Volvo 20814620 appears in public records with D12, D13 and D16 engine references, including Volvo truck applications. That is a wide engine range, so the engine family and old module label should stay together in the inquiry.
Check 20814620 on the original label. Then compare the plug, pins, lock, mounting holes and case depth. A D-series name by itself does not prove that every version uses this controller.
For a quote, send the engine model, vehicle or equipment details, ESN or serial information when available, and clear photos of the old ECU. Ask about software or programming status separately.
