Apr 26, 2013 1:18 AM in response to thatbookisopenby Alberto Ravasio,You must use AHT included with the installation media that came with your computer (Snow Leopard DVD)

Apr 26, 2013 1:44 AM in response to Alberto Ravasioby thatbookisopen,Thanks Alberto.
Unfortunately I do not have the original disc to hand, however I do have a disc image of the disc, so if I copy the contents of that image to a USB drive, then reboot the Mac holding Option-D with the drive attached, will that work just the same?

Apr 26, 2013 1:53 AM in response to thatbookisopenby Alberto Ravasio,Pressing the D key is sufficient to start AHT

Apr 27, 2013 1:08 PM in response to Alberto Ravasioby thatbookisopen,Unfortunately, burning the image I have of the Snow Leopard install disc onto a external hard disc and DVD and pressing 'D' at startup did not work. Instead, the Mac just boots straight into OS X.

Apr 27, 2013 1:31 PM in response to Alberto Ravasioby Zandera (tm),Actually, that is not true.
AHT is on BASE VOLUME which build on hidden partition of system disk (shipped)
Press and hold D-key after boot up chime and hold for about 45 sec
see User Manual Chapter 4 page 57Checking for a Hardware Problem
If you suspect a hardware problem, use the Apple Hardware Test application to help determine if there’s a problem with one of the Mac mini components.
To use Apple Hardware Test:
1 Disconnect all external devices from your Mac mini, except the keyboard, mouse, and display. If you have an Ethernet cable connected, disconnect it.
2 Restart your Mac mini while holding down the D key.
3 When the Apple Hardware Test chooser screen appears, select the language you want to use.
4 Press the Return key or click the right arrow button.
5 When the Apple Hardware Test main screen appears (after about 45 seconds), follow the onscreen instructions.
6 If Apple Hardware Test detects a problem, it displays an error code. Make a note of the error code before pursuing support options. If Apple Hardware Test doesn’t detect a hardware failure, the problem may be software-related.
Important: If Apple Hardware Test doesn’t appear after restarting, hold down Command (x)-Option-D and restart the computer to access Apple Hardware Test from the Internet. Your computer must be connected to a network that has access to the Internet.

Apr 27, 2013 3:12 PM in response to Zandera (tm)by thatbookisopen,Thanks for the responses and links Zandara, however; firstly the hard disc in my Mac has since been replaced, formatted and Mountain Lion installed since the Mac was originally shipped, so I don't think that hidden partition will exist anymore, and secondly, I have executed both an SMC and PRAM reset and neither work.
Ultimately, I think the Bluetooth/Wi-Fi card has died. I have Genius Bar appointment for 29th April booked to have this looked at anyway, I just wanted to do what they are going to do beforehand.

This solves "no original HDD present" problem.

Apr 27, 2013 4:05 PM in response to Zandera (tm)by thatbookisopen,This is fair enough, but as I mentioned in my original post, when running the online version of AHT I get error 1005D, which I cannot find a definition for anywhere on the Apple support pages or the web.

Apr 28, 2013 2:22 AM in response to thatbookisopenby Alberto Ravasio,I did some test here.
I have an ADSL 20Mbps Down/1Mbps Up. My LAN connects to the Internet through an ADSL Modem/Router that has NAT and Firewall enabled.
In my experience, it is not possible to start AHT from internet or OS X Internet recovery until that computer is behind a Firewall or NATted LAN.
Errors like -1005D or other strange codes happens in such a condition.
To successfully perform those mentioned procedures I had to put the computer directly connected to the Internet, no NAT, no Firewall involved.
On my router configuration there is an option called DMZ (Demilitarized Zone), where it is possible to specify a LAN IP address that is not filtered in any way.
Hope it helps.

Apr 30, 2013 1:37 AM in response to Alberto Ravasioby thatbookisopen,Thanks for the help, however I haven't tried that yet Alberto. Went to my Genius Bar appointment yesterday and they quoted me £258 to replace the whole logic board. Told them where to shove it!
Attempting to find Mac compatible USB Wi-Fi adapters...

Aug 25, 2016 8:11 AM in response to thatbookisopenby TommyBadger,It has been my experience that the -501 0D error means that the system doesn't like the wifi network you're using. To get around it, I have used an ethernet cable to plug my computer directly into the modem.
