hyjacker and oP both./ no year told, wow. no country told in the USA we have EVAP 3, systems test s that even run as we sleep.! but does not repeat, key off. 1 time yes. key off. or delayed as the PCM waits for fuel to cool off. (tank pressure tests it does,by law here USA) if really curios find the source of the noise under hood, under dash, under at gas tank(evap parts) use long cardboard tub to an ear and find it. this is not hard to do. find the source first then ask why it makes noise. and get real answers, 3000 parts on car gee. or pull fuses when it makes noise. you didnt say aftermarket ALARMS with shake switch horror ! or other wild car hacks , remote starter man killler. key off , noise is very small list of things key off . we are deaf here so all I can say is learn to find noise even making home made tools or a $5 mech stethoscope. (I have and electronics one with 4 microphones your noise is easy find,car parked, be happy it does not happen only moving car, those can be dangerous to find, lacking my tools or ask tech to find the noise. what else is there?, nada got other hacks, like REMOTE START BOX> we can't guess why any car or machine makes noise!!! ever. only how to do the tests. what stops you, IDK.

Fuses shouldn't keep blowing and that was the cue to get it looked at. You either need to get it towed to the dealership, or contact a mobile auto-electrician with a pro grade scan tool computer to diagnose the electronics. This is not the type of issue you can fix yourself unless you spend $3.5k to $5k on a bi-directional scanner.

Negative, like every other modern vehicle. It's only some old classics from before the late 1960's which use positive grounding.

a 1997 roadster does not have a drive belt it has a chain and i have never heard of anyone needing to replace it at any mileage

as you've had the OBD scanned i'd go with getting the codes erased, after noting down what they were, and see if problem persists, if does then change whatever the codes indicate

German cars are weird. Changing a battery can disable many things. It will have to be reset by computer. Don't be surprised if you have to go to the stealer dealer for that.

fan electronics start at the sensor in the cooling system, and sends a signal to the ECM which in turn closes a relay and turns on the fan/s There are 2 fuses in the system. one for the power to the sensor and one for the power through the relay I suggest an accredited auto electrician with experience on your vehicle to quickly find the problem point.

The EGR valve opens when the engine is warming up, which allows exhaust to enter the intake manifold. This is essentially "extra air" coming into the engine. The engine has an "idle speed control" function, which is either a solenoid or small stepper motor connected to a valve that allows a controlled amount of air to "sneak" by the throttle plate in the throttle body. Fundamentally, it is the amount of air entering a fuel injected engine that controls engine RPM. A defective idle speed control ("ISC) motor or solenoid can cause the problem you stated. (I do not know which type is used in your BMW.) Often, a check engine light will illuminate of the engine computer cannot adequately regualte engine idle speed.

Change thermostat since you change coolant. Also did you fluch radiator and clean the fins on radiator? Make sure new fan clutch works and also that you have proper pressure cap on radiator

for P0740 it is: OBD-2 P0740 - Torque Converter Clutch Circuit/Open OBD 2 net TCC malfunciton P0740 OBD II Code

One of 2 things. The part on the end of the starter called a bendix is bad (most likely and less expensive) or the ring gear that the bendix engages is bad. (less likely MORE expensive). If you are comfortable with the work try locating a starter locally and replace it yourself.

1st check fuse to fuel pump, and fuse to fuel pump relay. You might want to have a look here in Bimmer Forums Thread Z3 Won start Fuel pump Relay problems If they are OK, you'll need to be sure no wiring on this age 17 car still good (I have a '97 328i convertible, fun to drive, but what went wrong *this* week) So check for voltage *at* the fuel pump, it won't run w/o power. If that's ok, then you are down to either a bad fuel pump, or blockage in fuel line, probably at filter. (a) See if pump is actually pumping fuel out. (( FIRST, listen, and see if you hear motor running )) (b) Since you may now already have fuel line disconnected at pump end, disconnect other end, and use bicycle pump, or some other source of pressurized air and see if the line is clear. In *any* event, I'd change the fuel filter.

REPLACE YOUR SEAT RAIL BUSHING

If you just got gas, check your gas cap is closed tightly. If it isn't it can't pressurize correctly.
