Throttle body

Warning

Be careful if the car is warm. The coolant is hot and there is a risk of burns from the intake manifold.


To remove


1. Turn the ignition switch to OFF.

2. Remove the engine cover.


3. Unscrew the expansion tank filler cap to release the pressure, if any, and then screw it back into place.

4. Pinch off the 2 coolant hoses going to the throttle body.


5. Detach the charge air bypass valve hose and the two preheating hoses.


6. Detach the lower vacuum hose.

7. Slightly slacken the turbocharger delivery pipe's retaining bolt in the cylinder head.


8. Undo the hose clips and bend up the turbocharger delivery pipe. Remove the rubber bend from the throttle body and turbocharger delivery pipe.

9. Disconnect the throttle cable from the throttle body's pedal arm.


10. Unplug the limp-home solenoid's connector.

11. Unplug the throttle body's 10-pin connector.

12. Undo the 3 throttle body retaining screws.

13. Lift up the throttle body and detach the hose under the limp-home solenoid.



To fit

Fit in reverse order.

Spray all connectors with Kontakt 61 contact cleaner (part no. 30 21 763).

Change the rubber seal between throttle body and intake manifold as necessary and coat it sparingly with vaseline.

Tightening torque: 10 Nm (7.4 lbf ft)

Important

The limp-home solenoid will be activated when the ignition is turned on. The limp-home mechanism must therefore be reset as described in “Resetting activated limp-home solenoid”.
