O, that seems to work. Cranks over but battery seems low, it doesn't start. Im going to try to jump it.

I jumped it but still only cranks slow and doesn't start. It showed 13.5v before i tried then after couple tries the voltage goes down to low 11

That's a Good sign and definitely its a ground issue.I attached the pictures showing good points to connect the cable on engine and chassis.On chassis,there is a lead nut that's specifically for the ground hookup.You can use both red and black cables together to make sure you are feeding good ground to the engine.

Use both wires as shown in the pic to supply good ground to the engine.Using both might help it to turn faster.In the last picture,i removed the red wire just to have a proper view of the point.But you can setup the wires as shown in first 2 pictures.

Sweet, that worked. I used those locations with one wire but connecting both sides made it start.
Appreciate the help. Now, i need to find this chassis ground wire to make sure it's not falling apart.

Glad it worked for you.I think this ground problem was first found by one user here or at bimmerfest.

Glad it is sorted.

I tried to start again and it wouldn't, i think my battery is in need of replacing as well but tomorrow i will look at the ground wire and see if it needs replacing. Thanks for the advice.

Did you mean that after removing jumper wire,engine would not start?

Ozer · #18 10-31-2015, 05:48 PM

Yeah i took it around the block and let it idle for 5 mins, turned it off and tried to start again and it wouldn't start. Then i tried to jump the ground again and it wouldn't turn over. I jumped it from another battery, with the group bypass on and it still wouldn't crank over. I will try to replace the wire tomorrow, no time left today to keep working on it.

Put your battery on charge overnight while you are sorting the engine ground strap before giving up on it

Can i charge it from the engine bay or have to charge the actual battery from the trunk?
