Hi,
I have cold starting problems and got the AA out this morning and he got it started but then plugged into ODB and said it was the EGR valve not working properly?
Not sure if he said it was open or closed.
I've been having a look at possible blocking the vac hose to the EGR on this forum and it looks quite easy to do??? Maybe??
Please could someone tell me if this will help with the cold starting and where the right vac hose is. See pictures.
Many thanks

EGR electro valve is on the front lower part of engine near starter motor it has a blue electrical connector. Disconnect and plug the the hose with the Y piece to the other valves on it (should be the one without the white ring)

Thanks Windy1603,
So from that, you're saying it's the one in the picture (bottom picture in list) ?
There is a blue connector under it and it looks fairly easy to get to? It's just which hose to take off and (screw, golf tee) block off?
Will doing this help with cold starting, fuel economy and lack of power?
Thank you for your advise.
Stuart

Sorry I forgot to say in my initial question that the AA cleared the codes for the egr and it started straight away?

Thanks for your input but it turns over fine but just does not fire
So you dont think your battery is worn because the car turns over.
The car will turn over with about 11V on ghe battery. But it will not start with less than 12v.
It is not a Escort mk1.

The battery was tested this morning and the AA said it was fine, I'm not really sure if you're being sarcastic or not as the context is lost n the text?? Could this be the reason it's not catching/firing?
Thanks for your help

Not being sarcastic at all.
Just trying to explain.

If the battery is fine it could be a lazy starter motor not cranking the engine fast enough or you could have low fuel pressure due to a failing injector or similar. When was the fuel filter last changed

Ok thanks didn't mean to offend anyone.
Actually fuel filter not changed for a while!
I've just got the email the AA sent me with the codes he cleared which are P1352 and P0380 and P0401 not sure what this means?
Please help

Sorry just to add: once the car starts it's fine for the rest of the day. Also the fuel economy has decreased recently, maybe 50 miles to each segment on the gauge so about 300 to the tank 😡😡 I can't see any leaks anywhere?

Battery voltage check in reality means nothing. They need to be load tested which means basically a short circuit test through a test meter which measures the batteries load amperage which is the part of the electricity that does the work, the CCA capacity as its called. If the battery is indeed up to scratch and the connectors are clean and tight, including the earth points, then the starter motor is your next port of call as advised by windy. Any battery supplier like Halfords should do the test for free by the way.
P1352 depollution fault, P0380 Glow plug circuit, P0401 Egr circuit.
Just Google " Peugeot 307 fault code number" to read the descriptions.

Sorry but unless you do the basics then it is pointless trying to guess the cause unless we have a good starting point as to the cars state and history if any of faults in the past.

Thanks, I understand you trying to help.
I've had a checkered history with this car and had a few problems probably relating to the DPF. I found the fault which was the fuel cap sensor and I've also topped up the eolys and reset it with planet.
So from what is happening now NOT COLD STARTING -5 temp. I got the AA out, please see start of this thread, he said it was a glow plug problem. I am getting a P1352 error so that would tie in with what he said, also the would stop the regen of DPF? I am also down on power but no mil light.
With all that in mind would it be wise to replace the glow plug relay??

I believe it would on your car. My 307 has the 1.4HDI and the fuel system is Siemens. With no dpf my car was in limp mode because, as it turned, out the glow plugs were all dead. Now normally the temp has to go very minus for a diesel not to start. The first port of call would be to check each glow plug for resistance. About 2-3 Ohm is good. 0 is open circuit. They are a brute of a job to replace as the carbon build up on them in the head can cause them to shear when trying to remove them. Access is awkward to say the least. The trick is to soak them with all the usual formulae's and diesel for a few days then when removing turn them a tiny bit at a time, out then in, to allow the carbon build up to be removed gradually. But there is no guarantee they will come out without snapping off.
