My rear downsteam O2 sensor has packed up, causing the engine light and speed control lights to flash and giving P0037 code. I've been told by Chett that it's not essential and I can either replace at vast cost, or delete the O2 sensor group of codes. Can anyone please advise how this is done? He (Chett) offered to assist if I brought the car to him, but my car is in Kimberley and I'm in Qatar...

This is unfortunately not something you can DIY if you don't have a Tactrix cable. You need to be able to access the ECU and write to it. Chett would physically disable those error codes in the ROM.

The car is at a mechanical workshop with a professional scanner, which is able to access the ECU, that's why I know the code, but they are not sure how to delete the O2 group of codes to disable the error...

Yep, they wouldn't be able to do it. You need to be able to reflash the ECU/ROM. This is something a tuner is capable of and usually not a workshop who can generally only read and clear error codes.

Ok, so RockAuto it is... Pity about the long wait! Local stealers want to rip me R2,770.00!

At least I don't have to pay RA in ZAR...

Thanks for the offer guys, but I managed to get a new one from RockAuto for the equivalent of R700.00 plus postage. All in, still half what Subaru dealers want to charge...it's pathetic what we have to pay for parts here!
