A3car19tdi Posted September 28, 2021 Posted September 28, 2021 Hi all. I have this A3 2010 1.9tdi A red brake warning light has come up and the yellow traction and abs light on. My local garage plugged in and he was saying it's the abs pump/ module etc but he wasn't sure and couldn't narrow it down. Will the car give me any codes some how ,any secret menus? I had the same on my BMW once and had to replace the aluminium part on the abs pump which looks similar. I have a couple of OBD2 dongles but they are a bit unclear with what they show. Anyone point me in the right direction?
cliffcoggin Posted September 28, 2021 Posted September 28, 2021 As far as I recall those can also be the symptoms of an instrument cluster fault or an ECU fault. I don't know how you would pin down the actual problem except by replacement, which of course is a hugely expensive solution that could easily exceed the value of the car.
A3car19tdi Posted September 29, 2021 Author Posted September 29, 2021 Does anyone know if I need to program a second hand abs pump and control module if I swapped one in ?

Steve Q Posted October 5, 2021 Posted October 5, 2021 More likely the pump. But don't rule out the other problems as it could be instrument cluster or ECU etc.
