Right. The black wire is actually not required, the signal ground comes from the 3-pin connector.
Does MES really see your adapter? What does Settings-Interfaces-Scan for interfaces tell you? (I use MES 3.0)
In Setting-Interfaces, do you see interface type "K-Line/VAGCOM"? What COM port is assigned to it? I have COM4 for example.
Have you tried connecting to engine ECU instead? It has same 3-pin connector, located on the right side of passengers footwell. First position on the adapter switch.
As you try to connect, do you have the ignition on? The key must be in last position before starter kicks in.
If everything checks in but still no connect, check for bent pins in connectors. It must work.

I have now disconnected the black wire and still the same
Using multiECUscan v4.7, I have full ability to scan for interfaces, but, it finds nothing
The COM port has been setup in every possible way using ports Com1 - Com8 and everything does the same
The switch on the adaptor has been tried in every position & I am back to the connector under the dashboard which is where I believe it should be
When I run the test of the K-Line / VAGCOM, I get this...
VagCom/KKL
Testing latency with 200 bytes of data...
The operation has timed out.
I am about to give up!

The yellow cable under the dash with the 3 pin adaptor is what you should focus on.

That is the one I have been connected to most of the time, briefly tried the one under the bonnet, but back to the one in passenger footwell
You can try this temp fix until you sort it. Solder two works from ABS lamp to airbag lamp then insulate airbag lamp from its connections in the socket. It worked for me.

I might end up doing that tomorrow!
However, I will have one more go, so want to check the settings
Yellow connector under passenger glove box
Serial port setting 14400bps, latency 1, com1
4 positions on the OBD plug, should be at 2nd position, labelled 3
Connect to car with ignition on, but engine not running
Connect via MultiECUscan - auto detect should see it
If that is all correct, I have tried it loads of times without any connection being successful
If I get a connection, run trw2scan in a dos box and clear errors, presumably it shouldn’t keep getting timeout errors
If I don’t get connected, will pull the dash apart and do the temporary fix so that will not fail the MoT, but, I don’t know if it will fail on anything else, so still fingers crossed

Well you time is short now so best of luck.
That said have you checked here: https://www.fiatforum.com/multiecuscan-members-register/ for someone near to you who may be able to help (probably post MOT now)
They may have no more luck than you (if your airbag ECU is toast) but at least you will get some sort of confirmation etc.

Normally MES should be able to find an interface connected to USB, and choose the corresponding virtual COM port for you.
If it's not the case, chances are the USB-COM driver is not functioning, or is not installed. With driver properly installed, plugging USB connector into computer should create a new COM port in Ports section of Device manager (if using Windows of course).
If some "Unknown device" is created instead, then you need to install USB-COM driver from the CD that came with adapter.

Definitely was setup as a com port, I use serial communication for some work stuff, so am not new to serial port setting up, but this one seems to have beaten me.
If I can get it through the MoT, then I will happily take it to someone to have a look at, but until I get the MoT, I can’t go anywhere in it
Mot in UK seems to be dead serious.
Down here, you can fail the mot and still legally use the car for some time, unless it is a dangerous failure such as brakes. Then you fix it and have second try, free.
And you can drive around without mot, if caught you say you were driving to the nearest mot station (which is allowed).
And if you have airbag light lit, you can always say i know i know, but look how cool this car is, and then you pass if important things are all ok. Year after year I pass with non-existant rear brakes and a good chip on the windshield, just because the car is so cool.

As the car has been off the road for over 10 years, I have no grace period, normally, you can put a car in for an MoT a month before it is due and then if it fails, you can still drive for the Month
You also cannot get away with saying you are on the way to an MoT centre as if you do not have an MoT, you have to have proof of a pre booked MoT to drive it there and it still is questionable if your insurance is valid
Fortunately, the centre is only 2 minutes down the road from me
I am hoping for a friendly tester who may be a bit lenient, but do not want them to pass it if there is a major issue

Out of curiosity, does anybody know why some of the bulb holders are black, while there are blue red and yellow?

The yellow one is for the air bag light that is giving you problems, the others without looking on the opposite side (face side)of the instruments I'm not sure. I don't know why separate colours were used other than for quick identification of problems by Fiat garages.
OP
OP
Temporary fix done for the airbag light
Did all the obvious checks before the MoT and then discovered the horn wasn’t working
Checked the fuse and relay, they were fine, realised it was 30 minutes before the local car spares shop closed, so dashed down there, got a horn for £6 bolted it to the radiator mount and connected it.
I have now done everything I can so need to see what the MoT brings
4 new 205/40/17 tyres being fitted at 9am and the MoT at 12, so will be sweating all day tomorrow
Gonna be a long day!

Fingers crossed. I’m sure you’ll be fine.

The wheels have been on it for many years and I know it has been through a couple of tests since they were fitted, so no option than to fit new tyres to them
It is now at the test centre, so will find out this afternoon how it goes
Gonna be a long day!

Regarding wapper's comment about 17inch wheels, France and Spain will not allow for any modifications to a vehicle at the technical / MOT test. including wheels.
