned on.
but on boxing day on the way to my fathers for xmas dinner it started again, went through the "normal" cycle of juddering and clearing but this time the wife pulled in and the car cut out. i asked her to turn off the ignition and wait, once we turned it on again it was fine but 30 seconds later the same again and it cut out.
we waited about 20 mins for her brother ( a mechanic) to call over to us and he followed us home again were the car drove fine of 10 minutes but bigan juddering the last few feet.
speaking with him he thinks it's fuel related, like the tank pump or maybe something like the throttle sensor but the fact it wouldn't idle makes him think the pump.
now looking on her i've found everything from, injectors, bottom pulleys,seals but no mention of pumps or throttle sensors so what would you guys suggest i say for him to look at first ?
he's going to think i'm trying to teach him to suck eggs but with me being off the road and her 7.5 months pregnant and already having a 2 year old the car is a necessity ......so any help is much appreciated guys.

Diagnostic light has come = there will be a fault code stored in the memory.
Read the fault codes, they will give you a good idea what to look at.

ok i didnt know that. thanks for clearing that up
#7: Re: 1.4 HDI fault....the last thing i need this year! Author: Royster, Location: belfastPosted: Wed Dec 28, 2011 5:37 am ---- He is going to get it plugged in when the garage opens up again but ill tell him about the egr valve and if it's not that at least hell clean it and it'll be one less thing to go wrong
I'll keep you all posted.
#8: Re: 1.4 HDI fault....the last thing i need this year! Author: Walberino, Location: BuckinghamPosted: Fri Dec 30, 2011 10:18 am ---- Royster any news on this mate? My car is doing exactly the same thing. It's a 2003 1.4HDi and has been fine for the 18 months i've had it until recently when it did the 'judder' thing and then cut out a few seconds later. I carried on to work and then drove home and it started juddering and then cutting out every few mins to the point that it is now undriveable. I have taken a lot of the parts off and given them a clean. Got the EGR valve off but i can't see where to clean it as it is all enclosed in a metal casing.
Oh, and the engine management light is on, but I have had the codes read and there are no codes stored...helpful.
Let me know if your trip to the garage brings up anything. Cheers.

There will be codes if you use the correct tool to scan it
#10: Re: 1.4 HDI fault....the last thing i need this year! Author: Walberino, Location: BuckinghamPosted: Fri Dec 30, 2011 11:09 am ---- Oh yes? I guess I will have to take it to an official Pug garage then and get them to scan it. Thanks for the info

#12: Re: 1.4 HDI fault....the last thing i need this year! Author: Walberino, Location: BuckinghamPosted: Fri Dec 30, 2011 1:35 pm ---- I have heard that unplugging the EGR would cause you to get worse MPG and reduce the life of the Turbo and CAT...not sure if this is true though?
#13: Re: 1.4 HDI fault....the last thing i need this year! Author: ma.langan, Location: Leyland, LancashirePosted: Fri Dec 30, 2011 2:50 pm ---- All it does is shove exhaust gasses back into the engine? Cleaner engine is my thought, ay well be reet
#14: Re: 1.4 HDI fault....the last thing i need this year! Author: propaintballa, Location: Weymouth/Leamington SpaPosted: Fri Dec 30, 2011 3:23 pm ---- As of today, my 2L HDI is doing the same thing… One minute it will be fine, the next it just wont pull, judders and then pulls fine… No EML though…
I'm thinking it's injector related as it was run out of fuel about a week ago (But it has been normal until now :/)
And my injectors tick quite loudly…

Correct.

Author: Abzynthe, Posted: Fri Dec 30, 2011 4:28 pm ---- Id dont know if its the same, but on a 1.4 petrol, it was doing similar and the fault was the temp sensors on the inlet manifold and somewhere else werent communicating properly causing the engine to run rich?
#17: Re: 1.4 HDI fault....the last thing i need this year! Author: ma.langan, Location: Leyland, LancashirePosted: Fri Dec 30, 2011 5:12 pm ---- Why does it reduce life of turbo though?

I really don't think it does. I've read A LOT about EGR's and i've not heard anyone come up with that before :/
But can we try and help us poor people that have broken cars! When i last took my car out this evening, it was fine, so i have no idea what's going on :/
#19: Re: 1.4 HDI fault....the last thing i need this year! Author: Walberino, Location: BuckinghamPosted: Fri Dec 30, 2011 6:02 pm ---- Apparently the recirculation of the exhaust gasses through the engine create lower combustion temperatures, therefore if you block the EGR from recirculating the gasses the combustion temperatures will be higher and therefore the turbo will operate at a higher temperature and fail quicker due to the constant high operating temperature.

So how did you fix this? Just change both of the sensors??

Pretty sure that having slightly cooled exhaust gas passing through the cold side of the turbo would be more detrimental to your turbo/performance than having slightly higher temps on the hot side…
The way i see it anyway

You may well be right buddy, thats just what i've heard, i'm certainly no expert on the matter

Ahhh fair enough!
Either way, I don't think this is an EGR fault, however, i'll unplug mine tomorrow and see if it makes a difference!

I would have thought something like water wet or whatever its called would compensate for the higher temperature. Worth it for the extra power if the mileage is not too high.

Correct
At last, someone who understands one of the functions of the EGR valve on a turbo diesel
#27: Re: 1.4 HDI fault....the last thing i need this year! Author: Royster, Location: belfastPosted: Sun Jan 01, 2012 5:57 am ---- Hi guys,
So the brother in law took the car and changed the fuel filter which was completely full of sludge, said he took it out for a run and everything was fine.... Until the 33 mile when it did the same thing and stranded him .
I'll tell him about the sensors and see what he says.
Cheers so far guys.
#28: Re: 1.4 HDI fault....the last thing i need this year! Author: Royster, Location: belfastPosted: Sun Jan 01, 2012 6:04 am ---- I just reread propaintbellas post about the injectors ticking, Claire's car was doing the same when she started it on boxing day.
Could I have injector/sensor fault ?

I can only really hear mine when it's under load, between like 1.5 and 3k rpm…
#30: Re: 1.4 HDI fault....the last thing i need this year! Author: cosmicdance, Location: Leeds, UKPosted: Thu Jan 05, 2012 11:58 am ---- |I also have a 1.4 HDI and it was cutting out similar to yours.
It turned out to be the crankshaft sensor and once I got that replaced, which was very cheap, it has been fine ever since.

Author: Royster, Location: belfastPosted: Fri Mar 02, 2012 4:28 pm ---- just got the car back last week and it turns out cosmicdance is completely right, crank shaft sensor ......... the little b*****d !! car drives 100% and pulls better from low revs due to the fuel filter being replaced also.
thanks for all the help guys and i hope this helps someone else along the lines.

That's interesting…
My car hasn't done what yours was doing since it first did it… But i'm wondering if changing this sensor would be of any benefit at all just to make sure :/
My rev counter has stopped working, not sure if that has anything to do with that sensor
