Hello everyone, I have a question regarding the following to engine management codes; P025218 and P025219 both mention the quantity control valve but I am at a loss, no clue what the quantity control valve is. So any help would be appreciated. Thanks

It's related to the fuel rail pressure isn't it? - The quantity control valve is between the low pressure (tank) pump and the high pressure (rail?) pump.
I don't know, but suspect that it's integrated in the high pressure pump, in which case it might only come with a new high pressure pump. - Before you fork out for that, check it's not a blockage in the filter.
