some vehicles will reset to computer if you leave the battery disconnected for a while (sometimes 15-30min)
Disconnect the battery for 5 minutes get the radio code before doing this
It is doing a guage check. Most big trucks and diesels do it. Not seen it in a gasoline engine though.
disconnect the battery cables for 5 minutes then reconnect them. remember to reset the clock after doing this.
No, because you need a battery to run your car. Doing so can ruin the alternator.
On 200 + 300 tdi Yes just disconnect the battery. when you put battery back on before using it just make sure you check the engine oil level.
If it is a continues clicking sound you here it is probably the starter solenoid. This does not mean the solenoid is defective, it means either the battery is low on charge or you have a bad connection from the battery to the starter. Turn the headlights "on" and try to start the engine. If the lights are bright when you are doing this, you probably have a bad connection. If the lights are dim when you turn them "on", check the connections to the battery, if the connections are good, the battery is low on charge. Next, check your battery and charging system.
Repairing the fault which is causing the check engine light is the recommended way to go about doing this.
Check your Battery by doing a load test. If it passes a load test, you should check the starter to see how many amps it is drawing! Ranges vary on a battery load test depending on temperature. Usually if it goes below 9.6 volts at a room temp. or a bit colder, the battery has failed. I think a good starter should draw approximately 250 - 300 Amps.
Charge or replace the battery, put some fresh gasoline in the tank and check fluid levels. Crank engine over with the key in ten second intervals pausing briefly to pump the gas peddle to prime engine. After doing this for three to four times the engine should start and run.
No, a deep cycle battery is designed to be run completely down without doing harm to the battery. A normal automotive battery be it diesel or gasoline is not designed to be run flat and every time it is run flat it's life is shortened.
Not a good sign, This could mean that your charging system (alternator) isn't doing its job. If you have problems starting the car due to not enough battery power, then check your battery to see if it is holding the charge. If after a while that you had to boost or jumpstart your battery your car gradually dies then check your alternator to see if it is putting out charge to the battery.
check wiring also check engine see if its locked up do this buy putting car in neutral put e brake on place a socket on crank nut and turn it see if engine rotates before doing this make shure coil wire is disconnected if engine turns you have probaly bad starter selonoid
