My original post was in another section, and I am still having this terrible problem---I think I posted in the wrong place so I'm posting here in hopes that someone can give me some thoughts, ideas, feedback as to what to do.

I have a 2009 Clubman with 67,000 miles on it. Two weeks ago my battery failed and I replaced it with one from Interstate. At the time, I DID NOT register the battery with the car (didn't know you had to). 3 days later, my aux input on the radio (which I plug my Sirius/XM receiver into) began to shut off on a 2 minute cycle, and my phone no longer pairs with the car's bluetooth.

I took it to the Dealer who told me the car battery needed to be registered and told me that I had over 30 fault codes related to low voltage. Not wanting to pay the crazy price there, I took the car immediately over to my independent garage (MINIWORX) who registered the battery to the car.

Once the car and battery were in sync I was hoping that this problem would go away, but it hasn't.

Now, no matter what I plug into my aux input (Ipod or Sirius), it shuts off every two minutes like clockwork. I have to turn the radio power off, or leave the aux input and go to radio and then come back to the aux, where after about 2 minutes, it will shut off again, and i have to repeat the process.

I had the system reset yesterday as part of a further diagnosis, but that reset didn't change anything; the problem still exists.

Before I start paying a lot of money to have the cause of this problem traced to the source, and replacing modules (which I'm told can cost 500 to 1000 for each one) is there anyone out there who has had a similar situation and found a solution?

None of this was happening prior to the replacement of the battery, but I don't want to assume that the battery replacement was the beginning of the problem---it could be coincidence.

That said, I'm told something as slight as jumping a car battery can send a surge of voltage into the system that can cause a host of related matters, some of which I am dealing with. I've read some other slightly related posts that suggest a ground wire....but this NEVER occured prior to the battery being replaced and I've had the car for 4 years so I think if that was the root, I'd have experienced that prior.

Anyone out there have any experience with this type of situation and can point me in the direction of a fix? I read in some other posts that a Ground Loop Interrupter has been a solution with some others, but I never had this problem until I replaced the battery and it's a pain to not have bluetooth or be able to use the AUX input on my car audio system.
