As I am researching N249 deletes to try to check what solution a previous owner has put in place I found the following site which has a reasonable description of what it does and a useful schematic:

I seem to have a slightly messy DV to T piece pipe, then T piece to inlet manifold and then to other larger T piece branch going off to a bolt capped hose - sense this could be done better. Then the N249 is still in place but with a small hose providing a direct closed loop back into the valve but the hose connector on the other side with no plug - is this a valid set up? The vacuum reservoir has been removed.
Am now pondering whether to reinstate the system as it should be, whether it makes sense to and whether I can if I can get a vacuum resevoir- opinions seem to vary as to whether it is good or bad to have the N249.
