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 satisfy 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 geared up 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 elements, they differ primarily in emissions know-how:

1. Emissions Gear: Essentially the most vital distinction between the N26 and N20 is the emissions gear. 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 provided with further emissions management elements, resembling bigger catalytic converters, an digital wastegate, and a modified PCV system.
2. Gas System: The N26 options steel gasoline strains as an alternative of the rubber ones discovered within the N20, and it features a valve within the gasoline tank venting system for leak testing.
3. Software program Tuning: The engine management unit (ECU) software program is calibrated otherwise to optimize efficiency and emissions for the N26’s particular {hardware}.Guarantee Protection: Due to the N26’s emissions elements, automobiles with this engine sometimes include an prolonged emissions guarantee, protecting sure elements for as much as 15 years or 150,000 miles in states that observe California’s emissions requirements.

Mannequin Purposes:

The N26 was solely accessible in 2013–2016 BMW fashions offered in emissions-restrictive states, together with California, New York, New Jersey, and others. The N20, however, was extra broadly accessible 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 beneath regular driving circumstances.

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 here are the frequent reliability components:

• Timing Chain: Whereas not as widespread as within the N20, timing chain issues can happen, resulting in pricey repairs. Common oil adjustments and checking the chain tensioner might help forestall this. In accordance with some house owners, this challenge 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-Stress 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 important to make sure the longevity of the N26 engine. Listed here are the important thing upkeep ideas 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 circumstances. 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. Should you hear a rattling noise coming from the engine, have it checked instantly.
3. Cooling System: Keep watch over 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 gear, it’s necessary to take care of these elements, particularly for house owners in SULEV states. Usually examine gasoline strains, 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’ll put on out over time, main to grease leaks.
6. Excessive-Stress Gas Pump: Keep vigilant for any indicators of HPFP failure, resembling tough idling or engine misfires. If the pump fails, it needs to be changed beneath BMW’s prolonged emissions guarantee if relevant.

General, the BMW N26 is a stable engine that gives a great stability of efficiency, gasoline effectivity, and emissions compliance. There’s on main recall which passed off in 2013 and you may be taught extra about it right here.
