By any chance do you use supermarket diesel? Or a non quality diesel? (Bio etc)
Does the speedo drop when it happens?
I think you could use a clean out of the fuel system.

i use bp diesel the speedo did drop so i changed the speedo sensor but still having the missfire/hesitation

Does the speedo still drop though? Is it the same hesitation?
RE: Peugeot 306 hdi missfire/hesitation - paulpope33 - 07-09-2014
the speedo doesnt drop anymore but still the same hesitation

Hmm I'd try cleaning the fuel system then. If you know anyone with peugeotplanet near you ask them to do a diagnostic on your car see what comes up. Probably be some synchronisation error and can then work out the issue.
RE: Peugeot 306 hdi missfire/hesitation - paulpope33 - 07-09-2014
ive had it in peugeot garage theres no faults at all coming up whats best way of cleaning the fuel system out and whats best to use
RE: Peugeot 306 hdi missfire/hesitation - Poodle - 08-09-2014
Don't use anything to clean out the fuel system, especially not products like Redex, the high-pressure fueling components don't seem to enjoy it. The only things really worth checking on the fuel system are the filter and fpr, if you're taking the filter out don't forget to drain the diesel in the housing and clean that out before refitting/replacing the filter.
Isn't this a symptom of as dirty tps? Perhaps worth giving that a clean, think deeturbo did a guide iirc.

Aye don't run anything through the fuel system was gonna say clean out the filter in the lift pump. Clean/replace fpr.
Suprised p0230 code wasn't thrown up or something when you had it checked with the garage.
I've heard to clean out the fpr just get some carb cleaner on it but take out the rubber rings (think they're green) before hand or anything that could get damaged from cleaning.

Hesitation with no fault codes sounds like a MAF issue to me... Could try unplugging it, if the car drives the same or better with MAF unplugged, it is at fault.

ive unplugged the MAF still running the same
RE: Peugeot 306 hdi missfire/hesitation - paulpope33 - 08-09-2014
Could i have a problem with the high pressure fuel pump, when ticking over its fine iam only getting the problem when driving the car
RE: Peugeot 306 hdi missfire/hesitation - vincent1 - 08-09-2014
toms306 says above ( if the car drives the same or better with MAF unplugged, it is at fault.) now you say its still running the same i persobaly would try another maf.
RE: Peugeot 306 hdi missfire/hesitation - paulpope33 - 09-09-2014
i have a new MAF on way should have it with in the next 2 days i will replace and reply with results
RE: Peugeot 306 hdi missfire/hesitation - Poodle - 09-09-2014
I hope you bought genuine maf, pattern parts seem to be unreliable at best when it comes to sensors on these.
If you had fuel pressure problems it'd come up with the infamous p0230 code, same goes for cam/crank synchronisation - would expect to see relevant codes.
RE: Peugeot 306 hdi missfire/hesitation - paulpope33 - 09-09-2014
theres been no codes and no managenent light

Well fingers crossed a changed maf sensor may help!
RE: Peugeot 306 hdi missfire/hesitation - paulpope33 - 09-09-2014
i should have it tomorrow /thursday

Second that, keep us updated.
RE: Peugeot 306 hdi missfire/hesitation - paulpope33 - 19-09-2014
Update its turned out that there was to much vacuum being created in the fuel tank the problem was with the breather pipe so i phoned peugeot to get the parts i needed but they told me that they dont supply the parts anymore so i have ended up drilling an hole in the fuel cap so the tank can breath untill i can find anywhere that i can get the part from since drilling hole in fuel cap the car as been running 100% perfect
thanks to all who as helped
RE: Peugeot 306 hdi missfire/hesitation - Poodle - 20-09-2014
Not come across that before, one to remember for future. Thanks for taking the time to update us.
RE: Peugeot 306 hdi missfire/hesitation - madmadmax - 20-09-2014
a brether can be made useing a one way valve and some 8mm pipe
RE: Peugeot 306 hdi missfire/hesitation - selectcase - 20-09-2014
I am surprised the parts are not available
RE: Peugeot 306 hdi missfire/hesitation - welshpug - 20-09-2014
unlikely that is true really, they just cant be aqrsed 99% of the time to order things as they dont keep stocl, its all in warehouses.
RE: Peugeot 306 hdi missfire/hesitation - paulpope33 - 13-10-2014
ive have looked everywhere to get this part i think the only way would be to buy some pipe or have a look round the scrap yards
RE: Peugeot 306 hdi missfire/hesitation - pug306driver - 14-10-2014
did the tank collapse ( bent internals now?? so fuel gauge out?? ) or make a "thunk" noise when the fuel cap was released?? mind you little fuel used and a moderately blocked vent would allow air back in slowly so not noticeable......

one "odd ball" or "long shot" for the diagnosis bit.......
as ever, brilliant forum
RE: Peugeot 306 hdi missfire/hesitation - paulpope33 - 17-10-2014
No the fuel tank did not collapse there was a hell of a gargling noise when i removed the fuel cap from the tank
