so i get my car back after a week in the shop got new control arms and axles, and just started my pedal starts to pulsate and i can hear some type of noise coming from the engine bay. could the be my break booster. i have a 00 a4 1.8tm and it only happens when i'm just about to stop.

 

take off your wheels and check for loose connections. do you have any warning lights on?

 

i have lights, it's strange it only happens around 10 mph or less

 

sorry there are no lights on, it feels like the abs kicks in way to soon

 

It's probably just looking for attention. Whatever you do don't laugh, it'll only encourage that kind of behavior. Take it to another shop and get it checked out or bring it back to the same people.

 

^heh, it's ticklish! [sm=smiley36.gif]

It could be a speed sensor issue. If your axles were recently replaced, it's likely related. The tone ring for each of the VSS is on the axles.
