hi trying to find out why my a3 wont start i brought an cable off ebay got vcds lite the ports check ok
test says port ok interface found.
i can get readings from the abs controller,the central locking & radio
but nothing else if i try any others i get no response from controller any ideas plz
just to say that when i switch my ignition on i only get the battery light to come on but replaced the battery and still the same
