Thanks guys, both links made interesting reading!!

Especially when you consider that I'm still on my original pump on a 56 plate at 80k and asking it to deliver Evolve stage 2 fuel pressures.

Maybe this is my fix, oil loss aside (which I'm hoping is now fixed) the fuel pump might just be the obvious answer. Pretty sure they're only £250 and are an easy install!!

I've also been getting the 2AAF (fuel pump plausibility) code for months, although a lot say that is to be ignored and isn't hpfp related.

Could dying hpfp cause black smoke on start up?
