What is the 2014-2025 BMW 2 Series Electric Coolant Pump Motor/Controller Failure Causes Overheat and Limp Mode?
The F22/F23 2 Series uses an electrically driven coolant pump (not belt driven) on N20/N26, N55 and B48/B58 engines. The pump's integrated electronics fail — owners and independent shops trace it to a failing capacitor on the dry side of the pump that takes out the motor controll… Repairs typically run $600-$1,300. Severity: high.
What is the 2014-2016 BMW 2 Series 228i Water-Pump Connector Fire Recall Requires a VIN Check?
NHTSA recall 24V-608 includes certain 2014-2016 BMW 228i and 228i xDrive vehicles. In the recalled population, fluid intrusion at the electric coolant-pump connector can cause an electrical short and localized overheating, increasing fire risk. The recall is VIN-specific and is n… Severity: high.

BMW SIB 11 03 17 includes F22/F23 228i and 228i xDrive vehicles with N20 or N26 engines produced through February 2015. It extends limited warranty coverage for the timing-chain and oil-pump-drive-chain modules but does not say every vehicle is defective or authorize replacing a… Severity: high.
What is the 2014-2015 BMW 2 Series Head Airbag Inflator Weld Failure Recall - 2014-2015 2 Series Coupe?
BMW recalled 2014-2015 2 Series Coupe models (228i, 228i xDrive, M235i, M235i xDrive) along with certain 2014 3 Series and 4 Series cars because the head (curtain) airbag inflator can fail at a weld joint. A failed weld can let propellant gas escape so the curtain only partially… Repairs typically run $0-$0. Severity: high.
What is the 2014-2021 BMW 2 Series Valve Cover Gasket Oil Leak?
The valve cover gasket on both N20 and B48 engines in the 2 Series degrades over time, causing oil leaks from the top of the engine. Oil seeps down the sides of the engine and can reach the exhaust manifold, creating a burning oil smell and potential fire hazard. The integrated v… Repairs typically run $500-$1,100. Severity: medium.
What is the 2014-2016 BMW 2 Series N20/N26 Electric Wastegate Actuator Rattle - Cold-Start Clacking from the Turbo?
On 2014+ N20/N26 cars (including the F22 228i) BMW switched from a vacuum wastegate actuator to an electric wastegate actuator (EWG). Over years of heat cycling the wastegate flap, its shaft and the bushing it pivots in wear and develop play. Exhaust pulses then shake the loose f… Repairs typically run $400-$2,200. Severity: medium.
What is the 2014-2021 BMW 2 Series Turbo Charge Pipe Failure - F22/F23 228i/230i/M240i?
BMW uses plastic charge pipes (boost pipes) to route pressurized air from the turbocharger to the engine intake. The plastic becomes brittle over time from heat cycles and boost pressure. The pipe commonly cracks or connection points fail, causing sudden loss of boost pressure an… Repairs typically run $150-$600. Severity: medium.
What is the 2014-2025 BMW 2 Series Direct-Injection Intake Valve Carbon Buildup - Misfires and Tip-In Hesitation?
Every US 2 Series engine (N20, N26, N55, B46, B48, B58) is direct injected, so no fuel washes over the back of the intake valves.
