2009 Mini Cooper S radio just completely stopped working. Nothing

Try pulling the fuse that controls the radio power. Then let it set for a bit and reinstall it. The radio may reset its self.

Have you checked the fuses? If fuse has blown, double check the connections as sometimes vibration can cause loose wires to blow fuses.

My Mini Cooper S 2009 was hesitating and not running at full power Check engine ligth came on.. Dealer Cleaned Head gaskets UNDER WARRANTy for build ups, apparently Common in S models and 2009's
tonight completely lost compression and power while driving on Highway at nigth CAR DIED in the road TOWED to dealer awaiting update

My recommendation is to open your glove compartment and see what the owner's manual suggests what the oil change interval is.
Remember all the engines are no the same. What the garanty especify, If is a 2009 mini cooper you still have a garanty.

Have you looked into the PSP (Power Steering Pump) relay, or the cooling fan? This problem has been know to create issues and lead to a dead battery. For more information, read this forum of MINI owners, there are quite a few with your issue, and they are trying to get a recall. the 2005 MINI's also have a headlight recall.

Be thankful its under warranty. You needed four injectors usually 185.00 each plus labor.

I think the web site is called NUTS AND BOLTS .COM

Just had starter changed on Mini Cooper S '06. Tried to start the car after come back from shop and: outside and dash lights are flashing, window goes up and down but the engine wont start. Help solving this mistery.

You could always check the fuse first if that was not done. Then check the connection at the radio. Good luck
