W108 Starter motor sticking a bit
Ah jeeze, been making a lot of threads lately. Guess I should just make a combined one at some point. Anyways,
We just returned the 280 SE from winter storage. Started up with no trouble, other than a bit of a lumpy idle when cold, as the CSV unit is leaking. Anyways nothing unusual. We drive about 200 meters until we get to the petrol station, shut it off, fill it up, add the additive and start it up again.
However the starter motor was playing games and decided to stick on with the engine spooling up. This obviously made a weird noise and made the idle screw around, so we shut it off within 5 seconds. Then we gave it a short 10 second rest and fired it up again with no trouble. Guess we've started it up about 4-5 times no with absolutely no trouble.
Was the solenoid just sticking a bit because of the car not being used for 5½ months (it had been fired up every now and then, but only short to be moved around in the winter storage)? I'm willing to pay for a new starter motor, however if it's just a one-off situation, then I'm not too frightened.
EDIT: Read a bit about the starter motor in my service manual, seems like it has a freewheel to stop the starter motor from going up to the high RPM's together with the engine. Is this true? Would give me a bit more confidence in the car, if I knew even if it did stuck on for a couple seconds, it wouldn't damage the flywheel (a lot). Obviously going to get a new starter if it's getting occurrent. Also worth pointing out that the starter motor did turn off when the engine was turned off too, so it wasn't the power to the starter motor going bonkers. Just seems like it stuck a bit.
