Found one of your posts here. https://www.the75andztclub.co.uk/for...64&postcount=9

Hi Ben.
I doubt the Hulk would move the valve, i have tried lots of times, even putting it in a vice, but as soon as you get vacuum on it then it will move, so do not worry to much, once you have cleaned the EGR manifold out, and wiped the MAP sensor, and its all back on the car, rev the car at 3000rpm for about 20 seconds take foot of pedal and you will hear the EGR change tone.
No point in just cleaning the EGR on its own though the manifold & MAP need sorting out as well.
Change the PCV filter also at the same time as doing the air filter, change the fuel filter if not had one in the last 2 years, check all the vacuum hoses from the EGR and the solenoid for any chaffing or splits.
Plenums are most important on a diesel more so that a petrol version, does it have an under bonnet fuel pump, if so is it quite or noisy, if under bonnet pump present do not let the fuel go below the 1/4 mark.
