My friend bought an 03 jetta. 4k miles onto the car and he blew apart the difurential which kill the tranny clutch and fly wheel. i think it was the differential. but anyways..this was all because he beat the bag out of the car and spun the tires everywere!!! so yes u can break stuff.
i read some where that VW have an open diff but what they do to help with wheel spin is apply abs to the spinning wheel but so that power will transfer to the one that has grip. this is done very fast but when the brakes go on and off they go 100% then 0% really fast and each time they do that it sends a SHOCK through the whole drive train, mostly CV joints, halfshafts, diff the trans doesnt really feel it. do that enough and your car is toast. best thing to do is to slightly let off the gas if your wheels are spinning.
