1. Automatic transmission pressure regulating valve 8 (N510), depending on the date of manufacture, also solenoid valve 1 (N88)

2. Automatic transmission pressure regulating valve 7 (N443)

3. Automatic transmission pressure regulating valve 6 (N371)

4. Transmission output speed sensor (G195)

5. Automatic transmission pressure regulating valve 3 (N217)

6. Automatic transmission pressure regulating valve 5 (N233)

7. Automatic transmission pressure regulating valve 2 (N216)

8. Automatic transmission pressure regulating valve 4 (N218)

9. Automatic transmission pressure regulating valve 1 (N215)

Mechatronic, Transmission Control Module (J217), Sensor and Pressure Regulating Valves - Part 2





1. Transmission input speed sensor (G182)

2. Transmission control module (J217)

3. Transmission fluid temperature sensor (G93)



• The multifunction transmission range switch (F125) is located on the Mechatronic as well.

• OBD checks all the components named.

• Only the complete Mechatronic unit can be replaced.

Transmission Range Display (Y6)

• Installed location: The transmission range display is integrated in the instrument cluster.





• Replace the instrument cluster if one of the transmission range displays is faulty.

Selector Lever Sensor System Control Module (J587) and Tiptronic Switch (F189)





• Installed location: The selector lever sensor system control module and the tiptronic switch are a single unit - 2 -, which is clipped to the selector mechanism function unit - arrows -.

• Ignore - arrow A -.

Refer to => [ Selector Lever Sensor System Control Module with Tiptronic Switch ] Selector Lever Sensor System Control Module with Tiptronic Switch.

Shift Lock Solenoid (N110)





• Installed location: The shift lock solenoid - 1 - is clipped to the selector mechanism.

Refer to => [ Shift Lock Solenoid (N110) ] Shift Lock Solenoid (N110).

Transmission Park Selector Switch (F305)





• Installed location: The transmission park selector switch, which consists of two reed contacts - 1 - and - 2 -, is installed on the circuit board - B - on the shift lock solenoid - A -.

• The transmission park selector switch can only be replaced together with the shift lock solenoid.
