See this on filters going black and from there is lots of reports on this condition

I finally solved my problem, it was a faulty lift pump in the fuel tank. The biggest issue in diagnosing it was the fact that it worked some of the time, leading me to believe it wasn't faulty and VAG-COM couldn't spot it. In the end, I bit the bullet and changed it anyway (such a simple job, takes 15 minutes). Eurocarparts had a discount running a few weeks ago, so it was £128, which in the scheme of things isn't too bad I suppose. Much better than throwing it over to the main dealer.

Hope you solve your problem, don't rule out the lift pump - even if like me you get it out and bench test it, when I did that it worked - very odd. Maybe it doesn't lke cold dark places. lol

Very similar problem that I'm having with my MK5 Golf TDI (105bhp) 57 plate.
Got the AA out and the diagnostic came up with speed sensor fault i.e. the crankshaft sensor was faulty.
Changed the crankshaft sensor and also changed the fuel filter (which was black) and the engine now starts up with no problem. However the car can't go forward for more than a few yards before conking out. However - no problem going in reverse. Engine runs fine.
Got a VW mechanic mate of mine round to run more VAG-COM diagnostic checks. No problems detected. He suspects its the fuel pump as he mentioned my comment about the blackness of the fuel filter.
He is coming round on Sunday 10th Nov to run another kind of diagnostic check using a sensor that detects fuel pump problems.
Will keep you appraised.
Thank Gawd I have my trusty 1995 MK3 Golf VR6 to use in the meantime - that car is bulletproof. Never had any problems like I have had with the TDI.

Just to follow up on this - it was the high pressure (vacuum) fuel pump that had failed (Part No: 038145209Q for a BXE engine) Cost £428.72p from VW TPS in NW London.
My mechanic mate fitted the pump for me.
Problem solved.
Very relieved.
Hope this helps any other MK5 Golf TDI owners with similar problems.

And another follow up to this.
2 weeks after having the high pressure fuel pump replaced - the car ran perfectly until last Sunday morning (15th Dec). On the way to play squash and the car started to run very rough and stuttered to a halt.
Got the AA out and they managed to get it going again. Luckily I was only 2 miles from home. Engine continued to judder. Managed to get home. My VW mechanic mate came over and did a diagnostic check.
Fault codes that came up were to do with the camshaft sensor and the inlet manifold flap. Managed to get the parts from VW TPS in NW London

Camshaft sensor (Part No: S03G957147B) £93.50 (inc vat)
Inlet Manifold Flap (Part No: S038128063L) £347.60P (inv vat) Ouch!!

Parts are being fitted today (21st Dec)
I'll report back if this eventually solves the problem. I'm beginning to think that the BXE engine is just a poor engine with a built in "sickness".
Looks like this TDI will be my last ever VW vehicle.
Honda, Mitsubishi or Lexus will be my next port of call for a car.

So the inlet manifold flap and the camshaft sensor were replaced on 21st Dec.
Unfortunately the problem still persisted. Fault code still reading that it was the camshaft sensor.
Transpired that the new camshaft sensor was faulty. So we got another one from my mechanic - fitted today 28th Dec - and that appeared to have solved the problem.
Will report back in a couple of weeks to confirm that the repair is stable.
In the meantime will have to take the other camshaft sensor back to VW TPS for a refund.
What a pallava.

Hi all
i've been looking at all these threads because my 2005 tdi vw golf has been having issues with starting right from new. To start with it was just chunky and heavy starting. The dealership admitted that it wasn't right but could only come up with new battery needed, ha ha, I only fell for that once. Eventually it got worse to the point of having to turn the key off and try again. And again. And again. Sometimes it did sound like the battery was dead. But then next time it would be fine. But the battery testing showed it was ok. After reading a thread here on getting the earth checked, I did that. Actually got a new one added but no better. Finally took to another garage where the mechanic (old school, no computer) to the starter motor out, took one look at it and got me a new one in. My god , that is the first time in its entire life that car has started so well. First time like a normal car should. Thought you might like to know 😏

Thanks for your reply to my earlier postings...

In regard to the problem with my BXE engined 2007 Golf TDI - the problem has apparently been tracked down the a faulty "Impulse Sender magnet". I thought that was a fancy term for the camshaft sensor but apparently it is something different. My mechanic changed it over and the car appears to now start and run properly. I've not had a chance to take it on a long trip but hope to do some short trips around my locality to give it a good shakedown. At least that way - if it does pack up again - I won't be too far from home.
In all I've done the following over the last 5 months.

1.) Changed crankshaft sensor - car ran well for a few weeks and then started acting up with the same engine judder and stall.
2.) Changed High pressure fuel pump. Car ran for a week or so and then the same problem came back.
3.) Changed camshaft sensor and inlet manifold flap sensor. Car ran okay for 2 weeks and then just after Christmas 2013 it developed the engine judder and stall.
4.) Full electrical system diagnostic carried out and no problems found. Changed the impulse sender magnet. Car starts up and runs.

Now to see if that has finally solved the problem.
Spent just over £1k in parts and labour - luckily I have a mate of mine that is VW Mechanic. Shudder to think how much VW might have charged for similar work.

Got to say that I'm not overly impressed with the reliability of the recent VWs - so much for the myth that diesels are more reliable.

[MsChief]

did you ever get this problem diagnosed or repaired? I am having the same problem, but it is a lot worse.

[MsChief]

did you figure out what the problem was?

[utopiaplanitia]

did you figure out what the problem was?

Yes! As mentioned in my last posting on the subject - my mechanic changed the "impulse sender magnet" - that is what he referred to as being the problem. The magnet piece apparently starts to crack and breakup and that is what causes the problem. So the enging isn't receiving a proper signal.

Car is running perfectly now.

If you are based in the UK and the London area I can always get him to give you a call.

Hope that helps.
Good luck.
