My boss has a bentley continental gt that has a certain issue with starting so to describe it i will do my best
The car cranks and fires but then dies it does this around 3 times before settling down and runs on tick over
When I had a look at the car for him I noticed that one of the breather flaps wasn't opening (little round disc about 6 inch into the exhaust tip) also at the same side but under the bonnet at the front when reved their was a bloom of white smoke which then settled once the car was warm
My first thought could of been the fuel pump but now I'm wondering if it's the sensor attached to the exhaust flaps
As a side note there are no warning lamps on the dash other then tyre pressure
Has anyone else experienced anything like this or diagnosed the issue and fixed it.
Thanks for your help in advance.

You really need to get a proper code reader on it rather than guessing. Only then if there are no codes should you start to think out of the box.
But even then I would be trying to look at the live data during the failed cranks to see if fuel pressure builds etc.
It could also be a combination of issues. From what you say it could be vac leak, evap valve, leaking gaskets etc.

But the white smoke is also unusual, so you could even have a cylinder filling with oil / coolant overnight..... eek.
