CDTI cutting out
 
Can anyone help me?
My Cdti has an intermittent problem. It runs fine then for no apparent reason,
when I either put my foot hard down or just pulling away gently it will cut out.
A quick flick of the ignition, it carrys on as normal.
I suspect a fuel delivery problem but where do I start?.

Hi Nick.
If your model as an under bonnet pump then check the flow, also have or do a leak back test on the injectors, if possible find the nearest T4 to you and get a session on the car.

I had the same on a car a few years ago, it was a case of injector leakback, I replaced one injector and all was well.

My car had similar symptoms, and again it was an injector with excess leakback. I had the injector rebuilt at a Bosch place, and had no problems since :)
(Although, now I would just contact mikeyboy (? who can test these) or another trader on here and get a good 2nd hand unit for less money)

Just had car put on diagnostic reader.

P1190 rail pressure control

P1260 delivery fuel pressure monitoring

Gentlemen. Where do I start looking??

Have you got more than a quarter tank of diesel in?

chunkybray 13th August 2019 16:40

Does it on a full tank or an empty one.
I have also had a leakback test done and all injectors within limits.

HI Nick
Try taking the connector off the fuel rail and clean it with electrical contact cleaner, then my next step would be to look at the regulator O-rings, if you are reporting back that the injectors are ok, how quick did they fill up after a 2 minute tick over what mil was in each one?

Sounds to me like damage to the connector on the common rail pressure sensor, or as I found with an ECM recently, where the reading is 0, but the car still runs :eek:

Brian :D
