Do BMW Injectors Need Coding?

The injectors must be calibrated, and it is required. Because each injector is unique, it would be less expensive if you wrote down the six numbers so the shop (or anybody you want) wouldn’t have to remove the engine cover to retrieve them. The piezo crystals inside it are the basis for the code.

Since each injector has a varied flow performance, the coding is necessary so the dme understands what each injector’s flow rating is. Specifically when your turbos are spooling up and in wot scenarios, this is to make sure you have enough fuel in the chamber. Your afrs shouldn’t be completely messed up.

That almost makes sense, however because fuel injectors might have varying degrees of resistance, they must all flow at the same rate in order to prevent varying cylinder combustions.

For each injector, the flow is the same for all 6 or 8 cylinders, whether it be 370cc, 550cc, or 750cc.

BMW is not the only company using direct injection; nonetheless, in my opinion, it has been overused.

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 detonation or significant ignition correction. If the problem is severe enough, it could result in a CEL, misfires, etc.

Next, attach the MX808 to the OBD2 port.

Although it’s a simple process, it deserves note. With the help of the provided OBD2 cable, connect the MX808 to the diagnostic port. When the scanner is turned on and plugged into the port, an audible beep will come from it. By doing so, it can be confirmed that the scan tool is speaking to the car and that the OBD2 port is powered. The car need to be in accessory mode (key on and engine not running).

How can I code the injectors in my BMW?

  • Step 1 is to swap out the injectors.
  • Second step: Connect the MX808 to the OBD2 port.
  • Third step: choose “Service”
  • Step 4: From the list of service menu options, choose “Injector.”
  • Pick a vehicle make in step five.
  • Read the vehicle VIN in step six.
  • Verify the vehicle information on the following table in step 7

Do you need to code your injectors?

Fuel injector coding is a necessary step in injector repairs. By correcting the injector’s code, you correctly balance the hydraulic parameters of the electromagnetic injector and, in the case of the Piezo Bosch, the piezoelectric injector.

When injectors are not coded, what happens?

An injector code is a code that is written to the ECU for precise communication and Injection volume control. It is frequently referred to as an IMA code (Bosch and Siemens) or a calibration code (Delphi). Vehicle makers are now required to more precisely control the fuel flow coming into the engine to maximize combustion efficiency and control emissions within permissible limits due to ever-increasing emissions legislation and tightening constraints.

Industry-standard IMA coding is Injector Menge Abgleichung (injector Quantity Offset). When an injector passes the OE test, it creates an IMA code that indicates where the needle and nozzle assembly fits within the tolerance range. This information is used by the ECU to adjust fueling and improve engine performance. Several problems can arise if the injectors are not coded:

  • Performance – In some systems, you might be able to start driving right away without noticing anything different. In actuality, if the injectors have not been programmed, the customer is not likely to be receiving the best performance out of the car and may even find themselves back at the shop with higher fuel usage, black smoke, etc.
  • Non-start – In more recent systems, the vehicle won’t start if the injectors aren’t coded.
  • Poor or lumpy running – Because the injectors are not coded, the ECU will continue to fuel as if the old injector were still in place, which can lead to subpar performance. Another trip to the mechanic is probably necessary if the engine management light comes on.

Do fuel injectors need to be coded?

Direct fuel injectors must be coded; each injector has a code that correlates to its precise spray pattern and flow rate during factory bench testing.

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.

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.

How much does coding fuel injectors cost?

Fuel injector replacement is absolutely not inexpensive. Depending on where you reside, what brand you wish to use, and where you place it, it will vary considerably. However, you should budget up to $350. The cost of the parts will be up to $200 at most, leaving the balance to cover labor costs and installation. Make sure the fuel injector replacement is done correctly. Always call a professional to replace a damaged injector because it will never be simple to do it yourself. Letting a professional do the task is still an excellent option, even if you want to save money. To make fuel injectors last a little bit longer, you may still learn how to clean them. Even better, you can go out and get a fuel injector cleaner. But why not use experts when it comes to replacements?

Does calibrating fuel injectors make sense?

The off-season is a fantastic opportunity to inspect the fuel injectors on any automobile, including the SpecRacer. The engine won’t produce its full horsepower or, in severe circumstances, the engine may be damaged if the fuel injectors don’t feed the same amount of fuel into each cylinder. The optimal stoichiometric mixture will not be present in all of the cylinders if one or more injectors are not delivering as much fuel as the others. The fuel mixture is adjusted by the engine’s computer based on the performance of each cylinder; if some are running rich, others are running lean. To ensure that all of the cylinders are operating at their maximum potential, it is crucial to have all of the fuel injectors matched. A lean mixture, pre-ignition, and subsequent engine damage can occur if one injector has much less flow than the others.

Can I replace the fuel injectors on my own?

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.

Following an injector change, should I reset the ECU?

Even though you don’t have to, it wouldn’t hurt to reset your ecu after installing the new injectors in order to erase any check engine light codes.
