Some great work, can't be much left to do now. Apart from an exhaust 
and maybe a long list of other things as once you start, you can never stop!

Cheers mate, coming from someone who looks after their car as you do I appreciate that. There is always something though and I think Ant has set the seed.

I'd go for an exhaust next mate.
I have to agree, they do need a full refurb. Maybe before an exhaust even.

So, here's a first for this thread. An item entered in this thread the day it happened. After fitting the cabin display part of my reversing sensors a while ago and finding I had a Saturday afternoon to myself I thought I should get the sensors fitted. First job was to measure and mark out the height and spacing on the rear bumper. For this I placed a strip of 2" masking tape across the rear bumper at the prescribed height from the floor.
Next to cut the holes ready to receive the sensors. Be careful of the cutting tool that is supplied as they are fffffffffffffffffffairly sharp !!
Remove the tape and then reverse car onto some 2" blocks of wood so I could get my trolley jacks under the jacking points and raise the car up a bit. I'd never had the rear bumper skin off a Z4 till today so it was a bit of a learning curve for me. The rear arch liner is attached to the bumper by 3 plastic stud at each side at the rear of the arches. Under the N/S is 1 8mm self tapping bolt near to the exhaust (but not the one which holds the exhaust heat shield) and at the O/S there are 4, all of which need to be removed. Then, the bumper just pulls outwards from the front edge at the wheel arch, it simply clips in to some clips all along the top past the rear lights.
Only things connecting it to the car are the two reg. plate lights which un plug easily. Put the bumper to one side now. Now I needed to find an entry point for the cables from the sensors and at the nearside the nice people at BMW had kindly left an unused grommet which was perfect for the job. This may well be where the factory fit parking sensor wiring passes through into the car.
This where I decided to route the cables from the sensors and also where to mount the control unit as well, plus the "spare" cable.
While the bumper was off the exhaust tips looked in need of some TLC.
And then this,
Would've been rude not to ............................
After that I placed the sensors in the holes in the bumper, A at N/S Outer, B at N/S inner, C at O/S inner and D at O/S Outer, the reason for which will become clear soon. After fitting the sensors and routing the cables to the N/S I tidied them up by securing them to the centre two sensors with a couple of cable ties.
Having fed the cables through the grommet I lifted the bumper back up and fed the reg. plate light wiring through the light appertures, continuing to pull the sensor cables through into the car then finally clipped the bumper back into position and fitted the plastic studs and self tappers. Where the plastic studs fit.(3 on each side of the car)
The studs. You pull the centre "pin" out then the main part, refit in reverse order.
Next, the connections in the car boot. Found the power wire for the reversing lights and spliced a feed for the control box from that and made an earth for the ground cable. The 4 sensor were connected in reverse fashion A-D,B-C,C-B and D-A. The reason for this was that I had mounted the display under the dash upside down. Tidied up all the wiring and replaced the trims and covers in the boot. The finished article looks like this,
This is the display when you've reached the point where you don't want to go any further.
A very satisfying afternoons work all in all.
Tony.
ps. If you haven't got one of these, do yourself a huge favour and get one In conjunction with a 1/4" drive socket set such as this they're invaluable on a job like this.

Looks like it came out of the factory with them, nice work.
Great work mate and an excellent write up,
have you thought about an exhaust?
