Dear Customer,

Thank you very much for the detailed information.

In principle, the vehicle can be started by external starting, which means that the starter motor is intact.

You also write that your battery has a charge of 12.5 volts, so it should be OK.

Because of the constant short journeys, the problem could be with the battery or the alternator.

A battery is charged by the alternator while driving, but if the alternator does not have time to charge the battery (only 5 minutes of driving), there will be
a.) a cell short circuit - battery
b.) a defective alternator - carbon pins worn out.

You would NOT notice a battery cell short circuit by the voltage, but only if you switch on the ignition and gradually switch on the consumers, such as lights, radio, heating, air conditioning, and then look at how far the voltage drops.

A defective alternator can be recognised by the fact that the battery is no longer being charged correctly or that the starter motor turns very slowly, even though the battery is intact.

So I would consider both, check and replace if necessary.

If you have any further questions, please do not hesitate to contact me.
