Attached is a quote for a PCU with the programming for your engines. However, I need to know which version of EVC you have.
In the quote, I assumed you had an EVC-C3, but you need to look on the actual box which will tell you which one you have (you could have a EVC-E, EVC-C2 or a EVC-D).
The serial numbers you provided do come back as D4-300A-A, but Volvo Penta does not keep very good records on which EVC you have. I can contact them and they will give me what they think is your EVC version, but I would much rather you physically check.
The price of the PCU and the programming does not change depending upon which EVC you have, but the part number does change.
