Faulty servo going down hill ???
On my sons A4 1.9TDi 2002 when going down inclines the servo seems to become intermitant with the pedal sudenly becoming very hard and not working ... he also reports the pedal going all the way to the floor though i was unable to get it to do this ... i've checked the fluid level which seems fine .... i'm wondering if there's a vacume hose that could have split thats getting pulled open when the engine learches forward..... anyone had a similar experience or know what it might be ??? it's obviously a dangerous situation to be in
