1. Knocking noise coming from from passenger side footwell. Happens for example when your cruising in 3rd and then drop a cog, sounds like something is loose. Also occurs when your moving off from rest. Been told it might be anti-roll bar droplinks. 2. Changed rear pads the other day, bled the brakes in correct order, but brake pedal is still soft as *****. Cars going in on Friday to Audi dealership to check an outstanding recall (brake vacuum) will they bled/check the brakes, so is there any point in me doing it again? Any ideas? Thanks in advance.
