Do BMW injectors require coding?
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.
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.
Where can I locate my injector code?
Diesel injectors were once thought to as plug-and-play devices. The garage is unable to determine if an injector requires coding or not due to the introduction of more sophisticated systems (Common Rail injectors).
In comparison to conventional diesel systems, common rail diesel systems have a number of benefits, including improved performance, reduced fuel consumption, and quieter engine flow. The possibility of the Common Rail System to significantly reduce emissions, which is the buzzword on the lips of every eurocrat, is another important benefit of the system.
Why then use the injector code? The injector code is a code that is programmed on the ECU for precise communication and injection control. It is commonly referred to as the IMA code (Bosch and Siemens) or the calibration code (Delphi). Vehicle manufacturers have been compelled to more precisely manage the flow of fuel entering the engine in order to maximize the efficiency of the combustion process and regulate emissions within permissible limits as a result of the ever-increasing emission legislation and tightening of limitations.
Industry standard IMA (Injector Menge Abgleichung / Injector Quantity Offset) coding is used. When an injector passes the original equipment test, it outputs an IMA code that indicates where the needle and nozzle assembly is adjusted within the tolerance range. This information enables the ECU to adjust fuel properly and improve engine performance. Several issues can arise if the injectors are not encoded:
Performance – You might be able to drive on some systems without seeing any differences. In reality, it is doubtful that the client would attain optimum vehicle performance if the injectors have not been coded. After some time, mistakes can happen.
No start – In more recent systems, the car won’t start if you don’t enter the injector codes.
Low performance or inconsistent engine operation could result from the injectors not being coded, in which case the ECU would continue dosing as if the old injector were still in place.
Common Rail Injectors from DELPHI – Always need engine coding. 16 alphanumeric characters (for C2i injectors) or 20 characters (for newer applications) constitute a typical code (C3i injectors). The injector head is typically where the code is located.
The majority of DENSO Common Rail injectors require coding, while some very early models might not. Depending on the manufacturer of the car, a typical code length is 16–24 alphanumeric characters. The injector connector is often where the code is located. For this information, you can also scan the QR code on the injector.
VDO/Siemens Common Rail Injectors – At the moment, only VW applications need coding. The injector head is where you’ll find the normal length of six digits.
The majority of BOSCH Common Rail Injectors require coding, while some earlier models might not. Simply put, the injector needs coding if the IMA code is present. The injector connector head is where you’ll find the code, which is typically 6 to 10 digits long.
Note that the information about coding above pertains to brand-new diesel injectors. If an authorized service expert sells you a remanufactured injector, it will also come with a new calibration code, which is often applied to the injector as a sticker or label. The generated test report also contains this code.
The Sales Records Act mandates that the seller give the purchaser a receipt. In the event of a technical issue, he must register the received revenue with the tax administrator online within 48 hours at the latest.
Does the fuel injector have a code?
P0171 and P0174 fault codes, which show the engine controller is sensing a lean state, are the most frequently seen fault codes linked to clogged fuel injectors. If the injector leaks or is not atomizing properly, fault codes for a rich situation may also be seen.
Do you require new injectors to be coded?
To make new fuel injectors function properly with your car after switching to them, you must code the new injectors. FORScan can be used to accomplish this.
SY Diagnostics prepared a video guide that outlines the procedure. View it in the video down below.
To make it simpler to alter and comply with the ever-tighter emission requirements implemented since 2010, manufacturers have put injector coding into injectors. When installing new injectors, you must program them so that the ECU receives the proper signals to execute the calculations necessary for the engine to operate at its best efficiency while using the new injectors.
The IMA coding (Injector Menge Abgleichung) from Bosch and Siemens is the accepted injector code in the industry. Depending on the type of vehicle, the codes normally contain 6 to 24 alphanumeric characters. If the proper code is not used, the engine will perform inefficiently, not start, or run poorly or unevenly.
We would like to express our gratitude to SY Diagnostics for creating this fantastic film. More of their videos may be seen here.
You’ll need a dependable OBD2 tool to use FORScan to apply fuel injector code. The OBD2 devices we recommend that operate perfectly with FORScan are listed below.
Note: The OBD2 USB adapter is recommended for FORScan coding adjustments as it offers a more reliable connection.
If I don’t code my injectors, 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.
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?
What is a scan tool for injector coding?
To read injector compensation codes, inject live data, and program new injector codes to the ECU for precise communication and injection management, employ injector coding scan tools. Each cylinder’s injector code needs to be verified or updated after the ECU or injector is replaced so that the cylinder can more precisely identify injectors and control fuel injection.
Our Injector Coding Scan Tools include a wide range of built-in features, functionality, and vehicle coverage options. From single-brand OBD scanners to comprehensive, bi-directional workshop scan equipment for every system.
With Delphi, are injectors possible?
- Small variations between injectors due to machine tolerances may affect fuel delivery. Engine performance may be reduced by changes in timing and flow.
- Each injector’s performance is tailored using precise Trim Codes to meet the best requirements.
- Delphi Remanufactured injectors come with a special trim code that can be found on a CD-ROM disc and is used to customize each injector’s output.
- In order to ensure proper engine performance, the new unique trim code provided must be entered into the engine ECM using the Delphi Trim Code Software.
Is 1.4 TDCI injector coding required?
When the injectors are changed, coding is required. The old ones would also need to be recoded if they had been reinserted but in the wrong order. Typically, the only issue with these is one or two injector failures.
