abs warning lights on

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?  

 

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.

Does anyone know if I need to program a second hand abs pump and control module if I swapped one in ?

Yes I believe you do. 

Is there a particular part likely to be the cause?? The pump, the aluminium bit the plug in module?
