Well if its going over 230Kpa it IS overboost - that has to be a physical fault with the turbo/wastegate etc if you are running with the boost modulator solenoid out of the circuit.Try disconnecting the wastegate and jam it in the open position then do some live data - see what it gets up to then.

Mate, I have a TD5 110 2001. It's doing my F....ing head in!!! Yours sounds a lot worse though.
Hope someone gets to the bottom of it, I really do. Wish I stuck with my 200tdi, never had any problems...

Ive got a similar issue with a TD5 Defender (2000), Ive tried a few fixes and have fitted a boost gauge to assist with elimination process...
Do you guys have a snorkel fitted by any chance?

i had the same issue with my 2001 disco, in the end the wastegate disc had got sloppy on the arm inside the turbo and caught sometimes. i looked to get it sorted and needed the car on the road asap so bought a brand new one.
sorted my overboosting out straight away.
to remove the turbo is really easy.
3 nuts/bolts on the heat shield,
3 nuts on the turbo to manifold,
3 nuts on the turbo to exhaust,
1 on the oil feed,
2 on the oil return.
about 30mins - 1 hour to remove
