I just put the renewed tags on mine as well. And discovered an issue while putting the registration slip away; noticed that one of the window switch lights wasn't lit, so I tapped on it (because that's the first step of troubleshooting) and the window moved! :shock:

The key was in my pocket, so I don't think that's supposed to happen. :?

Looks like I have some troubleshooting ahead of me.

Au contraire. Even US cars were wired to allow key off window operation with the drivers door open if you retrieved some wires and plugged in a relay. I would guess euro cars came that way stock. I think it was RonW who figured that out way back when and posted about it. Might have even been in the Roadfly days.

Dave, my M535 does this as well. Window operation with key out and door open.

Well now... I learned something new today; thanks, guys! I guess that means I can go home now. ;)

But I still have some troubleshooting to do on it; something on fuse 5 is making the battery go flat if its left for a couple days.

Probably the interior lights relay.

@ 186k
Replaced factory clutch - resurfaced flywheel - associated seals.
Replaced factory starter while in there...with a 1990 535

Flushed brake & clutch tar, er fluid.

16" Style 29's went on this fall...went form 225 on the M5 rims to 205 on these. And summer to all-season tires...much plusher ride.

Pulled all the Heyco tools from my trunk one-by-one and cleaned up any light surface rust with some steel wool. Then I wiped them with a thin coat of Birchwood Casey "Rig Universal Gun Grease" which had been suggested by someone in an older thread. Did the same with the tools in my E24.

It's a light grease that's mostly used to prevent rust and corrosion in firearms so it should be pretty effective. I have a hunch it offers better protection than WD-40, but we'll see.

This weekend I started to disassemble the whole rear end. Now I know what spending most of its life in NJ means! It was supposed to be a simple rear sub-frame bushing replacement (I've had the Powerflex for like 8 years now!) but after looking at the rust on everything (plus the two "pins" don't want to come out but that's another story) I decided to bring it all down take it all apart, clean it up and make it look pretty. I'll be ordering all parking brake stuff, backing plates, bearings, rotors, pads, dog bones and axle shafts. Also need to clean and seal the differential as it looks wet. I replaced the exhaust with a Boysen seven years ago and its rusting so it also needs clean up and painting. Driveshaft was replaced about three years back also. We'll see how deep the rabbit hole is! I'm going to try Eastwood's 2K Ceramic Chassis Stain Black on the components.

I installed all new steering column switch-gear. What a huge improvement to the driving experience. I hadn't realized how worn the old switches were and how sloppy all of it felt. I used NOS for the wipers and turn signals-couldn't find any for the cruise, so I used the new part number. Among my favorite updates so far.

Wow, interesting. Now I have to go pay attention to how sloppy mine are. Never considered this. Thanks!

Replaced the dog bones on my lunch break. They were so worn out you could use them as hot wheels! Wonder if they were original...

Installed sport seats I just recovered using the kit from Lseat. Took longer than I wanted to as there were so many things missing hardware wise from the seats to begin with, and having to repair a split in the bolster.
Turned out pretty good as this was my first time even attempting anything upholstery related and quality of the material seems similar to the leather from my e92. Also painted the rear parcel shelf black as it was a faded light blue with vinyl fabric paint from AutoZone.
Oh and also added LED interior dome lights so they become actually useful at night
