The N20 engine is generally dependable, but the earlier models frequently have timing chain problems that can be expensive to correct. Not every engine will encounter problems permanently just because some engine faults are widespread. N20 engines are also prone to a wide range of other problems, which we won’t categorize as common problems because they might only occur on a small number of engines. What then are the BMW N20’s most frequent problems?

BMW N20 reliability vs. B48
The N20 and B48 engines should both be dependable. There is a known issue with the timing chain in the N20. Due to the expensive repair and potential for significant engine damage, it is a pretty serious problem. The N20 is otherwise troubled by usual BMW problems. These include problems with the cooling system and leaking gaskets on the valve covers, oil pans, and oil filter housings. However, these problems typically don’t surface until 80,000 to 100,000 miles or more.
The B48 seems to be the more dependable engine thus far. To yet, the B48 has not experienced any significant common issues. However, absent the timing chain, we anticipate that the B48 would soon experience similar widespread issues as the N20. Not that either engine is unreliable, though. Repairing a gasket oil leak can be quite expensive. Nevertheless, these are inexpensive fixes for the DIY population (though time consuming repairs).
Common Machine Cases for BMW N20
Although the N20 is a good engine overall, the earlier models have a lot of timing sequence issues that could be expensive to fix. They will indefinitely catch developments for each engine, regardless of how many of the engine developments are unimpressive. Additionally, N20 engines are vulnerable to multiplexing various occurrences that we would not see as unremarkable changes since they could result in a sawed-off group of engines. What are the BMW N20’s most well publicized developments overall?
Hi,
Could someone please explain the condition of this engine and whether we should purchase the vehicle?
The N20 from that year is good. The engine is as dependable as any BMW has recently produced, especially after BMW fixed the two flaws it did have when it was first introduced in 2011: that timing chain and the fuel pump. However, unless your father plans to tune the car to within a hair’s width of its design tolerances, the motor is as reliable as any other BMW has recently produced.
“Blackened” ’18 NBM Porsche 718 Cayman at the moment… “Blackened” MG ’15 228i M Sport with aFe filter/scoop, Hertz drivers, P3Cars multigauge, and other luxuries have vanished (but not forgotten)>>
Due to its issues, the timing chain was modified for the 2015 model year. Along with the gasoline pump, the 2012–14 versions were subject to recalls to fix this problem. Despite having only 13K miles on it, my 2015 hasn’t lost a beat. It is, in my unqualified view, a fantastic engine. strong and torquey with good fuel efficiency. Try it out.
The vehicle still has 14 months of warranty remaining; its 28K miles are equivalent to 15K kilometers.
I’m not sure about Canada, but it is definitely not the case in the US. The original warranty is transferred to the new owner, and any time before that original warranty expires, the new owner can pay BMW to CPO the vehicle through 75K or 100K.
Should I purchase a N20 BMW?
Obviously, as cars get older, it is impossible to predict which parts would eventually fail because practically every part is subject to wear and tear. However, the following difficulties are also very likely:
- Heater hoses
- Chargepipe
- lines of vacuum
- Solenoids of Vanos
Overall, the BMW N20 is a dependable engine with few typical problems that should raise alarm until greater usage. Many of the repairs suggested are affordable for do-it-yourselfers because the cost of the parts is not prohibitively high. Some of the repairs are time-consuming and labor-intensive, so the prices may build up for shop patrons.
Which BMW models run on the N20 engine?
- E84 X1 xDrive/sDrive20i from 2011 to 2015.
- F25 X3 xDrive20i 2011–2017
- 2012-2015 F30 320i.
- 2013-2016 F34 320i GT.
- 2014-2016 F32 420i.
- 2011-2016 F10 520i.
- 2013-2016 F10 520Li.
- E89 Z4 sDrive20i from 2011 until 2016.
Which BMW model is the most dependable?
When it comes to the creation of sport sedans, BMW has established the benchmark for premium vehicles with the E90 330i that Acura and Volvo aspire to match. The BMW E90 330i is your best option if you’re looking for a sedan that provides the ideal balance of functionality and performance without sacrificing stability and comfort.
The BMW E90 330i is one of the most popular luxury vehicles in the United States and is not only the best-selling model in the 3 Series. It also sold over 336,232 units. Even in the mid-size luxury automobile category, the BMW 3 Series received the Top Safety Pick designation in 2006. The best car options in terms of driver injury prevention and driver restraint features are highlighted by this award.
A BMW N20 uses how much oil?
Engine oil can be stored in 5.3 quarts in the BMW N20. You’ll require this number when it’s time to change your engine’s oil.
Depending on the model, the BMW N20’s turbocharged four-cylinder petrol engine has a 1.6L or 2.0L engine displacement. From 2011 until 2018, the N20 was installed in numerous BMW vehicles.
The 1.6L or 2.0L number has nothing to do with how much engine oil your engine can retain because engine displacement and oil capacity are two different things.
When did BMW repair the N20 timing chain?
The main development in this case is that BMW revised the timing chain’s component designs. just how? We can presume that N20 and N26 engines with construction dates of 2015 contain the upgraded timing chain and components because RealOEM indicates that there was a part number change for the N20 Timing Chain starting on 01/2015.
The N20 has a dual turbo?
The N20’s inline-four engine was equipped with a twin-scroll turbocharger, double-VANOS (variable valve timing), Valvetronic (variable valve lift), an electric water pump, and direct injection. These features were first introduced on inline-four engines like the N40, N42, N46, and N13, which were not sold in the United States, over the previous ten years. By the time it was introduced to the N20, it had a good reputation for dependability.
Depending on the vehicle it was used in, the N20 was mated to either a 6-speed manual or an 8-speed ZF automatic transmission. This engine had a lot of torque compared to its predecessor, partly because to its undersquare, long-stroke design. For comparison, the N20 delivers 60 lb-ft more torque than the N52 did on the Z4! Additionally, it enters the rev range almost 1,500 rpm earlier.
BMW claims that by optimizing the N20, fuel economy was raised by an astonishing 20%, making it more efficient than the N52.
Can you speed up a BMW 320i?
It’s hardly surprising that one of the most prevalent European vehicles on New Zealand roads has been the BMW 320i. It’s because they are reasonably priced, fashionable, and low maintenance.
But the most frequently requested question about the BMW is usually the same: “Can you make my BMW 320i faster?” For the previous ten years, the response was virtually invariably a categorical “no.” We may perform simple 320i tuning tactics, such as enhancing the accelerator responsiveness, taking care of the maintenance, and regaining lost horsepower over time. Not much more than that, though.
The 320i requires some sort of forced induction for years in order to move. Our hopes were ultimately granted when BMW released the F30 320i with a turbo in late 2011 or early 2012. The excellent interior, fantastic gearbox, and N20 engine with a little kick to go with it made it an instant hit.
People began to realize that the BMW F30 328i had the same engine in the following few months, but that the power output was significantly higher.
What BMW models are prone to timing chain issues?
Your car may have a timing chain issue if you possess a BMW model from any of the BMW 1, 3, or 5 series produced between 2007 and 2011. Due in significant part to the usage of the more recent N47 motor engine, the high-end German vehicles are vulnerable to an unique engine issue known as timing-chain wear.
How durable are B48 engines?
It can be difficult to talk about longevity, and the B48 is no exception. A portion of it is purely dependent on chance, upkeep, etc. Most BMW B48 engines’ internals ought to last for more than 200,000 km. The timing chain, cylinder head, and other components are comparable. At 150,000 miles or more, though, routine maintenance and repairs may begin to pile up quickly.
How durable are BMW timing chains?
The second is the 4-cylinder, normally aspirated and turbocharged petrol N12, N14, and later N16, N18 engine that was installed in the MINI Cooper and S models from 2006 to 2016.
Often, if the timing is allowed to jump too late, the exhaust valves will flex. Therefore, if the engine rattles after starting from cold, it is preferable to replace.
Due to damaged valve stem seals that allow engine oil to vacuum bypass into the cylinders, these engines are also vulnerable to excessive engine oil consumption. It is advised to replace the valve stem seals when the engine is disassembled to replace the timing chain. This will spare labor for this separate repair down the road. We have a unique tool that makes it possible to repair the valve stem seals without taking the cylinder head off.
The drive belt for the alternator may occasionally be cracked or worn out from aging. While this is being removed, it is advised that you replace it.
In some circumstances, we demand a labor deposit to reserve a timing chain replacement (often roughly 50% of the entire repair cost). This is because there have been so many appointments in the past that were cancelled or missed.
