Hey guys!
I'm new here and, I'm glad I found this awesome place to search for (almost) everything mercedes related

I've been searching a while for a possible solution related to the following, and I'm hoping someone can shed some light on it.

A while ago, before I had to disconnect the battery, when I turned the ignition key and leave it, the engine would crank until it stared.
After disconnecting (and reconnecting, of course), I need to keep holding the key while it cranks, until it starts.

I think this is called "smart start" (I'm sorry if I'm mistaken).

Can anyone give a hint on this?

Thank you so much!

 

Not read of that one. Try a regular goole search for smart start and see what turns up.
