Hi has anyone any problems filling up their X5, mine takes ages to fill up as the pump keeps cutting out, I have tried every angle possible and many different filling stations but doesn't make a difference.

Has anyone any ideas?

Thanks

Sometimes I get the same problem and find pulling the fuel nozzle out a little (1/2" max) helps. The new X6 has an anti-misfuelling device in the fuelling pipe and that means you have to keep the nozzle well in!

I have a problem filling up..... mainly the fact that it's usually over 100 quid these days!!
Perhaps there's a blocked breather pipe somewhere in your fuel system? As I understand it, the concentration of petrol/diesel fumes at the nozzle is what shuts the pump off. Someone with a bit more experience of the x5 might be able to tell you how to test vent lines.

No problems at all still takes 110 off me everytime.

Hi

I read loads about this last night (sad I know) and there are suggestions out there like replacing the whole filling neck but the guy who did it only found out it did the same again. He discovered it was the actually the pump at his local filling station and didn't have a problem with the others. Some of the others suggest not putting the nozzle in all the way helped or slightly turning it to say 11 o'clock.

One person found there was gunk that was blocking the breather valve.

I'm not sure as there seems to be no definitive answer. But you could give the last three a go before you spend hard earned cash.

I've had trouble with one pump if i remember rightly, might be down to a faulty sensor in the pump pressure sensor, as its only been the one pump.

LOL, ok..I work in the car publishing/magazine world and was speaking to one of the main petrol companies (its the green one ) head of marketing today, there are only a couple of manufacturers who actually make the pump that delivers the fuel for all of the petrol companies and with out fully wanting to be qouted on this yes he admitted that they were designed to deliver slowly so as to give you time to look at the adverts and pr that surround you whilst you stand there filling your cars up with fuel! Theres more profit in coffee and a loaf of bread than fuel for the garages

Totally agree re the profit as my father had a car garage with petrol station and he always said it was a practical loss leader!

Unless you own that yellow garage near me that charges 10p a litre more then the tiger one 3 miles down the road ...

Just turn the nozzle or pull it in or out a small bit usually sorts this out i would not go changing any parts on your car anyway mate i think everyone who ever filled petrol or diesel has expierenced this at some stage really annoying at times and some of the pumps that are really slow piss me off waiting ages for it to fill. I do get so pissed off most of the time i just stick in 50 and walk away

guys, this is no joke i had the same issue that gareth82 is reporting, in the last couple of weeks!

i did a round trip of 750+miles after xmas, through the new year, so i had ample oppty to test different vendors as well.

first it was at the red and blue guys who also has the no 1 supermarket chain in UK:) i thought either they had bad fuel in their underground tank or a bad nozzle. i had to pump really slow, pulling nozzle out half way. turning it in all sorts of angles did not help.

what it is is actually the diesel rises up through the fuel tanks neck and when the nozzle senses diesel on it it shuts out (nozzles are designed to stop when the tank is full, they do htis by sucking in from a very small hole at the tip of the nozzle. usually it will suck air, but the moment the tank is full it will suck in fuel, and that stops the nozzle. in this instance because diesel comes up the neck bubbling up, it gets through that small hole and stops the pump although the tank is not full)

i pumped about 60L with the greatest difficulty, whilst paying i asked the cashier as well whether anybody else complained of this issue. she said no

later on (in wales) i had to fill up again. i had the same issue, but unfortunately it was the same blue/red supermarket chain (i like them cos they give points for shopping!)

now i thought this was a bad joke, obviously, cos it takes for ever to pump. there can't be anything wrong with the diesel as well as the car ran as normal, normal mpg, power etc.

next i had to pump in cornwall and it was the yellow guys with red lettering DAMN! i had the same issue again!!

convincing that it wasn't at all bad fuel or a bad nozzle.

so its definitely my car, where when i fill up at speed (nozzle trigger fully pressed), diesel rises through the neck and that makes the nozzle stop!!

i've read ealier on this thread about the breather pipe. surely there has to be a breather pipe to let air out as the tank fills. but i have no idea where that is.

pls help if you know something about this..

thx

guys, i'm sort of desperate on this, any help is appreciated .

cheers

Have a look here to see if it helps....it's a copy of the BMW Tech Manual. Might help you find the breather/vent lines. Not sure if there's an anti-siphon device/valve in there which might have malfunctioned and is causing fuel flow to backup into the filler pipe. It's all I can think of.

waw!! thanks, that's ULTRA informative!

i've fished out the bit about replacing the fuel filler neck which shows the breather tube, now my only hope is that that's where my problem is...

thx

I dont have this problem if I let the tank run near empty before filling and have been doing this from shortly after starting the topic with no problems at all.

Must try to fill again from half to see if I still have the problem (will try today and report back)
