is this normal?

Thought as much, will the diagnostics as gizmo mentioned
Reveal the fault if any or would a thorough checkup at a bmw be a wiser choice

Honestly a "thorough checkup" at BMW was to run those same diagnostics on your car and see what codes come up, they don't have spare time. If there's nothing obvious, they'll simply clear adaptations on the EMS, and if the customer still comes back after that, replace air filter/fuel filter/spark plugs/coils/injectors/etc, until customer stops moaning or runs out of cash.

:roflol: this is so true...

If I recall my consumption on my E46 330i 6MT, I was getting about the same as you in town so does not sound too bad. But going the De-CAT route is a good idea with that millage...
Please do update the thread... Would be interesting to see the impact of the changes

on my 330 combined consumption was 10.5, then I replaced the diff with a 3.38 and it went to 12, then I did zaust and came down to 9.5.

So I would def remove those cats

ok.. I am very spirited driver in my e36 M3 and I get on average 10.5 to about 11 depending on how spirited I am but that also includes my long distance travels..
