The electronic throttle on my 1999 9-5 failed. I purchased a replacement part and want to install it. Looking at the part, it appears fairly straight forward - unbolt the old part, remove the hoses and wiring and replace with the new part. Is there anything I should be aware of? Any help would greatly be appreciated.
Thanks
John

Yup its pretty much plug and play!
Remove fuse 17 for a few minutes once limp home has been activated, this will clear the codes, then you can reset yourself!

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 to the OFF position.
2. Remove the engine cover.
3. Undo the coolant expansion tank cap to release any pressure and then retighten it.
4. Remove the cover on the throttle body pedal arm.
5. Pinch together the 2 coolant hoses to the throttle body.
6. Undo the charge air bypass valve hose and the two preheating hoses.
7. Detach the lower vacuum hose.
8. Undo the turbocharger delivery pipe retaining screw in the cylinder head.
9. Undo the hose clip and carefully tilt up the turbocharger delivery pipe.
10. Detach the accelerator pedal wire from the throttle body pedal arm.
11. Lift off the rubber seal and unplug the limp-home solenoid connector.
12. Unplug the throttle body 10-pin connector.
13. Undo the 3 throttle body retaining screws.
14. Lift up the throttle body and detach the hose under the limp-home solenoid.

To fit

1. Position the throttle body and screw it on with the 3 retaining screws. Fit a new seal if necessary and lubricate it with a thin coat of vaseline (part no. 30 20 271).
2. Fit the hose under the limp home solenoid and fit the clip.
3. Tighten the 3 throttle body retaining screws.
4. Spray the throttle body 10-pin connector with Kontakt 61 (part no. 30 04 520) and plug it in.
5. Spray the limp-home solenoid connector with Kontakt 61 (part no. 30 04 520). Plug in the connector and fit the rubber seal.
6. Fasten the accelerator pedal wire to the throttle body pedal arm.
7. Fit the lower vacuum hose.
8. Fit the charge air bypass valve hose and the two preheating hoses.
9. Remove the clips on the two coolant hoses to the throttle body.
10. Fit the cover on the throttle body pedal arm.
11. Start the engine and make sure all the connections are tight. Top up with coolant as necessary.
12. Refit the engine cover.

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 triggered limp-home solenoid”.


Resetting triggered limp-home solenoid

1. Remove the engine cover.
2. Put the ignition in ON position.
3. Connect the diagnostic tool and contact Trionic. Clear the diagnostic trouble codes.
4. Put the ignition in the OFF position and wait 10 s. Remove the cover over the throttle body.
5. Carefully push the end of the spring towards the throttle body.
6. Rotate the black tooth disc anti-clockwise with a screwdriver. A click will be heard in its end position.
7. Rotate the pedal arm clockwise.
8. Make sure the throttle arm does not follow with the pedal arm when it is rotated.
9. Fit the cover to the throttle body.
