Quick question: Could a leak/fault in the VNT system cause a poor and smokey start? Car always starts from cold but after prolonged cranking, fires nearly straight away when hot. The vehicle also smokes a bit when putting your foot down(under load/in motion), especially when you are in maybe a gear higher than you should be.

A little info: New higher rated battery, new dedicated earth from starter body to batt., EGR delete + remap, swirl flaps removed.

My only other concern is the cranking speed which isn't all that impressive despite the above^ Starter?

Fair enough, bit more info is the engine management has no faults on it...

It's got the Fuchs 5w40 stuff that Autolusso sell in it

Did we do the EGR & swirl flap delete??

Again more info I forgot to add glow plugs are new and all have feeds supplied.

Ned you did the EGR delete/remap. I did the swirl flap delete, just took the actual flaps out and left the rest as it's the CF4 variant didn't think I'd have issues with boost leak. Vehicle is fitted with FMIC and de-cat down pipe too.

The car went back to Autolusso to have the map tweaked as it was idling poorly and that was after the swirl flaps were removed so I guess it should be running optimally as far as that is concerned.

A poor idle and extended cranking time sounds like an air leak to me. Added to that you have smokey running, which is when the air leak becomes a boost leak.

Neither of those things should affect the speed which your engine cranks at, that is related to battery, condition of earths/power leads and the starter motor itself.

Thanks everyone for all the responses. Oil cooler started leaking a couple of weeks back so as I was fixing that I took the opportunity while the bumper was off to get some gas leak detector on all the silicone pipe work and joints but couldn't find any bubbles. Might be a leak from the inlet manifold gasket I guess.

A new job as meant the car gets used a lot more and the starting speed is improved somewhat which makes me think it was just a bit low on voltage and coked up from short trips.
