Other car - Can anyone help?

[tommy89]

Hello everyone!

I have been lurking around here but not posting for a while - still hoping to spot my old Twingo!

I have a little problem I wonder if you can all help with? We recently got rid of the wifes 04 scenic as it was due a cam belt and was generally getting a bit annoying with clicks and crunches etc.
We replaced it with an 06 Peugeot 307 1.4 petrol (POWEEER!) anyhu - we have done about 800 miles in it in 2 weeks to try and throw up any issues it has whilst it still has a little warranty (not sure how good the warranty is though)

This evening I went to take it out and I turned the engine on to be met with "antipollution fault" and the engine light on on the dash.

Does anyone have any experience of things like this? This is our first "fancy" Peugeot (had a base 206 last year)

I have chucked some redex in the tank - but did fill it up at a supermarket before.

its on 62000 miles and just had its cambelt done. Thanks for any help!

Tommy.

My mum has this problem on her 207 aswell, does it drive fine?
Had a look and I think it could be one of a few things wrong, would it be best to see if it's stored any fault codes?

couldn't tell you tommy, anti polliution fault is a very generic thing really. especially with peugeot's! is they are just about the most unreliable cars on the road right now (sorry for the negativity), the anti-pollution can relate from anything to the map sensor to the catalytic converter and urea (pigs piss basically...nice eh?) treatment that they use in their post cats

the best thing to do will be to get a fault code reading and let me know the fault code. i have full access to servicebox premium, so i can give you the peugeot specific fault code meanings. are there any symptons at all i'm wondering??

 

[tommy89]

It drives nicely - we have only had it for just about 2 weeks so Im not sure if it has changed from its past drives. It pulls very well and revs to 4000 rpm without problem (I don't usualy drive it like that - just wanted to see if it was in limp mode)

It has always made a whiney noise from the engine - not a massive one but it increases with revs and sounds like a belt (to do with the new cambelt??)

Last week I did let it go very close to running out of fuel (25 ish miles with the red light on) would this make it suck up crud and knacker the fuel filter?

Also it may have a very slight blow on the centre exhaust (I cant really tell as it may just be the exhaust noise of this car)

I have a generic fault code reader but I cant find the port (and doubt mine will fit)

sorry! didn't see your post Oscar- I have learnt that these 307's aren't great after buying it should have done research before but the scenic was doing my head in (sound reason to buy a car quickly!)

I will try and get my code reader onto it as soon as I can - currently googling the location of the port. Thank you both for your help - I hope this doesn't end up costly! its only meant to be a nice cheap second car.... Knew I should have got a 206 - even I can fix those!

the data link connector's in the arm rest / centre console ''thing'' in a 207 if that sounds familiar to you tommy? i really am not a fan of them, the 207 GT / GTi THP's for example when they go, they go like stink and are so easy to tune up to megane power ... but you won't get very far before the engine chokes and dies. inlet valves get covered in carbon like an old diesel (remember how very very old 80's cars and previous had to go for a de-coke?) yep .... only on a peugeot! also, the HDI's and the petrol range BMW engines are notorious for timing belt issues. this is the same engine you'll find in the Mini, i'm genuinely not a fan of them but it's not to common seeing the 1.4's having such issues.


if it's just in warranty and not by much, then don't sweat it. take it to peugeot and let them resolve it. i'll help in any way i can though if you want to do it yourself with good places to start your diagnostic snooping

 

[oscar]

forgot to mention, that's the location in the 207. the other common DLC point is under the steering wheel in a peugeot

 

[tommy89]

Hi Oscar - Thanks for your help - Found it after a bit of breaking of plastic ashtrays My crappy fault code reader may have fond 1/ 2 codes - but I have no idea if they are actual codes or mean anything.

It showed P0170 or P0170 p - Mean anything to you?

Looking around the car - the tip of the exhaust has a black rim of soot around it and sortof "putts" from time to time when on idle. Not sure if that is useful to know?

It still pulls nice and hard (well as hard as a 1.4 can) but does suffer from being a bit juddery (feels like you are in too high a gear)

 

[oscar]

it's something to do with fuel trim, that's not a peugeot specific code. with fuel trim i would look at the MAF / MAP sensor. i believe your pug should have a MAP sensor ... but knowing peugeot and their backward ways they'll probably run a MAF sensor. anyway, i'd be looking at getting the diagnostic machine on it. check the fuel trims, let me know what they are using live data reading ... or w/e your particular code reader will call that function!
what's the readings for O2 sensor bank 1 / bank 2 ?
are you able to gain access to the MAP / MAF sensor using live readings at different RPM?
what's the fuel trim settings, and if possible can you get emissions readings? i don't expect them to be hugely accurate but this can be the give away when tracking down problems like this

the MAP sensor would have your car running rough / feel down on power. the problem for this particular code is that something is making it run lean, so your ecu's fuel management is throwing in extra fuel to try and compensate and the result is your catalytic converter bank 1 (pre cat oxygen sensor) is telling the ECU to calm down.

 

[tommy89]

Wow! that's some knowledge right there! thank you My code reader is not very good and only managed to pull out those codes. Its a little 18 quid amazon thing so don't think its up to much.

I will take it into a mates garage tomorrow and see if he can hook it up to a real machine and try and get those figures.

May sound a dopey question - but would cheap/ bad fuel cause this issue? I only ask as I filled up at a garage that has had a reputation for bad fuel before.

Also - could I have caused this fault by running it on the red light for 25 - 30 miles? By it sucking up gunk from the tank?

Thanks again Oscar

if you use the search bar on here, i uploaded most of the common OBDII codes which are universal and some are unique to renault. instead of trawling through the fault code lists which are lengthy, the search bar will be your new best friend

technical-stuff-f120/eobd-trouble-codes-rs133-engine-management-t11581.html

P0170 Fuel trim (FT), bank 1 - malfunction Intake leak, AIR system, fuel pressure/pump, injector(s), EVAP canister purge valve, HO2S

 

[tommy89]

Wicked! Thanks for that - I will give my mate a ring tomorrow and see if I can get it in to see him. God I hope it isn't the injectors or something expensive! this was supposed to be a cheap second car (no such thing I suppose)

Ive favourite the link you posted! think that will become invaluable with owning this car!

 

[oscar]

aye man, it could be a cause but again you really don't want to make assumptions. in all honesty, take it to your mates garage tommy and let him find the route cause because the first thing i'd do on the fuel system is to run a pressure check. if it's low on pressure, there is a blockage somewhere and as you suspected ... this would indicate that gunk / dirt may have caused a blockage in the fuel filter which would explain the engine running lean (not enough fuel) but then again there is also other probable causes which would lead me or anyone having a look at your car to believe that it won't be the fuel system (if the fuel filter was blocked slightly and making it run lean, then it wouldn't be physically able to correct it by making it run rich) but i do believe peugeot's are always engineered to run slightly lean.

need to run a vacuum test on the manifold and PCV system, fuel pressure test and emissions test to make sure the problems solved so i don't think this will be a job for doing it at home when nobody has that sort of equipment diagnostics are a mind melt, i really don't enjoy it either



if it is the injectors i wouldn't worry about it, they can be cleaned and tested very easily and for cheap too. one of my friends owns 207oc and has a 207 1.4 so may share the same engine and has a mountain of spare parts so if you need anything give me a shout! infact, just sign up (all the engines are the same) your man is JACOB the site owner

 

[tommy89]

Ah that makes sense! I won't tell the wife that there is even a slim chance I caused this problem running it very low on petrol. I will get it straight in tomorrow after work if he stays late again working on his own car. We almost bought a 207! I will yet myself onto that site and keep an eye out for any tips to keep this thing alive for asking as possible! I'll try and keep you posted with what this car is actually doing to itself! thanks again Oscar - hopefully it is t as serious as the massive engine light made it seem earlier

 

[tommy89]

Had the car hooked up to a code reader today that my mate has at his house... but the engine light and warning went off yesterday.... I put Redex in and ran it for a fair while down the motorway and it just went off!

The code reader only found the fault I had mentioned - so my mate deleted the code, and says to see if it comes back on - does this sound okay? or am I killing the car?

(when I say mate... I mean ex school friend that lives near me - so I don't mind taking it to another garage if his decision doesn't line up with better advice on here ... makes me sound dead harsh there as he was being helpful, but I don't wana kill my car)
