When buying a used BMW 3 Series 328i 2013 (F30 / F31 / F34 / F80), the most frequently mentioned issue is: Oil consumption and leaks (including plastic oil pan). Also, VANOS/VVT errors and 'drivetrain malfunction' warnings are commonly reported.
Engine: N20
N20B20A · 328i · Used in this car from 2012-2016
Strengths
Relatively low fuel consumption
Good potential for chip tuning
Watch-outs
Timing chain has low service life
Frequent leaks from under valve cover
Plastic pipes have short lifespan
Known engine issues
Timing chainThe most famous weak point of this engine is the modest service life of the timing chain, sometimes it lasts less than 80,000 km. Note that units after 2015 have a longer service life.
Oil pump chainAnother widespread problem of early engines was the breakage of the oil pump chain with fatal consequences. A new thicker chain appeared in September 2012.
Piston destructionN20B20A engines with compression ratio 10.0 are easily tuned and run without much trouble, but N20B20B engines with compression ratio 11.0 suffer from detonation after chip tuning.
Listed from most frequently reported, each with its source.
Oil consumption and leaks (including plastic oil pan)
Often reported
Higher than normal oil consumption and localized leaks are widely reported. Some users mention frequent need to add oil and cracks or leaks in plastic components (oil pan/engine lower cover) causing the lower engine cover to be soaked in oil.
Engine Internal
VANOS/VVT errors and 'drivetrain malfunction' warnings
Often reported
Documented cases of VANOS/VVT fault codes or 'drivetrain malfunction' messages: intermittent symptoms such as torque loss, check engine light, or erratic behavior after long trips.
Engine Internal
Faulty timing chain guide
Often reported
Timing chain guides in the 2.0 N20 engine are prone to wear or breakage, causing chain slack, noise, and potential engine damage.
Timing chain
Rattling/clicking noise and wastegate failure (turbo)
Often reported
Many users report a rattling or whistling sound from the turbocharger wastegate actuator. The mechanism wears or sticks, causing loss of boost pressure, 'drivetrain malfunction' warning light, or reduced performance.
