Rear parking sensor and bumper trim question

[ips]

hello all, I have a faulty rear parking sensor to replace and was wondering how easy it is to remove the bumper trim as i cant access the sensor without doing so. Incidentaly luckily i know which one it is as the main dealer diagnosed it whilst in for another job however i dont have the part number which is another question...does anyone know the part number ???
Many thanks

Never had the rear off myself on my B9, although I did briefly look into it as I was going to fit a tow-bar for a small trailer to take garden waste to our local recycling centre before my local authority starting charging if you had a trailer, so I never got around to it. For what I remember there were a series of bolts on the underside [4?] which will no doubt be corroded on   and then screws along the top/inside of the rear bumper that are only visible with the door open.

Part no is 6590EF, but please double check it on Catcar.

You can reach at least the corner sensors w/o removing anything on std bumper, dunno about XTR though. The sensor is held by two tabs. Pry them very carefully, I broke one tab despite heating the surroundings for a while.

If you opt for removing the bumper, there is a video on Youtube. https://youtu.be/61FoRNMrhX8?si=nLJcdz4xewkOUyaC

Last words, I did replace the same sensor twice. On first attempt I was too cheap to buy OE brand but relied on Hella being good enough. Mistake, it was warning constantly when below freezing temperatures. Only after I replaced it with correct Bosch the erroneus beeping was sorted.

That's brilliant many thanks, most helpful. ?

UPDATE
It is possible to remove the centre sensors without removing the bumper even with a towbar rail, however it is not easy and has to be done by feel alone. You can just about get your fingers to the clips and push the sensor out with your other hand by going above the cross rail but be advised you need fairly small hands / fingers and have a degree of dexterity, oh and be able to suffer a bit of pain whilst carrying out this contortion trick because as I say it is mighty tight. 

I have cleaned it checked the wiring and sprayed WD on the pins then temporarily re-fitted it to test it just in case it was a wiring issue, it was / is an intermitent fault so time will tell....

It is by Bosch, part no...PSA9663821577 another part number on it which also seems to come up on various parts suppliers is 0263003587. Genuine part £65 ish however there are various compatible makes available ranging from £15 ish....But the best value I have found is a set of four with free delivery and free returns from amazon for £29  

I will report back in a week or so after I have fully tested the repair and or fitted a replacement .

well the aftermarket sensor did not work at all, put old one back on its back to intermittent ? i can only assume that the control box thingie knows when its aftermarket and shuts the system down ? looks like i need OEM bosh part

I replaced all 4 sensors in mine - system wasn't working and they're cheap enough so didn't both to track down the faulty one and just replaced all 4. Didn't need to remove the bumper either but it's tight underneath as you say. 

The system and sensors work fine but the fault code is still stored in the parking module. So every time I engage reverse I get the error beep and then it springs into life.

Did you replace with aftermarket or oem

Aftermarket ones. Check the connector as there’s different types.
