TOO MUCH ENGINE BRAKING AND EXCESSIVE FUEL CONSUMPTION

2005 BMW 316 • 25,000 miles

I have an old(2005) and low performance bmw 316 at its 40 000 km (its been in garage for some time after it's done 19 000, then I bought it, so everything rubbery is problematic if that will help), I feel like it burns more fuel then it should considering its performance, since its almost 20 sec. From. Naught to 60 : D, it has a more noticeable engine braking compared to my 2005 passat 1.6 (almost twice as effective), and a higher fuel consumption, when I stop the engine when idling, the rpm needle (or whatever it is, not a native speaker) drops to 0 immediately like in a millisecond or so. No inertia no nothing, oil and everything is regularly checked up but I think there is something deeper going on. Do you have any ideas what could the problem be?

Very possible that the crankcase vent valve will require replacement
