I thought i read they were meant to be around 1, but then again, that could have been the glowplugs

Injector 1 is the one ive just done with a second user injector, that one appears to be away from the rest , ive been trying to find on Vida to say what they should be reading but i cant find what im looking for....

Pretty sure in the test description it was +/- 3 which none of yours fall outside.
It's been a while since I did one though so I could be wrong.
Regardless, I wouldn't change an injector based solely on the correction test and would need tangible symptoms and additional data before concerning myself.
I've seen D5s with some very ropey correction test results which otherwise run perfectly well.

Im still getting a poor start, perhaps 5-8 turns on a cold start, ie 1st start of the day, If i start it in the morning come back later on in the afternoon, its not too bad, but leave it over night and its back to slow starting.

I changed the injector due to misfiring and delayed start fo the day and VIDA said sommat about injector 1 ages ago so thats the one i changed and it has cured the misfiring, but i still have the delayed start issue....

I looked at the screen priot to the test screen and found this info (see image)
Looks like i am just ok? oh, its been -2.4 on one of the tests i did

Cilinder 1 is just within limits.... but what beardaddy said over there if it starts and runs ok its no worries
If it starts bad try a leakback test and if cilinder one is excessivly leaking than you have pressure loss at startup hence the longer crank time

Thanks, 5C, I am yet to attempt another leak back test, 1st one was an epic failure, spewed diesel from the return line, was later told to clamp it, still to find sommat suitable to clamp with, I'm thinking mole grips.... :/

When I done a leak test I used a bolt, when using a bolt used the smooth shank before the bolt head and after the threads, or you could used a screw that has a shank just to block the return fuel you can always surcure with a clip or cable tie.
