61 35... Notes on ESD protection (Electro Static Discharge)

WARNING: This page is about a different car, the 2013 BMW 550i GT, 2012 BMW 550i GT, 2011 BMW 550i GT, and 2010 BMW 550i GT. 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 themselves when they touch 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 and multi-pin connectors directly!

Touch electrical components by their housings only.

IMPORTANT: To avoid damaging or destroying electrical components as a result of electrostatic discharge, it is absolutely essential to observe 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)
Read and comply with user information on using the associated special tool 12 7 060

Personal protective equipment:

Electrically conducting clothing (high wool content, antistatic shoes required).

These can primarily be identified by the logo on the side.
