Garage told me you have to make sure your not on the Internet whlist on vag.com otherwise they can find out your using it without a licence and get done for it. . . Is this true?

The cable we are talking about is the official licensed version - costs around £270 from offical UK distributers.

I got mine from Marshalls Industrial

Cheap ones on e-bay may be illegal copies

Shouldn't matter if you have a licensed and paid for version - would you honestly plug an out of date pirated diagnostic computer into your 9k+ motor??

I have one too. 

They may seem expensive to buy but
d) When you decide to sell it you will get most of your money back.

As per Andy has written, you will definitely get your money back when or if you decide to sell. Used ones on ebay are selling around the £250 mark.
Hence i shall also be buying one from Gendon fairly soon

Yup, no point buying a dodgy one IMO. If you're planning on keeping the car for a while, just fork out the money and sell the cable when you sell the car.
