BMW N13 engine reliability, problems and repair
New gen BMW 4-cylinder engines called N13 (Prince) were developed in collaboration with French PSA Group. BMW N13 motor was produced in 2011 and replaced all previous naturally aspirated 4-cylinder engines such as N43B16, N43B20, N45B16, N45B20S, N46B18 and N46B20.
N13 cylinder block was made of aluminum combined with dry iron-cast sleeves. It also had forged crankshaft with 8 counterweights, connecting rods 138.5 mm long and Mahle pistons 77 mm in diameter.
It was equipped by new cylinder head and variable valve lift system Valvetronic III as well as BMW N55 and N20. At the same time Double-VANOS variable valve timing on the two camshafts was used in addition to direct fuel injection.
Twin-scroll Garrett MGT1549ZDL turbocharger in BMW N13 operated under 10 psi (0.7 bar) boost.
Engine was equipped by Bosch MEVD17.2.4 control unit.
This engine was used in BMW 14i, 16i, 18i and 20i models.
