Home › Module Programming
A replacement BMW control module — new or used — will not work until it is programmed with the right software, coded to the car’s options, and in many cases synchronized with the VIN and immobilizer. We do that on-site for owners and repair shops across San Diego County.
Three separate jobs usually get lumped together as “programming.” Knowing which one your car needs is what keeps a module swap from turning into a no-start.
Loads the correct software version onto the module for your exact vehicle and integration level.
Sets the module up for your car’s options and market, so every function it controls behaves as it did from the factory.
Matches security-related modules to the car’s VIN and immobilizer data so the engine starts and warnings clear.
These are the replacements we handle most often. If yours is not listed, text the part number and your VIN to 619-500-3096.
| Module | What It Controls | Typical Job |
|---|---|---|
| CAS / FEM / BDC | Keys, start authorization, body electronics | Used-module programming and synchronization |
| FRM | Lights, windows, mirrors | Replacement, programming, VIN coding |
| EPS | Electric power steering | Used-module programming to restore assist |
| Kombi | Instrument cluster | Programming and matching to the vehicle |
| EGS / ELV | Transmission, steering lock | Reset and synchronization |
| Headlight modules | LED / adaptive headlights | Programming and LED teach-in after replacement |
| Fuel pump control | Fuel delivery | Programming and coding of the replacement unit |
| Head unit | iDrive, navigation, CarPlay | Replacement and VIN matching |
Buying a used module? Match the part number and hardware version to your original before you buy, and keep the old module — its data is often needed to set up the replacement.
Text your 17-digit VIN and what the car is doing to 619-500-3096, or use the booking form.
You get exact pricing up front — mobile service within San Diego County included.
Home, office, or shop. A stable power supply is connected and the car’s current state is read and saved first.
The module is programmed, coded, and synchronized, faults are cleared, and every function it controls is tested.
In most cases, yes. Used CAS, FEM, EPS, cluster, and similar modules can be programmed and matched to your VIN, which is typically far less expensive than a new dealer-ordered unit. Compatibility depends on part number and hardware version.
Programming installs the module’s software. Coding configures that software for your car’s options. A replacement module usually needs both — feature coding on its own only changes settings.
Security-related modules such as CAS, FEM, DME, and EGS must be synchronized with each other. Until they are, the immobilizer blocks starting. That is a programming job, not a mechanical one.
We program, code, and synchronize modules, and handle the swap for common plug-in units. We do not do mechanical repair, so modules that require major disassembly should be fitted by your shop first.
Yes. We program modules on-site at independent shops and body shops throughout San Diego County — see shop and fleet services.
It depends on the module and what it needs. Send your VIN and the part number to 619-500-3096 for a flat quote before anything is scheduled.
SDBC handles coding, programming, diagnostics, and electrical/module faults. We don’t do mechanical repair or parts replacement such as brakes, suspension, or engine work.
Same-day appointments when the schedule allows — anywhere in San Diego County. Mon–Fri 9–6, Sat 9–2.
