Hi, new to the forum so please be gentle with me.
Last week we bought a 57 plate Golf GT TDI 140 with 50k miles on the clock.
Got it for a good price as it need a bit of tlc on the body side of it but it seemed good mechanically and low millage which was what we was after.
But then we had a problem, after driving 40 miles back home from buying it the car cut out 200yds from home at a junction, no warning or signs just died.
Pushed it to side of the road then came home and got on phone to seller who said he'd never had any issue with the car!
Gt the iPad out and then started googling and came across a few forums including this one with others saying they had similar problems but all seemed slightly different and all fixed differently.
Managed to get car started after cranking it over for nearly 1 min, fired up and drove it up to VW who plugged it in and no faults showed up on vagcom.
Frustrating as was hoping it would show up something to help diagnose it but no.
I changed fuel filter and file lines in and out of the filter housing as they were showing signs of perishing and maybe drawing air in.
Drove it around this week and it has cut out twice since at traffic lights. There is no warning, no hesitation or missing of the engine just cuts out.
Then if I cranking it over for a while it fires up.
To me it it like the fuel has stopped and engine cuts out, then while cranking over it is bleeding fuel back into the system and engine and fires up?
Next on my list would be to replace the lift pump in the tank.
I am only trying these things as they seem to have been mentioned by others in a few post I found on line and they aren't that expensive parts to buy and try.
Suppose what I am asking for here is if anyone else had the same or similar problems or could point me in the right direction of other things to try or replace.
With getting the car at a good price that means we can afford to spend a bit of money on it to get fixed and still have a mice reliable car
Thanks in advance for any help or info

Surprised I've not had any replies or suggestions.
Took battery out to gain access to the glow plug relay underneath the fuse box, and now I have the power steering and traction on troll lights in the dash.
I read somewhere but can't find it that its because removing the battery has lost the basic settings for the power steering and abs.
-
In regard to resetting your ABS lights - take full lock to one side, hold for a second, take full lock the opposite side, hold for a second, then centralise it. Drive slowly in a straight line for about 30 yards+ and the lights should go out. Otherwise a short drive will suffice.
About your fault, I'm really stuck as I never had an issue with my TDI like this. Early on it had to have a new ECU as it would not start, but never cut out when driving, it may need a bit of poking and prodding from a good independent garage.
Never heard of this before, but check operation of your intake flap motor (sits before EGR), if that is closing when it shouldn't then it will be starving the intake of air, a very long shot really.
Is it just the engine cutting out, or is there an electrical blackout too?
Does it judder and chug while shutting down?

Hi, thanks for the reply, I will try lock to lock after my cuppa and oh here lol
As for it cutting out that's all it does, it's as if you'd just turned the key off, no warning, juddering etc just cuts out.
I think all the lights on the dash show as normal including the glow plug light, will have to look properly next time it happens.
I'm planning on stripping and cleaning egr and manifold if needed so will check out the flap too.
I know it's a pain when there is no obvious broken or faulty part or code showing up.
A bit of trial and error should hopefully work out in the end
-
Just tried what you suggested, lock to lock on the drive then drove up the road and within 20yds the power steering and abs lights went off.
Thanks for the help saved a trip to VW who I'm sure would of charged me for doing it
-
Good stuff, just remember this for everytime you have the battery disconnected :happy2:
You may also have to manually 'wind' down each electric window all the way, then back up, for the one touch to work.
Hopefully an expert will be along to aid your more serious issue soon.

The window switch is faulty anyway a common issue I believe.
Would be good to find someone localish with VCDS to plug back in and clear any faults left and also turn on a few tricks that apparently can be done
-
Whereabout are you? There is lots of us on here with VCDS, search for the register (though I'm not on it and it isn't conclusive)

I'm from Hereford in the West Midlands
I've found the thread to who's got it but I haven't got pm facilities yet, looks like Smudgester is my nearest
-
Three more posts and you'll be able to PM.
Maybe an intro thread could get you there? :happy2:
-
Already done one when I joined the other day, no replies on there too :sad1:
I know what it's like when new people join the forum looking for answers to problems and once sorted never use or contribute to the forum again.
I've always joined forums to do with whatever car or interest I'm into, always found them helpful and meeting new people etc

I would try changing the lift pump in the tank for either a good clean used one or a new genuine one, my TDI cut out on me but wouldn't restart! It's a common fault with the lift pump being blocked up with oil sent back to the tank from the tandem pump on the engine that can leak a tiny amount of oil into the fuel return lines.
If you go for a used one try looking at a few at the breakers as some are dirtier than others and a clean one will be better as its not had as much oil around it.
Hope this helps.

Yea that it similar to what I have read somewhere before.
Rang up TPS today to price up the relay I thought it might be and that was £60 plus vat.
Bloke on the phone asked why I was changing it so I explained what happens and what I was going to replace inc the lift pump and he said he'd doubt it was the relay, but maybe the fuel pump relay 449 under steering column.
I order one of these instead as it was only £8 plus vat.
I got a price for new genuine lift pump and that was about £160 plus vat.
Might be the next thing I buy
-
That's the sort of money I was quoted from TPS for a new lift pump.
I went for the £40 used option.

Why did you change your pump, did you have similar issues to mine?
-
did you manage to get this sorted

did you manage to get this sorted
No not changed anything yet, ordered a fuel pump relay will pick it up tomorrow.
It's not been driven much as don't want it to cut out and be stranded but at same time need to drive it to see if it will cut out so I cam check a few things
Why have you had similar issues?
-
No nothing like the trouble you are having but did have my car eating turbos few years ago.Know how frustrating it is

Is that a common issue too?
I could go out and buy all these parts and hopefully sort it but it won't help me find out which one it was so will just change one part at a time and hope to get it sorted soon

turbos was only an issue on the first mk5 54-56plate

I wouldn't say so... Mine just cut out on me and wouldn't start again, I read up about the fuel pump problem and tested the one fitted at the time and when supplied with 12volts it didn't run so I changed for a used one to see if it fixed it and it did the job! I will replace it for a genuine new pump when and if this one ever goes.
Did you replace the relay you mentioned?
-
No didn't pick it up today as I was out of town, will get it tmrw and try it.
Fuel pump is next but might bight the bullet and buy genuine just I case the secondhand one is a duff be too, no point buying it twice
-
Update.
The car hasn't been driven much as we've had a lot on so didn't want to get stranded anywhere.
Out in it tonight and it cut out again, literally 100yds from the first time it done it!
Engine was at temp, it had driven 20 mile round trip and it died as I turned into a road.
Checked dash and all the usual lights were on inc coil light.
Checked fuel pump relay under dash on drivers side, that was ok
Checked lift pump in tank, couldn't hear it as was on a noisy road so I took top off fuel filter housing and fuel came out when ignition turned on.
Did notice the fuel filter had slipped off the top and was in the bottom of the housing and there was little diesel in housing about half way up filter off the bottom?
Turned the key on and off to fill housing and put lid back on, didn't have no gloves to put filter back on lid.
Tried several times cranking engine over but fails to start.
It's rather hot out and don't want to keep turning it over so will wait till it cools down and try again.
So I have eliminated a few things and noticed the same thing again. The filter housing isn't full BUT the pump was working when I checked after cutting out.
Could the pump cut out at some point and engine runs until too low in filter housing the cuts out?
The mrs also noticed today that in 3rd there was a bit of a hesitation when accelerating, not all the time but occasionally .
Anybody care to give a bit of advice on what to check or try now, should I buy a new lift pump in tank in case it has an intermittent fault?
-
You need reliability (new bits = reliability) so the tank pump is the best bet since the filter housing should be full - it's the most common fault for your problem.

Could the cam or crank sensor be an issue, when hot it fails causing it to cut out?
Just something else I've read?
Agree on what you say about new parts, that's why I'd rather change one thing at a time to eliminate the faulty parts
Going to keep an eye on fuel filter level, see if it drops again when it cuts out
-
If you check with TPS they'll tell you how many pumps they've sold and it will be a lot more than cam or crank sensors for your model of vehicle - also the sensor faults will show on VCDS scan.

did anyone sort this problem out ?

Any fix to this fault? i have a 2.0 tdi engine code BKD first time the engine cut out i had the car juddering before it cut out plugged in my snap on solus machine carried out fault scan and EGR Swirl flap fault appeared but was only a intermittent fault cleared that fault but vehicle still didnt start after. Removed EGR pipe to the valve and blocked the pipe using 50 pence but still no start. sprayed deodorant into the intake and the vehicle finally started after cranking for a while. As a mechanic myself i know that usually you only need an easy start if the vehicle is being starved of fuel but i have replaced the fuel pump in the tank no less than a month ago (with a Bosch pump from factors) im starting to think could be fuel fillter as im unsure when was last replaced. I also no there is a bad turbo whistle which aslo sounds like there is a leak around exhaust manifold which could be drawing in more air causing this fault of cutting out? any help would be greatly appreciated
