That was a pretty scary feeling... was going down Rt3 in mass, it's kinda drizzling... cruising along at around 65mph... and of course, with it bein route 3, traffic just suddenly and randomly slows down to 10 mph... so I hit the brakes, and it feels like nothing's happening... I thought I was hydroplaning or something... but then after a second or two, the brakes finally kicked in... man, that was quite a rush! ;) On a good note, at least I'm wide awake for work now!

I kind of get the impression that those who don't have the problem think the rest of us are either making this up or don't know how to drive. :0

I think it is only time until the "right" circumstances arise... I do not think some a4s have it others do not.

What the hell is AoA doing about this?

It only happens once a drive, though. The brakes heat up and the water evaporates thereafter. Just keep it in mind when you start out on a rain-slicked drive.

According to the recall:
"Audi has found that at ambient temperatures of below -4 [degrees] F under certain driving conditions a control valve in the brake booster vacuum system may not fully open. Should this happen, it could result in insufficient vacuum being provided to the brake power assist unit. Although the problem does not occur at temperatures above -4 [degrees] F, we recommend that the recall work be performed also on vehicles which are not regularly operated in the colder regions of the country."

And I can't stand it. Has anyone found a solution? Dealer says it's because of cold - which is complete BS because it only happens in the rain (not winter) and during summer.
