conti cars max can keep 5 years after that better sell fast fast

otherwise if u got extra cc just to take care of it, well...

Ya BMW and their leaks memang famous. If your BMW dont leak, then it's not a BMW. Coolant and oil leak specifically. Even the B48 TU also same problem adui

Combination of plastic parts and high temperature engine at 110c....some mechanic say not recommended to tukar the parts to aluminum cause it retains heat and make things more worst.

So yes in short prepare 10-20k a year for the repair/maintenance fees.

But actually leak coolant or oil is easy to detect and if change/repair early then no problem one. Usually it's the few most common parts like valve cover gasket, thermostats, coolant pipes etc. Most problematic is some hidden valve/pipe/bush/parts that cracks and you can't see it easily...
