Hey guys I have a huge problem, maybe someone can give me some advise or any thoughts are much appreciated.
I have a 2011 535xdrive, never had any issues with the engine, was changing the oil every 5k miles, now I have 93k miles on it. On Friday went to replace the oil sensor and oil cooler gasket. Everything was fine, but next day out of the blue my engine died on me while driving about 50 mph. I heard a clicking noise which was the transmission, it went from D to N by itself and the RPM were down. I pressed the gas pedal a few times and nothing, realized that the engine was off, so I pulled on the side of the road. Put the transmission to P and tried to start the engine. It made a pretty awful noise but didn’t start, after trying to hit Start button again it just made a click and that’s it. Not sure what happened, at this point I’m left without a car and huge headache. Looks like I’ll have to replace the engine. Did anyone have a similar situation? Can anybody suggest a solution? Any thoughts? Every opinion counts.
thanks a ton

Yes, I towed it back to the same garage where they replaced the cooler gasket and oil sensor. They got back to me today saying that they couldn’t find anything wrong, and everything looked fine and they’re still working to find out what might have caused it. As far as I understood they didn’t get the chance to completely disassemble the engine and look inside, looks like they will do it tomorrow

Got an update from the mechanic, so they say that Cyl number 6 seized, can’t figure out why... everything looks ok. I asked if we can just replace that part, he’s reply was that “The crankshaft is bad it looks like the engine replacement is more logical, used crank is 1000$ rod is 200$ and set of gaskets and machine shop is around 1500$. So it’s very close to engine price” he assumes that a replacement engine will be around $3,000. Any thoughts on this? Anyone ? I live in NY, can anybody suggest where I can get an engine for about that money?

this mechanic is actually a friend of mine, I don’t think he would try to rip me off. He did some research as well and said that many people faced same situations. The car just died on them, no lights no warning signs, it just stopped working:( I asked if it pays to just replace the parts (which are also close to $3000) he said that he wouldn’t recommend that. What if after the repairs the engine would do the same, I’d be in really bad situation, too much $$ involved... I’m so upset because this car didn’t give me any problems, and now BOOM.... very sad

got you:) I’ll try to ask around if there’s anyone who would like to stop by and look at it, because at this point the engine is out and can’t take the car anywhere
