The vacuum pump of my 2009 MCS is leaking oil. I purchased a vacuum pump O-ring to reseal the pump I have not replaced the O-ring yet. Yesterday, a got a misfire and 4 error codes: P0503 Speed Sensor, P1497 Downstream Throttle Air Leak, P0303 Misfire Cylinder 3 and P0300 Combustion Misfires Several Cylinders. It is possible that the code P0503 Speed Sensor and P1497 Downstream Throttle Air Leak could be caused by the vacuum pump? The car has other issues.

No, not likely. Most likely other issues causing those faults.

Seems you have multiple issues going on. When is the last time you replaced routine maintenance items on your MINI? Such as filters, spark plugs, etc?
Here is some info on P1497: http://forums.pelicanparts.com/bmw-mini/940120-vent-tube.html For P0503, check and see which wheel speed sensor is your issue. You can specifically find out which one is an issue with the proper scan tool. |
