This did not work for me unfortunately. Just tried it. Still getting p0058/2C9F for post cat bank 2 o2 sensor heating circuit. I verified 12v on the heater circuit at the o2 harness plug so I'm guessing it's just a bad o2 sensor and not a problem on the body side or the 30A fuse by the IVM (that should trigger both post cat heater errors).

Both post cats are new Bosch units of the splice in variety. Bank 1 has been fine since install, and bank 2 has been giving me issues since install. I've re-spliced bank 2 once already to verify it was not a continuity/resistance issue with the splices. Guess I'm going to just suck it up and order an application specific version this time. :rolleyes:

What did you do to / for your E53 today??
 

Can you read live data? % duty of heaters? You are having a different error than I had

I'll try and see what I can come up with. Ordered a new sensor just in case. It's from fcp so if it turns out to be unnecessary the return will be painless. I'll report back after hooking up the scanner.

Well, bought a parts truck and since it was not throwing any O2 codes I went ahead and swapped the O2 from it into my truck and so far so good. No more code. I ohm'd the parts truck O2 and the one I pulled out and was getting wildly different results between the two on the white signal wires. I'm guessing it was just a bad O2 out of the box... it happens.

New key order.

No that's in Saudi Riyal so ÷ by 3.75 = (USD)

Problem is that I have to order it from Germany and estimated time for delivery is 14 days.

Got my transfer case fluid changed out yesterday and reset the error codes via Foxwell. Not sure if this also resets "adaptations," but at least my fluid wear code is cleared. haven't driven it yet so not sure if it will ride any different. Old fluid was definitely past it's "use by" date. Took almost the fill liter of fluid.

Oh, and here's what you do when you realize you don't have a transfer pump after draining the old fluid... Short hose gets hooked to compressor to pressurize bottle. Long hose goes down into the fluid at the bottom of the bottle and the top part goes into the fill port of the transfer case. Kind of fiddly to modulate the air coming from the compressor... but it works. :D

Oh yeah, also changed my rear wiper to the e70 wiper arm version. Looks much cleaner back there. The plastic looks a little too grey though so I may hit it with some SEM trim black paint.

Listed it for sale.. 02 4.4 with guides and vanos done.

Fixed “check rear/brake lights” with aluminum paper to replace metal contact on light assembly.
