From vehicle identification number (FIN) 627648, plug for electric machine temperature sensor (B94/2) was changed.
Old version of plug is 12-pin. New version of plug is 4-pin. When replacing electric drive, it must be checked which version is installed.
Only electric drives with 4-pin plug housing for the electric machine temperature sensor (B94/2) are delivered as a replacement part.
If a 12-pin coupling housing is still installed at the engine wiring harness, this must be replaced by a 4-pin coupling housing.
4-pin coupling housing A 000 545 70 17 and contact sockets A 002 982 58 26 must be ordered in addition to the new electric drive.
