I have a 2007 E65 750i and I replaced the DMTL pump TWICE but I am still getting the error code. When I reset the code it comes back on immediately. I have done / Checked the following work listed:

New gas cap
new valve stem seals - all 32
2 new / different DMTL pumps
New vacuum lines up front in the engine compartment
Checked the ground and wires for the DMTL pump - good
Checked fuses - all good
New alternator bracket oil seal - not that this would have any effect
New valve cover seals and gaskets
New crank case vacuum lines and pcv diaphragm

With the engine running I have removed the oil fill cap and there is good vacuum. The car runs and drives like a champ and it has 165k on it.
I am at my wits with this car, any help would be appreciated.

An update to this problem.

I have replaced the IVM (Integrated Supply Module) computer. No change the error code is still present.
