Chaps

When I'm in my manual GTi, and lets say it's on a damp road, uphill,a nd you pull away with some small amounts of enthusiasm, I can feel the traction control cutting in, but sometimes, its followed by a loud bang, or thunk from under the car. Almost as if the traction control is switching off, and the diff just reacted.

Not experienced this on other cars, and my description may not be great, but is this normal for your cars, and should I just be reacting to the ASR by backing off the gas?

Just keen to understand other experiences. Thanks
