Parking sensors

[IMAY2023]

Hi there!

C40 owner here and unfortunately my car only came with rear parking sensors.

I've been trying to gather information on what I would need to perform a retrofit to enable the front sensors!

I noticed I have blanks on the front bumper and will need a total of 6 sensors. I will need to drill the 2 side ones.

Can anyone chime in if they've done this sort of retrofit before?

I assume this should apply to all CMA platform cars (Polestar 2, XC40 Recharge, XC40)

Mainly:

• would I need another PDC module?
  
• does any one know if the harness has the connections already?
  
• part numbers for sensors and harnesses show a VP06 or VP07 variant... not sure how I can determine which one I have?
  

Thanks in advance!

You don't need any module, parking sensors are connected to CEM and controlled by it. 
On my 2019 S60 t5 momentum I had front and rear sensors. Total 8. I added 4 (2 on front sides and 2 on back sides) to have park assist pilot.  
If you want only front parking sensors without on the sides (without ark assist pilot), you'll only need front bumper harness with 4 sensors and wire it to CEM. 
If you want park assist pilot, you'll need 6 at the front. and add 2 at the back sides. 
Here is a guide for XC60 but it's same for all SPA cars.

Look at the front driver side behind the wheel cover, if there is already a harness on the bumper, that's where you'll see connector between bumper harness going to CEM. 
Each sensor has three wires. 2 of those are common and 1 individual going to CEM.  
Finding the harness and sensors is easy but Volvo no longer sells the replacement wiring in US (mentioned in the guide), so you might need to wire it yourself. Which I ended up doing. 
You'll need  30656698 Repair Terminal at least six of them. Those are for CEM connection. 

Good luck
