Software update for throttle flap did not. throttle flap defective??

Hello, after laaaangem engine ruckeln and nem replaced LMM, solenoid valve for Tutbodruck (TCV) and cleaning the throttle flap and a new engine software update, should be played today at Volvo a DK update. However, the playback did not work, as the DK did not take any more. According to Volvo the engine ruckeln and the restless engine run at 2000-3500 U/M from just this now broken DK. They said that the DK was 99% defective. In the error memory however, nothing is stored….! buy the Volvo from the free small dealer and have now agreed so ( despite warranty) that I participate with 350 Euros. Can one get for the V 70 II 2.4 Turbo EZ: 11/00, also a different DK than the Magnetti Morelli?? E.g.: ne Bosch? First of all have the information that the Bosch would fit from 08/2001 ??!!! Is that so? Does the DK really cost 700 Euros without installation?
