The Volvo Trucks VNL VNL 670 12.8L I6 ECU is a crucial part of your vehicle’s engine management system. Our ECU cloning service ensures optimal performance by replicating data from your old ECU to a new donor ECU, maintaining your vehicle’s reliability and functionality.
Common Issues with ECUs:
ECUs can encounter several problems that necessitate cloning, often due to damage. Common reasons for ECU replacement include:
● Flooding
● Burning
● Hardware failure
When the original ECU is faulty, customers typically purchase a donor ECU with the same part number. Our cloning service transfers the original data, including VIN, keys, and coding, to the donor ECU, enabling your vehicle to start and function properly.
How the Cloning Process Works:
1. Add to Cart and Payment: Select the Volvo Trucks VNL VNL 670 12.8L I6 ECU cloning service on our website and add it to your cart. Proceed with the payment to complete your order.
2. Prepare Your ECUs: Mark the original ECU as “old” and the donor ECU as “new.” Ensure both ECUs are securely packaged for shipping.
3. Shipping: Print your order receipt and include it in the package. Ship both the original and donor ECUs to Karmanauto.
4. Cloning Process: Upon receiving your ECUs, we will read all necessary data from the original ECU. The data will then be programmed onto the donor ECU, making it an exact replica.
5. Verification and Shipping Back: We will verify that the cloned ECU received the original data. Both the original and cloned ECUs, along with a receipt, will be shipped back to you.
Why Choose Our Service?
● Reliable: Ensures your vehicle’s ECU is accurately cloned.
● Experienced: Expert technicians with extensive experience.

About this service
Volvo Trucks VNL 670 ECU clone and programming service. Coverage verified by ECU part number.
Karman Auto bench-clones the data from your original ECU — including VIN, mileage, key/IMMO data, and configuration — onto your replacement unit. Compatibility varies by module part number, so we verify the part number before programming.
Mail-in process
Mail your original ECU module along with a matching donor/replacement module to our shop. We clone the data on the bench and return the cloned unit via USPS Priority. Average turnaround is 24 hours from when both modules arrive. Include your VIN, mileage at extraction, and a working key if available. All work is warranty-backed.
FAQ
Q: Can you clone my Volvo Trucks ECU?
A: Most Volvo Trucks ECU part numbers are supported. We verify compatibility by reading the part number from your module at intake. If your part number isn’t supported, we’ll contact you before charging.
Q: Do I need to send both the original and donor modules?
A: Yes. We clone FROM your original module TO your donor/replacement. The donor module should match the original by part number for plug-and-play results after install.
Q: How do you verify compatibility?
A: We read the part number directly from your module and cross-reference our cloning database before any programming begins. You’ll be notified at intake if there’s a compatibility issue.

What causes Volvo Trucks VNL 670 12.8L I6 ECU module failure
Volvo Trucks VNL 670 (US-market North American truck) is built at New River Valley Assembly (Dublin, Virginia) on the VN platform. The D13 12.8L I6 in VNL 670 sleeper cab is configured for long-haul applications with specific EECU calibration for fuel economy + AdBlue/DEF emissions. Common failures: water intrusion from cab seal degradation on older VNL trucks; internal capacitor aging on 2013-2017 first-batch EECUs; AdBlue dosing pump faults cascade to EECU; over-the-road vibration over high mileage causes solder joint fatigue. Other: jump-start over-voltage from 24V system spikes.
Volvo Trucks VNL 670 12.8L I6 ECU clone — frequently asked questions
Can you clone a Volvo Trucks VNL 670 12.8L I6 ECU?
Yes. Karman Auto clones every Volvo VNL 670 EECU across D13 410hp, 425hp, 455hp, and 500hp output variants for VNL Series 4 and Series 5. 27 years of heavy-truck bench expertise since 1999.
Does the VNL 670 EECU clone preserve fuel economy maps?
Yes. The EECU stores fuel maps, injection timing, AdBlue dosing logic, and torque curves. Clone preserves all calibration data byte-for-byte — VNL 670 long-haul fuel economy stays exactly the same after install.
Will the VNL 670 I-Shift transmission work after EECU clone?
Yes. I-Shift TCU handshakes with EECU. Clone preserves the pairing exactly.
How long does the VNL 670 EECU clone take?
24-48 hour bench turnaround from when we receive both modules. USPS Priority shipping back same day.
What fault codes indicate a failed VNL 670 EECU?
EECU-001A, EECU-9300, EECU-A100. Driver display “Service Required”, engine derate warnings, AdBlue system warnings.
Will the AdBlue/DEF dosing work after the VNL EECU clone?
Yes. AdBlue/DEF dosing logic is in the EECU calibration. Clone preserves it exactly. If DEF warning persists after install, the dosing pump itself may need separate replacement.
Will VNL 670 sleeper APU interaction work after EECU clone?
Yes. APU (Auxiliary Power Unit for sleeper cab climate control) integration with main EECU is preserved in the clone.
Do I need a donor with exact same VNL 670 part number?
Yes. Part numbers vary by emissions tier (EPA 2013 vs EPA 2017+), gearbox option (I-Shift / manual), and HP rating. Verify the white sticker.
Will my VNL fuel economy and accumulated mileage continue to track?
Yes. All counters are preserved in the clone byte-for-byte. No reset to zero.
Can you clone a water-damaged VNL 670 EECU?
Yes. EEPROM recovery at chip level even on bricked modules. 27 years of bench-level chip work.
Does the EECU clone affect Volvo Dynafleet telematics?
No. Dynafleet handshakes via VIN which we preserve exactly.
Will the driver display need re-pairing after EECU clone?
No. DIM-EECU pairing data is preserved.
Will my VNL 670 cruise control work after the clone?
Yes. Cruise control authorization is paired to the EECU via vehicle CAN. Clone preserves it exactly.
Is Volvo Trucks VNL 670 EECU cloning legal?
Yes. Module cloning for repair is fully legal in all 50 states.
Why choose Karman Auto over a Volvo Trucks dealer for VNL 670 EECU?
