BMW S50B32 output mystery

Related to BMW S50B32 outputs

We received a device S50B32/v3/13410 ... repair (OID 17028) BMW S50B32 "output mystery" with "ign cyl5 problem".

To our surprise, we found that outputs were good (also tested with load), it was a bit puzzling for quite some time.

Since the HW actuates all outputs (not having changed anything), the only possibility we can speculate that the home-swapped cyl 5 ignch6 IGBT legs (bent incorrectly when repaired at home) contacted the clamping plate, causing problem... This could even damage an ignition coil if not sufficiently protected by fuse.


However, this does not explain IAC output issue, since IAC output atuates properly.


The outputs work as on BMW S50B32 outputs, mechanically repaired the cyl5 IGBT (to clear the clamping plate, to not cause short as with the home-swapped IGBT).

Sending the device back.
