Hi all, new to forums please forgive me for asking this!

I have read, many, many threads about the depollution problem since my 207 gti 175 thp threw up the problem the other day.

I'm very close to taking it to Peugeot to have the timing chain done as my symptoms are very different to any other ive read!

It started with the check oil message coming up and then the temperature gauge jumped straight to the highest point and the warning of temperature too high with the STOP sign on the dash.

At this point the depollution warning didn't show up, the car was running normally and turbo was boosting normally. parked up, fans running continuously and then the battery died. Charged over night, started the next morning and now I have the depollution warning, no turbo but the temperature problem is fine!?!

I have purchased a Diagbox tester and it continuously throws up three fault codes,

P0444 - Fault Purge Canister Solenoid Valve Control
P0245 - Turbo Regulation Solenoid Valve Control Fault
P0034 - Turbine Discharge Solenoid Valve Control Fault

All these are "characterised" as short circuit to earth which leads me to believe its electrical but I don't know where the first two solenoids are to check?!?!

Help me please pug gurus :nono:

My apologies

Sorry Guys, didn't mean to jump in with the help issues!

My name is Gavin and I'm from Newcastle, I've owned my Black 207 GTI pack 175 THP for about 4 months now, my first Peugeot since a random old 406 years ago!

When I get time I shall try and upload some pics as I'm very proud of my baby!

On a different note, I have actually sorted my previously mentioned problem, after all my searching and fussing it turned out to be a blooming fuse!!!! depollution fault gone, car running better than ever and no warning lights!

Looking forward to being a member and hopefully keeping the Pug for a while!

Welcome to the forum Gavin, I'm Andy. This is the problem with self diagnostics as Codes can be logged for something that on face value seems unrelated. What has probably happened is that the fuse feeds those solenoid valves and when it blew they lost their supply voltage. The ECU detects a 0 voltage situation and flags they are shorted to earth because that is what it has been programmed to do under those conditions. This is why careful diagnosis is needed rather than take it at face value, still all sorted. I don't have a problem with people jumping in with questions, at least you sound keen to learn.

Thanks for the reply, I'm a keen DIYer, wouldn't say a very good one but I like to know whats going on with my car!

Hopefully I'll be able to add to the forum rather than just pester people!

I have the proper Diagbox plugs and software if anyone near me needs to check things?

Doesn't matter so much how good you are but that you are keen to learn, listen to others and at least consider their advice, the rest comes as you build your experience. Contributions are always welcome so long as they are positive. As for asking questions, Pester away we are all here to help each other.

on an unrelated issue, how do you add a signature at the bottom of your posts? is it a newbie thing that you have to be posting for a while?

Look for the User CP link towards the top of the page, click it, then look on the left for the Edit Signature link and you can create away!

Hi!
Are you saying a dodgy fuse caused your depollution system faulty problem?!
I'm totally new to bring a Peugeot owner, I don't know a thing but really want to learn!
Please could you explain how you knew it was a fuse and not a mechanical fault?!
Many thanks

This thread is not so clear but there are other threads about this fault that tell you it is the fuse. The clue is in the fault code which has a bit missed off the end in this thread because they should all have the words "short circuit to earth" after them. The reason for that is that when the fuse blows the circuit feeding those valves looses its power which in turn means that the Engine Electronic Control Unit (ECU) "sees" no power from them. Don't know who thought of phrasing the fault in those terms, think they were deliberately trying to confuse but that is what the ECU is programmed to report if that condition happens. It is worth bearing in mind that ECU's sometimes flag up fault codes that are a bit obscure or even totaly irreleavant to the actual fault. I think the one you mentioned about misfire is another ambiguous one. Sometimes you have to understand how the system works to know why certain codes are flagged up. Cars are not hugely complicated and if you want to learn there are plenty of members who can help you.

So it could just be a blown fuse which has caused my car to be with the mechanics for the last month then?!!
Well, on the positive, at least I'm learning. I know what a solenoid is (I think!) But, from what I've read, the solenoid is to do with starting the car. If that was the issue surely there'd be a lack of power? Which there isn't.

Peugeot 207 gti fault code p2263

Hi all am wondering if any one could help, I purchased my 2007 Peugeot 207 gti in April 2015, at what I thought was a legitimate purchase, only to find a day later it had issues, after spending hundreds/over a thousand on her, I still have an issue. Fault code p2263, turbo pressure measured too high. With this the engine management light comes on and the car loses power/enter limp mode. Originally I had issues with the old turbo being worn, although the car has only done 40000 miles. I have also replace the fuel pump, had a full service, among other things renewed.

Any help would be greatly appreciated guys, as the car is a gem.

Cheers

as trustme says, u have hijacked someone else's post, should really of started a new one, but as its season of goodwill will give u some advice on it. P2263 will either be your BOV or the Turbo pressure control valve. Pretty common on the THP engines.

Sorry guys I am new to all this forum thing.

Bov? Meaning blow off valve?
Also where would I find the turbo pressure control valve within the engine bay.

Thanks

To Jeremy1313

Hi Jeremy I'm unable to reply to private messages so I thought I'd put it in here and hope you see it, as above really, it's a 15 amp fuse, blue I believe, located in the fuse box of the engine bay, roughly in the middle if memory serves, however there's no harm in taking one out at a time and checking if it's blown, hope this helps
