Removal/install front bumper (55, but its the same for all)

Yesterday I removed and reinstalled my front bumper . Maybe there is some interest in my findings. I did this as part of the process to install Distronic in my car, which is not finished with this exercise.

First, you need a lift. A column lift that leaves the front wheels free. The bottom engine protectors need to be removed and that requires a dozen or so bolts to be removed and removal of some of the fender bolts need to have the front wheels turn to the left and right to be able to reach them properly.

Second, the inner fender liner is held in place with those plastic male in female pressure thingies. I don't know the official name but these are a one time usage item. The chances that you'll ruin the male part on a car that is not brand new are very high. Partnumber is A1249900492 and they cost about 1 EUR a piece and you need four.
All electrical plugs have a gray locking mechanism built into them. This needs to be lifted first about half a centimeter before any plug can be unplugged.

The work:
First step is easy: remove the two bottom engine covers by removing all the bolts you can find. Start with the one on the front. I think there are about 16 or so. In the middle where both covers meet the (two) bolts hold both of them. When all bolts are removed the covers fall off. Unplug the plugs to the daytime lights.

Second step is removing the aforementioned plastic thingies that hold the liner to the bumper and fender. Four of them, two on each side and you will need to turn the wheel to get better access. They sit on the outside of the fender. Once removed you can push the liner inwards which will open up your view to a guide rail which ties the fender to the bumper on the piece directly behind the headlights. Unplug the plug from the fender to the car. Its on the right fender. Twist the complete plug about 45 degrees and it will come out its bracket making it easier to unplug it.

Third step: remove the four 10mm bolts from the guiding rails, two on each side. Use a 10mm socket on a long extender (30cm or more).
The front part of the bumper that was tied to the fender shows play now (don't start tearing at it, it's still in a guiding mechanism on the inside).

Fourth step: remove the four 8mm bolts with black heads that are under the hood on the front which hold an adjusting mechanism that adjusts the play between the nose and the hood. Just remove the bolts.
Using a flat head screw driver push the catches that dig into the adjusting mechanism towards the front, freeing the nose from the car.

Now be aware that the bumper is free. It is held in place with a sliding mechanism on both outer sides behind the head lights. Ergo: slide the bumper towards the front and it's off.

Obviously install is the reverse of removal. Wait with the four black 8mm bolts until the sides are fixed in place with the 10mm bolts. Only then you can determine the gap between the hood and the nose to make it even everywhere and tying down the four black bolts.

All in all it took me 3 hours with a helper (removal and install), but I did some ' Distronic' work by installing a new loom inside the front bumper and two radars. And I had to be creative to include four new wires into the existing plug that ties the bumper to the rest of the car electrical wise. So it may be done in two hours.
Rear bumper took me one hour on and off. (four hands)

Sorry no pictures. No camera available at that time. Maybe I'll shoot some of the details later.

Judge, I didn't realise that Distrionic could be retrofitted, presumably the parts a likely to be very expensive and require coding?

Yep and Yes.

You want a list?
2 small range radars in the front (215 EUR each, used)
2 Brackets (7 EUR each, new)
1 long range radar in the front (550 EUR, used)
Bracket and nuts for the long range radar (20 EUR, new)
Wiring harness rear bumper (92 EUR )
Wiring harness front bumper (110 EUR )
Wiring harness distronic controller (10 EUR )
DTR controller (217 EUR used)
ESP controller (1362 EUR, new OUCH!)
Steering wheel mantle with appropriate handle (450 EUR, new)
MB emblem on the nose (136 EUR new)

Programming through Stuttgart and my local friendly one. EUR ? yet to be determined.

And quite a few hours from my time to get to the appropriate parts and install this stuff (which is not yet done).

Mind you this system works together with the blind spot assistant (the DTR controller takes control of the rear radars too) It should be possible to have it working without the BSA stuff, but its a challenge.

Additional bumper removal details & pics

Just removed my front bumper (needed refinishing) and thought I'd add a few details and pics based upon my experience in the interest of supplementing this already solid writeup.

There are 2 nuts hidden from view behind the lower center grille that hold the bumper to its support; easily viewed once lower grille is removed (be careful, outside temp sensor is installed into this grille).

Also, the two connectors for the fog lights are zip-tied to the bumper, they also need to be removed.

Hope this helps!

It certainly helps, but this is the R172 section, and you are talking/showing about an R171 front bumper
