Cuttting & plumes of white smoke (Diesel?)

[Poodle]

Fair enough, yeah i believe third is the first gear with full fuelling. What's confusing me is the cloud of white smoke - the reason it cuts out is because the ecu stops play when it sees rail pressure drop too low, ie it stops firing the injectors, so where's the diesel coming from to cause the smoke...? I guess if the injectors are leaking enough at high rpm, then maybe that could cause both the drop in pressure and the extra fuel in the cylinder.

Afraid so, hence why i always recommend refurbs over scrapyard/second-hand jobbies.
