My Mercedes E-class 2004 turns over but will not start. Battery is fine. It sounds as if it wants to start but doesnt! any ideas?

If you hear a mechanical hum then its either something with the starter or the battery. Charge your battery and see if its just a little too weak to turn the engine over. If that doesnt fix it, then you might have to replace the starter. Unless there is a serious mechanical issue, your engine shouldnt be the reason the starter can't get it to turn over.

If you take it to mercedes they will charge £3500 and will replace the gearbox, Alternatively you can change the shifter valve £25, new sump and filter as they have changed, fit a magnet inside the gearbox as the early A didnt have one. Fresh oil and see how you get on, the control unit for the gearbox sits inside the gearbox £1000 roughly for a new one but it has to come from mercedes in germany where it is coded to your chassis number, 2nd control units are not an option!!!!!!!

Check the ECM for Codes to help you find out what's causing  the problem. Here is a simple and easy way to check.
On board diagnostic (OBD) was designed on vehicles equipped with electronic fuel injection so you can generally retrieve the codes yourself. No need buying a scanner or running to any parts stores to check the Check Engine. This system is called obd1 and applies to most vehicles made before 1995 for domestics and 1993 on imports. In this article, I will discuss the methods used by domestic vehicle manufacturers on how to check the engine lights in their cars and Trucks.

For GM domestic vehicles made before 1995, the diagnostic connector is located under the dash panel by the driver side. To get the check Engine codes to flash in your dash panel, use a jumper wire or a paper clip and connect terminals A and B of the diagnostic connector. Turn your ignition key on with engine off and the codes should start to blink. All codes should start with code 12 which is one long flash followed by 2 short flashes. This code 12 means the diagnostic system is normal and will repeat itself continuously if there are no trouble codes. Otherwise, code 12 will flash 3 times before flashing the fault codes.

Counting the codes being flashed is easiest way to trouble shot problems in domestic vehicles and most of the codes can be erased or cleared by disconnecting the battery negative terminal for 1 minute and reconnect. Just make sure to check your service manual in case you have electronic equipment such as radio or clock that needs reprogramming in which battery disconnection is not recommended. Finally after performing repairs on the culprit code, always go for a road test to confirm if the problem is fixed.

Good luck and hope this helps

SOURCE: Engine won't start. Dash lights flash rapidly when key turned.

the battery says 12 volts but may be dropping to 4 or 5 under a load...i would suggest jumpstarting the car and see what happens.the battery should read in the high 12 volts and not less than 9.5 under cranking. the dash lights go out on your car when starting,and the alarm will go off ,and disable the ignition if the voltage is too low in cranking the car because the computer will shut it down and activate the anti theft.....check your battery posts are tight. best of luck
