As above car will sometimes die out when slowing down . Revs drop completely when pressing the clutch to slow down
What could be the cause? ?
Will start straight away again either with the key or if still going fast enough by bump starting it
 
Check all the obvious things like intake pipes, boost pipes etc

Also ensure the inlet manifold is nice and clean and that the flap is moving nice and freely

Are there any diagnostic errors?
 
Everything has been cleaned an even a known good egr valve has been put on also. No lights on dash. Goes great for days then just stops
 
I've never seen this particular issue on an ICTDI yet. Sounds like some sort of fuel/air starvation.

You sure it's not an electrical problem such as loose battery terminal or a bad earth?
 
Not sure but it's very strange. Will only happen when slowing down and pressing the clutch where the revs drop to 0.
Revs seem to drop very quick when it happens.
Could it be a tps? As I have idle hunting when cold and also the 1 500 rpm miss

I'm thinking of trying a tps
 
Thought it was a petrol hence the IACV valve. Ignore that one.
As Farad says - does seem a strange one - not heard of this symptom before on the ictdi.

TPS issues tend to be jerky acceleration and you should get a fault code if it is faulty but can be intermittent

I thought it would be the EGR valve - but as you say it is confirmed working then it should rule that out
 
Update. Got it put on computer last night. Injector 1 is playing up so doing a leak test tonight to see if I have found my problem
 
Cool, yes sounds like fuelling.. keep us posted
 
In what way can 1 injector cause the engine turn off?

Any injector that is misfiring can cause the engine to lose momentum and shut down. Remember his problem is an intermittent one.
 
Only getting a chance now with work but leak test was done and turns out number 1 2 and 4 are all causing problems. Time you replace I think
