Engine: N47
N47D20C · 2.0d · Used in this car from 2008-2010
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.

Intermittent warning lights due to sensor or wiring problems
Often reported
Italian forums report frequent intermittent check engine lights caused by engine-related sensors (pressure, catalytic converter, EGR) or wiring/electronic issues.
Electrical
Timing chain wear and breakage
Often reported
The 2.0 177 HP diesel engine (N47) is known for premature wear of the timing chain and its guides/tensioner. This can cause metallic noises from the rear of the engine and risk of breakage, leading to severe engine damage.
Timing chain
EGR valve and DPF clogging
Often reported
Frequent carbon buildup in the EGR valve and intake passages, as well as DPF and sensor issues, are reported.
Exhaust Emissions
Turbo / wastegate actuator failures
Often reported
Some 2.0d examples report turbo or wastegate actuator replacement or failure; power loss, whistling noise, or increased smoke may occur.
