- Leave the electrical components in their original packaging until they are being installed. Only use the original packaging for returning the product. 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 (ELECTROSTATIC DISCHARGE) PROTECTION .
NOTE:
RISK OF DAMAGE
Damage to the electrical controller drive and the mechanical connection.
Improper handling of the electrical controller drive can lead to malfunctions or failure of the electrical controller drive.

- Do not release the screw connection between the wastegate linkage and the control rod on the wastegate valve controller and do not twist it.
- Avoid exposure of lateral forces to the control rod of the electrical controller drive.
- Remove all the screws on the electrical controller drive before the control rod on the wastegate linkage is detached.
- Have the special tool 2 469 240
ready.
- Unlock plug connection (1)
and disconnect.
- Unlock and detach the retaining clip (1)
.
- Release the screws (1)
on the electrical wastegate valve controller (2)
with the special tool 2 469 240
.
- Carefully
detach the control rack (1)
of the electric wastegate valve actuator (3)
from the pin on the lever of the wastegate valve (2)
.
In the process, any effect of lateral force on the control rod (1) is to be avoided.
- Feed out the electrical wastegate valve controller (3) from the cylinder bore of the compressor housing (4) in the arrow direction and remove it.
