Hey all, I purchased an OBD diag tool, and I tried it on both my 3 and 5 series. My wife's three series that doesn't idle had no problems. That is a subject for another thread. The five, which runs great, has three error codes.

1. Error code 19: Pre 02 Sensor heater problem
2. Error Code F5/F6: Secondary air system flow too low, cylinders 1-3, and 4-6.

Do I need a fluke to test number 1? Is there a test other than replacing parts that more seasoned BMW enthusiasts/mechanics know about? I'm humble in my limited auto repair skills, so if your explanations are tailored to a 10 year mechanic's apprentice, I appreciate that. For no. 2, other than checking the hoses, is there anything I can do before plunking in new parts? Testing the secondary air pump/valve? If hoses/parts are dirty, what options do I have for cleaners? How does one test these parts?

I'm new to this site and intermediate auto repair (beyond fluid changes and air filters). Any advice is appreciated...

Thank you,
Fro3and5series
