Need help on a BMW engine faults?

Hi I have a 1997 BMW 328 covertible I was checking my engine fault and came across two faults. 1 was "secondary air system fow too low Cyl #4-6". 2nd was EVAP large leak detected.For the guys and gals that work on their car would a o2 sensor cause these faults? and is it easy to fix the two faults meantoned by a novice?

Thanks

I doubt that there is already a secondary air pump (system) in your car. So your fault for the secondary air to me is "suspect". Tell us what scanner you used and the actual fault codes you got. Better still, tell us the last 7 of your car's VIN. I never recommend replacing anything without a proper diagnosis. If your 02 sensor is bad, you would get a fault for the 02 sensor itself so replace it at your own risk.

Evap large leak can mean so many things. Leaks in any of the following can cause such a fault--- tank cap, filler tube, hoses, charcoal canister, expansion tank, fuel tank, vent valve, pipes and hoses of the evap system all the way to the intake manifold. Most of the time, the fault is due to the gas cap not properly secured/tightened. Just re-set your gas cap and clear the fault. The evap system has no relation whatsoever with the 02 sensors.

ADDITIONAL COMMENTS....

You did not mention specifically what particular Bavarian Autosport code reader you used. But anyways, it is obviously not an OBD2 code reader, for the fault codes you mention are not OBD codes. I would suggest that you have your car scanned at Autozone or Pepboys with a regular scanner.

Then repost the findings.
