Hi
I would appreciate any suggestions for my 307s problem.
Its a 2003 307 1.4hdi estate with approx230k miles done. Oil and filter changes every 7 to 8k miles and always great to drive. Recently it started to cut out when revs dropped at lights or a junction, not every time but approx 2 times out of 5 changed the fuel filter and it seemed to be ok for about 3 weeks and started being naughty again. I checked the tank for dirt but it seems fine. No problems on a journey, good acceleration (for a 1.4 :rolleyes:) engine runs smoothly, really like the car but this problem is starting to get worse and the wife is now reluctant to drive it. No Peugeot garage within easy reach and the local garage is saying try this or that and does'nt seem to have any idea. A friend of mine said that there is a pressure sensor on the pump that might be the cause. The engine doesnt cut out directly, when I come to a light it will start to hunt and dipping the pedal has no effect and after 5 or 6 seconds it will cut out, suggesting fuel starvation.

Well,
You are not alone. My wifes 2009 207cc 1.6hdi does exactly the same thing. My wife wont drive it now either.
My car has 41k on the clock. If im honest the problem only started to happen when the timing belt was changed approx 2k miles ago.
Mine run sweet..no smoke..or rattles pulls like a train...but when slowing down very very occasionally it will cut out or judder and cut out. Turn her off and she starts and drives although takes a minute for her to settle down. Its defo fuel related. I know Hdi dont need the pump timed although is recommended on Bosch pump.
Could the pump timing be out.. A sealey timing pin kit was used.

Planet at my local garage who is a french specialist says no codes stored.
Its had 2 fuel filters (no swarf inside them)
Airflow meter
Forte cleaner 4 Bottles
Italian tune up too!

Any ideas

Check fuel pipes back from pump to bulkhead as they rub on the engine and start leaking, minor leaks can allow air to be sucked in and cause cutting out at low revs

Do u think the pump timing would cause a 'occasional' cut out..or is my theory right in thinking that it would do it all the time ?

Doesn't the bosch pump have a low speed solenoid ?

Its got the point were Im thinking of part exchange to something else..

No pump timing would not affect the car due to the way it works, third piston solenoid just saves fuel by disabling third piston when high fuel loads are not required.

For a HDI to cut out with no codes must be due to air leak/fuel starvation or to high/low fuel pressure being reported to ECU.

I think there are known issues with Fuel rail sensor on some models and also normal issues with wiring etc which could cause issue when engine moves on overrun or acceleration

Similar thing happened on my other car - Seat Alhambra. I cleaned the earths and ran a few more leads from the various engine earth points back to the negative terminal on the battery. It worked a treat and the car doesn't stall anymore

Might be worth a go...

Its very strange why it only does it at low speed. It will cruise at 40 - 70 mph no bother,
But as soon as you slow down 3rd to 2nd usually when it does it.

It went 3 weeks without doing it then it does it once a week now :thumb:
My wifes losing faith with it..as am I....

Your right it cant be pump timing because it would do it all time.

Why do Bosch put timing holes in the pump ?

Im wondering if its related to the crank sensor..as its the only sensor I had to unbolt to do the belt..Do u think the sensor is not picking up the reluctor ring at low speed or struggles to keep up with change in engine speed ?

I have a genuine fuel rail pressure sensor..a new one in the garage..might be worth trying that I suppose.

Yes worth a double check on crank sensor, check for contamination and gap etc. It possible this could do it but i would expect poor starting as well

For what they cost from euro..I think I will change it for a new one. Euro list 2 sensors..but they are both 3 pin..any ideas which one I need..I thought DV6 engines used the same sensor :nono:

I would have thought the crank sensor would still throw up some codes. Seems like something to do with the fuel pressure sensor. I had this on the 1.6HDi except eventually the cutting out became totally random and codes did show on planet. Put in a new high pressure fuel sensor and it's been fine since.

Would this be the sensor on the injector rail. ???

Yep that's the one. Some say it shouldn't be removed and the whole rail needs replacing but then why would the sensor be removable and sold as a separate item? Changed mine over 10000 miles ago without issue.

Im gonna change the Fuel Pressure Sensor and the crank sensor. I have them both now..not that expensive even for genuine items. Gonna be a parts swap exercise I think..its not going back to the specialist..too expensive.

i have just bought a 2007 207 Hdi My wife went away in it. Then after 50 miles it cut out as she was slowing down at traffic lights. No faults found on the diagnostics. The battery light came on when it stopped. Then it wouldn't restart for over an hour. Got going then it stopped at a busy roundabout in 2nd gear. My wife ended up getting a tow truck with green flag. She won't use it. Lost confidence. Any ideas?

I would start your own thread to get a better response. Crank sensor would be my first test

I had a similar issue, I had a tiny hole on the fuel pipes behind the air box.

I just cut them out and fitted universal pipes in their place.
