2001 x5 4.4 starts then dies.....HELP!!!!

Hey guys Im still down . I know a guy with DIS (bmw software) but he wasnt sure if there was a step in the software that Im missing that makes the pedal talk to the throttle. Right now I have the ecudoctors DME, perfect wires and harneses from pedal to DME, DME to throttle body and a new pedal and throttle. Still showing to high of voltage to throttle codes.

Does DIS have a step in it Im missing. I get the initial open/shut on turn of key of the throttle body but no 10 or 30 second initialization process w/ the key seems to do anything.

I still have me old DME but its useless now, I have the new DME synced to my EWS now.

Saw this on the net regard P0123

OBD II Code P0123

Could you have a break in the harness somewhere?

[blakey2000]

Nope every wire tests out 100% continuity and ohms out at. 3. Which is good

But wouldn't the old DME still be synced to the EWS?

[blakey2000]

no, ews is now synced to new DME

[blakey2000]

well I had it towed off to someone else. Over trying to figure it out

Maybe this will help in the future.
This is what has happened. The DME internal circuit 15 is the 5 volt supply for some sensors. It is the supply for the throttle actuator. This voltage is now battery voltage causing the codes for high voltage as it returns to the DME over the max of 5 volts. Have seen this on a few 4.4l w/ DME 7.2's.

Looks like George goofed on this DME repair or something is shorting this circuit.

[blakey2000]

Thats what im hoping. George just sent out another dme. I hope it works!

[blakey2000]

What have u seen cause the short?
