Parking Sensor Xref

[Joe558]

I'm gathering parts to add Park Pilot Assist to my 2020 S60, but what I'm hung up on right now are the side sensors for the front, I believe they are part number 32209360. These seem to be near impossible to find used and I don't really want to spend ~$200+ for these two sensors. Are there any other part numbers that we can use in place of these sensors? There seem to be quite a few different sensors among the various models and locations, I was hoping one of the others may work?

I retrofitted them officially via VIDA. I used this   the part number "32204952"   is the kit. Which was supposed to come with  harnesses but it turned out the kit had not included them anymore by the time I purchased it. So, I got everything but the wiring.  

All I can tell you is this, front and rear sensors are different and their connector is also different. 
I checked the part number of the front side (outer) sensor part number "32209364" that's the one I got with the kit. Sorry, I could not check the rear outer ones because they are not easily accessible.  

I can give one tip. DO NOT buy the cheap ones from ALiExpress, they usually do not work either they faulty or simply wrong side.

Hello. Did you find a solution for alternative sensor numbers?

I used sensors from AliExpress (exactly this lot) and they work just fine. Much cheaper and always in stock. Used them to add front parking sensors in my Volvo XC90 MY2016 (wiring was done by myself, just 4 separate 3-wire cables from the front bumper to the CEM). They should have the side sensors in stock too.
