The N55 was BMW's first straight-six engine to use a twin-scroll turbocharger.

No issues. The new turbocharged unit, which can develop more than 7,500 rpm, combines the best of both worlds – on the one hand a high-revving design for instant response, linear power delivery over a wide engine speed range and an unmistakable and characterful engine note, and on the other hand BMW TwinPower Turbo technology for maximized torque over a broad rpm range. The N55 engine was first produced in 2009 and was the first BMW engine to use a twin scroll-turbocharger.While variations of the N55 are still in production and use today they began to faze them out of BMW vehicles after BMW introduced the B58 engine in many of their newer models.. And instead of liners, the cylinder bores feature a twin-wire arc-sprayed coating, which results in a significant reduction in engine weight.The six-cylinder engine features a closed-deck crankcase design, which increases rigidity and allows cylinder pressures to be increased for maximised power output. The N55 replaced the BMW N54 engine and was introduced in the F07 5 Series Gran Turismo.

The Problem At the same time, throttle response is even sharper than before..The six-cylinder engine features a closed-deck crankcase design, which increases rigidity and allows cylinder pressures to be increased for maximized power output. The Biturbo was mid-2014 in the new BMW M3 (F80) and BMW M4 (F82) introduced. Under extreme longitudinal acceleration and deceleration, an oil extraction pump and a sophisticated oil return system situated close to the turbocharger likewise help to maintain uninterrupted oil circulation. The new BMW M3 Sedan and new BMW M4 Coupe from BMW M see a return to a six-in-line engine configuration, as used on the second and third generations of this iconic sports car. Daily driver since it returned to me from ED in Nov 2014 (picked up Sept 2014) and honestly not a single issue other than getting a spurious 'drivetrain malfunction' after rapidly choosing DCT reverse and engaging throttle too fast apparently (shutdown and reboot and never seen again)! Mine came with this defect from the factory and needed to be replaced after 60 miles. Here are some common problems that any N55 Bmw car has shown over the years with or without a software tune installed on the factory engine management system (ECU/PCM/ECM) . Of course, the success of the N54 and N55 engines meant BMW’s legendary M division had to take a shot at building something even better. S55 is known to sound like poo. Something about a hub crank? How do charge pipes hold up on the S55? For those in the market looking to purchase a BMW 135i, 335i, or 535i one important aspect to consider is reliability. BMW S55 engine is a high performance version of the N55, which is used by the F80 M The variable valve and camshaft timing provide fully variable control of intake valve lift. The low-weight magnesium oil sump, for example, features a special cover to limit movement of the oil under the effects of strong dynamic lateral acceleration. Oil is therefore supplied continuously to all engine components in all driving situations – whether in everyday motoring or during hard driving on the track.BMWBLOG is an independent private enthusiast site dedicated to BMW fans around the world and is in no way affiliated or owned by BMW USA and/or BMW AGContinue Reading Below Not from when you unlock the doors. The new powerplant also boasts excellent fuel consumption, with an improvement of more than 25 per cent over the previous model’s figures, while emissions are already EU6-compliant.Six-cylinder in-line high-revving, turbocharged engine.The new BMW M3 Sedan and new BMW M4 Coupe from BMW M GmbH see a return to a six-in-line engine configuration, as used on the second and third generations of this iconic sports car. This allows the engine to deliver its power smoothly and efficiently, resulting in lower fuel consumption and emissions. Some people have had issues with the valvetronic motors in the S55 and their incessant clicking every time the car is unlocked after having sat for several hours.

Biggest issue I know of with the S55 is how it sounds

Its also known to be rather potent and reliable. Are you a new Bmw owner and your car is equipped with the n55 engine?

A Little More About the N55 Engine. Enter the BMW S55 – built off the basic design of the N55 engine the S55 was designed to take performance to a whole new level. Possibly crank hub on esrlier cars?On initial startup right. There is a LOT of data on this engine, so you’re in luck if you love those juicy details. A new BMW Six-Cylinder Engine, codename S55, makes its way under the hood of the new BMW M4 and M3. And instead of liners, the cylinder bores feature a twin-wire arc-sprayed coating, which results in a significant reduction in engine weight.The exceptional performance of the BMW M3 Sedan and BMW M4 Coupe also demands an exceptionally sophisticated thermal management system for the engine and ancillary units. The BMW N55 is a turbocharged straight-six petrol engine that began production in 2009.
