2004 cdti cutting out
Morning folks
I am having a problem with my cdti It’s starts ok but when idling it will cut out and then it won’t start again. It doesn’t have the ubp If I sit in the car I can hear the Itp running, but it keeps running for over a minute then I hear a click from behind the glovebox and it will start for a while then cut out again. Does this point towards in tank pump. Car has 123k. Thanks Thomas Sent from my iPhone using Tapatalk

The in-tank pump on the facelift cars is pretty reliable. I suspect your ECU might have had a swim at some point

Your ITP will run all the time the engine is running or ignition is on. Otherwise how do you think the engine stays running? The clicking you hear is likely to be the fuel pressure relay, if you drop the cover from below the glovebox, you will see the fuse box. With the engine running, feel which relay is clicking, and switch off engine, remove relay and check the contacts are clean, then replace..
Before doing that, check your plenum chamber is dry and clear. Read this thread, and you will see how to do it. The main E c u sits in here, and if the plenum drain is blocked, the chamber fills with water, and if it gets in the e c u, can cause all manner of issues. If your ex u has got wet, send a pm to member Marinabrian, who can repair them.

It doesn't run continuosly with just the 'ignition' on though Rich - 30 seconds to a minute, depending on which ECM is fitted then it will shut down, but will start again if you then crank the engine over.

Ecu is totally dry. The car has been parked up for a while and I did let the fuel tank get under a quarter just by starting it up every few days and letting it run.

The quarter tank syndrome isn't relevant to your car as it doesn't have a UBP.
When the car stalls, does the ITP keep running? If not then either a faulty fuel pump relay, a wiring fault between the relay and the ECM, or a fault with the ECM itsef. If you try and restart the car does the oil light come on with key to position II as it should? If you have an automatic, does the IPK display still give the gear selection, or revert to EP? |

Hi mike at this moment in time the car won’t start at all. The oil light is working as it should. It’s taking 70 seconds until fuel pump relay switch off.

When you try to start it, does the Rev needle move?

The car was running grand until I fitted an in-line thermostat. Don’t know if that’s relevant.

Try easy start ? Also, you haven't dislodged the wiring for the map sensor? Or any other for that matter? Sent from my SM-A310F using Tapatalk
