2.0 Hdi (diesel) cuts out at random.

[Wrinkly57]

Ta very much! Reading all the posts here seems to be pointing me in the direction of the LP pump.
It's a 110 by the way. So far as a fault code is concerned we'll see what comes of the local independent
having a look with his trusty code reader. Wiil let you know when he's done and hope he doesn't charge too much. Any ideas what is the best and cheapest code reader to buy?

Easy way to tell that the pump is failing is that it will sound low and grumbly when you first set the key to 'ignition'.

You problem though could be an electrical glitch somewhere though? a decent code read should help narrow it down but it's not something we could say was common here

P.S. love the "Wallet Attack" comment

Double vision? Looks like you've found a new way to bump your post count up again Welters

Bugger - I remember double-de-clicking but thought I'd got away with it (it used to warn you not to post 'so soon' after the other).

Hi chaps read posts on car cutting out,mine as done the same about a dozen times.
Have had the car allmost 5 years 104.000 on clock well serviced runs sweet as a nut when it as a fault reading it comes up open curcuit injectors open curcuit glow plugs.The last reading it said cam sen aswell,when it does cut out it starts ok and drives perfect the engine light stays on till next day then goes out.It as had a new HP pump oooh painful it had been cutting out before this was fitted and after at random.After reading the post by springnut I have fitted a new multi function relay today see if this works cheapest option, Pug machanics know Idea there option new loom £500 new ECU £500 Any suggestions I would be greatful
cheers basher

New HP pump? what was all that about?

I've just remembered that mine cut out once for no reason and my mechanic said it would be the crank sensor shutting down the injectors (ecu thinking the engine was not actually running ).

Could be worth a checking out?

Hi welton the only time it let me down was when the high pressure diesel pump went west.
But I will try the crank sens thanks for info nowt to lose fingers crossed.
cheers basher
will keep you all posted on progress

Hi Wrinkly57 - sorry to hear of your problems with the car. I bought a generic OBDii interface which plugs into a laptop. I am glad to say that it has never been used in anger. It does work to a point ... connection seems to be only average. You can get the interfaces from 99p plus £16 postage or so from the far east on eBay - or a bit more from a UK dealer (who I guess imports a dozen at a time for 99p each!). Changing the double relay is easy and cheap, so perhaps the only piece of diagnosis by random part replacement that is worth doing. All the various sensors seem hard to get at.

Hi basher - Your symptoms are different to mine - in that I got no engine management light coming on, so I guess the relay will not help - but having done it you have also checked the battery terminals and ECU connections, so removed three possible causes. I would be interested in crank sensor cleaning procedure. I think there are three sensors which can give trouble - crank sensor, cambelt sensor and HP fuel sensor (which is more or less impossible to change so means a new fuel pump) - but don't quote me on this please!

Regards and best of luck to you both!

Springnuts.

Hi springnuts
Thanks for Info,Have changed cam sensor cleaned crank sensor running sweet as a nut (excuse the pun)
Just hope I've solved it, will let you all know fingers crossed.
Cheers basher

Hi all car running sweet at the moment 700 miles not cut out fingers crossed. Replaced cam sensor and a new multi function
relay Its 110 exec HDI 140,000 on the clock
Thanks too all for info

Hi All, Many thanks for all the help in your posts. Sorry it's taken so long to come back but very busy and here's the story
since the car misbehaved on Nov 8th. Took it to the local independent who did a diagnostic check and reported the following
codes:- P0606 ECU Defect and P0380 Glow Plug Relay. The glow plug relay fault code was caused by me a week earlier when I fitted new glow plugs and forgot to reconnect the power supply! When I cranked it over, naturally it wouldn't start and obviously recorded this code. (I did say in a previous post that I am the village idiot - do you believe me now?)

The second code is a mystery. It would seem from the other posts that it's possibly an intermittent power supply fault (maybe the relay near the ECU), not the LP fuel pump as I first thought,but since that diagnostic check and the clearing of the codes it's run faultlessly, not missed a beat (except for the airbag light coming on from time to time when my wife moves the seat after I've been driving it, so when I get the time I'll carry out the oft suggested mod to the air bag sensor wiring under the seat or when it becomes too irritating!)

So there you have it. One other matter worth mentioning is that the day before this fault occurred, I washed the car and hosed it off, and during the journey when it cut out it had been briefly raining hard. Last week when looking under the bonnet (I do this from time to time just to reassure myself that nothing is about to fall off) I noticed that water was collecting at the bottom of the battery tray but couldn't see form whence it had come. On the other side where the ECU is-bone dry! Is there a possibility that this fault is water related? Who knows, Who cares? Going to take some more tablets now and lie down.
Byee!

Interesting thought. Do you still have the engine bay undertrays? I had to rebuild the ones on our car as they had been ripped off and damaged when the screws corroded. (I need to do more on this now as one of the replacement fixing screws on the front one has corroded; also the centre fixing - a cross head screw, however not the original fixing, has corroded so the last people to service it just tore that part off the tray! But it occurred to me that it would be easy enough to leave them off - however this would allow spray to collect inside the engine bay and cause all manner of problems. Regards, Springnuts

Nether of mine have undertrays and, according to Service Box, that's how they left the factory.

Pour seulement des rosbifs, n'est pas?
Ils sont tres deficile, tres amusant, c'est magnifique!
