The Audi RS4 MK2 electric steering rack, can suffer from electrical failures and mechanical failures and also from excessive noise , this can sometimes be caused by water ingress into the steering rack, electrical failure can be due to internal electronic components breaking down. When we rebuild both the electrical part and the mechanical part of the rack, we also program the rack with the latest audi software version for your car , this will ensure that the rack will fit and work without the need for further coding/programming.
