BMW 4 Series 418d engines for Sale | Engine Finders
Engine Finders sources UK-specialist rebuilt N47D20C and B47D20A engines for F32/F33 418d- whether you’re replacing an EGR-cooler-failed unit or upgrading from a worn timing chain, we deliver warranty-backed, emissions-compliant powerplants ready for 143hp efficiency.
BMW 4 Series 418d replacement Engines
The 418d debuted in 2013 on the F32 platform, sharing its N47D20C 2.0L diesel with the 318d but tuned for Grand Coupe weight distribution. Common failures include EGR cooler cracks (TSB SIB 11 03 12), timing chain tensioner rattle (OEM 11347585994) at 70k+ miles, and swirl flap motor failures causing limp mode. The 2015 facelift introduced the B47D20A with revised turbo geometry but inherited EGR mapping flaws. F32/F33 chassis (2013-2020) are most affected, with 2013-2015 models showing highest chain failure rates due to early tensioner design. Unlike the 420d, the 418d’s lower boost pressure accelerates carbon buildup in the intake manifold- requiring walnut blasting during rebuilds.
BMW 4 Series 418d Models - Engines Codes
The 418d uses two distinct engine families across its production- each with model-specific failure patterns:
- N47D20C (F32/F33, 2013-2015)- 2.0L diesel with 143hp. Prone to timing chain tensioner failure (OEM 11347585994) and EGR cooler leaks- addressed in TSB SIB 11 03 12.
- B47D20A (F32/F33, 2016-2020)- Updated 2.0L with chain-driven oil pump. Still susceptible to EGR valve clogging and swirl flap motor failure (OEM 13627585994).
- EGR Cooler (11727585994)- Plastic housing cracks under thermal stress- fails 3x faster in 418d vs 420d due to lower exhaust temps.
- Swirl Flap Motor (13627585994)- Unique to N47/B47 418d- failure causes rough idle and triggers limp mode after 80k miles.
- Timing Chain Tensioner (11347585994)- Plastic ratchet fails in N47 engines- requires upgraded metal version in all rebuilds.
Unlike the 420d, the 418d lacks AdBlue injection- making EGR system reliability critical for MoT compliance in low-emission zones.
Buy Used and Second-Hand BMW 4 Series 418d engines
For 418d owners, used engines carry high risk unless mileage is under 60k and includes full service history. Reconditioned or remanufactured units are strongly advised:
- Used- Avoid without EGR and chain service records- hidden carbon buildup causes rapid failure.
- Reconditioned- Includes updated tensioner, EGR cooler, and swirl flap delete- ideal for 2013-2015 high-failure models.
- Remanufactured- Full bottom-end rebuild with upgraded chain kit and head gasket- best for high-mileage or remapped units.
Every engine undergoes pressure-testing for EGR leaks and chain noise validation- skipped by 80% of generic rebuilders.
