"Is the 3 Serisi 316d reliable, and what should you check?"
When buying a used BMW 3 Series 316d 2014 (F30 / F31 / F34 / F80), the most frequently mentioned issue: Electrical and Sensor Problems (Emissions System/Infotainment). Timing Chain Wear/Breakage is also commonly reported.
Engine: N47
N47D20C · 316d · Used in this car from 2009-2014
Strengths
Wide selection of versions and modifications
Economical for such power output
Watch-outs
Many problems with early diesel versions
Frequent oil leaks
Many versions have piezo injectors
Known engine issues
Timing chain driveEarly engines had low timing chain lifespan: guides wore out, chains stretched, and sharp teeth on the crankshaft sprocket accelerated the process. On updated N47TU or N47N engines, most weak points were eliminated.
Cracks in the blockThe aluminum block was initially designed without a special safety margin, and severe overheating could cause cracks between the second and third cylinders. With the update, the block was reinforced and such problems almost ceased.
Fuel systemAll engines in this series are equipped with a reliable Bosch Common Rail fuel system, but powerful versions with piezo injectors are quite demanding on fuel quality. Also, avoid driving with an empty tank, as the high-pressure pump may suck in air and start producing metal shavings.

Electrical and Sensor Problems (Emissions System/Infotainment)
Often reported
Recurring reports from F30 owners point to intermittent electrical faults: issues with EGR/DPF sensors (which can cause false alarms or interfere with regenerations), lighting system failures, and occasional infotainment/iDrive system anomalies.

Timing Chain Wear/Breakage
Often reported
The 2.0 diesel engine (N47) is known for timing chain and plastic tensioner issues. Wear or damage to the tensioner can cause the chain to stretch or jump, leading to metallic noises at idle.
Timing chain
Clogged EGR Valve and Carbon Deposits
Often reported
The EGR valve and intake manifold can become clogged with soot and carbon, especially with city driving or short trips where regeneration and complete combustion do not occur.
Exhaust Emissions
Dual Mass Flywheel and Clutch Wear (Manual Models)
Often reported
On manual transmission versions, premature wear of the dual mass flywheel and clutch.
