    Hi All! Long time lurker, first time posting. Just want to say how helpful these forums have been. My 2007 Z4 got the big R sticker at the garage this week because of these codes: 2C9E - Lambda Probe Heating in front of catalytic converter - input signal 2C9F - Lambda Probe Heating in front...

    Hi All, I need some community help on this one. I've done 98% of all the maintenance work on my X5 since we purchased it in 2009. First time that i've been stumped. Car was running fine, but had a check engine light due to "catalytic converter error". I thought I would try replacing the...
