So, next question: what interaction does the cluster have with the ABS that requires changing to the C5 one? I thought it only talked to the ECU/TCU, other than warning lights?
Your English is fine, no worries  I appreciate you indulging my curiosity. |
So high pressure from MC going to this external pump which have one non return valve-which make internal bleeding and return fluid directly to tank. This idea is laying to me for more than 10 years, im not having D2 anymore.
About warning lights- is not solution to have christmass tree on dash. At this scenario not have ABS-ESP and etc. This can be done with bypass external pump. But for me is not solution.
So to work everything perfectly is need to be changed ECU from A6/S6 4.2, TCU/if have AT/, and of course instrument cluster to work correctly ABS. To be detailed cluster is needed only for correct reading of speed for ABS.
