cheers, is it easy to remove and i have read the electrics gets full of oil and should be cleaned if so what with and isnt there a risk of damaging the electric

It's easy, esp. with egr etc removed. Carb cleaner & rag should do job. The function of the TVB on the cdti's is to stop engine over run when switching off so I wouldn't touch the electrics unless you have an issue with this or starting issues.
