Hi guys, my radio interference strap is broken on my 2009 3.0 and was wondering if any of you know the part number for it ?? I am including a pic so you know what I mean. Thanks in advance....

Take a look on realoem.com

You punch in the last 7 digits of your VIN (which is the serial number of the car) and you can browse through the parts diagram.

I didn't know that's how that part is called... Thanks for teaching me something!!!

That is not broken, that is cut, as is mine. Mine is cut in precisely the same place, suggesting a post manufacture technical change.

That strap conducts around a rubber sound isolator for the muffler, right?

I do not understand the last comment. You mean does it go over a sound isolator ?? The answer is no. It just wraps around the exhaust rubber mounting. Why would they cut it ?? And then sell it as one piece ??

Just talked to the service and they said on how there is no manufacture technical change they they know about it therefore they do not cut them and it just simply needs to be replaced.

Mine is cut also, I already bought a replacement (generic ground braided wire) but hesitant to replace it. Can anybody confirm it was intentionally cut and for what reason?

Doug Huffman 07-20-2015 05:01 PM

I can evidence that it was intentionally cut by the square and even ends. If it was fatigued or corroded then the individual strands would have broken in random locations.

I was a submarine electrician and journeyman marine electrician with years of experience with grounding straps around sound mounts.

I have checked with the dealer he can't find the part number after I couldn't find it on real oem. What I did was make my own ground strap using a thick piece of copper wire, insulated.

I've looked carefully at RealOEM and have not found a muffler ground strap for the E70 diesel.

I did find the front sunroof drain pipe though!

Mine is cut in the same place, I was wondering whether it was corroded through

There is two part numbers. The dealer will tell you which one is the correct one for your car....12427570525 and 12427568573 and no the dealer says they are not purposely cut.

A hard lesson learned is, "Don't fix what ain't broke."

I still have hard time interpreting your posts. What do you exactly mean ?? Do you care to elaborate ???

bquicksilver 07-22-2015 12:23 AM

Mine was also broken. It's 12427568573

Cheers!

He means it's been cut for a reason and if it's not causing a problem don't 'fix it' or you may make a problem that wasn't there in the first place.

Thanks for translating :)
Dealer still insists that shouldn't be broken or " cut off " though :(

Have the BMW service department repair it and document the repair. Let them take responsibility for the non-problem.

The following measures have been taken in the E70 to minimize reception interference
of AM and FM stations:
• Tailgate connected to ground by the tailgate hinges with integrated ground straps
• Low-noise AM and FM antenna amplifiers with direct ground connection
• Ground connection on the left and right silencer
• Shielded Wave barrier.
The ground connection on the two silencers helps to suppress interference transmitted
from the engine compartment (ignition electronics) along the exhaust system.
The exhaust system is a wave guide and, if no ground straps are used, it carries high-fre-
quency interference to the rear end of the vehicle. At the end of the exhaust system, the
interference is radiated out and couples into the antenna structures located at the rear of
the vehicle. The ground straps on the silencers connect the interference to ground, there-
by suppressing the interference. Page 42 07b_E70 Audio Systems.pdf https://drive.google.com/folderview?...drive_web#list
