"Is the 1 Serisi 116d reliable, and what should you check?"
When buying a used BMW 1 Series 116d 2010 (E81/E87/E82/E88 facelift), the most frequently mentioned issue is premature timing chain wear/breakage. Also, EGR/DPF clogging and emission problems are commonly reported.
Engine: N47
N47D20C · 116d · 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.
Listed from most frequently reported, each with its source.
Premature timing chain wear/breakage
Often reported
The N47 diesel engine is known for premature timing chain wear and stretching, with risk of breakage. It often manifests as a rattling noise at idle or low revs, and chain breakage can cause severe engine damage.

EGR/DPF clogging and emission problems
Often reported
Especially in city-driven diesel engines, EGR valve and diesel particulate filter (DPF) clogging can occur. Symptoms include frequent or incomplete DPF regenerations, intermittent engine warning lights, performance loss, and varying fuel consumption.
Exhaust Emissions
Turbocharger failure
Often reported
Some N47 engines report turbocharger (or turbo actuator) failure or malfunction, which can cause power loss, smoke, or abnormal noises.
