Boost 0.3bar max
Discussion
Gents, I know this issue has been covered a few times but unfortunately all the pics & links are dead.
When driving yesterday, after replacing and recharging the air con condensers I was on a nice stretch of road and decided to check my boost pressure as I plan on fitting some mods soon. Anyway I can only get it as far as 0.3 (it was a long straight) no matter what I tried. Going by the reading I've done I'm thinking stuck waste gate or faulty N75. Is that still the consensus of opinion and can someone please send me some pic/guide of how to check or replace these items.

I would say that you are looking at a 75, or ECU issue.
Even with 1 turbo operational, you should be able to see more than 0.3
To do a quick visual, jack the back up and have a look at the actuator rods. Near side has a greater tendency to snap than the off side. If snapped, check the gate movement too.
If rods are good, you could try disconnecting them to check the movement of the gates.
If all is ok under there, probably time to get it plugged in.

Limt mode??
Sticking actuators usually gives overboost as they are stuck shut (the position they are in more of the time if not in use or town use)
Agree with others N75, MAF or Limp due to boost leak
I Live in Banff and ordered a PIWIS (or whatever its called)but not arrived yet, or you could easy had a shot.
Standard Actuator springs are around 0.4 bar of boost.
A simple code reader will tell you if limp more or N75 fault.
