A couple of queries that I hope those here may be able to help.
The first one is.
My 525D is having a 'shaking' moment whilst at idle. Not a huge thing but just something that you can feel the engine doing when stopped at traffic lights etc.
Got INPA running so took a screen shot of the area of concern
This is with the engine idling at about 750RPM. Injector 2 is slightly higher than the others.
When I give the engine a few more revs (1500rpm) the shaking disappears. Car accelerates fine pulling all the way to nearly 4k rpm.
The 'balance' part of INPA (F6) shows they are quite close.
The second one is with regards the AirCon part.
Checking the error log there is a part that is faulty but not sure what it actually is or means.
What is the AUC Sensor as its reported Open Circuit.
