at the rear position on ATW? I tried 2 last year and got heater circuit DTCs immediately. Went to an OE and it was fine. Cracked my cat not to long ago and once I put a new one in the rear 02 had failed again. Tried 15738 again and it gives me the heater circuit error again. I read through some old posts and there is conflicting info. Plenty of AEB guys use this part # and it's fine. I'm pretty sure AEB and ATW have different OE part #'s for the rear, so I don't see why the bosch site says they use the same universal for the rear. Anybody get 15738 to work as a rear 02 replacement?

I had luck using the VW(front) $25 sensor in the rear before, so perhaps this Bosch universal front will work in the rear for ATW.

I am running the VW 25$ one in the rear without issues.

I guess what I'm getting at is that bosch says that the universal sensors for front and rear are different. THe VW one works both front and rear. So I think Bosch has the ATW universal rear part screwed up in their system. They have the same part # for ATW rear universal and AWB rear universal which makes it more believable that the ATW part # is wrong.

the same heater circuit code that the rear one throws immediately. And it's $20 cheaper. If this ends up working out I'll email Bosch about this to fix this problem.
