Notes on ESD protection (Electro Static Discharge) (M3 base, M3 Competition, M3 Competition M xDrive, M3 CS)

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

  Attention! 

  Statically charged persons can discharge themselves when they tap electrical components

  NOTE: Humans can only detect a discharge starting from a level of approx. 3000V
  The danger threshold for electrical components already starts from a level of approx. 100V

Attention! 

Do not tap pins and multi-pin connectors directly! 

Only tap the housings of electrical components

Attention! 

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
