Model: MINI Cooper S electric. Posted 4 September, 2022. The DQ200 DSG is sealed for life, and there are 2 oils. in the box and in the MCU. No servicing recommendations, guidelines or schedules and no need to change the oil. But some do anyway, because they are sealed, but not for life. 1. The first time I got 2 of them - "Reduced Oil Pressure Switch Malfunction" with the same code (P164D00) and "Oil Pressure Switch 3 implausible signal during engine operation" (P164C00). It preceded a warranty replacement engine & turbo (the switch was not the cause). The other 2 times it was shortly after the new engine. fSD2.
