Welcome aboard 
Plenty of information to sift through here, but for starters the TDI75 is widely reported to be 5-10mpg more economical than the '90 in use, and doesn't suffer the eventual failures of the VNT turbo and DMF that are used on the '90. The '75 is generally considered the joint most reliable version of the A2 alongside the 1.4 petrol.
Just to note, if you're searching the site, rather than its own search function it's often easier to use Google and include A2OC in your search terms.

TDI's - 75 vs 90
I've had my 1.4 TDI for a couple of months now and love it to bits (I hope my Porsche 968 isn't reading this!) but can't help wondering what a 90 BHP version feels like in comparison . . . Would it be worth changing up from a 75 BHP model? Looking at the fuel figures on Autotrader's tech sheets...

Moving from 75 to 90 bhp
Not sure if there is a thread about this.I have owned my 75 tdi for 5 years now.I have just been offered a 90bhp tdi with 50 thous miles on the clock,05 plate.Do they suffer from any problems, gearbox, turbo, engine etc.Are they just as strong as the 75.My 75tdi has 97 thous miles on it.I dont...

Good shout For best reliability check for cambelt/waterpump having been done in the last 5 years/60k miles and if at 150k or over, ideally the oil pump chain and tensioners being done also. Expect thermostat, temperature sensor, drop links and ARB bushes, but these aren't hugely costly.
It's also worth getting an earlier car with the cast lower suspension arms as the later pressed steel ones are now rather prone to failure through rusting. Just make sure it has a fresh MOT so you know that the balljoints on the ends are OK, as they are not replaceable on those arms. Even then it could well be a good idea to renew their dust covers anyway to keep them in good shape. I think the changeover to the pressed arms was during the '52 plate. If you do get a later one, the cast arms are still available from OE quality manufacturers such as Meyle or Lemforder, and many owners on here are swapping over to them.
I think the 'sweet spot' on a TDI75 is an early '52 plate, which should still have the earlier arms but should also have the larger 42L fuel tank and the electric coil cabin heater. This is more reliable (although sometimes less effective) than the Webasto diesel aux. heater previously fitted. TDI75 engines up to about a '53 plate will also be the AMF engine, which is the same unit as the later BHC version except with fewer electrically operated bits to fail and put the engine light on.
Good luck with the hunt and don't forget to post up photos of what you end up buying ?
