A6 Allroad Rear Bumper Removal (How To)

21 posts in this topic

This morning I replaced a rear parking sensor and in the spirit of giving back (I've taken a lot from the forum so it only seems fair) I took a few pictures to help others who might need to remove the rear bumper from their A6. My car is a C5 Allroad but I guess these instructions will be good for regular A6 avants and possibly saloons as well.

Firstly, thanks to Scotty for checking the fault codes with his VAGCom and identifying which sensor was faulty (inner right)+++

This will take a couple of hours and you will need a socket set (with deep sockets), torx drivers, cross-head screwdriver and a torch.

The first thing to do is to remove the AV carrier which is secured by 8mm hex bolts. The arrows in the picture below are pointing to hidden bolts, there are 5 in total.

Once the bolts are removed the carrier comes out with a bit if wiggling and the CD player can be unplugged so you can get it right out of the way.

Next the 10mm nuts that secure the bumper to the body need to be removed, there are 5 each side and they are tricky to get at so a grab tool is handy. Once again the arrow is pointing to a nut that the camera couldn't capture in this shot.

The grab tool is needed to finally remove the nuts on the left. If you have 8 inch long fingers then you won't need the grab:p

Next remove the screws under the bumper, there are 4 in total and the picture shows the pair on the left side. The big plastic screw does not need to come off.

attachment.php?attachmentid=36596&stc=1&d=1246799464

Finally there are a couple of torx screws in the wheel arch (if you have an Allroad putting the suspension on it's highest setting helps access). First remove a couple of torx screws that secure the wheel arch liner.

attachment.php?attachmentid=36597&stc=1&d=1246799479

You can now get at the screws that secure the leading edge of the bumper, you only have to remove the two small ones that are circled in the picture.

attachment.php?attachmentid=36598&stc=1&d=1246799493

Now the difficult bit, the bumper clips to the body and the only way to get it off is to grip it firmly and pull up and out and the clips will release. It feels brutal and make a horrible noise but it works!

attachment.php?attachmentid=36599&stc=1&d=1246799504

Now the bumper can be removed, put a blanket or towel down so it doesn't get scratched. The picture below shows the bumper about to come off and you can see the outer 3 bolts.

attachment.php?attachmentid=36600&stc=1&d=1246799517

If you have parking sensors take care not to strain the wires which pass through the body on the left side as you lower the bumper to the floor.

As the say in the Haynes manuals "reassembly is the reverse of the above".

I hope that someone finds this useful. If anything is not clear please post your comments and I'll add more detail.

Thank you Simon. Trying to install a hitch on my allroad I was stopped dead in my tracks at the bumper clips. Even after I read your instructions it was difficult to commit to yanking hard enough to pop it out of the clips. I never would have figured it out.

Excellent, thanks. I've been looking for this procedure for some time. Guess what, I also have dead sensor which I need to replace.

I kindly ask for permission to translate and publish this procedure on Czech Audi forum audiklub.cz.

I don't mind but you should check with one of the moderators.

This is great. This job is not even explained properly in the ELSAWIN dealer manual. It obviously works for the Audi A6 Avant bumper removal too - I have A6 Avant 1.8 TDI. What fooled me was that the two inner nuts were covered by felt glued to the metal. Now I have pulled that off there they are! I got a tubular spanner set off ebay for £4 which do the job fine.

I have also bought the sensorless PD1 of Amazon. Intend to come back and report once it's wired in.

Thanks again Simon.

Just like to say thanks to Simon690 for his excellent guide.

I've been a truck fitter for 25 years, and I'd found all screws mentioned, but still could not shift the bumper, thats when I thought time to look on the net, and found this guide.

Those clips are unbelievebly strong! Took almost all my strength to pull it off!

One thing I will say, is that if your changing just an outer sensor (like I was) then you only need to remove just the one side. On the opposite side to your faulty sensor slacken the 3 + 2 internal bolts, and remove the two screws from underneath, should be ok to leave the wheel arch screws tight. Strip down the side with the faulty sensor as per instructions.

Also if you don't have a CD player in the AV rack then no need to remove that.

Once again, thanks for the guide, without it I would have been pulling my hair out, as I had already tugged very hard on the bumber, but it needs to come outwards from the side, not slide bakwards as I had thought.

Now to put it back together, and of course hope the sensors work!

Just wondered if anyone had experience of doing this and has encountered the Bose amplifier on the right hand side, there's not mention of the bolts on the opposite side of the AV carrier. I don't think removal will be a physical problem, but don't you have to 'reactivate' the bose if you disconnect it?

Also, when the description says the bumper is clipped to the bodywork, is this all around or just adjacent to the wheel arches as pictured?

Will be ordering a new right rear sensor on Monday!

Urgh. Stealers say that it will need to be painted. Not mentioned here so I'm hoping they're wrong, or that I can just get a touch up / aerosol. The part's £80 alone! Will let you know how I get on.

Okay, got the part. Audi counldn't offer an aerosol or touch up so spoke to my local body shop who are going to spray it up fpr a tenner. Will get it back next week and think about fitting it next weekend. Also found out that the driver's door microswitch is shot. Yet another thing to sort....

Done! Job cost £80 for the part, plus £10 for spraying. Personally, it was about 2 hours of labour. Just thougt I'd share a few tips/observations from my experience of the job...

1) Bose subwofer on right hand side (if you have one). Remove the metal box only (two nuts), you can leave the plastic woofer box in place and still get sufficient access. You don't need to reactivate the Bose afterwards.

2) The 'pulling out' and 'horrendous crunch' is just from the bumper section adjacent to the wheels. Wasn't too bad for me, just a brave tug!

3) Make sure you feed the bumper section adjacent to the wheel back into position carefully, starting from the rearmost point to ensure a good fit back into position.

4) A set of deep sockets is very useful.

Good luck folks. Do post if you have success too.

I have just fitted rear parking sensors to my '08 plate A6 Allroad and the fitting arrangements are somewhat different to previous models.

There are only three bolts on each side to remove instead of five - all are easy to get to and don't need grab tool (just long10mm socket) - see picture.

Three screws underneath where stainless scuff plate fits to bottom bracket and three screws in wheel arch where the mud guards are attached. There are also three push in snap connectors either side too - but easy to remove and replace, nowhere near as difficult as previous versions.

Also worth noting that the bumper is already configured for parking sensors and clearly marked for drilling.

Attached a few useful pics.

I changed one of my 2002 Allroad rear sensors in March 2011, and now the rear ones are playing about again, with a constant beep. Anyway I managed to track down some sensors on Ebay, apparently original Audi parts, so I chanced my arm and bought 3. They arrived today, and they certainly look like Audi parts.

Inner sensor 4B0919275D and outer sensor 4B0919275A and the seller for when the links expire is oem.sensors.euro, and the price, a bargain £22 each.

Once fitted I'll come back and update the thread - now I've refreshed my memory on how to do it, but it probably won't be for a while.

Just fitted my new sensors as per above post and they work a treat, took 2 hours start to finish, although that did entail a bit of standing around chatting and removing the air tank to retrieve my dropped socket - at least I also retrieved the nut I dropped last time :-)

Hopefully now that's the end of my constant beep as soon as reverse is engaged, certainly seems to have fixed it.

Thanks

Thanks Simon690, excellent description to help me fit a tow-bar to my 02 Allroad wagon. If it helps I found it easier to remove both tail light assemblies (I was worried they might be damaged in the process) very easy to remove, and it also gave me an excellent view between the body and the bumper bar of the 5 x bumper bar bolts that go through the body.  Also as a writer previously mentioned when pulling down really hard on the sides of the bumper bar, I found that if both sides were pulled outwards more so than down it released very easily, due to the way the sides of the bar clip into the body molding. Cheers thanks Mate !!

Another excuse for 'Holy Thread Resurrection Batrman'.

 

But in a good way, as it was a helpful one.  +++
