There was one thing left that I hadn’t tested for in my quest to sort the idle issue, and that was the fuel pressure.
After 300,000km, the old suspension was no doubt a little on the tired side. An easy fix is to fit a set of adjustable suspension. So, that’s what I did.
Another part of trying to sort the idle is to replace the idle control valve, which has been a bit suspect from the beginning.
In my quest to smooth out my idle issue, I wanted to remove and check the DME and VNC units.
Ah yes, that time again. It’s not my M3 if it doesn’t involve rebuilding the Vanos at some point.
Well, the time has come. I’m keeping the BMW for the foreseeable future, so the only logical next step was to drop some dead weight, and pull out the subs.
Its been a while, for two main reasons, but I’m still here, and for now, so is the BMW.
Well this is a familiar job, the old brake light switch failure.
One last thing I needed to fix, so that the car would reliably start, was the ignition barrel. Sometimes it would free spin, and wouldn’t start the car.
