NOTES ON ESD PROTECTION (ELECTRO STATIC DISCHARGE)

Special tools required:

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

IMPORTANT: Read and comply without fail with the notes on this subject from Service Information 2 06 04 128.

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.
