Hey Guys, I am an occasional lurker. I am extremely thankful for the whole door handle carrier replacement info. Gotta tear into that this weekend.

Here recently the Service Engine Soon light came on. I checked the codes and got the following codes:

After Cat O2 Sensor Heater Circuit Cyl# 4-6
After Cat Fuel trim system Cyl# 4-6
O2 Sensor adaptation limit Cyl# 1-3
O2 Sensor adaptation limit Cyl# 4-6
Misfire Cyl# 6

I am certainly not a certified mechanic but to me this sounds like there are atleast 2 or 3 O2 sensors that need to be replaced.

My wife who is the primary driver (lucky dog) says if she didnt see the light on she wouldnt thing there was a thing wrong with it.

Ohh and our X5 has got a touch over 155K on the clock.

Thanks ahead of time!!!!!
