According to INPA, Injector 2 on my 320d is about to fail and needs to be replaced.
One short question: are the injectors exclusively secured by the M headed bolts, as I noticed after watching a few YouTube lessons on M47 and M57 diesel injector removal?
I am aware that for Ford diesels, a special socket to fit around the injectors’ neck is advised, but from the tutorials, it doesn’t appear that this is the case with BMW diesels.
If you’re lucky, removing injectors won’t take much work. although in the majority of cases, a slide hammer is required to fit the M14 connector. I made use of one from eBay. https://www.ebay.co.uk/itm/vidaXL-Di…kAAOSwtT1gXyQr
The car took a while to start, but once it did, everything appeared to be in order when I checked INPA after programming the new injector.
The automobile idles smoothly. It runs smoothly up to 2200 rpm, at which point there is a pretty severe missfire, the RPM needle wobbles, and it feels like the clutch is slipping, even though I just had the clutch changed two years ago.
Could it be something like the MAP or has the MAF wiring been disrupted given that the manifold had to be removed?

What is the price of replacing the injectors in a BMW?
The cost of replacing your fuel injectors will vary depending on the make and model of your car. Fuel injector replacement often ranges in price from $800 to $1500, depending on the repairs and labor charges.
The price of new fuel injector parts can range from $600-$1200. Expect to pay between $200 and $250 in labor costs for that.
Nevertheless, keep in mind that you aren’t always need to replace the fuel injector. Your mechanic might occasionally just suggest giving the fuel injection system a good cleaning.
Can you clean BMW fuel injectors?
You only need to conduct a fast online search on “fuel injector cleaning” to know there are an absurd number of goods and services available. A professional ultrasonic cleaner and tester can cost over $1000, while simple pressure “no injector removal” tools can be purchased for as little as $100. The choice is made even more difficult by the various opinions and reviews that are dispersed over car forums. Many BMW and MINI home mechanics give up and simply install new fuel injectors to avoid having to clean them at all.
This is the main point. You can clean your BMW’s fuel injectors just as well as any professional service for less than $20 if you know how to remove them from the vehicle (which is very simple for most models). Yes, $20 is exactly what you read. If you are a home mechanic working on your own vehicle, there is absolutely no need to invest in an expensive professional fuel injector cleaning kit. These equipment are excellent for repair facilities that clean hundreds of injectors annually, but they are not cost-effective for do-it-yourselfers working on a single vehicle.
Does coding for BMW injectors exist?
Do I need BMW’s assistance to re-code if I replace one of my fuel injectors with the same model (part number 13537585261) that is currently on my car?
The newest fuel injector part number, which I discovered, is [FONT=’Calibri’,’sans-serif’].
13538616079, however vendors continue to provide the older model.

After replacing an injector, I took it to an ind shop a few months later for other work and asked them to code the injector; however, they were unable to do so. I regularly drive the car and have taken it to two track days. I don’t notice any issues or a difference in how the car drives.
You require INPA! I downloaded it for free from a post, and I paid about $40 for a cable on eBay. Code injectors are only one of the many things it can accomplish. They must be coded so that the ECU is aware of the injector’s flow rate and voltage. If you’re lucky, you might be able to replace it with an injector that has comparable specifications (-0.1 or +0.1), and you wouldn’t necessarily need to code them. Each injector has slightly varying working characteristics and contains a unique piezo-electric element that regulates the fueling, necessitating the need for coding.
What would happen if I replaced it with a similar sort (same part number) and did not re-code it? Would it give an error code (i.e., turn on the SES light) or just have one cylinder run in less-than-ideal conditions (which I can live with)? Anybody with certainty? I’ll probably try to find out. Thanks.
It’s possible to run that one cylinder richer or leaner. You only get one oxygen sensor for three cylinders, so even a 3% error would be around half a point of AFR.
For instance, if your new injector had a lower flow rate, the ECU would still supply fuel to all three cylinders on that oxygen sensor, but that one would still be somewhat richer than the other two. In that one cylinder, there may be explosion or significant ignition correction. If the problem is severe enough, it could result in a CEL, misfires, etc.
How durable are BMW fuel injectors?
Your gas tank’s fuel must be transported to various parts of the engine where it will be burned and used to propel the vehicle. You should take very seriously the need to ensure that the fuel is delivered appropriately. Typically, lines will carry the fuel from the tank to the fuel injectors, where it will be distributed. The engine will have a separate fuel injector for each cylinder. A fine mist of fuel will be released, making it more simpler to use and burn during combustion. The fuel injector is utilized to supply the engine with the power it requires each time you start and drive your car.
Your car’s fuel injectors will normally last 50,000 to 100,000 miles. The type of gasoline used in the car and how frequently the various fuel filters are replaced both have a significant impact on how long the injector lasts. The fuel injectors will typically become gummed up if you use lower grade gas. There are several injectable therapies available that can aid in removing these kinds of deposits. Eventually, no amount of treatment will be able to restore the injectors to their original condition; they must be replaced. An engine might suffer greatly from a bad injector, which means it needs to be replaced right away in it to operate again.
Your engine would not function properly without the fuel injectors, which are an essential component. Given the harm it may do to your engine, the last thing you want to do is disregard the warning signs that the fuel injectors need to be replaced.
Does removing fuel injectors require a specialized tool?
Depending on your car, you might be able to do it yourself or you could need a fuel injector puller tool. A puller can assist with gasoline injectors that are unusually shaped, albeit the shape and size of the tool may vary based on the fuel injector design for your car.
How can you tell if an injector is stuck?
When you’re at a stop sign or stuck in traffic, does your car splutter and shake? It’s not acting like a charging horse. It’s warning you that the fuel injectors might be soiled.
Even when the accelerator is down, “rough idling” is typically identified by variable revolutions per minute (RPMs). Engine stalling—a abrupt drop in RPMs and an audible noise that sounds like running out of gas on a hill—often occurs in conjunction with rough idling.
One of the engine issues that can cause rough idling and engine stalling is dirty fuel injectors. Come in for a Complete Vehicle Inspection if you detect any of these problems with your vehicle. If necessary, one of our skilled technicians will diagnose the issue and advise a fuel system cleaning.
Can you remove and clean the fuel injectors?
You also have the option of completely removing your fuel injectors and cleaning them on your own if the first approach wasn’t nearly effective enough.
- As previously, you must run your engine with the fuel pump unplugged in order to release the gasoline pressure. It’s best to use the technique recommended for your car because the procedure to remove the injectors will differ based on the make and model of the vehicle.
- Your fuel injectors may now be safely removed so that you can clean each one separately. You can apply your carburetor cleaner to the outside using a brush with soft bristles.
- To open the fuel injector, use a fuel injector jumper. Then, spray your cleaner through both sides of the fuel injector.
- After cleaning is complete, you can restart your engine and reconnect the fuel pump and injectors.
Are diesel injectors self-changeable?
It may appear difficult to replace a fuel injector, but with a little know-how, you can do it yourself and save a lot of money. Shops demand exorbitant prices for fuel injection work. If you are aware that your injector is defective, you can perform the repair at home.
What is the turnaround time for injector replacement?
It depends on a number of elements, including the make and model of your car, the extent of the injector damage, and the mechanic’s experience. In most circumstances, replacing a fuel injector shouldn’t take longer than two hours.
Bring your car to a dependable technician for a checkup if you’re having issues with the fuel injection system. They can tell you if you need to replace one or more of your injectors and can estimate how long the repair will take.
Should fuel injectors be replaced?
The lifeblood of a car is liquid fuel, either gasoline or diesel. You can go from point A to point B by burning this fuel, which powers the engine. As they perform exactly what their name implies, fuel injectors are a crucial component of the internal combustion process because they inject fuel into the combustion chamber. But do these essential parts ever need to be replaced? We conducted the research, saving you the time.
One billion cycles, or roughly the length of the vehicle, is the maximum lifespan for some gasoline injectors. However, given real-world driving’s challenging conditions and a lack of regular maintenance, the majority of fuel injectors may need to be changed every 50,000 to 100,000 miles.

Can I just swap out one fuel injector?
A single problematic injector can result in issues throughout the entire system. When it does malfunction in older vehicles, the others are likely to soon follow suit. Replacement of just one fuel injector will be ineffective and expensive unless additional issues are also in need of repair, which is typically the case.
If you have the money and the automobile is old, changing them all will help you avoid further issues. Simply identifying the cause of your problems and taking action there can save you money in the long term.
Waiting a while before making a replacement is preferable if you are short on cash because doing nothing now can prevent the need for another expensive repair later.
Before changing your injector, it is a good idea to run a diagnostic scan to rule out any other potential causes of the problem. It is advisable to replace just one injector rather than the entire system if you have a code for your defective injector. If the problem persists after this initial remedy, you might need to conduct additional troubleshooting.
