Component Abbreviations and the usage at BMW

[shogun]

Do you know what DZM, ACC or EDC means? What does the car maker say if they want to use a AHPS?

The secret is that many OEMs use different abbreviations and shortcuts do describe the components used in their cars.
Most time also within the component these shortcuts can be trademarked or are copy-protected.

The effect is that with increased amounth of components and different branded names for actually similar components at the vehicle maker, as well additional even the local company internal rules for used language standards increase and multiply the possible abbreviatens used siginificantly.

This sometimes it is getting very confusing when suppliers and OEMs talk about their used components.
And it is discussed in many different news-groups.


Abbreviations@BMW

One of the most popular OEM with very complicated and in the first sense unclear abbreviations is BMW.

The problem is that they are using German as the base language to create their abbreviation.

This makes the Tire Pressure Control to “RDC-Reifen Druck Control” or the climate control panel to “KBT Klimabedienteil”.
