Dear forum members,

I have a Peugeot 207 GT 150HP 1.6 16V Turbo and it has many many problems!

This car has 96.000 km on it and it has already changed the engine two times,
For the past 5 months the car has a fault showing the anti-pollution indicator!

At first, we connected the Peugeot Planet Diagnostic, we found faults concerning misfires! We have changed all the ignition coils and spark plugs and the problem was solved.... After 1 month, the anti-pollution came back on! This time, catalytic converter! We have changed it too and all ok...

After, 1 week the car had a problem with the Turbo Solenoid switching valve, we have installed a new one and all ok,


Now after all these problems, when you start the car sometimes it won't accelerate at all, you see the anti-pollution fault again and it misfires!
I have connected the diagnostic, and sometimes i get only a fault saying about the fuel pressure of the fuel pump but mostly i get these:

P2261 Permanent fault, Turbine discharge solenoid valve
P1337 Misfire Cylinder 1
P1339 Misfire Cylinder 3
P1336 Misfire on undermined cylinders


You start the car at morning, the car won't accelerate at all! You switch the ignition off, restart the engine and everything is ok!!!!!!!!

The owner of the car is going crazy :eek:

Does anyone has anything to suggest on this one?

Thanks in advance

The engine was changed by a Peugeot Original dealer at 35.000 because of "oil burning"!
Peugeot took this in the warranty thankfully!!

I haven't checked the timing chain because Peugeot dealer has already did,,

Can this be an ecu problem? Maybe a software bug that needs reflashing with newer version?

Hi I'm having exactly the same on my 207 but mines the gti 175, no matter what I change can't get rid of this de pollution problem, but mines showing the fault cold p0204 which is a control fault with injector number 4! Peugeot have told me my ecu is faulty and needs a new one but some how I don't believe them think they are just after selling me an ecu at over £1000! But like you said the car goes in limp mode when it's started but once my oil temp is up i turn car off and back on and it's fine but still showing a fault :s past few days though its not showing no fault or going into limp mode, anyways I've got some peugeot tech guys working onit today so if they can shed any light on this I will let you know so you can give it a try.

I don't quite understand Ollie. If a pug dealer are telling you the ECU is faulty, and you buy the ECU on the strength of that advice and it doesn't cure it, then they're liable for the cost. What have you got to lose? And why do you think you know more than they do?

What will you do if your second lot of Peugeot guys say it's the ECU?

Or what will you do if your second lot of Peugeot guys days it's something different to the firs lot of Peugeot guys? Who do you believe? What makes the second lot any better, more trustworthy or more highly skilled than the first lot? Or vice versa?

Sounds like a load of fannying about going on. Get the diagnosis in writing, get the new ECU. Best case scenario the problem is solved, worst case scenario you're no worse off than before.

I haven't checked the timing chain because Peugeot dealer has already did,
And we all know what an assumption is the mother of...?

I'm just not convinced chopper, at end of day all peugeot did was plug it in to a diagnostic and say yeah your ecu is knackered, if it was my ecu then I doubt the fault would be intermittent, I did have a generic remap put onit 3 weeks ago to try get the eml light off as I thought it was been caused by the decat I have on it, they said though although the map is generic they can alter the codes slightly to tell the ecu it's been decatted so maybe they get these codes wrong and its thats why it's doing, the car is under warranty anyways and the garage I bought the car from is paying for the work so I've got nothing to lose, if it is the ecu he's just going to cut his loses and swap the car, they have another 207 in but it's the 150bhp gt, thing is do I want to get another 207 when they just seem a problem car?

After market remap, just had a call from garage and they said the wire going to injector number 4 hadn't been reattached properly when number 4 injector got replaced when I bought the car so fingers crossed this had sorted it :)

Why do you think an intermittent fault can not be caused by an ECU? Intermittent grief is classic dicky ECU failure. It's relatively rare that they just die entirely. You've found the fault, bit it nothing to do with your bizarre reasoning.

I've made a few calls yesterday to some peugeot experts!

One of them was convinced that it's an ecu fault! He said that he changed many of them and he did solved the problem

With all the fault codes your getting this may be true it might be your ecu, but take it from my experience peugeot can get it wrong, they said it was ecu and turned out just to be the wire going to the injector, yet peugeot was convinced it was my ecu, if I was you I would get a auto sparky in to test the wires or send the ecu off for testing, if it turns out its your ecu, go to www.ecu-repairs.com they will completely re wire your ecu for half the price it is to buy a new one from peugeot and they give 12 months warranty just like peugeot would buying new, so why buy new? I would defo 100% make sure it's your ecu by starting with the cheapest solution wether that been getting an auto spark in or send ecu off for testing, don't just take peugeots word for it! Good luck and keep us posted.

Same problem solved (until now)...

Hello to everybody.
Last year I had the same problem with my 207 GT THP 150.
After a long week with the car stuck in the dealer's garage, the high pressure fuel pump was changed (twice) and the problem was solved, costing me about 500 euros. The only indication was the low fuel pressure before the injectors. This caused the missfires and all the fault codes shown in the engine diagnosis.

I had the same problem, turned out one of the big wires had been pulled out its socket from the back of the engine, simply plugged it back in and have not had a problem since (mine was just under the air box at the right hand side)
