Electronic Igniton on 240k

Got it in one (or two in this case).

You're right, no need to panic.

Just be aware that you could get caught with a real head scratcher if the charging system isn't spot-on or the battery starts to go on you.

The first symptom is usually the engine not firing while actually cranking over but trying to or actually firing as soon as you get off the starter. That's because the module isn't firing the coil while the voltage is right down. Then when the key goes from start to ignition the engine is still actually turning over and the module gets enough voltage to work and decides to fire the coil. Bloody frustrating until you suss it out.
