And I think I have it figured out, though I'm at work at the moment, so I'll fix it when I get home. I have the Resler interface sitting in the cupholder, because I couldn't figure out how to connect it. I completely overlooked the ibus plug on the harness...

Replaced the rear wing that was pulled off in the carwash... new one seemed to be loose as well, so drilled an extra hole and put a BMW splitnut in it to make it authentic

Also, the rear door handle with the licence plate lights in it was missing screws, apparently the MOT mechanic did a quick fix by adding a wire to the lights but drilled holes i the back... so water runs into the lights, doh! I got some new square grommets for the screws, new screws and put some liquid rubber in the holes... now to let dry and replace the rotted out bulbs....

No DSP is pretty much drop in. Just screw in the brackets, and maybe a little tweaking to the existing plastic.

Really easy, unless you want to run cameras.

I was getting secondary air injection codes (banks 1 and 2) so I took the pump out and tested it with a 12v battery. It fired right up and seemed to work fine. Would this indicate that the valve in the exhaust manifold is not opening, either because of a bad valve or a bad vacuum solenoid?

There are only three parts I think, so if it isn’t the pump, then it’s got to be the solenoid or the valve. All are answerable to the DME and can set a code. I would think you could test the remaining two fairly easily.

There is a slight chance you could have a short in the harness too I guess.

Gotcha, thanks for the reply. I was mostly wondering if I was missing any other parts of the system or not. I will test the valve next. Thanks!

Did yet another oil change yesterday. Got motivated to pull the plate and do the front diff as well.

Oil consumption seems to have gone way down in the course of my ownership. It was concerningly bad at first (nearly 100% consumption in 3,000 miles, which is outside of even BMW's "guidelines"), but it seems that a course of rapid interval changes with decent synthetic, as well as a couple of LiquiMoly Pro Line Engine flush treatments have helped a LOT. At this point, I think that oil loss is at least as much due to the pan gasket as anything else. ~2 quarts in 5,000 miles is not awesome, but it's certainly tolerable.

not that I have yet, but about to burn it to the ground.
getting codes that dont point to anything and replacing the ICV didnt fix it.
anyone seen these before/together
D3 Idle speed Control Valve mechanical fault
55C4 No message from DSC
5F1D DSC Engine management interface
91 EGS CAN torque reduction

I do have a separate thread for it but since a lot of people read this one

Reply to ongoing post:
My start would be 55C4. No message from DSC. A wheel speed sensor is acting up intermediately. Or steering angle sensor? The last two probably relate to 55C4.

As for D3, I would suspect the MAF sensor. Clear the codes and run without the MAF connected. How long does it take for a code set? Drive it reasonably to the same amount of time.

Are you playing in any USTA leagues? Sandbagging is an art form. Not too many people can pull it off while looking genuinely innocent.
