Universal Fiber Optic Loop Bypass Loop Adapter Compatible with BMW, Mercedes & More

I would give 6 stars if I could. I was having no SOS and No warning tone errors in my e92 m3 so I ordered this loop to try to diagnose the issue. When the loop arrives it comes with a card offering assistance via Amazon messages or Instagram DM. I reached out to Mods and Projects (the seller) and they were incredibly helpful in diagnosing the issue. They offered step by step guidance and together we were able to find the bad module. When you order from this seller you are getting more than just the part, you are also getting the support and help in diagnosis. I’ve saved hundreds of dollars in diagnosis time by sorting this out with the sellers help vs going to a shop.

Seriously, fixed this common problem. Took 10 mins. And since it's a common problem I didn't bother doing detailed troubleshooting, just tried this cable and it fixed it.For reference, in the 2008 e92 m3 the defective satelite radio module is not labeled as such. Its the one on the left hand (drivers) side in the back of the trunk. There is another module on the far left hand "shelf" that says "tuner" and is less accessible, i thought that might be the problem but it wasn't (at least for me)

Product works but didn't solve my particular issue.The seller diagnosed it after i contacted him, gave me a contact that specializes in my issue, and even encouraged me to return the part!I would buy from them again!

Worked immediately. 3min install after clearing out the trunk. Highly recommend!

The item itself worked great, however what blew me away was the customer service I received. Although the item worked, it didn’t solve my error code, so I contested the seller and he helped me troubleshoot and resolve the issue. It’s rare to find customer service like that.

Product was what was described in ad. Customer service was excellent. A pleasure to do business with.

Little more expensive,but requires no modifications.

The only one that fits. I bought one of the others that comes with a male and female connector, but the connector did not fit my BMW (e64). This loop fit perfectly.I was able to determine that the XM module was not functioning and was the “burned out bulb in the line of Christmas tree lights”. Because of the faulty XM module, the amplifier was not working. There were no sounds from anything, not even the back up sensor. I disconnected the fiber optic cable from the XM module and plugged in this loop, thus bypassing the XM module and everything else came back to life. I will keep the loop in place until I replace the XM tuner.
