Hi everyone....I've just changed the Battery on my A4 Avant and am now getting rough idle up and down from 400rpm to 1000rpm and the whole thing cutting out if I brake even normally......any Ideas Im desperate!
could be a few things... terminals are very sensitive so make sure u got off all the corrosion off them and on the new batter take a metal brush to scratch them up a little bit (the positive and negative)... if that dont work, go for a tune up that should work what yr of car is it?
It's a 1997...thing is it start fine runs fine but when you brake it cuts out...v dangerous... Just fitted a new battery,so was wondering if its a ecu problem...needs resetting? Trouble is my Audi dealers a money grabbing place so need a no Audi dealer fix!!
