It happened on very low speed so not so many broken parts - top timing chain,sliders,4 rockers .For sake of god,was replaced 4 hydraulic adjusters and cam shaft housing box ,which is very common to crack and may be not visible straight away and can get problems in near future .She got full new set of 3 chains ,sliders,tensioners,nozzle ,fuel pump sprocket,gaskets ,crankshaft seal ,injector washers ,full engine service kit .Double mass flywheel had visual wear signs ,mowing too much front and back and leaking oil from internals,visual clutch disc wear ,so she got all new set of clutch kit with dual mass flywheel .All parts got from Frank Kean BMW in Naas road .
Car is back on road and drives perfect!

BTW it doesnt worth to get second hand engine as it would need to change chains straight away anyway and its extra expenses

Few ,not much , pictures of done work
