Hi there, its actually in the engine bay at the back behind the auxillary jump start battery terminal.
The 1995 328i has the 'M52' engine and has a timing chain.
A 1997 BMW 328i uses standard 10w-30 engine oil. This provides a good balance of protection and heat dissipation for the engine.
the 328i BMW if it is the M52 engine should be using 5w30 synthetic oil, same as the 2.8 Z3
its the fuel pressure regulator control unit fault usually low fuel pressure
2796 cc
at the right of the engine just under the air filter
In the coolant reservoir in front of the engine.
Can not be repaired, only replaced with the thermostat housing as one unit.
on my 328i I had that problem, and found that the tube that held the oil dipstick was sucking air at it's base where it meets the engine.
Mobil one 10w-30
inside the engine compartment and on the fire wall
Im trying to swap the starter on a 1999 BMW 328i
