Hi Thanks for your reply
My diesel is quite high millage at 103000
I have the fault code P0243
which reads as Turbo/Super Charger Wastegate Solenoid 'A' fault.
I reported this on my first post to the forum about 6 week s ago.
I have been told that the Solenoid is actually the actuator on the turbo and it most likely that the diapram or spring has gone fault inside the sealed actuator, rather than anything else on the car.
I have a new actuator but the two actuator bolts "will not budge", I have put some penetrating oil on and will give it another go at loosing the bolts but access is really tight.
