[QUOTE="Herbert, post: 441094, member: 18029"] Typical lifespan I won't know as mine still working after 214k km but had degraded coz fuel consumption was rather high. I have seen some pre-cat O2 sensors going bad at 80k km as read out by GT1 computer. Bosch's web site suggest replacement of O2 sensors at 100k km. O2 sensor is more important that the post-cat for fuel consumption. Bavarian Auto prices for pre-cat O2 sensor are (1) Original Bosch with BMW logo RM 1,200 per pc. (2) OEM Bosch RM 480.00 per pc.
