Silly mileometer moment:

Unfortunately the alarm/central locking has shit the bed
The remote fob has stopped working, and now it sets the alarm off every time I unlock the driver's door.. it's a right game getting it to disarm, I'm hoping it's just a dead battery in the fob
I'm dreading it's something more than the battery in the fob though, sometimes the central locking operates from the key in the driver's door but sometimes it doesn't 
Joy!

Had this twice, and a reseat of the battery brought it back to life

Ah cheers, if that's sorts it I'll be happy as Larry! I'll do it when at home though to avoid getting stranded if it goes totally senile 😅

Alarm foibles sorted, the remote fob was previously taking a couple of attempts before locking/unlocking, and then it stopped working altogether the other day, followed by the alarm going off every time I unlocked the driver's door with the key. 

I disconnected the battery as suggested by @fatharris and thought I might as well check the batteries in the key fob while I'm at it. They were a little low at 5.9v (2x CR2016 fitted) so I put a pair of fresh ones in which were about 6.5v. 

After reconnecting the battery, the fob now works on the first press of button to lock/unlock and no more alarm chaos. Nice easy fix! 

I was in the mood for some tinkering so did a smoke test to check for any air leaks in the intake system as I suspected there may be something as it seemed to be a little bit hesitant at times and I had only ever seen the boost guage get up to around 10psi. Turns out it had a huge boost leak from the flange between the turbo and the dump valve! 

Took the dump valve off to inspect

I found the sealing ring had gone flat so it wasn't able to maintain full boost pressure! 

I made a slightly crude paper gasket for the low pressure (induction) side, and reassembled it with some RTV and a new o-ring for the high pressure side. It looks messy, but:

It's functional! It now holds enough pressure before the smoke starts to escape via the dump valve itself which is fine. 

Went for a quick test run and I'd say there's a significant improvement, boost now reaches 14psi if I boot it, the air leak noise I heard under acceleration has gone and it now seems a lot more responsive and builds up boost nice and quickly from a lower RPM than before. It now starts to pull from around 2100-2200rpm whereas before I was noticing a bit of hesitancy before it started to boost around the 2600-2700rpm mark. 

Another free fix, and it's made a vast improvement to the car

Ah decent, I only ever had 11psi max out of it!

Great work rescuing this one. Sounded really good when i saw it at Torque Moto in the 8th of March. Keep going!
