i have a l reg golf van , the engine let go the other day after a meer 200.000 miles
anyways my friend has sorted me out with a turbo engine, it was a plane old NA 1.9 di but this new engine is out of a polish seat. there is a little valve bolted to the bulkhead that is in a pipe that goes somwhere on the turbo to the vacume hose on the brake servo. there are two little wires that disapear into the loom, one black and the other black with a yellow tracer, what is this dooby and do i need it?? i have done some searching and i think that i have got an AAZ engine? any help is a great. thanks Adam.
