I've never had a problem with the universal sensor (Bosch or other) for
the L-jetronic applications. The two heater wires are not polarized and don't
connect to the ECU. According to the 164 wiring diagram, the heater wires
don't go to the ECU on Motronic either. Perhaps there was a short inside the
sensor??

That said, I have no problems with the advice of going with OEM if you can.
I just did for the 164LS O2 sensor. The price wasn't bad ($155).
