Have you checked what the fuel mixture is doing? Sounds like it is running on the rich side

Looks like they are all running a bit rich.......
My `89 745 turbo was the same 23mpg whatever i did!
Mercedes C320CDI Sport Estate 3 litre V6 7 Gear Auto
Remap 290bhp 628Nm torque @ 1600revs 45.1mpg
You need a 940. My 98 2.3 lpt and 95 2.3 lpt with 15g both do over 30 mpg driven gently and I have seen over 35mpg when in full grandad mode.
However the one with the 15g doesn't get driven slowly as often

Its not that hard to update to the 940 engine management but if you are going to the effort then a megasquirt conversion would be the way to go
T5Frankie Go estate 940 and put a 740 front end on
I had a lovely lowered silver GLE saloon about 15 years ago. Lovely car but thin rods and older is not worth the hassle - or the fuel bill!!!!! Unless your 740 is just a toy and fuel doesn't matter.
