Volvo REM Cloning & Data Transfer — Mail-In Bench Rear Electronic Module Service
Rear lights acting up, fuel pump dropping out, or the REM throwing comm faults after water got in the back? Mail in your original plus a matched donor and we clone the config and coding onto the replacement on the bench so it drops in.
Sending several modules? Add them all — one box, one return-shipping charge.

Common reasons
Will This Fix My Problem?
Honest answer: here's exactly what this service fixes — and what it doesn't.
Fixes:
- ✓Rear lighting faults after a REM failure
- ✓Loss of fuel-pump control / no-run traced to the REM
- ✓REM communication faults or U-codes after a rear fault
- ✓Water intrusion in the rear corroded the REM
- ✓You installed a used donor REM and it won't match or communicate
- ✓You want your REM's config and coding carried onto healthy used hardware
Won't fix:
- ✗Does not include the donor REM — you source a part-number-matched used unit (we verify the numbers first)
- ✗Does not clone a completely dead or unreadable original — that REM cannot be read
- ✗Does not do an on-car dealer programming session — this is bench data transfer
- ✗Does not repair burnt or corroded rear harness, grounds, or connectors
- ✗Does not repair a mechanically failed fuel pump or rear lighting hardware
- ✗Does not fix faults caused by wiring, blown fuses, or bad grounds
- ✗Does not program a REM that a technician cannot confirm as supported by VIN
A used REM won't just drop in — it has to match
The REM is coded to the car it came from, so a junkyard rear module bolted in will typically throw communication and configuration faults instead of running the rear lights and fuel pump. Cloning your original REM's config and coding onto that donor makes it match your vehicle so it drops in and communicates. The donor must match your part number, a completely dead or unreadable original cannot be cloned, and this is bench data transfer — not an on-car dealer session, and not a repair of corroded rear harness or connectors. A technician verifies the donor and your REM by VIN and module label before you ship.
Shipping Instructions
These details are also emailed to you the moment your payment clears.
Verify first: text or email us your VIN and REM part number off the module label and we confirm your platform and the donor match before you ship anything. Once verified, remove the REM (and the donor, if cloning) and ship it 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 the data on the bench, test communication, and ship it 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 REM AND the part-number-matched donor REM (if cloning)
- Year, make, model, and engine (e.g. 2012 Volvo XC70 3.2L)
- VIN of the vehicle
- REM part number off both case labels — we pre-verify the match
- What is wrong now: rear lighting faults, fuel-pump control loss, no-comms, or a used-REM mismatch
- Whether the original still powers up and communicates
- Whether you are cloning or having a used REM matched to the car
- A clear photo of the REM part-number label, plus your name, return address, and phone
