I bought a CPO 2007 328i just 2 months ago with a Platinum warranty package. For the last 2 days it's been ticking. I was horrified to find out so many people affected by this.
I took my car to my dealer yesterday and got a 2013 5 series as a loaner. Driving the loaner car pacified my frustration with the ticking of my car for a while.
Expecting a call from the dealer anytime today. I hope they don't give me the BS that they couldn't hear the tick coz I have recorded on my phone, thanks to the info I found in this forum. Will keep you guys posted.
