W208 wont turn or start, key issues?

You may want to check the battery. If it's gone bad, the ecu doesn't like it and refuses to accept the key. I had a friend of mine a couple a years ago that almost replaced ignition module, his 03 CLK needed the key to be cycled like 20 times before it would recognize it. The battery seemed fine, it was holding the charge except that when cranking the engine it dived under 9V and that's how i figured it out. Hope this helps

no worries and its a good idea, to de-risk this I am using the battery out of my W140 S500 which is oversize, brand new and is removed from a working 140 to do this test!

Hi Mark.
Any progress yet?
The round pin connector is here and mine is running so happy to shoot down when your ready.
It's not as good as Star but maybee it will give an insight.

Doggy sitter, I have the latest issue of keys which arrived today along with my ignition switch so I shall try them this evening and get back to you?
