"X" = MY2000/2001 = ME7 engine management = No dump valve.

Im confused,
A recirc valve bleeds surplass charged air.
Does that not make it a dump valve, albeit to the inlet air pipe rather than, as i expect you are referring to, atmosphere?
Can we move this from the Register section?

A recirculation valve recirculates the charged air back into the air intake system which has been metered from the MAF.

A dump (Chav)valve dumps the charged air to atmosphere (as you have stated)thus confusing the metered air which in turn will make the engine run rich..

Agreed on the technical side but that does not show the recirculation valve not to be a dump valve, in a technical sense.
