Cool Ignition Wire Harness Voltages/2000 528i

Hello all,
I own a 2000 528i, and the Ignition Wire Harness was recently cut in an attempted car theft. I believe this is the x33 cable. It has 6 wires running to it, and all 6 were cut. The wires are as follows:

Pin 2-Terminal 30-purple
Pin 3-Terminal 30-green
Pin 5-E voltage-red
Pin 6-E voltage supply-red
Pin 7-E voltage-red
Pin 8 -Signal DME-black

I soldered the wires back and attempted to start but I am not getting an power to dash, or start. I checked for voltages, and had about 6 to 7 volts across pins 2 and 3 and one of the reds(not sure which one.

I am not sure what the voltages should be at each key position, or prior to the key being placed in the ignition. Could someone please help me out as I am really needing to get my vehicle running.

Thanks in advance

GOod luck

Ignition Harness 2000 528i

Hi, Thanks for the quick reply.

I did check the ones in the glove box and the truck, but not sure how to get to the ones below the passenger seat. Would I have to move the seat to get to these fuses? I believe the red wire fuses are located there.

Yes, remove the seat. Also there's a stack of fuses under the right hvac filter housing.

See the attached schematic for your car
Nothing for pin 9?

6 or 7 volts from pins 2, 3 and a red is a bit unclear as to which to which. It could be a case of B+ from a red to fuses on pins 1 &/or 2 has just enough conduction through the voltmeter (which has very high resistance) that the voltage drop of the small current is shared between the voltmeter and the devices on the fuses. Or is the car battery is badly discharged?

A836 is the EWS module according to WDS, associated with but not the DME itself

You'll have to pull a fuse to identify which red 4 mm2 is which. Both F111 & F114 should be at B+ all the time, i.e. unswitched. F114 is easiest to get at - see the locator picture. EDIT: I should have mentioned - over battery behind a white plastic cover, mounted on the wheel well.

X10202 provides B+ to glovebox fuses F37 to F45 when switched.
X10176 has locator only, no schematic, but it connects to the glovebox fuse block too

Pin 9
F34 feeds the steering wheel heater - if fitted
F35 feeds rear compartment blower - if fitted

I doubt there is damage from shorts. Every wire in or out of the ignition switch is at B+ voltage at some times depending of key position. None of the wires are grounds.

Are you OK reading schematics? Post back if you need more help on a testing strategy.

EDIT2: Oops, not the schematic I intended. I've added the "with IHKA" version which includes F35

Cool Ignition harness/200 528i

Thanks RDI for the information. It will come in handy when I work on it this weekend. And, yes I am very good in reading schematic. Was in the electronics industry for years. Once I come up with a conclusion or a fix, I will post.
