Vehicles with VW/Audi 0B5 and DL501 transmissions often develop harsh engagements and harsh downshifts, and may overheat. This can be caused by bore wear at the clutch cooling control valve, which distributes cooled oil to the dual clutch assembly. Wear in this bore prevents critical cooling oil from reaching the clutch assembly. Reconditioning the bore and installing Sonnax oversized clutch cooling control valve kit 225740-01K eliminates wear to restore desired shifting and temperature control.
