What we do
Will This Fix My Problem?
Honest answer: here's exactly what this service fixes — and what it doesn't.
Fixes:
- ✓New or used Mercedes module that will not work until it is SCN-coded
- ✓Independent shop that cannot do online SCN coding
- ✓Module replaced but the car still faults until coding
- ✓Need SCN coding without a dealer visit
Won't fix:
- ✗Faulty hardware that needs repair before it can be coded
- ✗FBS4 EIS/keys (dealer-only — not aftermarket)
- ✗Mechanical faults unrelated to module coding
- ✗Modules from a different make
The coding step most shops can't do
Plenty of shops can bolt in a Mercedes module but cannot complete the online SCN coding that actually makes it work, because it requires Mercedes online access. That is the gap we fill: send us the module you already have — new or used — and we SCN-code it to your VIN and verify it. If the module also needs unlocking, a VIN write, or a clone first, we handle that in the same job.
Shipping Instructions
These details are also emailed to you the moment your payment clears.
Ship your module to PO Box 120241, Arlington TX 76012 (USPS) or 1009 Oakwood Ln # 120241, Arlington TX 76012 (UPS/FedEx). Text or email your VIN and the module part number first so we confirm it is codeable and tell you if it needs any prep work beyond SCN. Return shipping is selected and paid at checkout.
What to include in your box
- The Mercedes module to be coded (new or used)
- VIN + the module part number
- For a clone, also include your original module
- A printed order confirmation
