Sadly neither one of our interfaces will work with your golf. Its a PD motor requiring a CAN connection. I should've spent the extra and got it but... I didn't.
The Micro-Can is the cheapest option for you.
I do believe its worth it, if you're going to be modding or doing your own work. If you just want to scan and clear codes there are cheaper alternatives.
Pretty neat tool though.
If you just wanted to see it work, I could show you with my car some time. I'm in S'toon during the week.
