11 65 020 Removing and installing/replacing exhaust turbocharger: Notes

Hot surfaces. 

Risk of burning! 

• Perform all work only on components that have cooled down.

Electrostatic discharge. 

Damage to or destruction of electrical components. 

• Leave electrical components in original packaging until just before they are installed. Use the original packaging only for any return shipments. Always package removed components straight away.
• Read and comply with user information on using the associated special tool 12 7 060.
• Only tap the housings of electrical components. Do not tap pins or multi-pin connectors directly.
• Wear electrically conductive clothing and antistatic shoes (with ESD symbol).
• For additional information see: NOTES ON ESD PROTECTION (ELECTROSTATIC DISCHARGE)

For exhaust turbocharger damage:  Check the pressure pipes, charge air cooler and intake plenum for foreign matter, damage and correct functionality.

If the oil return line is exchanged, then the connecting pipe to the oil sump must ALWAYS be cleaned, as the connecting pipe can coke.

Prior to replacing the exhaust turbocharger: Observe the notes on troubleshooting on the exhaust turbocharger.
