#1: 1.4 hdi ... lack of power Author: gazza82, Location: South BucksPosted: Fri Feb 15, 2013 12:44 pm ---- Yes I know a 1.4 hdi isn't quick anyway, but it's even slower than usual.
Any incline slows the car down to around 56 .. slower than the artics on the M1 and it struggles to get over about 2500-3000 rpm in 4th and 5th. ALmost like it's being strangled on the turbo isn't pushing ...
It's got just under 105K on the clock and it's regularly serviced .. by me!
Anyone have any ideas where to start?
No codes or EML ...
It has in the past given ERG valve errors, but that seems to have sorted itself.
Still, it passed the MOT today!

#3: Re: 1.4 hdi ... lack of power Author: TelaKeppi, Location: FinlandPosted: Fri Feb 15, 2013 1:44 pm ---- MAF sensor, if turbo sounds ok.
#4: Re: 1.4 hdi ... lack of power Author: TheGTIlad, Location: LeedsPosted: Fri Feb 15, 2013 5:46 pm ---- If it has a dpf, then the dpf may be partially blocked. If someone round by where you live has access to/owns a copy of Peugeot Planet/Diagbox, then personally I would ask them to plug it in and check the condition of the dpf filter. Your car may need a re-gen.

Agreed ^^ it was a dodgy sensor causing this exact problem on the one i used to have

The 1.4hdi doesnt have a dpf.
#7: Re: 1.4 hdi ... lack of power Author: gazza82, Location: South BucksPosted: Sat Feb 16, 2013 7:39 am ---- Just about to reply with that ...
I've got PP2000 so I'll double check ... I used my Sealey code reader yesterday.
If the MAF sensor is like the MAP sensor on my Alfa, then it doesn't show up on the code readers unless it's completely dead. It has the same affect ... no top end power!
Thanks guys ... I've got something to start on ...
#8: Re: 1.4 hdi ... lack of power Author: gazza82, Location: South BucksPosted: Sat Feb 16, 2013 1:03 pm ---- Quick update: removed MAF sensor and found one of the two heat elements were broken off .. so that's it then ... replacement ordered ...
Took the opportunity to clean out the oil from the intake pipes ... and replaced the air filter.
#9: Re: 1.4 hdi ... lack of power Author: gazza82, Location: South BucksPosted: Tue Feb 26, 2013 4:38 pm ---- Update: Swapped out the MAF (and replaced very cracked aux belt and a very vet dirty cabin filter).
Monday morning, nothing really changed. Still sluggish ... was expecting to have to send MAP back. Coming home floored it to get on to busy roundabout ... and Pug went like a blue "bat out of hell" .... seems the BSI took a while to recognise it was working!
#10: Re: 1.4 hdi ... lack of power Author: chief93, Location: United KingdomPosted: Tue Feb 26, 2013 5:01 pm ---- Glad its sorted for you!

ECU not BSI. Whenever you change a sensor you should shut down the system, then reboot so that the ECU can relearn its parameters. Sounds like BS, but does make a difference.
#12: Re: 1.4 hdi ... lack of power Author: gazza82, Location: South BucksPosted: Thu Feb 28, 2013 2:07 pm ---- Oops meant that.
On my Alfa I can clear the settings with my diagnostic software so it re-learns straight away. Couldn't find anything in PP2000, so didn't worry.
Anyway, took Pug up to Coventry and back yesterday, and I am sure it's going better than ever. So maybe the small metal strip falling off did me a favour (albeit not my wallet!).
I'll have to see how the MPG looks ... but pi$$ed off a couple of Porsche drivers on the M40. Didn't seem to like being overtaken by a small blue 206!

How do I do that? Reset the ECU?
I'm having power issues again. Last week it was the glow plug controller and put car in limp mode. Changed that and it was fine. For three days sat with battery out as that unit is on back of the battery box and impossible to get to without taking box out.
Cleared the fault and that reset the EML light and on Tuesday was running perfectly.
Now, power gone again and feels "strangled". only fault is supposedly the clutch pedal switch P0704? which, considering I don't have cruise control, seems like it could be a red herring.

Im fairly sure MAF sensor won't give any codes when it goes bad. I replaced mine last week, the car had flat spot at 2900rpm and with new (genuine VDO MAF sensor) It's now resolved.
#15: Re: 1.4 hdi ... lack of power Author: gazza82, Location: South BucksPosted: Sat Jul 27, 2013 4:22 am ---- Thank Tela, but that's to soft boot the BSI .. I probably need to reset the ECU.
I'm about to plug my head under the bonnet and run a few diag checks with PP2000 so I'll see what happens.
#16: Re: 1.4 hdi ... lack of power Author: TelaKeppi, Location: FinlandPosted: Sat Jul 27, 2013 5:39 am ---- Sorry about that, was thinking BSI instead of ECU www.autodiagnos.com/si...ets_ad.pdf
Looks like a trip to your local Pug dealer. I had my BSI reflashed last fall (http://www.206info.co.uk/Forums/viewtopic/t=52648.html), they told me the software could be updated if newer version was available. All data had to be manually input after the update. Could be the same with ECU.
#17: Re: 1.4 hdi ... lack of power Author: frostymuzic, Posted: Sat Jul 27, 2013 6:50 am ---- HI there. I have had the very same problem with my 1.4hdi over the last year and got it sorted about a month ago, she just would not go up hills, I had taken her two several places and no joy,
I had a new turbo ,MAF and EGR, and still no luck various diagnostics but nothing, until another mechanic drilled out the CAT and hey presto Thrust, really good thrust, drives like a new car pulls all the way to 90.so you need to take the cat off and give it a good inspection, even when it was tested on the car it read ok so don't be fooled like I was, my car has done 163000 and is still well just going, all the power and I've blown a piston ring ,but you cant have everything, Hope this helps,
DAve
#18: Re: 1.4 hdi ... lack of power Author: gazza82, Location: South BucksPosted: Sat Jul 27, 2013 9:07 am ---- Cat core had collapsed .. de-cat and power!!! (well 68 horses anyway!!!)
Core was like a large ball ... should have been a cylinder filling the box. Was rolling around and blocking exhaust pipe.
