Hi does anyone know what figures I should be looking at getting from 2.5 di turbo engine compression test? And what the lowest acceptable figure is? I know there should be no more than 10% difference between cylinders but what should I be getting? Thanks

So if what chug says is correct then we can assume that 245psi with no oil in the bores and 280psi with oil in the bores is definitely too low. Highest reading I can get is 300 psi with oil down the bore and there is definitely 10% variation on the cylinders

I still cannot find any info to confirm or refute that figure, even had a search with no luck so maybe I dreamt it but it sounds similar to other diesel engines, and with your low readings and if there is a lot of variation between cyls then it's probably poorly.
