the positive cable to the battery....
Any idea if I can get a replacement? Also the positive cable will not fully tighten against the battery post, do I need a full cable?
wrong size battery?
Which bolt did you break?
No bat is correct...just overdid it...
OK CNN so you see the nut which you tighten in the main red cable where it connects to the battery? The nut that tightens a vertical bolt that has a sadle on the bottom of it...the saddle pulls the clamp tight...that bolt/saddle thing, I broke the bolt only from the saddle...
Did you strip the thread or did you break (snap) the bolt off?
The BMW battery bolt has "hooks" at the bottom. When tightening the nut, the "hooks" tighten both sides of the battery terminal to establish a tight connection. See pic.
The goofy BMW engineers don't offer the bolt as a separate item!
And you don't want to know the cost of the entire red cable assembly, it is something like $300 plus labor (very labor-intensive to replace the red cable!!!). This is because the red cable has an explosive charge built into it. In the event of an accident, the explosive charge detonates and electrical cable is severed to prevent fire, electrical sparks etc. This is why this red cable is very expensive.
Your options are:
1. Ebay (I doubt you can find the battery bolt)
2. Junkyard
3. Try VW part:
www.1stVWparts.com
Positive battery cable T-bolt:
PN: 6X0-915-138
$6.00
You can see the VW design uses the same setup, for $6.00, you cannot lose much:

Report back what your solution is, so others may benefit from!
PS: If I remember correctly, the torque is around 5 Nm (basically tighten until it stops and give it a slight tug!).

Many many thanks, this forum rocks...
Thanks CNN
Pat
From what I gather, the VW part comes with the bolt only (no nut). I may be wrong.
Anyway, don't throw away your broken nut/bolt yet!!!
