Hi Ali. Thanks for contacting us today. Cleaning the throttle body while it’s on the vehicle is possible and shouldn’t hurt anything. However, it’s not very effective. Most of the time, the carbon debris that is trapped is in hard to access areas. While some mechanics use seafoam and other degreasers like this, they can produce problems with sensors. I think your best opportunity for success is to follow instructions provided by Volkswagen in their service and repair manual.
