WARNING: This page does not describe the selected car, but rather 16 other vehicles, including the 2006 BMW 325Ci, 2005 BMW 325xi, 2005 BMW 325i, 2005 BMW 325Ci, and 2004 BMW 325xi. However, it is still accessible from the selected car via links, so may be relevant.

Special Tools Required:

NOTE: For special tools, refer to GENERAL ELECTRICAL SYSTEM - SPECIAL TOOLS - 3 SERIES (E46)

NOTE: Electrical components which are particularly sensitive to electrostatic discharge (electronic control units, sensors, etc.) are marked with the ESD warning symbol.

E - Electro

S - Static

D - Discharge

Statically charged persons can discharge by touching electrical components.

NOTE: Humans can only detect a discharge starting from a level of approx. 3000 V.

The danger threshold for electrical components already starts from a level of approx. 100 V.

IMPORTANT: Do not touch pins or multi-pin connectors directly!

Touch electrical components by their housings only.

IMPORTANT: To prevent electrical components from being damaged or destroyed by electrostatic discharge, it is absolutely essential to comply with the following instructions:

When replacing electrical components, leave the replacement components in their original packaging until immediately before they are to be installed.
If necessary, always return a removed components in its original packaging (always pack the component away immediately).
Read and comply with user information on using the associated ESD special tool 12 7 060
