What benefit would an extension cable give me?
Has anyone got anymore ideas to why this thing won't connect? It's very concerning and my next step is taking it to someone to figure out why this won't work and the last thing I want is to spend hours on some clown troubleshooting something he has no idea about

Thanks mate. So just to confirm should I have 12v on that Kline pin? I currently have 2.4v

I guess I need to check those other two fuses as well

I have a factory VW radio, should I still just cut the wire out of it?

With android bluetooth works fine, but if you have iAnything make sure the device says it is bluetooth compatible with iOperatingSystems. If not you will need to go for wireless and create an adhoc wireless network. This has the disadvantage of preventing your devices accessing the internet if they are in range of the ELM327.

HTH

Yeh mate i had the same issue with the first one i bought it was very thick

But i checked pin 16 again fellas and turns out there is in fact power there

So anymore ideas that could be stopping this from working?

Have you tried a different OBD scanner on it?

**Stocky789** · 30-05-2017, 05:14 PM

I have just bought myself a VAGCOM cable im hoping this will work
Do you reckon it was a waste of money? Or will it work?
Whats the difference using a VAGCOM opposed to another scanner?

Which "VAGCOM cable" did you buy and from where did you buy it?

I would say try the adapter on another car to make sure you didn't get a faulty one, but now you've said your second one doesn't work either.
Either the adapter isn't making correct contact with all the pins, as mentioned here previously, or your OBD port is somehow damaged.

Anything after 1996 should work with generic OBD adapters, if not, you probably have to get one that supports the K-Line protocol.
Check that PIN7 does NOT have 12V on it.
If does, your scan tool will try to pull it to ground to initiate a comms session and blow the fuse on the K-Line, at this point I don't think it will work anymore.

However I have accidentally done this before and didn't blow any fuse and managed to get comms later with K-Line supported adapter (USB only).

The adapter I bought was advertised as a KKL VAG-COM 409.1 USB Auto Cable.

Alright so where is the fuse for the Kline module?
I'll check pin 7 for power tomorrow and see if there is any
I bought my vagcom cable off ebay i assumed they were all the same?

Ive tried both the adapters on several cars and they all worked except for my golf obviously
