I know how Wernher von Braun felt at times…sometimes you don’t realise how far you’re in…

Haven't driven it since early November, so I gave it a good wash and took some photos ready to put up for sale.

Unfortunately now it's all shiny, and I've remembered how much I enjoy driving it, I don't want to sell it :rofl:

The rubber brake line hoses that connector the calipers to the metal lines are proving a bitch..

After 5 days, countless blow torch and penetrating fluid only one released ..the others just won’t move..bit the bullet and ordered fresh stainless steel ferrules and I’ll remake the junctions ..

Fitting stainless steel braided hoses ..wish I hadn’t started..

These pipes are only just over 3 years old…

Great strategy …steel parts with alloy pipes ..talk about galvanic corrosion

Fitted the two radar units for the ID4Motion digital cluster to enable blind spot monitoring..

Fit nicely in the slots thoughtfully provide by BMW on the internal bumper mounts..

Fired them up today…can’t get a ‘blind spot’ warning to come up on the dash..maybe need to be out n about with big bits of metal near by..current draw on the units so they are alive..

In the process found the RHS rear wing has been resprayed as over spray is on the internal bumper mount..

Makes a mockery of FBMWSH etc..number of ‘issues’ not recorded in any documentation… :tumbleweed:

My Saturday job was to upgrade my 676 amplifier, that I retrofitted last year, to a 677 system. New power supply, fibre optic and speaker adaptor looms were all made up and the system worked "straight out of the box" (** EDIT - after coding!!). The only downside is that the amp was from an E70, so although is the correct part the firmware isn't set up for the E89, so that's the next job to sort, but it is working as it should :thumbsup:

Will be interesting to see what happens audio wise as the inlets and outputs are hardwired but we’re driving different speakers in different locations.. :tumbleweed:

The only differences are that the E89 has the additional rear centre channel that I've added into the correct plug (four pin shared with the MOST), and that there is a minor change on the rear negative pins, but this seems to be working fine. So I just need the firmware update to match the E89 environment (Subwoofers in the rear and not under the seats, and the woofers in the front footwell instead of the rear 1/4 panel etc). On researching this, I should be able to sort this with ISTA and my ICOM. It's useable for now, just a little bassy, certainly works with the surround function :thumbsup:

Yes I was referring to the firmware with its assumptions..glad it’s worked out

I thought it was something to deal with the low volume to the outside when the standard amp was open, so I converted it to a Hi-Fi amplifier and set the speakers in the Hi-Fi set, the center speaker and the door, Twitter, rear subwoofer, and rear center speaker.
The volume at the time of opening was noisy inside, and it became so loud that you could tell that a car had come even outside.
I think the top Hi-Fi amp is 650W, but what about it?

I used 6P Brembo calipers on an AMG CLS63 before, and I was trying to increase the standard 360mm outer diameter to 390mm with an adapter, but I gave up because the caliper curve and outer diameter were just barely within the limits. Isn't 380mm too heavy for a steel plate?
Also, there are twin calipers for the rear, what do you think?
In Japan, you have to pass a vehicle inspection for structural changes, right?

I assume neither of these is fitted to an E89?

Purchased that luxon brace bar off ebay. Very impressed with it, super solid. Doesnt rub on anything which from their photos looked like possiblty the airbox would. Going to take her out on some twisties this weekend to give it a good run.
