VW Comfort Control & Central Electronics Module (J519 / J393) Cloning & Key Programming — Mail-In Bench Service
Passat B6 or CC dead in the driveway after the footwell flooded — no crank, no central locking, and a used comfort module the car refuses? Mail us the original plus a matched donor and we clone the immobilizer, coding, and key data across on the bench, or program a key straight from the module for all-keys-lost.
Sending several modules? Add them all — one box, one return-shipping charge.

Will This Fix My Problem?
Honest answer: here's exactly what this service fixes — and what it doesn't.
Fixes:
- ✓Used comfort or central electronics module installed and the car cranks but will not start
- ✓All keys lost on a Passat B6 or CC, where the immobilizer lives in the comfort module
- ✓Water intrusion under the driver's footwell or through the plenum drains killed the module
- ✓Central locking, one-touch windows, interior lighting, or wipers dead or behaving randomly
- ✓No communication with the comfort or central electronics module on a scan tool
- ✓A second-hand module that needs to be made plug-and-play for your exact car
Won't fix:
- ✗Does not include the donor module — you source a matching used unit and we verify the part number first
- ✗Does not clone an original that is internally dead or will not read — that becomes a data-recovery job, see our ECU advanced recovery service
- ✗Does not cover cluster-based immobilizer systems on other VAG cars — see our VW/Audi cluster clone service
- ✗Does not remove or bypass the factory immobilizer — that is our separate VW/Audi immo delete and VIN programming service
- ✗Does not cover the newer VAG BCM2 architecture — see our VW/Audi BCM2 clone service
- ✗Does not repair the wiring, connectors, ground points, or water leak that killed the module in the first place
- ✗Does not bypass proof of ownership
Passat B6 and CC: the immobilizer is in the COMFORT module, not the cluster
On most VAG cars of this era the immobilizer lives in the instrument cluster, which is why our VW/Audi cluster clone service exists. The Passat B6 and CC are the exception: the comfort module carries immobilizer participation and key authorization, so all-keys-lost on those cars is a comfort-module job and the cluster service will not help you. It is also the platform where the module sits low enough to drown — blocked plenum drains push water into the driver's footwell, and the first symptoms are central locking and lighting faults, then a no-start. Clone it while it still reads. Proof of ownership is required.
Shipping Instructions
These details are also emailed to you the moment your payment clears.
Verify first: text or email us your VIN plus clear photos of your original module's label and the donor's label — a technician confirms the part numbers and hardware/software index are a compatible match, and confirms whether your car carries its immobilizer in the comfort module, before you ship. Then send both units for a clone, or the module alone for key programming, to PO Box 120241, Arlington TX 76012 if you ship USPS — or 1009 Oakwood Ln # 120241, Arlington TX 76012 if you ship UPS or FedEx (UPS and FedEx cannot deliver to a PO Box). We clone or program on the bench, test communication, and ship everything back via the return option you pick at checkout (Standard $24.95, UPS 2-Day $54.95, or UPS overnight $94.95).
What to include in your box
- Your original comfort or central electronics module (this is the clone path) AND the donor module
- Key-programming jobs: the module alone, plus any key or key blade a technician asks for
- Year, make, model, and engine (for example 2008 VW Passat B6 2.0T)
- VIN of the vehicle
- VW part number and hardware/software index off BOTH module labels — we pre-verify the match
- What is wrong now: water damage, no-crank, all keys lost, used module rejected, central locking dead
- Proof of ownership (title, registration, or bill of sale) — required for all immobilizer and key work
- Your name, return address, and a phone number or email we can reach you at
