This may seem like old-news; but having trawled & trawled through threads, I must say this seems to be an obscure topic.

I'm not saying it's never been done; just that it's never been done properly. (no offence to those who have tried)

I had an understanding for instance, from what I've read on here; that there was maybe 8 fixings..?


In actual fact there are 14.

4x M6 Torx (T30), 4x M6 flanged nuts (10mm) & 6x Philips-head self tappers (No.2)


I nearly have all the photography and will be doing a guide shortly...

Good stuff. On the 145 there are just two bolts. On mine at least!

Think you have some missing mate! There should be 4 or 5 torx bolts on top of bumper with hatch open; 4/5 of same underneath; 2/3 screws each side inside wheel arch (attaching arch liner); 1 bolt each side going up into 3/4 panel which can only be seen once arch liner removed. At least as far as I can remember, its a while since I had mine off

sorry about this.

I was so pleased at the time with the success, and so busy with what had to be done- and so aware of the mainly 145-interest on the forum; that I never came back to it...

I will dig the pictures out of Google-drive, in the next couple of days, but I do have two to hand

One is all the types of hardware and tooling required, and the other is the blanking grommet that needs to be removed on either side against the rear-wall (rearmost part of the car) in the boot to access to the two M6 flange-nuts.
Apologies as the tooling image hasn't fully downloaded.

ok!

So, to remove the back bumper on a 146: do the following-

*lift the carpet in the boot, to identify the rearmost luggage-net tie down points. Next to these (one in each corner) is a rubber blind-grommet. Remove this, and use a 10mm / M6 socket to slacken, but not remove, the two flange-nuts within.
-The primary fixing for the rear bumper, is a bracket on either side which, attaches to the rear of the car, both in the boot, and under the wheel well, with a total of four M6 flange nuts. (2 in each bracket)


* now, working in the internal rear-three quarter panels, behind the rear wheel arches, pull back the carpet (on the OS, get in behind the alarm) and identity the Torx headed bolts that pass downwards from the body into the top of the bumper.
There is one on either side.
Use a Torx T30 to remove these.

* now, it is not necessary to remove the rear arch liners, but it might be worth removing the rear wheels to allow tooling to access the three self tapping screws on either side, which pass from the rear-bumper-arch-lip into the arch liners.
Working in the rear arches, outside the car, use a No.2 pozidrive screwdriver to remove the three self tappers from each side.

* with the three pozidrive arch-liner screws removed on each side, slacken the fit between the top of the arch-liner and the top most part of the bumper wheel arch (also the most forward part of the bumper) and identify a further bolt; passing upwards through the bumper into the bodywork. (This is almost behind the fuel filler on the OS)
I 'think' it is another Torx T30. There is one on either side. Remove these.

* working under the car (you do not need to Jack the car- I achieved this with the car on its wheels) identify two M6 / 10mm flange nuts which hold the rear bumper onto the chassis, underneath the spare wheel well.
These pass through a 'buttress' which spans the width of the car underneath. Access to the NS flange nut on the NS is slightly compromised by the exhaust bracketry, but the nuts face the same way as the ones previously slackened in the boot above.

One of these flange nuts DOES appear in the third attached image, of the buttress; low down towards the left.

Using a 10mm socket, remove these two flange nuts.

* return to the boot above, to remove the two slackened nuts (next to the luggage net mounting points) -take care not to lose them in the gap.
The bumper is now free- and can be withdrawn from the rear of the car; take care to remove the two connections to the number plate lamps as you lower it to the ground- preferably onto some cardboard - or a massive carpet of leaves.

Please see attached images.
