   Got myself another Saxo diesel 02 plate with the Bosch pump and it's a cracking motor, new axle fitted and running a treat on B100 but there is a problem and I don't know what's causing it.
   
   Car starts fine from cold and runs fine, but start it from warm and for whatever reason it revs it's bollocks off (as if choke is full on) and does so for about 40 seconds then it just revs down to normal 800rpm?
   
   Changed both filters, fresh oil, glow-plugs, ran cleaner through the pump and injectors (it soaked for 2 days) running out of things to try....
   
   Any thoughts?

   Yeah system was bled so the problem isn't air?

   Check for air leaks sounds like theres air somewhere in the system causing it to rev high mate.

   Really? An air leak would cause that problem? I always thought an air leak would cause rough idle..

   It can cause both rough idle & high idle mate.
