Rear windscreen wiper engine over

moin leuten! nu is for the first time a non-wearing part on my sunnylein over… and that, as mentioned, the windscreen wiper motor… my question now: with which is the identical? at ebay I find only some for the micra k10. maybe someone also has a share number!? maybe someone has an idea what it costs at the dealer or whether it still exists at all? mfg JoelAK
