Exactly what I'm referring too. Most of the time disconnecting the battery for 30 minutes clears the code.

why would it reactivate????? I had it disconnected but it seems to get the disable code again when I try to start the car.........

Try BAV's method. I would say their is a capacitor or small battery somewhere that stores some charge to prevent my method. I had to do the 30 minute method with an e36 vert some time ago.

[Trptguy]

yeah i will try it

[Trptguy]

ok key is in position 1 and the obc lights came on, now to wait for 15min and see if this works

[Trptguy]

dammit!!!!! same shit happened. I am now wondering if the main relay is also fucked. I already tried jumpering it but i will try again tomorrow.

[Trptguy]

so when i tried to jumper the main relay today and follow the bav auto routine I had a buzzing happening but that was it....

wish i was jlevie and could figure this shit out

[Trptguy]

well my brain is completley fired I can not figure this out.

Anyone know how you jumper or bypass the OBC relay?

You are a fool if you haven't cleaned both sides of those cables. I can see from your pic they are a problem.

[Trptguy]

already cleaned and put back together, still not working. waiting on a new main relay and have left the obc relay unplugged for 24hrs

I wasn't the battery lines. Did you you look on line for the Electrical Troubleshooting Manual?

Who's nearby you? they can't loan you a Main relay from a known running car? I know I have a few but won't be out your way this week.
