Moin, at the omi of my Schwegering (X20XEV Bj.99) the servo pump has said goodbye. Found used on the scrap yard (in the short term there was no new one here and the car was used mainly) and changed (was not me, therefore no part number – but was used by another X20XEV). Now I wanted to order a new one to replace the used one at the next service – was installed a 90473168 – if I entered the at Daparto only V6 models under “pass” When you enter the vehicle data at Daparto, pumps with the numbers 948049, 90409232, 90543246, 948077…..but not the upper ones. OK, now someone can say that in the 21 years maybe the car was made….but….Vehicle was bought by the first owner with 14,000km and is in their possession since. Very unpredictably, that the vehicle with such a mileage and after 4-5 years the servo pump was replaced. Out of pure curiosity I would h be happy about a logical explanation What is more important to me is which pump should I buy new. Part of the question, since at 90473168 only one pump is offered and the price is 2x higher than the one provided by search engine, from which there are also large selection of manufacturers. Thanks in advance
