Reliability snapshot
The F32/F33/F36 4 Series is the coupe, convertible, and Gran Coupe derivative of the F30 3 Series, so its common items mirror that car: the early N20 four-cylinder timing chain, the oil-filter-housing gasket, and cooling components. The N55 and later B58 six-cylinders are strong. It is a dependable car when the early N20 chain concern is checked and routine cooling and gasket maintenance are kept up.
