Update:
Took the car in and the SA said lets hear it out. The ticking noise was there but not very clear. He had the shop foreman hear it and he did agree that there was a noise. They were hesitant to give me a loaner so asked me to wait a while they look at it. If it turns out to be nothing they said they will give the car back to me in an hour or so. I thought to myself they better not do that.
Anyways while doing the paperwork I did bring it up to the SA about stuff on the internet and the rod bearing failures on the M3's and asked him if they have had any E9x M3's with a BF. Of course he rolled his eyes like what fucking bearing failures are you talking about and said no. He said don't read a lot into the internet and the forums, there's a lot of BS out there
Finally after waiting for close to two hours he says they were not able to determine the cause and will need extra time to diagnose and gave me a loaner.
I will know on Monday what is going on. Till then fingers crossed..
