Hi,
Wondering if anyone knows what these codes are referring to? Googled but they don't seem to be standard "P" codes, they are listed as messages from the climate control unit (IHKA3):
E71404 Message (OPERATION_KLIMA_SH, 0x2A2, FA): OP_IVNT invalid signal
E71405 Message (OPERATION_KLIMA_SH, 0x2A2, FA): OP_PFN_AMOD invalid signal
I've noticed in Bimmercode this ECU always has "Critical errors in memory" but read that was a normal thing. I've cleared these and they keep coming back.
Thanks!
