6C Cross Polo Parking Sensor Retaining brackets

[2226]

How are the rear PDC retaining brackets attached to the bumper? Glue or tape?
Can they be re-used?

I have 4 different required parts:
6R0 919 491 D
6R0 919 491 E
6R0 919 492 E
6R0 919 492 D

This is for 2JK option bumpers.

I don't even want to think what the dealer will ask for these.

A 2nd-hand bumper finally showed up in the correct colour (no need to paint), and it's in good shape, but it wasn't optioned with PDC.
I'll need to transfer the retainers to hold the sensors.

I know I need tool BEA000001 which is a 18mm punch tool. Not going to find that here, so it's going to be a temu special for that or I'll pay more to get the official tool than this bumper is going to cost me.
It's just the retainers that I'm worried about.

I have been looking for a replacement rear bumper (and the stiffener) for probably 2+ years now.
Was rear-ended by someone while I was turning. The bumper stiffener took the hit (needs replacing), the bumper has the slightest crease and a crack. The bootlid was dented along the edge, but I swung a dead blow hammer at it and it restored perfectly. Apart from the crack in the top part of the bumper you'd never judge how hard the hit actually was.

I retro fitted front parking sensors to my 2011 Audi S4 maybe 10 or 11 years ago, it was VW Passat outer retainers that I bought (the inner 2 of that car get fitted into the grill using a different type of retainer).
At that time, I'm sure that VW Group sold the double sided sticky tabs separately from the retainers, but I felt the need to fix them "properly" as one of the rear factory fitted sensors looks to be "not quite perfectly fitted". So, I bought a version of Araldite that was grey and claimed to be a structural adhesive - that worked well!
I'm afraid that I emptied my wallet on a kit of bits to do that job, which included both VW Group punch sizes, mandrels and clamps to locate the retainers and hold them in place while the adhesive set. It cost about £90 10 or 11 years ago - though hopefully there is now a cheaper version available via Temu direct from China!

Edit:- hopefully your bumper that you have bought has the parking sensors locations moulded into it - very handy!

Yes, hoping it does have the location markings. I think they all do. Otherwise will do some very careful measuring and marking.

Worst case I carefully pry the retainers off the current bumper and just glue them in. Not sure if the factory tape acted as a seal or just adhesive.

I guess I'll see what is needed once I pick up the bumper this week.

These bumpers don't show up often here in Cape Town. At least not in white. Plenty on the other side of the country though, but courier charges these days are through the roof.
Need to grab this while I can.

I don't mind buying tools when there's a job to be done if I know I'll use the tool again. The required tool here is not one of those tools.
I can actually get the exact copy of the tool from aliexpress, but even then it costs more than the bumper.
The other options on AliExpress and temu seem to do the same job, but the cutter is a flat-edge cylinder while the actual tool is a waved edge. Will probably work the same and it'll cost me GBP5,00 instead of GBP40,00. I've seen the tool on other sites for as little as 13 Euro, but 60 Euro shipping. Can't win.

I think that lots of people just use a drill to cut these holes, but while that will work well with the older version of parking sensors that have a "trim" that fits in to cover that mess, it will not end up looking "as factory" if done while fitting these later parking sensors.

The punch method works better by dragging in a small bit of the bumper outer skin - to leave a perfect looking job.

I think that one thing that I discovered back 10 or 11 years ago, was, that VW only provide one version of the "seal washer" that slips on over the parking sensor, where as Audi provide 2 or 3 different versions that are intended to match the bumper colour closer than the basic black ones - but that should not be an issue for you as you will already have these parts from your original bumper.

I'll see how the temu tool works out.
Playing the usual temu game of waiting for the price to near worthless then I'll purchase.

So here in South Africa the large super market chains have teams of delivery drivers on single-cylinder motorcycles.
Did you know, that certain small single-cylinder engines trigger the Polo's PDC?!?
I kid you not. They don't have to be anywhere near the sensors, they just need to be noisy.

Ah man, why is nothing ever easy.

Picked up the bumper for a bargain 29.00GBP, but it's going to need paint.
Turns out it is pearl white and not plain white. Has a slight bit of paint/plastic crazing on the sill, but better than a crack on mine.
Middle black part and lower silver part can be swapped with mine as this has scuffs on the black part.

Was hoping to avoid paint, but 1/4 the price of everything out there and available, can't complain.

Unfortunately, looking around the back it does not have markings for the PDC sensors. Will have to measure, mark and make a template off the current bumper.

Temu hole punch is on the way. Paid 4,00GBP for it. Pointless, really, since I need to paint, but at least it will be a decent hole (hopefully).
