bought one off ebay but where does it go? my fitting instructions are in German!!! Can anyone send me instructions or pictures to help fit? Thanks

I think you need to lift off the top cover and on the front LH side you'll see the plug, it fits in between that connection.

There is a pictuere here http://www.briskoda.net/forums/t20925-tuning-boxes.html

Yep take off the engine cover and look leftish of the air box and there's a plug which looks like the one on the tuning box - this is the fuel temp sensor. Simply unplug the fuel temp sensor's and plug in the tuning box and then connect the fuel temp sensor's plug into the other side of the tuning box.
