Same here. So disappointed on BMW
The same just happened to me. Im glad this thread is here so BMW service cant act like this only happened to me. I have a babied 47k miles 2008 bmw m3 and this just happened. they are asking me to pay 26K +++ for a new engine. I will be showing this to my lawyer and work on getting them to cover it. I complained of engine noise so many times throughout the 4 years of warranty and they always came back with no problems with the car. i even had them do a final service before the warranty and yet again no one picked up anything supposedly. Its messed up between myself and my family we have owned over a dozen bmw's and they better make it right.
I'll post it with a video tomorrow and ad it to here for others who get told they need to pay 26k to get their car back after spending a lot on this car and taking care of it like a baby for the last 4 years. No engine mods, never raced, only put 4k miles in the last 12 months.
As soon as warranty expires. 2k miles later then engine blows for no reason.
