300 TDi vacuum pump is a naff unit and known to fail, also costs about 109 quid to replace, buggrit.
Faulty servo, even with the engine switched off, the servo should maintain enough vacuum to give you a couple of presses before it goes hard.
If it goes hard at idle, it just means the pump cannot keep up with the leak unless you rev it.
thanks for the reply when you put it like that it does make sense he ho its off to john craddocks web site

good point.
or the pump's on it's last legs. Discos take a LOT of stopping with no vacuum.
