minimum would be pump, abs ecu and harness mate, plus 4 x wheel speed sensors and 4 x hubs with the detector rings.
To the OP - if you can get a hold of the codes from the inside front cover on the service book it has the options the car came with, such as abs, leather etc. Need to run it thru the options vin decoder and it will produce a list, cant remember the site but you just google vag vin decoder
you need all the codes - not just the vin btw for the full options list.
