Welcome to the BMW Check Engine Light codes page. Below you will find the most complete list of BMW trouble codes available. The code definitions are a good starting point when determining the cause of the service engine light but where do you go from there? We have a large number of resources to help you repair the problem. Here is how we suggest you proceed. Look up your code definition. This tells you where to start testing. If you are unsure of any abbreviations, check out the acronym list by clicking on the link at the left. Next, read our article Automotive Circuit Testing, and if there is an article related to the system you are testing, such as Oxygen Sensors or EGR concerns, read these as well. They will provide valuable info! If there is a link to a specific diagnosis strategy for the code then follow that and start testing.
If there is no procedure for your manufacturer specific code, then I suggest referring to a similar generic OBD II code (these are listed numerically by system type) to get a good idea of what to look for. If at this point you still need assistance use the 'Get Help' link and let us know how we can help. We can provide information on component location, specifications, circuit color/location and more. We do ask that you please read the info available on the site first so that we can help reduce repeat questions. So please read our Disclaimer and when you're ready jump in!When fuel consumption grows, most probably, the rough run of the engine has also started. If MSD80 has registered following error messages (one or few of them. F10 / F11 Model Year: 2010-2016 Model Year: 2004 - 2009 Chassis Code: E60 Body Type: Sedan / Wagon / M5 Model Year: 1995 - 2003 Chassis Code: E39 Body Type: Sedan / Wagon / M5 6; 7. BMW MSD80 Fuel Injector Fault Code Diagnosis - 30BA 30BB BMW models with Turbocharged N54 engines and MSD80 DME Software can develop fuel injector MOSFET driver failure. This will cause an injector to stop delivering fuel and an engine misfire to occur.
Also, we value your feedback and like to hear stories of unusual fixes or concerns you may have run into with your Check Engine Light, so feel free to share your experiences by using the 'Contact Us' link. Let's go!
We do our best to update these BMW check engine light codes as frequently as possible. If you find one missing let us know and we we'll add it immediately! Please use the form on our Contact Page to get in touch with us. We certainly understand how frustrating it can be to look for a code definition and have it not online when you need it. And lets face it, if the service engine light is on then you need it now! It's easiest to use the 'Find On This Page' feature of your browser's 'Edit' menu to find codes on this page as the list is quite long. These are listed in numerical order for easy searching.
When retrieving BMW check engine light codes with an OBD II scan tool, proceed as follows:
1. Connect scan tool to the 16-pin data link connector (DLC) located underneath the steering column. The connector may have a removable cover.
2. Turn the ignition on.
3. Follow scan tool manufacturer's operating instructions to access the Diagnostic Trouble Codes (DTC's).
Remember, these are manufacturer specific codes only. Refer to our Generic OBD II code list for definitions on all other BMW diagnostic trouble codes.

Mileage: 128,554
Bmw Fault Codes List
Problem: The vehicle owner asked the shop to replace the coolant and thermostat using the aftermarket part he provided. The technician installed the thermostat and replaced the coolant, but after the job was completed, the engine became hard to start and the malfunction indicator light (MIL) came on.
Details: When the technician connected the scan tool, he retrieved the following diagnostic trouble codes (DTCs):
- 2B5C – P0335 – DME2: Crankshaft Sensor signal
- 2D0F – P0100 – DME2: Air-mass Sensor, Bank 2 signal
- 2EF5 – P0598 – DME: Map Thermostat activation
- 2A80 – P2088 – DME2: Inlet VANOS Bank 2 activation
- 2A85 – P2090 – DME2: Exhaust VANOS Bank 2 activation
- 2D14 – P113B – 2D14 Engine Electronics Air-mass Sensor Correction Signal
The technician rechecked all his work and everything seemed to be fine. He called ALLDATA Tech-Assist for advice. The Tech-Assist consultant told the technician that there had been many reports of problems using aftermarket thermostats on these vehicles, which included hard starting, extended engine cranking times, and blown fuses.
The consultant suggested disconnecting the thermostat electrical connector, clearing the DTCs and see which DTCs reset or change. He also advised to verify that fuse 006 in the integrated supply module, located at the right rear of the engine compartment, was okay.
The technician checked fuse 006 and it was open. He installed another fuse and it popped immediately. When he connected the old thermostat, the fuse did not pop.
Confirmed Repair: The tech ordered a new thermostat from BMW and installed it. As it turned out, the aftermarket thermostat was causing the multiple DTCs, the hard start and fuse 006 to blow. After the repairs, the engine started and ran normally, fuse 006 was fine, the DTCs were cleared and they did not return. Fixed!
