My van kangaroos under load, the engine runs fine on tick over 7 will rev up no problem.
The scanner comes up with fault code P1687 an lists the fault as "Pump ECU not matched to ECU"

Welcome to the forum.

If this is relevant to your vehicle; try this:-

For Lucas DCN2 as fitted to DW8B engine in Partner vehicle, this code is geberated as a result of fuse number 2 in the engine fuse box being present. This is a hard fault code and will not clear. Remove the fuse from the engine fuse box (it should never be fitted), clear the fault codes. Disconnect and reconnect the battery, allowing the 3 minute rule etc.
Retest and read faults after connection.

Thanks

I have read this on some of the forums, would this be the same on the dispatch van though?

The van is a 53 plate & i have not had this problem before until recently.

Without full vehicle details; it's impossible to say.
