    4. Follow the sensor connecting cable and undo the clip on the water pipe.

    5. Detach the connector from the holder.

    6. Unplug the connector.

    7. Change the sensor.

    To fit

    1. Fit the sensor provisionally so that the cable runs along the water pipe. Change the O-ring if necessary and lubricate it with engine oil.

    2. Spray the connector with Kontakt 61 (part no. 30 04 520), press together the connector and fit it in the holder.

    3. Secure the cables with the retaining clip. Take care not to pinch or damage the cables with the clip.

    4. Press in the sensor and screw it on with the O-ring fitted together with the heat shield. Make sure the O-ring is positioned correctly so that the sensor bottoms in the engine block. Otherwise, there is a risk of the sensor mounting lug breaking off.

    5. Lubricate the screw for the exhaust manifold heat shield with Molykote 1000 or equivalent (part no. 30 20 271) and fit the heat shield.

    Tightening torque, nut, heat shield 20 Nm (15 lbf ft)

    6. Start the engine and check for oil leaks.

    Getting the Torx30 screw out proved to be a very difficult task. In order to get the bit into the screw correctly, there's only a limited amount of room before you run into the downpipe. I tried a flexible ratcheting extension, an elbow extension, and neither worked as I couldn't get the bit to stay in the screw head. After three days, the only thing that worked was my wife's small hands getting down there and using ratchet that allowed the bit to sit all the way through. Similar to this:

    Great write-up!

    New owner of a 2003 9-5 3.0t Wagon with 83k miles that is in fantastic shape - The previous owner did every single service/repair the dealership recommended. The CPS was already replaced once by a dealership ~30 k miles ago. It seems to have a minor hot start issue (have to cycle the key on/off 3 times before it starts - first two times it just cranks). I'd like to see if the CPS is going bad again. Is this the same procedure I'd use on the 3.0t? Also, beyond the Torx 30, what other tools do I need? Thanks in advance.

    Access that torque from the bottom easily going up at it. Use a standard snap-on (or craftsman) T30 socket and either a stubby 3/8 ratchet or a fine tooth flex head long ratchet. Total job should not take more then 45 minutes in a driveway with ramps.

    Thanks Burnsside42. Very helpful. This seems like such a common issue, it might not be a bad idea to have an extra CPS and appropriate tools in the spare tire compartment.
