New, new pump threw an Inactive Suspension code. Popped on my computer with INPA and the pump would not work when I tried to activate it.

Took it apart and found one of the three bolts holding the pump up in the metal dome fell off as well as a popped fuse. Replaced the fuse and tightened up all the bolts and INPA tested it again and it worked. I messed around with the ride height tuning feature of INPA and will have to zero it in a couple of mm.

Place your bets on how long until the next air suspension code/problem! I'm going to say 2 weeks.

An old buddy of mine, Jon (@thic_f30), was in town and took a bunch of pics and videos. He drove the wagon and I was in the E30. A grand time, and a lot of 3rd gear pulls, were had.

The video! E30 & Wagon content.

Update! The wagon has been running great! I've been chipping away at some minor coding things here and there.

Turned some wrenches last night at Mike's house and added the updated nitrogen charged oil accumulator. This one has a valve that locks in oil pressure when the car shuts down and on start up it immediately throws pressurized oil into the vanos units to stop the 12v Cummins Diesel sounds.

Had to run a signal wire to the DME (Pin 8 on the module 2 connector) and splice into a ground crimp. My DME was apparently one from a newer M5 with this option as I was getting a accumulator error code. No coding necessary! Thank goodness!!

Did an oil/filter change (181000 on 540i cluster) after buttoning everything up and it was clattering for a second then ran quiet as a mouse! I'm wondering if the old accumulator lost its pressure.

Replaced the cracked fuel pressure vaccum hose under the intake. Noticed both my cyclone separator return lines are totally mush and cracking so I will be replacing those next week and doing a thermostat and possible water pump as a while I'm in there approach.

The S62 is a very advanced beast and impressed that you have been able to get all these things figured out.

Dropped off the Wagon at Mike's and he has been chipping away. We're replacing the water pump, thermostat, and coolant orings/pipes under the intake manifold just to do them. Taking the family on a road trip out east and wanted to take as many variables out of the stranded on the roadside equation that I could.

I've been getting a DTML code and Mike found that the 540it pumpkins leaking donwe will be replacing that as well. SO CLOSE TO BEING PERFECT!

New cyclone separator return lines in! Got new OEM damper bolts coming due to removing the damper to get at the lower water pump bolt.

Mike's bench! Lol

Slowly blacking out the headliner. Long way to go. Black leather visors, lights and handles.

Are you going to go with all black fabric at some point to?

Jdesign

Why the black headliner?

He's going complete M5 conversion.

This in due time. Leather dash when the blower motor goes! Lol

I have some rattles in the roof and will be popping a new tailgate in probably after this winter so the headliner will be coming out. The fabric is sagging a little here and there after getting it cleaned.
