I then got the radiator, new temperature switches, all new hoses, and a new thermostat installed:
I then refilled the system with the good BMW coolant and went to start the car. Cranked and cranked, but wouldn't turn over. Bummed. I figured maybe my battery had been drained a bit and didn't have enough juice to get it going so I decided to charge it up. While waiting I started poking around, and realized that I had clipped my crank position sensor in the wrong groove when I did the timing belt. This effectively had the sensor about 1" from the harmonic balancer rather than right up against it, as it should be. I figured that HAD to be it. So I put the fully charged battery back in, crank crank crank and no start. Now I was getting a bit nervous. I decided to check the C104 plug by the DME because I couldn't remember if I plugged it back in or not, I had. While I was in there I played around with the big DME plug and it fell off, turns out I hadn't clipped it all the way in. I pushed it on all the way, turned the key...
SUCCESS!
The car idled better than it ever has after warming up. I then bled the coolant with the heater on full blast and the front of the car raised up a bit. After all the air was out, it was time to take it for a spin. It ran PERFECTLY, I was giggling like school girl the whole time shifting through the gears, everything was nice and smooth and the car was a BLAST to drive. After about 10-20 miles or so I felt comfortable that everything was working properly so I decided to get my Conforti chip installed:
Remove the 4 phillips head screws on the back plate of the DME, followed by 2 phillips and 2 flat head screws that hold the circuit board in place. Flip the circuit board out:
The chip you'll be replacing is the one with the white paper label in the lower left corner.
