VCDS is free to use. You can download the software onto your PC and use it. However, if you want support from Ross Tech and updates, and a guarantee that it will do the job, and with a built in dongle that protects your computer you need to buy a genuine lead from Ross Tech or one of their authorised distributors which includes a licence to use the software. Cheap eBay leads may give access to some functions but they're not guaranteed to work properly and Ross Tech will not support you. Bite the bullet and pay the money. There is nothing better out there for VW/Audi/Seat/Skoda.

The description reads it's an EOBD tool. That will give you access to engine emission related data only.

I'd be somewhat worried that it say's make sure you are not connected to the internet "TURN OFF your internet connection!" - me thinks that looks like pirated software and it tries to phone home

Pirated software? I find that hard to believe because Amazon are not allowed to do that? Right?? Unless they are unaware of their product is pirated. Oh well, atleast it worked and I had my Internet connection switched on too but I think you are right as the software instructions were dodgy

As for the fault codes what is the solution then? Replace the entire battery? Glow plugs? Or what? In cold weather it has trouble starting the car, mechanic told me it is because of the glow plugs. That is one issue the other issue is the brakes are slow to respond, there is like a small delay when I press the brakes. And the third issue is the car shuts off sometimes randomly while its driving but turns back on fine (it doesn't always happen but it has happened to me during driving or when starting the car). Solutions ??
