CAR THREAD... Seat Ibiza 1.4 TDI

[woll]

Got an '05. It randomly cuts out. It was a lot worse around 6 weeks ago before I serviced it. Serviced it and it seemed to cure it until today.
Nothing is ever the same when it does it. Some times it will go when i'm thrashing it, others when i'm pootling. Sometimes when its cold sometimes when it's hot and any amount of fuel in the tank.
I think it's electrical, possibly fuel pump. When it starts to cut out it starts to kangaroo as if it's running out of fuel. No matter what I do with the throttle or clutch it will die. The only thing that helps iss when it starts to die turning the ignition on and off again.
Any ideas?

could be something as simple as M.A.F. (mass air flow sensor) telling your computer to shut down, very common problem on vauxhalls (i know yours is seat).

sounds like you could have an air leak in the diesel system also typical of your description, check for leaks in the fuel lines etc

final thing i can think of off the top of my head would be the fuel pump as you suggested,

if you can i would find someone who could plug it in to there computer and read the fault codes the M.A.F. sensor is a couple of quid but if its not the fault you dont want to waste money, if its cutting out there will be fault codes on there

I forgot to add I've got an OBD2 code reader. The only errors it comes up with are EGR fault and Turbo solenoid fault. That's because it won't clear the faults and when it was in the garage last week the plebs forgot to connect the vacuum hoses and the sensor to the box they connect upto.
I don't get an engine management light or anything come up when it happens. And I don' think that it's a problem air in the lines because it doesn't happen regular enough and has no problems starting. I've been along the fuel lines and there's no sign of any leaks.
The MAF sensor is a good possibility, a friend said he had a similar problem with his 1.9 golf and it turned out to be that.

obd2 code reader is no good for that car, you need vcds. jump on to one of the vag forums and you'll find someone local who might be able to help. Does it die completely or just drop back to tickover? If it dies completely you could have a dicky injector or sticky turbo vanes, the engine shuts down to prevent holing a piston, if it just ticks over maybe maf or pedal sensor but read the codes with vag com and that will help. looking at the live values can give you a clue too.
egr and n75 faults usually come up on generic readers not capable of showing diesel specic faults

Starter solonoid? Blocked EGR valve? You should be able to tell if it's the fuel pump by just listening to it.

Jump on a VAG forum and get someone local with a VAG-COM. They're pretty common on the forums. You'll be able to do full diagnostics and also fun stuff with some of the car's convenience settings.

How much is VAG COM? An where can I buy it? I may just buy it myself it'd be handy to have I seem to have a habit of buying VAG cars.
Correct me if I'm wrong but a stuck/dicky EGR would just stick it in limp mode and come up with an error code?
When it dies it splutters as if it has run out of fuel then will conk completely. But if i flick the ignition off and on again it runs fine. Which makes me think it's electrical.

Hi just read your post

I dont no if this is any help but i had a simlar problem with a ford focus, Which kept cutting out at low revs, Well it turned out to be the cam shaft sensor, Once it cut out if you started it up again it would run fine for a while then just cut out as when it felt like it,
If your seat has one mite be worth a look ???

[Clutchy]

Sounds like its going into limp mode to prevent engine damage, I know it happened on my dads seat and it was down to the turbo and was rather expensive to fix, ill ask him for more details when I see him next but for what I can remember the symptoms are the same

a freeware version of vcds/vagcom can be downloaded from rosstech's website, a full version can be found online through torrents etc.

definitely sounds like an injector/loom issue. could also be a lift pump issue depending on the age of your car if it has one.
I got a hooky vcds off ebay for £20. worth every penny.

I work at a VW/Skoda specialist so if you are local I'll happily take a look mate, I would say its one of the relays that power the ecu and fuel pump up, they are right under the drivers side of the dash and you have to dismantle the side of the dash to get to them, Injector looms usually give a missfire fault code and don't usually come and go on their own.
it has the right fuel in it yea, no bio or cooking oil or petrol

Have you cleaned the EGR valve and MAF sensor? I thought those were common problems on all these sorts of engines.

[jimspeed]

both egr and maf will not give those symptoms tho, the 1.9 tdi's are really good but the 2.0 twin cams are best avoided in my opinion, turbo's will go but only when abused really, dmf's are usually ok unless its been doing lots of towing or town work and the injectors were ok untill around 2007 when they changed to siemens and had issues but most of those were 2.0 cars. I wouldn't worry about buying one with 300 K on it to be honest

A dodgy MAF sensor shouldn't cause it to randomly cut out, but it will cause poor performance. If you unplug it and the performance improves, then you have a dodgy MAF sensor.

I've read in car mechanics magazine that there's no point buying cheap MAF or lambda sensors for VW diesel engines, get an OEM part (not necessarily genuine, but OEM) if you want it to work.

For random cutting out problems I tend to look at crank or cam sensors. They're cheap, and a knackered one will work a bit when cold and then fail when it gets warm.

If you're not getting a little light on the dash, then don't expect to get a great deal of help from scanning the codes. If the ECU knew that something was causing enough trouble to make the car break down, then it would turn the light on.

Bugger wish I'd seen that earlier lol just come from Shrewsbury.
