Here are the VIN number
****203 is VW Golf 64 plate
>
****391 is VW Golf 61 plate


Model year is best decoded from the 10th VIN character:

... by cross-referencing it with this:

It often happened to me that the pins in the OBD were loose. In most cases, this cabal helped me, The pins are slightly thicker than in the VCDS :

That's normal in the UK, positions 4 to 6 show as ZZZ on VW's and Audi's.

This is great thanks a bunch.
Just one question, bearing in mind the location how will I be able to get to the port ?
Hi, you may have to loosen that lower dash panel to gain access; keep in mind that there are some bolts on the side behind that side fuse panel and along the bottom.


Try this link, you may need to copy and paste; the “U” tab on the top of the pig -tail, when depressed will allow the port / dlc to be released from the panel.
See two pics.

Right now I have an update OF SORTS
I have now purchased OBD II Female J1962 Replacement Connector with 16 Female Wire Sockets.
See the link below.
OBD port
Just one question it is very hard and I mean very hard to push the HEX-V2 into the port.
From the purple end of the Replacement Connector to a line on the connector is 10mm and on the HEX-V2 just lifting the tang.
Having never fitted one of these before is it supposed to be like this ?
I really don't want to force it too much in case I bend the pins in the HEX-V2
Can anybody please supply a potential workaround/solution please ?
I am not going to start on this project replacement till I either get a solution here or via Google

Doubtlessly made to exacting tolerances of the finest Chinesium.

Have you actually determined that the OBD-II socket itself is the source of the problem in this car?

Had to look up "Chinesium" and the answer is "yes" :thanks: :thanks::thanks: BUT to test it further I went upstairs and got a hold of my steamroller:eek::eek::eek: and ran over it once more for good luck, I can't do it any more because it has dented the roller:thumbs: but the plug is still intact.🤣

As the connector guy at RT, it should not be very hard to push our HEX-V2 into the purple connector. Snug? Yes. First time harder than the next? Often. But very hard? I'm picturing your punch being required to seat the connection. That should not be.

One time, connector adapters we had made failed our inspections. On examination, the molding compound on the connector had been injected into the pin contacts. On those we could not seat the connector and we rejected the entire batch. Mind, the only way to find the problem was to destroy the female connector by cutting it open.

Unfortunately, I think you have a quality issue with the Chinese vendor.

As regards the plug & socket situation this is what I have found and the action that I have taken
New harness
34.00mm

>
HEX-V2
i/d
32.32mm
37.65mm

>
PINS 1 to 8
pin 2 to pin 4 9.2mm
pin 2 to pin 5 12.65mm
pin 2 to pin 6 17.32mm
pin 2 to pin 7 21.11mm
>
pin 10 to 16 21.56mm
One reading here just for orientation
All these measurements are taken to the o/s of the pin.

Because I took these measurements I marked them with a pencil (remember those pencil things) from where the new female was going into HEX-V2 it was a 3mm gap and there is a 6mm tang so my theory was if it is already located on the pins (hence the measurement) it will not do it any harm applying firm but gentle pressure and it went in, tried it again and now its O.K.

I have now done my testing using my DVM
>
Pin 4 to battery negative post = 0.00 v
>
Pin 5 to battery negative post = 0.00 v
>
Pin 16 to battery negative post = 12.71 v KOEO

As much as it pains me to say it I now need help.
Can anybody send me a p.m with a view to getting this sorted out just the Ross-Tech stuff.
For their troubles, I will pay the hourly agreed rate plus mileage, plus I will supply lunch and any amount of tea or coffee as desired.
To be fair I do not want any D.I.Y enthusiasts, I'm sure that you can understand.
Once the job is finished I will transfer the amount into your bank account usually within two hours
Once resolved it will show resolved on here with/without the person's name as per their wish.

Imgur.com will let you upload short videos.

-Uwe-
I'm the U.K the attached URL tells me why I can't use Imgur.com
Photo uploading facility

As stated I have an A3 1.9Tdi 8P1 March 2009 (right hand drive)
Can anybody tell me the exact location of ALL of the modules?
Once I know these I will then set about inspecting them all, when I say "inspecting" I operate that piece of equipment and see if I get any reading on my DVM.
I'm still unable to understand why I can't a reading "can't see module etc" when using my HEX-V2
