#1: Intermittent power loss Author: cosmicdance, Location: Leeds, UKPosted: Sun May 01, 2011 12:37 pm ---- Hi
I have a Peugeot 206 1.4 HDI and very occasionally it loses power.
This happens either on acceleration or a steady 70 MPH on the motorway so it's not at a certain speed.
It did it about a year ago and then stopped for around a year so I thought it was dodgy fuel.
The fuel filter, MAF sensor, air filter + accelerator pedal have all been replaced very recently so it's not them.
These were parts I replaced that had worn out as I'm not replacing parts on the off chance it's them!
I have also checked all the fuel lines and no leaks.
I haven't had it read for fault codes yet but may have to.
If anyone has any ideas I would be very grateful as it only happens every so often and sometimes I will drive 300 miles without it doing it.
Thanks
Andy

this has been covered a lot, with the 206 cutting out.
you get the picture Last edited by dopey on Sun May 01, 2011 12:59 pm; edited 1 time in total

#4: Re: Intermittent power loss Author: cosmicdance, Location: Leeds, UKPosted: Sun May 01, 2011 1:32 pm ---- Thanks for the quick replies.
I have done numerous searches before posting as often they solve problems.
However that ICV refers to a petrol engine with a throttle body housing.
Mine is 1.4 HDI with no throttle housing - the throttle is electronic, on the pedal.
Also it has no problem idling and only loses power when driving.
It feels like the fuel supply is being cut off momentarily then comes back in less than a second.
The engine management hasn't come on either.

they tends to destroy itself overtime
#6: Re: Intermittent power loss Author: cosmicdance, Location: Leeds, UKPosted: Sun May 01, 2011 2:13 pm ---- When it cut out last year I checked the device in the fuel tank, under the rear seat, but it's not a pump only a fuel gauge sensor unit with a filter on it which I cleaned.
#7: Re: Intermittent power loss Author: nashy, Location: kentPosted: Tue May 03, 2011 11:46 pm ---- have the same probably with mine did get told could be bad earth connection ????? but as yet not tryed anything to rectify it
#8: Re: Intermittent power loss Author: cosmicdance, Location: Leeds, UKPosted: Wed May 04, 2011 12:17 am ---- I took mine to an auto technician yesterday in Leeds and he couldn't find any errors that have been logged.
It needs to do it a bit more consistently before the ECU will log an error but also it clears them itself if they don't repeat after 40 cycles!
I used to love my Peugeot 205 diesel turbo, 1992, as it was so straightforward and never went wrong.
New engines are ridiculously over-complicated to comply with emissions etc.
A lot of his business is with people bringing cars in for faults on the sensors and not just Peugeots.
I might get an older one next time

I've been looking at other forums with similar HDI symptoms to ours and there are some cheap parts to replace like clutch pedal switch which I will try.

they are all intergraded into one whole unit.
#11: Re: Intermittent power loss Author: cosmicdance, Location: Leeds, UKPosted: Wed May 04, 2011 1:06 pm ---- Yes on the 1.4 HDI there is no low pressure fuel pump in the tank, only the high pressure fuel pump for the common rail.

#12: Re: Intermittent power loss Author: nashy, Location: kentPosted: Wed May 04, 2011 1:35 pm ---- ok well after reading on here today played about with all the wiring and relays today as today was the worst its ever been AND it seemed to work so fingers crossed and will keep you updated
#13: Re: Intermittent power loss Author: Seabook, Posted: Wed May 04, 2011 2:19 pm ---- how many miles have it done?
could be fault injectors?
#14: Re: Intermittent power loss Author: cosmicdance, Location: Leeds, UKPosted: Wed May 04, 2011 3:39 pm ---- Glad to hear it's got better anyway Nashy.
Which wires did you play with?
There's possibly a loose one somewhere.
Andy
#15: Re: Intermittent power loss Author: nashy, Location: kentPosted: Sat May 07, 2011 12:18 am ---- BAD NEWS !!!!!!
its still playing up .... i put bottle of redex in with fuel and it stops ??????? so maybe injectors ?????
keep you posted
#16: Re: Intermittent power loss Author: cosmicdance, Location: Leeds, UKPosted: Sat May 07, 2011 12:53 am ---- It's definitely worth getting it to a reputable auto technician (not expensive Peugeot!) to get the fault codes read.
If there is a fault with fueling etc then it should come up on the diagnostic machine as yours sounds very consistent.
Andy
#17: Re: Intermittent power loss Author: nashy, Location: kentPosted: Sat May 14, 2011 10:18 am ---- ok
happened the other day again i got the right hump and drove it in 2nd gear screaming the balls of it.....
it made some weird noises a bit of smoke and since then it drives a lot smoother and i aint had the probably since so fingers crossed
#18: Re: Intermittent power loss Author: cosmicdance, Location: Leeds, UKPosted: Sat May 14, 2011 11:55 am ---- Yes I have cleared mine before by thrashing it. Not redlining though!
usually it has started it again at a later date though.
I had my EGR valve replaced last week and have been on a motorway run for 70 miles today and it hasn't missed yet.
I will let you know if this is consistent though.
Andy
#19: Re: Intermittent power loss Author: cosmicdance, Location: Leeds, UKPosted: Sat May 21, 2011 6:43 am ---- I had the EGR replaced a couple of weeks ago and the intermittent power loss hasn't happened since.
Hopefully this will have sorted it.
Until the next problem!
Andy
#20: Re: Intermittent power loss Author: stevo2709, Posted: Wed Oct 09, 2013 3:01 pm ---- Andy did the problem ever return after replacing egr valve? Thanks
#21: Re: Intermittent power loss Author: cosmicdance, Location: Leeds, UKPosted: Wed Oct 09, 2013 11:49 pm ---- Yes the intermittent power loss returned again after Replacing the EGR.
In the end it was the crankshaft sensor which was faulty.
Got that replaced a couple of years ago and its been perfect power wise ever since.

#22: Re: Intermittent power loss Author: gazza82, Location: South BucksPosted: Thu Oct 10, 2013 8:00 am ---- My 1.4 hdi's power loss was the cat ... the core collapsed.
Not easy to diagnose as I had a problem with the glow-plug relay at the same time. But after curing that and losing power again on the motorway decided to check in the cat pipe ... not a pretty site!
#23: Re: Intermittent power loss Author: hoganblue, Posted: Sat Jul 26, 2014 6:11 am ---- I have a 206sw Dturbo which suddenly beeps and stops ! was told it was the crash collision sensor. This was reset at the garage but today has done it again ! No I have not had a crash or bump . Anyone know how I can remove this please.
