injector issue (i think) 3.0 tdi 55 palte - 152k

right so i have been noticing more and more white / blue is smoke on idle i have been googling away and there are many bits of information available and some have been fantastic bits of information and some are just confusing.

i am basically after confirmation of my thoughts before i start spending £200 on injectors ( i think i need 4 Min)

i am happy to the install just want second point of view.
measuring block 75,76,77

measuring block 72, 73,74

i have found a very useful page on here or other forums regarding A8 techs description

ie first value over 45 (example 60 ) second value over 15 (example 20) are leading to defective injectors

and install information

so this leads me to think i have 4 duff injectors (two very duff - 1 & 5 as i have replaced the glow plugs last week)

i have a video of the exhaust ill upload too.

if any one can spread some light on this i would be much appreciated

thank you in advance.

thanks desertstorm, my worry was it was an some thing else, unfortunately there is no error code for this, i have made the job and trying to see if this is a injector issue by buy injectors of a low mileage car (60k ish) and swap them out the worse two to see if that cures it etc.

so has any installed second hand injectors?
