Hello all, my Persona's Oxygen sensor is giving problems. Proton has asked me to replace it, but they don't have stock at the moment, even at HQ/Proton Parts Center. Any other way to fix the issue?

Is the OEM quality / Bosch replacement a suitable replacement?
Proton mentions it's common for the O2 sensor to give way, especially after 100,000km. Current car mileage just passed 110,000km, running on NGV & petrol.

SC quoted MYR250++, but they don't have stock of the part.

Anybody experienced their ABS sensor no longer working?
Proton is charging me RM516.87 per sensor for the rear discs.
