I have a transporter T4 888 special SWB 88 on a 52 plate.

After having the engine management light come on the vw main dealer diagnosed the main problem to be a

No4 Needle lifter jet faulty.

Im thinking of doing the job myself but I'm hoping for some advise on the matter first.

the engine is AJT 2461cc

can anybody tell me what parts i will need and recommend where to get them from?

also how do i locate No.4 ?

Thanks

Hi mitton

im a bit confused when you say about pumps?
the main dealer i went to quoted over £600 for the job.
i was under the impression it was something to do with an injector?

Changing injectors isn't terribly difficult. No.4 injector houses the needle lift sensor that tells the ECU the rotational position of the engine so it knows how to adjust the injection timing. No.4 injector has a cable attached to it as well as the injection and bleed off hoses. Check the following "how to" thread for more details:

Cheers for your help mitton, the van runs fine most of the time and the engine management light sometimes doesn't come on for ages (months). I know main dealers are greedy but going on you paying £80 and them quoting me £600 i would guess at the problems being completely different. fingers crossed though i hope I'm wrong and i can get this sorted for under a ton.

Cheers mate

Before you do anything, measure the resistance acrross the pins on the wire.

If its 90 - 120 homs then your injector might actually be ok.

Hi NiSk

thanks for the reply

I have read that one and will defiantly be following it if it turns out i need to change the injector.

You say the needle lift "Sensor" is No.4 which is a start but the main dealer have said its the needle lift "Jet" any ideas on what this is and where it can be found?

cheers

Hi Rake

sounds easy enough to do but can you give me a little guide on how to do it?

The needle lift sensor is built into the injector body of no.4 injector. If the fault is only occurring occasionally it could be either the sensor or the wiring to it. First do as Rake suggested, Find the connector where the wire from the injector plugs into the harness, separate it and measure the resistance across the connectors going to the injector with a multimeter set to ohms. Try wiggling the cable around and see if the value changes, if so there's a break in one of the wires. If the resistance is outside the range or the value changes when you wiggle the cable, change the injector.

If it does turn out to be the injector you'd be well advised to have them balanced at the very least.

Give me a shout if you need any help.
