Second-generation 2 Series Coupé built on the CLAR platform shared with the G20 3 Series and G22 4 Series. Production started September 2021 in BMW's San Luis Potosí plant in Mexico. The 220d uses the proven B47 four-cylinder turbodiesel paired with a 48V mild hybrid system and ZF 8HP automatic. Many cars are still under factory warranty - verify coverage and service history carefully.· more· less
B47 engine is proven and well-supportedZF 8HP gearbox is highly regarded
Buy if: You want a refined rear-wheel-drive coupé with strong diesel torque and have verified both the EGR cooler and starter motor recalls have been completed.
Avoid if: You only do short urban trips (DPF and EGR will suffer) or want to avoid the complexity of mild hybrid plus emissions hardware on an out-of-warranty car.
Worldwide recall on diesel EGR coolers - coolant leak into intake can cause smouldering and rare fires · more· less
BMW issued a global recall affecting around 800,000 diesel vehicles including the G42 220d. The EGR cooler can develop internal cracks allowing coolant (glycol) to leak into the intake manifold. When mixed with diesel soot at high temperature, the deposit can smoulder and in rare cases cause an engine bay fire. BMW developed a redesigned cooler from a different supplier in 2022. Repair is free under recall - dealers replace the EGR cooler and inspect the intake manifold, replacing it if needed. CRITICAL: verify recall completion using VIN before purchase. Some forum reports suggest the replacement cooler can fail again after a few years, so post-recall failure is still possible (€2,000-4,000 if out of warranty).
Starter motor overheating (recall)
€0 - 1,5002 of 7
Affects 2022-2023 G42 cars with starter relays produced July 2020-July 2022 · more· less
BMW launched a global VIN-specific recall covering roughly 575,000 vehicles including G42 2 Series. High start-cycle wear on the starter's magnetic switch can cause hard or no-start conditions and, in rare cases, a short circuit and localised overheating that could lead to fire while driving. Interim guidance from BMW: do not leave the car running unattended. Remedy is starter replacement (and sometimes battery), free under recall. Verify with VIN whether your car is affected and whether the work has been completed. Out-of-warranty replacement cost is approximately €800-1,500 if the recall does not apply or has lapsed.
B47 timing chain wear
€1,800 - 3,5003 of 7
Less prone than the older N47 but chain stretch is still possible with neglected oil changes · more· less
The B47 was designed to fix the notorious N47 timing chain issue by relocating the chain to the front of the engine. However, the chain itself uses similar single-row design and can still stretch over time, especially with extended oil-change intervals or short urban trips. Symptoms include rattle on cold start lasting more than a couple of seconds. Most G42 cars are too low-mileage for this to manifest yet, but specialists recommend 7,500 km oil intervals with full-synthetic oil to prolong chain life. A failed chain on the B47 typically requires the engine to come out for access (chain at the rear), pushing repair costs to €1,800-3,500 at independent BMW specialists.
DPF and AdBlue/NOx sensor faults
€300 - 2,0004 of 7
Short trips clog the DPF; AdBlue NOx sensors fail and trigger limp mode · more· less
Modern Euro 6d diesels have a DPF, SCR catalyst, AdBlue injection and multiple NOx sensors. NOx sensors are a common failure point on B47 cars - typical fault codes P2200, P204F, P20E8. A single NOx sensor is around €300-500 fitted at a specialist. A clogged DPF requires either a forced regeneration (€150-300) or replacement (€1,500-2,500). Avoid cars driven only on short urban trips - look for a service history that includes regular highway use. Check the dashboard for any AdBlue countdown warning before purchase.
iDrive 8 software glitches
€0 - 8005 of 7
Random reboots, black screens, CarPlay drop-outs and Bluetooth pairing loss · more· less
iDrive 8 introduced with the G42 has been criticised for software bugs - random screen reboots while driving, the central display going black, paired Bluetooth devices being forgotten after the car has been off, and Apple CarPlay/Android Auto GPS position drift. BMW issues regular over-the-air updates and dealer software flashes; most issues are software-only and resolved through updates. Verify the car is on the latest software version. If a hardware swap is required (rare), the head unit is several hundred euros plus labour, but most cars are still in warranty.
ZF 8HP mechatronics issues
€1,500 - 3,5006 of 7
Generally robust but BMW's lifetime fluid claim is unrealistic for long ownership · more· less
The ZF 8HP fitted to the G42 is widely regarded as one of the best automatics in production. Failures are rare in the early years but the mechatronics unit can develop issues with prolonged use - solenoids, valve body, and the connector sleeve are wear points. BMW labels the fluid as 'lifetime' but virtually every independent specialist recommends a fluid and filter change every 60,000-80,000 km to prevent premature failure. A mechatronics rebuild runs €1,500-2,500 at a specialist; full replacement can reach €3,500. Most G42 cars are too new to show issues yet, but a budget for fluid service should be planned.
48V mild hybrid system faults
€500 - 3,0007 of 7
Belt-driven starter-generator can fail; software updates often resolve early issues · more· less
The G42 220d has a 48V mild hybrid system with a belt starter-generator (BSG) and small lithium battery. Reported failures include drivetrain warnings, engine cut-out in Comfort/Eco modes, and rare BSG replacement. Many issues are software-related and fixed through dealer updates rather than hardware replacement. A new BSG fitted at BMW is approximately €2,500-3,000 but is unusual at this age. Most early problems are resolved through software updates that should already be applied to current cars.
Modern diesel with two active recalls - verify both before purchase
The G42 220d is a relatively new car so long-term reliability data is still emerging. The proven B47 engine and ZF 8HP gearbox give a solid foundation, but two active safety recalls (EGR cooler and starter motor) directly affect this model and must be verified as completed via VIN. Diesel-specific items (DPF, NOx sensors, AdBlue) and iDrive 8 software glitches are the most common owner complaints reported on forums.
Service history
Complete BMW dealer or specialist records essential. Verify oil change frequency - prefer 7,500-15,000 km intervals over BMW's longer recommended schedule.
Tires
Run-flat tires fitted as standard. Check tread depth, age, and uneven wear (rear tires wear faster on RWD).
Cold start
Start engine completely cold. Listen for any rattle in the first 10 seconds (potential timing chain wear).
Test drive
Minimum 30 minutes including motorway speeds. Check that the DPF regenerates without stalling.
Specific for this vehicle
Verify EGR cooler recall completed via VIN
This is the single most important check. Contact a BMW dealer with the VIN to confirm the EGR cooler recall has been carried out. Without confirmation, assume it has not.
Verify starter motor recall completed via VIN
Cars built between July 2020 and July 2022 may have an affected starter relay. Confirm with VIN that the recall work has been done if applicable.
Check iDrive 8 software version and behaviour
On a 30-minute drive, watch for random reboots, black screen, or Bluetooth/CarPlay drop-outs. Most issues are fixed by latest dealer software update.
+ 3 more checksShow less
Verify no AdBlue countdown or DPF warning
Check dashboard for any AdBlue distance countdown or DPF warning. A countdown means a NOx/SCR fault has been logged.
Listen for cold start rattle
On a fully cold engine, listen for any chain-like rattle for more than 1-2 seconds. Brief rattle is normal; prolonged is a warning sign on B47 engines.
Check transmission fluid history
ZF 8HP benefits from fluid changes every 60-80,000 km. Ask whether this has been done; many BMW dealers omit it.
Contact a BMW dealer with the VIN to verify all recalls have been completed. The EGR cooler and starter motor recalls are both fire-risk recalls and should never be left open.
Warranty Status
Factory warranty (2 years EU + 1 year Plus until 2024)May still apply on cars under 3 years old
Rust perforation warranty (12 years)Active on all G42 cars
Recall coverage (EGR cooler, starter motor)Covered free of charge regardless of warranty status
Extended warranty availabilityBMW Premium Selection or third-party available
The G42 launched in late 2021, so many cars are still inside the original 2-year EU factory warranty (or 3 years with BMW Plus where bought). Always check the warranty status of the specific car. The two open safety recalls are repaired free of charge regardless of warranty status.
