I couldn't find many guides for this online, and ended up taking hours stumbling through it and sourcing the right tools, so I hope this helps.
Parts needed
• Cruise control stalk: 99761326100 - I sourced a used part in the US for around $120
• Wiring loom: 99762267400 - around $50 new from a Porsche Centre
• Fixing screw: N90906801 - around $4 new from a Porsche Centre (only one needed)
• Steering column cover: 99755247503 - around $250 new from a Porsche Centre (optional, you can modify your existing one - instructions below)
Tools needed
To fit:
• Foam tape
• Long-nose pliers
• T10 torx screwdriver with at least 50mm length (my original was too short)
• T8 torx screwdriver
To modify the original cover:
• Junior hacksaw
• 35mm hole saw
• A drill
• A nail file
Fitting the stalk
1. Position the steering wheel as high and close to you as possible.
2. Use the T10 torx screwdriver to undo the 3 screws on the lower steering column cover:
3. Pull the upper steering column cover upwards, and pull the lower steering column cover downwards and out towards you. A wiring loom fixed to the cover will prevent you from pulling it all the way out.
4. Use the long-nose pliers to compress the fixing and push it upwards. This can be tricky - just make sure you have the pliers on the wide points of the fixing. It should just pop right out.
5. Wiggle the steering column cover out from underneath the steering wheel. It’s a bit awkward, and you’ll need to move the steering wheel adjustment lever around to get it out.
Here’s how that wiring loom fixing looks:
Before the next step:
from the factory, two screws are fitted to the cruise control stalk. To fit the second screw, you would need to remove and refit the steering wheel and airbag.
I tried to fit with only one screw, but wasn’t happy with the amount of play on the cruise control stalk. However, you can remove all play by adding a small piece of foam tape to the stalk, as shown below. It’s completely solid and doesn’t budge with this setup.
This means there is no need to remove and refit the steering wheel and airbag, which carries some risk and takes a lot of extra time.
6. On the cruise control stalk, there is a small tab that locates into the steering column. Get a feel for where this locates, then add a small piece of foam tape to remove any slack.
7. Use the T8 torx screwdriver to tighten the screw (red circle), and insert both ends of the wiring loom (yellow circles):
Modifying the lower steering column cover
The goal here is to mirror the shape of the cutout on the other side of the cover. Note that the hole for the upper stalk has a diameter of 38mm, whereas the hole for the lower stalk (that you are cutting) has a diameter of 35mm.
8. Place the steering column cover upside down, and draw vertical two lines perpendicular to the surface, from the edges of the hole (red lines).
Then, measure the position from the flat surface to the top edge of the existing cutout, and mark it on the side you would like to cut (yellow line).
9. Take the flat side of your 35mm hole saw, position it between these lines, and draw around it. Mark the centre point inside this circle.
Your markings should finish looking something like this:
10. Drill a small pilot hole directly through the centre point. Then, take your hole saw and begin cutting.
We did this by hand, without the drill, so as not to damage the plastic. It took about 15 mins to cut through the plastic.
11. Take your junior hacksaw and cut along the straight lines that you drew earlier.
12. File down the edges (a nail file works perfectly…) and put some ‘back to black’ plastic trim restorer around the edges.
13. Refit using the reverse of the above steps: position the steering wheel high and close to you, maneuver the steering column cover in, push the wiring loom fixing (that you pushed out with the pliers) back into place, get the upper and lower steering column covers in place, refit the three torx screws underneath.
Congrats, you’ve saved $250 on an OEM steering column cover!
14. Get it coded at your local independent (my Foxwell tool was unable to code it in, unfortunately). Some independents get this step wrong, it needs coding in 3 places:
• DME
• Instrument Cluster
• Steering Wheel Electronics
If the cruise control indicator doesn’t light up on the dashboard, it hasn’t been coded correctly. My indy coded it right first time - they charged $120. There is no 'access code' required - that's for the 981 generation onwards.
I hope this helps
Wonderful writeup! Congratulations on achieving the Technical Excellence award with your 7th posting! I'm heading back to check your other posts!
