So i got a friend with a reader to check why my EML and anti polution keep comming on every few days. This was the code that came back.
P0414
For MM6LP; Check the auxiliary air pump for siezure, usually caused by water ingress. Also check the fuse supplying it. (BM34).
Anybody had any experience with this or got any tips?
Thanks

After a bit of research i found this.
Generic OBD Error Code Details for P0414
Secondary Air Injection System Switching Valve "A" Circuit Shorted
What does this mean?
OBD Code P0414refers to
The optical sensor provides a high resolution signal to the Powertrain Control Module (PCM) by counting pulses on the sensor disk located in the injection pump. The high resolution is one of the most important inputs by the PCM for fuel control and timing. This test monitors the number of high resolution pulses which have been missed (not detected). It's based on a comparison between the number of pulses that were detected since the last pump cam pulse and the number of the pulses that should have occurred. There are approximately 64 high resolution pulses for every cam pulse.
Symptoms
Possible sumptoms of OBD code P0414
- Engine Light ON (or Service Engine Soon Warning Light)
Causes
Possible causes of OBD code P0414
- Open or short in the optical sensor circuit - Optical sensor connector - Damaged optical sensor - Damaged PCM or ECM The Error code is generally activated on detection of the following conditions: Some high resolution pulses are missing from the optical sensor to the PCM
Possible Solutions
- If damage, repair optical sensor circuit - Replaced optical sensor - Replaced PCM or ECM
