The first-generation N63, designated N63B44O0, was manufactured from 2009 to 2013, and is the front-runner for the title of BMW’s all-time least reliable engine. BMW even devised a “customer care package” to try to fix the mistake because it was so bad.
The timing chain, fuel injectors, mass air flow sensors, crankcase vent lines, battery, vacuum pump, and low pressure fuel sensor were among the necessary parts that needed to be replaced, but BMW refrained from calling the service bulletin a “recall,” allowing customers with and without warranties to have their N63s serviced. A class-action lawsuit was filed against the corporation immediately after the release of the service bulletin, thus the response was less than enthusiastic.

Mercedes is a brand with which we are less familiar, so we can’t really comment on it. In terms of the N63, the most recent model features an almost entirely new engine from top to bottom. The TU3 and original N63 engines share extremely few components.
In order to reduce cooling system problems and oil leaks, BMW has made several significant improvements to the cooling system and general engine design. Too little is known about the N63TU3’s long-term reliability as of yet. However, we anticipate that these engines will occasionally experience cooling issues and oil leaks as they age to 6 to 8 years and 80,000 miles or more. Consider the coolant hoses, oil pan gasket, valve cover, etc.
In our perspective, BMW is on the right track in terms of reliability. The N63tu3 is a fantastic engine, and with the right maintenance, it ought to be fairly trouble-free. Again, as they get older, some issues are sure to arise, but that is true of any engine or vehicle.
Should You Purchase An N63 BMW Today?
The legendary BMW N63 hasn’t undergone many significant changes in the last ten years, but BMW’s smaller inline-four and inline-six engines have. It’s improbable that the manufacturer has another V8 engine in the works given the rise of electric vehicles and BMW’s greater focus on more environmentally friendly powertrains. That implies that the N63 might be the final vehicle of its kind produced by the Bavarians.
You should obviously think about its dependability, but since the Customer Care Package covers the earlier models and the newer N63s are far more dependable right off the assembly line, this is as good a time as any to get your hands on one. However, as it’s a still-in-production engine, pricing for even a used version may be rather high. If you want to save some money, you might be better off waiting for a few years.
Making History With the BMW N63
The future appeared promising when it was released in 2008. BMW was taking a lot of chances by doing it this way, utilizing some intriguing concepts like the hot-vee (exhaust exits into the turbos on top of the engine, in the valley, rather than out the bottom). This design produced some complications that, in retrospect, perhaps would have been better left on the table, along with the now-common high-pressure direct injection system. However, there is no denying the excellent packing used for the engine bay.
The usage of air-to-water intercoolers rather than the more common air-to-air exchanger is one fascinating example of overcomplication. The intercooler piping will be significantly shortened and space will be saved as a result. The air-to-water intercoolers, however, have a separate coolant pump and reservoir, and THAT has its own radiator in the front of the engine because of how much heat is being produced. By doing this, one Tomahawk cruise missile fired from orbit effectively kills two birds with one stone.
Between 2008 and 2012, the 5-series, 6-series, 7-series, X5, and X6 models with names that end in “50” used the N63B44O0engine, which was the first N63 to launch. The likelihood of it getting to the shore was uncertain given the state of the technology. Soon after the company’s introduction, BMW owners began to voice their complaints about issues ranging from unusual oil usage and rough idle to outright breakdowns. In order to reduce the likelihood of having to repair complete BMW N63engines under warranty, BMW initiated a preemptive remedy campaign for the N63B44O0 engines because enough of them were arriving at dealers with serious powerplant issues.
How recently did BMW update the N63 engine?
From 2008 till the present, the twin-turbocharged V8 petrol engine known as the BMW N63 has been manufactured. The N63’s “hot-vee” architecture, with the turbochargers housed inside the “V” of the engine, makes it the first production automobile engine in the world. Additionally, it is BMW’s first V8 turbocharged engine.
A naturally aspirated V8 engine, the BMW N62 was succeeded by the N63, which made its debut in the 2008 X6 xDrive50i.
Which BMW V8 engine is the most dependable?
Engine 1B58 The BMW B58 engine, which is included in the 340i and M240i, was awarded one of Ward’s 10 Best Engines in 2016, 2019, and 2020. (M340i). Compared to the N54 and N55 engines’ first four years of use, the B58 engine seems to be more dependable.
BMWs still dependable after 100,000 miles?
BMW is renowned for producing opulent vehicles with outstanding handling and driving dynamics. Do BMWs still be reliable after more than 100,000 miles on the road?
JD Power and other reliability evaluations have routinely placed BMW among the top ten most trustworthy cars.
Furthermore, having driven a BMW myself, I can vouch to the reliability of these vehicles, even after more than 100,000 miles on them. Some models are trustworthy while others are not, therefore it also depends on the models. They require maintenance, but any vehicle that you want to keep in good running order requires maintenance as well.
It heavily depends on the circumstances. It has been said that several BMW models, including the E46 and the E90, can go more than 300,000 miles on a single charge.
This, however, depends on a number of variables. For instance, it’s possible that your car may need significant repairs after 100,000 miles if you don’t change the oil in it frequently or maintain it properly.
Which of BMW’s engines is best?
The M88, which powered BMW’s M1 supercar, was the company’s first M engine. It could produce somewhere between 215 and 282 horsepower with a redline of 6,500 RPM, which was a major thing when it was developed in the late 1970s. Additionally, it was employed in the BMW 3.0 CSL, which competed in the Group 5 race series and produced more than 800 HP at 9,000 RPM.
It was a strong engine that made one of the most beautiful engine sounds ever.
How can you tell whether your engine is an N63TU?
If I am correct, the 550i motor was replaced with an N63tu for vehicles built on or after August 13, 2013. When I check at all of these 2013 models online, many of them don’t include the horsepower. Is there a feature (external design or notation in the VIN) that sets the N63tu motor apart from the N63?
The Life Cycle Impulse (LCI; a facelift model) and the N63TU engine for the F10/11 were both introduced in July 2013. the power is 330 KW (Kilowatt), which translates to 449 hp in continental Europe or 440 hp in the US, and torque of 650 Nm (480 lb*ft). The differences from the N63 are significant.
At the very end of July, the changed over. My 2013 was constructed on July 27 and I believe it may have been the last n63 constructed, or very close to it.
If you’re unsure which engine is installed, you can run the VIN and find out.
however I am certain that all 2014 models have it, and they also received a facelift, so I chose a 2014.
What BMW engine has the most power?
The most potent engine installed by BMW M GmbH is found in the BMW M5 CS. The 4.4-liter V8 with M TwinPower Turbo technology produces a peak torque of 750Nm between 1,800 and 5,950 rpm and 635 horsepower at 6,000 rpm.
What is a typical BMW engine issue?
System of Engine Cooling Overheating is a problem that many BMW owners frequently experience. A qualified automotive technician will be able to assist you identify the issue even though there are several components in your car that might be the cause of this problem, such as a leaking water pump or coolant.
Which vehicle has an N63 engine?
Ahead of its time, the BMW N63 V8 engine produces 408 horsepower and 440 ft/lbs of torque. The BMW 550i, X5, X6, 750i, and 650i all had this engine. Although these cars offer a fantastic balance of luxury and athleticism, the BMW N63 engine nevertheless needs careful maintenance to operate at its best.
Which BMW engine is having issues with the timing chain?
Many BMW customers now have a major issue with premature timing chain breakdown, which is frequently discussed in BMW internet forums, mentioned on BBC Watchdog, and highlighted on other media websites.
A timing chain design issue seems to impact a variety of BMW diesel engines built between 2006 and 2015. The engine timing chain is exceedingly fragile; over time, it stretches and eventually snaps.
BMW timing chains have broken on a variety of 1, 3 and 5 Series models, most frequently the N47 diesel. In addition, we restore BMW petrol engines, M57 and N57 diesel engines, and BMW Minis.
The timing chain is at the back of the engine compartment and is not meant to be repaired.
How far do BMWs travel before problems arise?
Although we think BMWs are dependable vehicles, there are a few main problems that affect the vast majority of BMW vehicles and BMW engines. A number of these issues begin to surface between 80,000 and 120,000 miles. Conveniently, there are a ton of used BMWs available that are close to this mileage and are considerably less expensive initially. Some customers purchase these vehicles without being aware of the problems, and they rightly become angry when they receive $1,000 maintenance bills soon after purchasing their BMW. A few things to watch out for are as follows:
- Electricity Problems
- Oil Spills
- Probleme with dem Kühlsystem
This is not a comprehensive list, and some specific BMW models might have additional frequent problems while other models might not have any of the aforementioned frequent problems. However, the most well-known and frequent difficulties are oil leaks, cooling system problems, and electrical problems.
How much does an N63 engine replacement cost?
Ghassan Automotive can replace your BMW engine if you need to or can upgrade the one you currently have. From the moment we pick up the entirely refurbished BMW N63 / N63TU engine for $8,495, which comes with a two-year, unlimited-mileage guarantee, the process is hassle-free.
What is the weight of the N63 engine?
On this, I can’t find any information at all. I tried searching for it on Google and here, but to no effect. I don’t believe BMW has made any public statements about the engine’s weight. Even the N63 or S63’s weight is nowhere to be found. Just curious for comparison’s sake considering the S85B50’s 529-pound dry weight.
BMW S85 is 240 kg heavy. The 228 kg BMW N63 weighs. The sophisticated turbosystem in the S63 may make it weigh significantly more. BMW won’t say how much it weighs because it wants us to remember that smaller turbocharged engines are lighter than larger naturally aspirated ones. This is not true for engines with high performance levels, or it is only true for engines with extremely high power outputs, which are only appropriate for racing and not for use on public roads.
Can an N63 handle a lot of power?
An amazing engine with competent dual turbochargers is the N63tu. In general, they can withstand 25 psi or more. However, that exceeds the efficiency range of the original turbos. For a decent blend of durability and performance, we advise 20 psi. Of course, there is still a chance. However, we think that 20 psi is long-term viable with adequate tuning and accompanying modifications.
One more thing to think about: N63tu’s operating at higher altitudes might want to pull out a few PSI. To be safe, try to make up part of the power with improved fuelling, tune, or supporting modifications.
