After reading many reviews on the internet about the advantages of cleaning the throttle body, I decided to have a go myself. Since TV was rubbish last night, the throttle body got some attention! .. On the Audi B6 2.0 Sport there was a lot of dismantling to be done before you could get good access to the bolts holding the throttle body in place. But once dismantled you could see clearly the carbon build up.
I used some Carb cleaning which I purchased in Halfords for Ł5.49
Halfords | Wynn's Fuel Injection & Carburettor Cleaner 500ml
I cleaned the Throttle body using a cotton bud and a microfiber cloth, as you can see it was quite dirty, however my previous car was worse! Once I had everything reassembled I used Vag Com to complete a re-alignment. The car drives much smoother now and is more responsive. If TV is rubbish one evening, give this a go!
Anyway below is some before and after pictures!
