O2 sensors

[jobimmer]

I've just changed my O2 sensor the one on the exhaust pipe right under the bottom of the passanger seat but some one told me that i have 2 O2 sensors, i tried to find it but can't seem to see it any where. Can anyone tell me if they have two or 1 i have a 95' TI.

95 = OBD I = one O2 sensor
96+ = OBD II = two O2 sensors

not sure if part numbers for pre-cat O2 sensors are different or not ... so let me check the ETK (hint: search for lambda)!

95 (used 12/94 build date): 11781247235
96, pre-cat: 11781247406

from bimmerparts.com:
95: bosch c5010-33518 (~$71)
96, pre-cat: bosch c5010-61266 (~$100)
