FYI for DIY and maintenance +

There are a lot of procedures in the above links.

The MAF Sensor is easy but very fragile.
The other sensors (If it ain't broke don't fix it.)
If you read the Mike Miller schedule he doesn't really say much about cleaning sensors.
And he is the maintenance authority.
The Vanos solenoids are sometimes cleaned to clear up vanos problems.

google Mike Miller BMW
