Removal and installation of the combined valve (regulator)
The given procedure should not be made in house conditions. Removal and installation of a regulator do not cause difficulties, however correct prorolling of the hydraulic block of management (HCU) is enough challenge. In view of affinity of an arrangement of the valve and HCU ABS air easily gets in HCU at easing штуцерных connections of hydraulic lines.
Prorolling HCU should be made with application of diagnostic scanner DRB II (then the system should be pumped over manually). The scanner is rather expensive device and can serve as a favourable investment only for a workshop of dealer branch. If on your car there are any problems connected with refusals of the combined regulator, tow off it in a workshop of dealer branch or on a specialised car repair shop.
