Question 1

What accessory modules do you actually support?

Accepted Answer

Our coverage is broader than any single list can capture, but the quick answer is: if it's a programmable module on a late-model European, Asian, or domestic vehicle and it's not the main engine ECU, transmission controller, or ABS module, we probably support it. That includes adaptive cruise radars, HVAC/climate heads, park assist and 360 camera modules, driver/passenger door modules, memory seat modules, steering column and clockspring modules, sunroof and convertible top controllers, matrix/adaptive headlight modules, trailer brake modules, TPMS receivers, secondary gateways, and many more. Send us the VIN, year, and module part number if you have it - we'll confirm coverage before you commit.

Question 2

Can you actually remove VAG component protection at the bench?

Accepted Answer

Yes. We use a combination of OEM ODIS access, bench programming, and chip-data EEPROM work to remove component protection from modules in-hand. For modules still installed in the vehicle where original VIN data is accessible, online CP adaptation through ODIS is often faster. For donor modules already stripped of their original pairing, bench-level EEPROM work is the path. We pick the right approach based on the module and its current state.

Question 3

What's your success rate on salvage-yard donor modules?

Accepted Answer

For modules that physically power up, respond to bench-level reads, and haven't been damaged by water, voltage spikes, or prior bad programming attempts, our success rate is above 95%. The failures we see are almost always hardware problems masquerading as software problems - a module with internal flash corruption or a cracked solder joint will fail no matter how good the software side is. We'll tell you upfront if a module looks like a hardware casualty before we charge for programming work.

Question 4

How much does accessory module initialization cost?

Accepted Answer

We provide a fixed quote after VIN and scope review. Send the operation, VIN, and any DTCs and we return a number within the hour.

Question 5

Mobile DFW or mail-in - which one fits which modules?

Accepted Answer

Mobile DFW works best when the module is still installed in the vehicle and just needs coding, adaptation, or CP removal via the OBD port or directly on the bus. Mail-in is better when you have a loose donor module that needs bench programming before install - ship it to us, we program it to your VIN on the bench, and ship it back ready to plug in. ACC radars and adaptive headlight modules often start mail-in (for the software init) and then need a DFW mobile visit for mechanical calibration. Non-DFW customers can ship the module and then have a local ADAS shop finish the mechanical side.

Question 6

What happens if you can't remove component protection from my module?

Accepted Answer

If a module is genuinely stuck - corrupted EEPROM, damaged flash, cryptographic state we can't rebuild - we don't charge full programming rate. We charge a diagnostic fee for the time we invested and we'll tell you exactly why the module failed. In most of those cases the next step is sourcing a different donor module, which we can help you evaluate before you buy. We'd rather lose a billable hour than take your money for a module that's never going to work.

Question 7

How fast is turnaround on mail-in module work?

Accepted Answer

Once a module arrives at our Carrollton shop, typical turnaround is 24 to 72 hours depending on platform and queue. Simple VAG CP removals and BMW coding updates are often same-day. Rare modules that require hunting down OEM software versions or cross-referencing part numbers can run 3 to 5 business days. We confirm expected turnaround when we receive the module and log it in.

Question 8

Can you work on rare OEM modules from Ferrari, Bentley, Rolls-Royce, or McLaren?

Accepted Answer

Often, yes - especially when the underlying architecture is shared with a mainstream VAG, BMW, or Mercedes platform (Bentley and Rolls-Royce share significant architecture with VAG and BMW respectively). Truly bespoke exotic modules are a longer conversation - sometimes we can help, sometimes the OEM software access isn't available to the independent market. Send the VIN and module details and we'll give you an honest yes/no before anything ships.

Question 9

Do I need to bring the donor module and the car at the same time for DFW mobile service?

Accepted Answer

Not always. For most bench-level work we can pick up (or have shipped) the donor module, program it at the shop, and then dispatch the mobile van to your location for install and final adaptation. For jobs where the programming has to happen with the module connected to the actual vehicle bus, we schedule a single mobile visit and do everything in one appointment. We'll tell you which path your specific job needs when you call.

Question 10

What counts as an "accessory module" you can program?

Accepted Answer

Any body-network module that carries feature-enablement data or VIN linkage: remote start controllers, heated/cooled seat modules, trailer brake control modules, power running board controllers, trailer camera modules, roof-panel controllers, and similar convenience electronics.

Question 11

Can you activate a factory-installed feature that the dealer never turned on?

Accepted Answer

Often yes. Many OEM modules ship with all features in the firmware but only some enabled by option bytes set at the dealer. If the hardware is present, we can frequently enable the feature in software without adding new parts.

Question 12

I bought a used module from a salvage yard. Can you reprogram it to my VIN?

Accepted Answer

Yes for most platforms. We overwrite the donor VIN and re-provision the module to your vehicle's configuration. Some late-model modules use rolling security tokens that prevent used-unit transfers - we confirm feasibility before you buy the donor.

Question 13

Do you need the whole vehicle or just the module?

Accepted Answer

Mail-in accessory-module service is available nationwide after review. For option-byte writes that require live vehicle parameters, we may need the vehicle on-site in DFW; support confirms the correct path during quoting.
