**Strangest Observation** Anyone else notice this?
During the NE snowstorm lately I decided to test out the car's electronics and quattro.
First test was ESP and ABS. They worked great, but when they were activated, the AM radio station I was listening to would revert to static until the electronic 'kick-in' was de-activated.
I thought if I turned off the ESP and let quattro work alone, if the car slips, there would be no electronic 'kick-in' therefore, no static on my AM station. But to my surprise, even with ESP off, and slip occurs, AM reverts to the static sound until there is no more slippage/quattro working.
I thought that quattro was mechanical and NOT electronic. According to my test, it seems like there is also an electronic component to quattro.
thoughts?

Even when you turn ESP off, you're really only lowering it's sensitivity...
It will still do it's thing if it senses danger. It will just take more slippage for it to engage.

True..I guess there is no way to ever get quattro to work alone it seems like with any type of
slippage, ABS, EBD, ESP, and quattro will go to work to prevent loss of control. kinda makes me loose a little admiration for quattro cars..since all these electronics save the day too insteadof plain quattro.

It's probably the ABS system...try this...
Find a slippery section of road, turn on your AM radio, run the car up to 45 mph, and nail the brakes to kick in ABS. Does the static return?
Quattro's center diff is mechanical, however the side to side power distribution is aided by the ABS system (EDL I think it's called). If the left front wheel is slipping, I believe ABS is applied to that wheel, and the front diff will transfer power to the right front wheel. I think that's what you're observing, not the ESP.
