61 35 ... Notes On ESD Protection (Electro Static Discharge)

WARNING: This page is about a different car, the 2007 BMW 550i and 2006 BMW 550i. However, it is still accessible from the selected car via links, so may be relevant.

Special tools required:

12 7 060

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 component in its original packaging (always pack the component away immediately)
