Public records mention Volvo Penta diesel-engine applications for 20814594, including D9A and TAD1641, TAD941, TAD940, TAD1642 and TAD1643 references. Treat that list as a search lead. The original engine record still needs to match.
The old label should show 20814594 clearly. Photograph the controller where it was installed, then show the connector and mounting points. Cable direction and case shape can matter when an engine uses a similar-looking module.
When asking for a quote, include the Volvo Penta engine model, old label, connector photo, quantity and destination. Do not turn the public engine list into a guaranteed fitment statement.
Review other Volvo controller listings in the Volvo product range or search the product catalog using the original part number.
