Default Westfalia Trailer Hitch install on E46 M3 DIY

Disclaimer: This is more of a description of what I did to my car to be used as a guide, than a true DIY so if you attempt this it is all on you!

After finally finding a solution in the factory Euro hitch from Westfalia for the E46, I went ahead and ordered one from Europe. I tried to buy it from a place in the states called but they didn't respond to my inquiry until after I had already had the hitch installed on my car (two months later stating it was 6-8 weeks, and $650 + shipping). I got it from a BMW parts online store in Denmark here:

It took a week to receive from the time I ordered it, and cost me less than $500 delivered based on exchange rate at the time.

So here it is spread out on the floor... this version does not have the included electrics, but the M3 is not pre-wired anyway so it is better (why pay extra for something you can't use?).The quality of the components was better than I expected, very solid and Germanic precision was evident in every aspect from the welds, to the machining on the tow ball latch mechanism, and quality powder coat (the stuff that looks like scratches it sticker residue I didn't bother to remove). Much better than anything I could have had custom made.

OK, remove the rear bumper: I jacked the car up and removed the wheels to make it easier to work on but this is optional.
Remove the lower valence; remove plastic pop rivets on bottom edge:

Then yank up and out to get it off:

Remove fender liners on both sides:

Now gut your trunk if not already done. You will need to take out the floor mat and the side carpets to access the bumper bolts inside.

Remove the 3 13mm nuts on both sides, these are the studs holding the bumper on:

Then pull the bumper off, it is held on with a clip in the inner fender, with a guide on both sides here you can kind of see it, behind the fender liner:

It isn't heavy but it is large and somewhat flimsy, I did it alone but I have a long wingspan... it would be easier with a helper just to make sure you don't drop anything
