The diversity reception unit needs power and has some connections related to the OEM radio. Since you have replaced the OEM radio, these connection may have been altered. Common complaint when the OEM radio is removed....

There's a ton of wiring variations; you can see them all on the newTIS.info web site...

I'll have to check that out, thanks.

Today was almost successful. Replaced the front upstream O2 sensor, oil drain plug, and rear pads. Car runs much smoother with the new O2 sensor, but i'm still getting codes for all 6 misfires. I never feel any hesitation though so I'm not sure why the codes are getting thrown.

But in recovering the fresh oil while changing the drain plug, it gave me an excuse to use this guy. I 3D printed it last year when I picked up my Z3.
