I had an 07 e93 for about a year .. even though it had a 2 year BMW warranty I ditched it after less than 1.
The engines are woeful in them...
Mine kept throwing misfires and I had 8 injectors and coils replaced...
Timing chain replaced
Gearbox oil leak
Failed headlight
Consuming a liter of oil every 2k miles.. and very gutless - diagnosed as valve stem oil seals.
The n52 engine (I think) is well know as troublesome...
But maybe I had a bad one...
