BMW N26 Engine: Execs, Cons and Reliability

The BMW N26 engine, typically in comparison with its sibling, the N20, was an integral a part of BMW’s push for extra environmentally pleasant powertrains again within the early 2010s. Launched as a “SULEV” (Tremendous Extremely Low Emissions Car) variant of the N20, the N26 engine powered a number of BMW fashions from 2013 to 2016. Regardless of their similarities, the N26 has notable variations designed to fulfill stricter emissions rules, significantly in states like California and New York, the place tighter emissions requirements apply.

On this article, we’ll discover the reliability, key variations between the N26 and N20 engines, advisable upkeep practices, and the professionals and cons of proudly owning a car outfitted with the N26 engine.

Key Variations Between the BMW N26 and N20 Engines

Whereas the BMW N26 and N20 engines share a 2.0-liter inline-4 turbocharged configuration and plenty of inner parts, they differ primarily in emissions know-how:

1. Emissions Tools: Essentially the most important distinction between the N26 and N20 is the emissions tools. The N26 is classed as a SULEV engine, which means it complies with a lot stricter emissions requirements than the N20 (which is classed as ULEV – Extremely Low Emissions Car). To realize this, the N26 is supplied with further emissions management parts, akin to bigger catalytic converters, an digital wastegate, and a modified PCV system.
2. Gas System: The N26 options steel gas traces as a substitute of the rubber ones discovered within the N20, and it features a valve within the gas tank venting system for leak testing.
3. Software program Tuning: The engine management unit (ECU) software program is calibrated in a different way to optimize efficiency and emissions for the N26’s particular {hardware}.Guarantee Protection: Due to the N26’s emissions parts, automobiles with this engine sometimes include an prolonged emissions guarantee, overlaying sure parts for as much as 15 years or 150,000 miles in states that observe California’s emissions requirements.

Mannequin Purposes:

The N26 was solely out there in 2013–2016 BMW fashions bought in emissions-restrictive states, together with California, New York, New Jersey, and others. The N20, then again, was extra extensively out there throughout all U.S. states and internationally.

• 2012-2016 F30 328i / 328iX
• 2012-2016 F22 228i / 228iX
• 2014-2016 BMW 4 Collection F32/F35/F36 428i SULEV

Regardless of these variations, each engines share the identical energy output: 241 horsepower and 258 lb-ft of torque, making efficiency indistinguishable below regular driving situations.

BMW N26 Reliability

In relation to reliability, the N26 inherits each the strengths and weaknesses of the N20, but usually, the N26 is taken into account a dependable engine. Listed below are the frequent reliability elements:

• Timing Chain: Whereas not as widespread as within the N20, timing chain issues can happen, resulting in expensive repairs. Common oil adjustments and checking the chain tensioner might help stop this. In line with some house owners, this difficulty sometimes manifests after 60,000 to 100,000 miles.
• Valve Cowl and Oil Filter Housing Gasket Leaks: These are frequent points in lots of BMW engines, together with the N26. Changing the gaskets is a comparatively simple restore.
• Excessive-Strain Gas Pump (HPFP) Failure: Although much less frequent than in earlier BMW fashions, the HPFP can fail within the N26, resulting in tough operating or a no-start situation.

Upkeep Suggestions for the BMW N26

Correct upkeep is crucial to make sure the longevity of the N26 engine. Listed below are the important thing upkeep suggestions and intervals for this engine:

1. Oil Modifications: Common oil adjustments are essential. BMW recommends oil adjustments each 10,000 miles, however many homeowners go for 5,000-7,500-mile intervals, particularly in harsh driving situations. Use high-quality artificial oil to maintain the engine operating easily.
2. Timing Chain Inspection: Given the timing chain points, it’s a good suggestion to have the chain and guides inspected at round 60,000 miles. When you hear a rattling noise coming from the engine, have it checked instantly.
3. Cooling System: Control the coolant ranges and have the water pump and thermostat inspected throughout common service intervals to keep away from potential overheating.
4. Emissions Parts: For the reason that N26 has further emissions tools, it’s vital to take care of these elements, particularly for house owners in SULEV states. Frequently examine gas traces, the catalytic converter, and the secondary air injection system.
5. Gasket Replacements: Be proactive about changing the oil filter housing gasket and valve cowl gasket as they will put on out over time, main to grease leaks.
6. Excessive-Strain Gas Pump: Keep vigilant for any indicators of HPFP failure, akin to tough idling or engine misfires. If the pump fails, it must be changed below BMW’s prolonged emissions guarantee if relevant.

General, the BMW N26 is a stable engine that provides a superb stability of efficiency, gas effectivity, and emissions compliance. There’s on main recall which occurred in 2013 and you may study extra about it right here.
