I Have A Duff Injector, How Do I Track Down Which One It Is

[pjwpjw]

as per title, PD 1.9tdi engine, one duff injector shown by an engine knock and on vagcom. knock disappears on overrun when the engine cuts the fuel.

 

vagcom shows 01 engine - 023 injectors:

 

19 - 35 - 34 - 36

 

So i presume the one with the lower fuel flow is at fault. How do i work out which injector this is?

Hi pjw

 

I am not a expert, but if that is the case I would say it is cylinder one, and that is where the belts are, but

you don't say what the mileage is, but if one has gone down I suspect that others will fail, so I would replace

or have all four reworked.

This thread is surplus/duplicate - answer is is in the "Diesel Engine Started Tapping/rattling" thread (bolt sheared in injector camshaft bearing holder)

yep, certainly is. in this case anyway it was cylinder 3. *or third from left if the sequence is different.
