The 2008 335i I now own has 90,000 miles on it and is still going strong. I just wanted to know how much it would cost to replace the turbos if they failed. For the next 9,500 miles, I have a third-party warranty that covers bumper to bumper, so I was just curious how much it would cost at a BMW dealership versus an independent mechanic.

How durable are the BMW 335i turbos?
The BMW N54 engine’s OEM turbochargers have a number of somewhat frequent modes of failure. It is essential to replace your failed turbos with new OE units the first time because doing so is not a simple operation.
The BMW N54’s turbochargers typically survive for roughly 100,000 miles before needing to be refurbished or replaced. It is typical to hear of automobiles with original turbos that have over 200,000 miles on them and are still operating as intended. However, the BMW N54’s turbo failure is so common that class-action lawsuits and service advisories have been published by BMW as a result of the failures. Unfortunately, the solutions to these problems—whether extended warranty replacement or other—do not apply because the product is now over twelve years old.
There are a few indicators that your BMW 335i/xi/is with the N54 engine needs new turbochargers. The first and most typical symptom is a loss of power or misfiring caused by a defective wastegate. The wastegate eventually gets so flimsy that boost leaks are possible. You will usually hear a distinct rattling or chatter when things get extremely bad.
If you’re burning oil and seeing white smoke coming from your exhaust, it’s another indication that your turbochargers need to be replaced. Because the seals on these Mitsubishi turbochargers are oil-lubricated and coolant-cooled, you will notice coolant or oil burning if the seals start to fail. If that’s the case, either the cooling or lubrication of the turbo is insufficient, which will eventually lead to total failure of that turbo.
We sell the brand-new OE replacements for the front and rear turbos for your BMW 335i/xi/is rather than the remanufactured units from BMW if you’re in the market for new turbos. Due to the effort needed to get access to them, we advise replacing the second turbo at the same time that you replace the first. We offer a complete installation kit to make the process even simpler. The kit includes everything you’ll want to change when you swap out the two turbochargers.
Our BMW Catalog Manager, Gareth Foley, guides us through typical failures, symptoms, and why it’s crucial to replace the turbos if you notice failure signals in the video down below. If you enjoyed this Really Quick Product Review, subscribe and come back soon for new episodes.
all 335i models twin turbo?
From 2007 through 2015, the BMW 335i was a viable option. The N54 and N55 were the 335i’s two main engines. The two engines each have a 3.0L inline-6 turbocharger. The N55 engine only has a single twin-scroll turbo, whereas the previous N54 engine uses two turbos. Despite having different turbos, the majority of BMW 335i vehicles produce the same 300 hp and 300 lb-ft of torque. In this post, we analyze the horsepower and torque of the 335i according to various periods and talk more about the cars’ potential horsepower.
How much does a N54’s turbo replacement cost?
I don’t know how much money to save aside for a new turbo kit for my car because I’m new to the field of performance modifications. What is the price of a BMW N54 single turbo kit?
The cost of a turbo kit might vary greatly depending on the model you choose. Depending on the model, a BMW N54 single turbo kit might run you anywhere from $800 to more than $8,000. Single-turbo kits typically range in price from $1,000 to $3,000.
High-end turbo kits with more cutting-edge technology typically cost more, as you might anticipate. Although single-turbo kits are more common because they are often less expensive than twin-turbo kits, both achieve different performance objectives.
While single-turbo kits build power more slowly but perform better at the top end, twin-turbos are especially good at eliminating latency.
Make sure the turbo kit you select for your BMW N54 engine is compatible with your car before purchasing it. Additionally, given that the BMW N54 is already a technically dual-turbocharged engine, you need absolutely ensure that the person handling your upgrade has the mechanical know-how to do the conversion to a single turbo. An improper installation or the selection of the incorrect turbo kit could result in engine or other vehicle component damage.

How much does installing pure Turbo cost?
Without a doubt, it takes 10 to 11 hours. With tax, fluids, and gaskets included, you should anticipate paying between 1300 and 1500 depending on the business. Additionally, a $200 Pure install kit is required, and I also advise purchasing the diverter valve and inlet, which have corresponding prices of $135 and $275.
What is the price of a single turbo?
Depending on the make and model of your car, a turbocharger normally costs $400 and goes higher from there. You should anticipate paying less for a replacement turbocharger if you own a smaller vehicle like an Audi A4 or a Subaru Impreza. A replacement turbocharger for a large truck or sports vehicle will cost well into the thousands of dollars. And if you own a tractor or an industrial vehicle, the cost of a replacement turbocharger is virtually unaffordable.
Why do BMW turbos break down?
The primary reason for turbocharger failure is oil-related, typically as a result of either low oil levels or soiled oil. The lengthy oil service intervals appear to be the root cause of turbocharger failures in BMW vehicles. (Depending on when the car’s indication suggests to perform it, the dealer normally advises oil changes every 12,000–18,00 miles.)
Is the 3.0 Twin turbo BMW engine reliable?
2020 Wards 10 Best Engine and Powertrain Award winner is the BMW B58 TwinPower Turbo 3.0-Liter Inline Six-Cylinder Engine, which produces 382 horsepower. BMW B58’s 3.0-liter engine has won the Wards 10 Best Engine title twice in a row. BMW Turbo’s 3.0 liter inline 6-cylinder won the 10th Wards 10 Best Engine award.
What amount of power can a 335i automatic handle?
As a result, if you keep your 335i auto off the track and avoid hard launches with sticky tires, maintaining it at 400 to 450 whp is probably safe for our trannys.
How durable are N55 turbos?
It’s challenging to estimate this with precision. In general, more boost will shorten the stock N55 turbo’s lifespan. N55 turbos, for instance, have been known to run 50,000 miles or more when operated at 23 psi. However, even at 20 psi, the stock turbo may opt to go off significantly sooner. You must be willing to take some risk in order to drive the N55 turbo to its breaking point. However, a relatively safe limit for the stock turbo should be around around 20psi.
Once you exceed 21 psi, you start to leave the N55 turbo’s efficient operating range. In other words, you would be increasing the turbo’s workload significantly for rather small performance benefits. Feel free to use the stock turbo if an upgrade is on the horizon for you. Before deciding to let go, it will likely continue to produce more boost, possibly even up to 26–27 psi.
N54 turbos fail, why?
The N54 Wastegates degrade due to straightforward engine wear and tear. The turbocharger’s actuator and rods deteriorate over time, which causes rattling and problems with boost control. In this situation, running your turbochargers at higher boost pressures (psi) will probably increase the likelihood of Wastegate failure. This implies that using a JB4, Cobb, or PROcede tuner increases the risk of blowing your turbos. This is due to the fact that the additional boost pressure produced by these tunes exerts more stress on the turbochargers, hastening wear and tear.
When the turbo fails, can you still operate the vehicle?
Over 4 years have passed since this article was published. Some information might not be up to date anymore.
In my 2009 Audi A4, the turbocharger quit operating. Can the automobile still run without it, and does driving the car harm it? – Gabriella
Your turbocharger is a turbine/fan device designed to increase the pressure of the incoming air into the engine. It is powered by the exhaust gases from the engine. The term “forced induction” refers to this pressure boost, which is utilized to increase engine production and efficiency. The simplest way for a turbocharger to fail is with an air leak, which prevents pressure from developing, or with a broken waste gate actuator, which is part of the control system and can result in an under- or over-boost state.
Although the car can still run without a turbocharger, it will perform poorly, and your choice might have far-reaching effects.
Complete failure is imminent if there is a problem with the oil supply or internal parts. Unfortunately, as it fails, the engine will eat all the debris left over from the catastrophic incident, resulting in a complete financial catastrophe.
On this one, you should err on the side of caution and fix the car. This is one of those occasions where looking around for a reasonable price is advised.
What symptoms indicate a turbo failing?
- Loss of power. If you notice that your automobile isn’t accelerating as quickly as it once did or is taking longer than usual to respond to your input, your turbo may be malfunctioning.
- Engine whine.
- ESCAPE SMOKE.
- VERIFY THE ENGINE LIGHT.
- OIL/LUBRICATION.
- BROKEN SEALS.
- FOREIGN DEPOSITS/OBJECTS.
- WORN AND TEAR
What HP capacity does a stock N54 have?
On the stock block and internals, the N54 can handle roughly 600–650 whp and 550–600 wtq. Later in the post, we’ll go into more detail on this. We’re keeping it straightforward for the time being, but this following sentence is crucial.
Estimates for the stock N54 engine’s upper limitations. The statement “the N54 will run for decades at 600whp, but it will blow up instantly at 651whp” is not accurate. Risk still exists. In all other respects, the danger you take increases with the amount of power you apply to the N54.
