The entry-level 2 Series coupe with BMW's B38 three-cylinder turbo, shared with the Mini Cooper and 118i. It covers the 2015-2020 three-cylinder cars; from 2020 BMW switched the 218i to a 2.0-litre B48 four-cylinder with the same 136 hp. The F22 platform is one of BMW's more reliable modern designs, offering rear-wheel drive in a compact, engaging package. The B38 engine is fundamentally sound, but timing chain tensioner wear, turbo wastegate rattle, and cooling system components require attention as mileage accumulates.· more· less
Simple, proven drivetrain layoutLow fuel consumption for a BMW coupe
Buy if: You want an affordable rear-wheel-drive BMW coupe with low running costs and can find one with complete service history and shorter oil change intervals.
Avoid if: You need strong motorway performance (136 hp feels modest in a coupe) or want to avoid the monitoring that direct-injection three-cylinder turbos require.

Tensioner loses pressure over time, causing cold-start rattle and risk of chain skip · more· less
The B38 uses a timing chain rather than a belt, but the tensioner is a known weak point. As the tensioner wears, it loses hydraulic pressure overnight, allowing the chain to slacken. This produces a distinctive rattling noise for several seconds on cold start. Typically becomes noticeable between 80,000 and 130,000 km. If ignored, the chain can stretch enough to skip a tooth, causing valve-to-piston contact and catastrophic engine damage. Short oil change intervals (10,000 km or less with quality synthetic oil) significantly reduce the risk. BMW has issued updated tensioner parts. Replacement involves the chain, guides, tensioner, and sprockets. Independent shops typically charge €1,200-1,500, while BMW dealers can reach €2,000-2,500.
Turbo wastegate rattle
up to €2,0002 of 6
Wastegate actuator develops play, causing audible rattling at low RPM · more· less
This is one of the most common complaints about the B38 engine across all models that use it, including the Mini Cooper. The electronic wastegate actuator develops mechanical play, producing a noticeable rattle during low-RPM driving, particularly in Comfort and Eco Pro modes. BMW has this tracked in their PUMA system as a known issue, though some dealers still dismiss it as normal operation. The rattle itself does not cause immediate mechanical damage, but a worn wastegate can eventually affect boost control. If only the actuator needs replacing, specialist shops charge around €400-600. If the entire turbocharger assembly needs replacement, costs rise to €1,500-2,000.
Coolant pump and thermostat housing failure
up to €1,2003 of 6
Belt-driven coolant pump or plastic thermostat housing fails, causing overheating risk · more· less
The B38 drives its main coolant pump mechanically from the belt and pairs it with a plastic thermostat housing. Both are known wear items on BMW's modular engine family. The thermostat housing can crack or warp from thermal cycling, and the pump can start seeping or seize. Typical failure window is 80,000-130,000 km. Symptoms include coolant warning lights, engine running hot, or poor cabin heating. Both components are often replaced together since labor overlaps. Parts cost approximately €300-500, with labor adding another €300-700 depending on whether an independent shop or BMW dealer performs the work.
Carbon buildup on intake valves
up to €6004 of 6
Direct injection causes carbon deposits on intake valves, reducing performance over time · more· less
Like all direct-injection engines, the B38 does not wash fuel over the intake valves, allowing carbon deposits to build up gradually. This causes rough idle, hesitation, reduced power, and increased fuel consumption. Becomes noticeable typically after 80,000-120,000 km, especially on cars used predominantly for short trips. Walnut blasting is the standard cleaning method, costing €350-600 at a specialist. Some owners treat this as preventive maintenance every 60,000-80,000 km. Using quality fuel and occasional spirited driving help slow the buildup.
Rear taillight earth wire failure
up to €3505 of 6
Ground wire in rear light cluster overheats and melts the connector, causing indicator failure · more· less
A well-documented F22-specific issue where the earth pin in the rear taillight connector carries too much current and overheats, melting the plug. This causes intermittent or permanent rear indicator failure and dashboard warning messages. BMW released a genuine repair kit (part number 61122448168) that adds an additional ground wire to distribute the load. The repair kit costs approximately €30-50 for parts, but if the entire light cluster is damaged, replacement costs €200-350. Pre-LCI cars (2014-2017) are more commonly affected.
VANOS solenoid clogging
up to €5006 of 6
Oil varnish buildup restricts flow to VANOS solenoids, causing rough running · more· less
The B38's dual-VANOS variable valve timing relies on oil-fed solenoids with fine mesh screens. Over time, oil varnish and particulate can clog these screens, restricting oil flow and causing sluggish camshaft adjustment. Symptoms include rough idle, hesitation, and occasionally a check engine light. This is more common on cars with extended oil change intervals or low-quality oil. Cleaning or replacing the solenoids typically costs €200-500 and is straightforward. Shorter oil change intervals (every 10,000 km rather than the 15,000-20,000 km that Condition Based Service can stretch to) largely prevent this issue.
Reliable platform, but the B38 three-cylinder needs attentive maintenance
The F22 2 Series is one of BMW's more dependable modern platforms, and the B38 engine can comfortably exceed 200,000 km when properly maintained. The key concerns are timing chain tensioner wear, turbo wastegate rattle, and cooling system components, all of which are well-documented and manageable with proactive maintenance. Short oil change intervals and quality synthetic oil are essential. The manual gearbox (Getrag GS6-17) is very reliable, and the ZF 8-speed automatic is robust with periodic fluid changes.
Service history
Complete BMW dealer or specialist records are essential. Verify oil change intervals are 15,000 km or shorter.
Tires
Check tread depth, age (sidewall date codes), and uneven wear. Rear tires wear faster on rear-wheel drive.
Cold start
Start the engine completely cold. Listen carefully for any rattling in the first 30 seconds.
Test drive
Minimum 20 minutes including town and motorway driving to get all systems up to operating temperature.
Specific for this vehicle
Listen for timing chain rattle on cold start
A rattle lasting more than 2-3 seconds on a completely cold engine indicates tensioner wear. This is the most important check for the B38 engine.
Check for turbo wastegate rattle at low RPM
Drive gently in Comfort mode at 1,500-2,000 RPM. Listen for a metallic rattling from the engine bay. Common on all B38 engines but assess severity.
Inspect coolant level and condition
Low coolant or discoloration may indicate coolant pump or thermostat housing issues. Check for residue around the thermostat housing area.
+ 3 more checksShow less
Test all rear indicators and taillights
Activate all rear lights and indicators. Check dashboard for light failure warnings. Earth wire connector failure is common on pre-LCI cars.
Check oil level and condition
Low oil between services suggests consumption issues. Dark, thick oil may indicate extended change intervals. Ask about oil change frequency.
Verify engine runs smoothly at idle
Three-cylinder engines have inherent vibration, but excessive roughness or misfires may indicate carbon buildup on intake valves or VANOS issues.
Contact BMW with the VIN to verify all recalls have been completed. The Takata airbag recall is especially important as it affects vehicles produced up to June 2018 and has been subject to multiple recall waves.
Warranty Status
Factory warranty (2 years, 3 years from Nov 2016)Expired on all used 218i F22 models

Rust perforation warranty (12 years)May still be active on 2015-2020 models
All BMW 218i F22 models are outside their original factory warranty. BMW's 2+1 extended warranty (introduced November 2016) applies only to cars purchased new from that date onwards. The 12-year rust perforation warranty may still cover body corrosion on newer examples.
