Hey guys new to the forum and new to audis.... I picked up a 1999 audi a6 Quattro with 137,000 miles on it for peanuts.... Thing drives good only two problems, one; there is a slight ticking while idleing and disappears when the rpms go up, was wondering if i could throw some lucas additive to quiet it down a little and two; the directional switch is broken, it works but you hit a bump and the left hand directional turns on, it doesn't kick back when you turn the wheel, i got a new one but my question is does anyone have a write up or pics to show me how to replace it, i have a feeling i have to remove the airbag, which i always hate to do.... So any help will be greatly appreciated thanks guys
