2008 C300 won't start
Have you checked fuses? The starter has multiple fuses that must be checked... And according to the attached pdf, check fuses 6, 7, 19 & 27 all of which are in the engine compartment...
Hope this helps!
Buttons on key unlock doors, trunk, etc... In the ignition though, I turn the key, no warning lights, no start, nothing. Completely dead. Key is recognized as it reminds me to remove it, and allows the ignition to turn.
Maybe I am just paranoid, but the key seems to fit sloppy now, like it is loose.
I have owned Mercedes vehicles for over 25 years, and my vehicles have always been well taken care of and reliable. This though, may be it. After reading all of the problems with this ignition, and Mercedes basically ignoring the problem... if I do not get any owner loyalty discount or coverage for this problem it WILL BE MY LAST MB.
5 years is a long time and a year over the end of the warranty. You can debate if the part in question (if that is even the reason your car isn't starting right now) is failing in some cars sooner than what you would typically expect for something like that, but I would have to say that 93K miles is a lot of miles and some things do start to fail.
See what the end diagnosis is and let everyone know the outcome before completely writing the marque off.
I understand that to most, it is their own experience that counts, but more importantly, it seems that most people posting in this thread are under a huge misunderstanding and a great sense of entitlement to something that defies logic or common sense. I've asked this question in this thread several times and have received no answers... But I will pose it again just to make the point:
Can you name one single car manufacturer (or as a random example -a coffee maker manufacturer- for that matter) that will cover a part failure at any time past the manufacturer's warranty?
Just ONE! I haven't heard of any. And to anyone who as had a different experience, (and one that has been established as standard procedure - meaning it is offered to whomever asks) please offer some details. Yes, manufacturer's might offer a once in a great while good will gesture to someone based on particular circumstances but to do so each and every time, is unheard of. And expecting a different answer is only designed to leave you disappointed with a sour/bitter taste in your mouth.
Furthermore, anyone who tried to say its a "common" problem is only fooling themselves. For Mercedes Benz to decide to use this part on 141 of its model, only to have us document a failure rate of 0.02% (a very rough estimate I made in a previous post in this thread) is actually a testament to that part's high reliability not the other way around. Even if the error rate in my estimate higher by 10 fold, it still stands at 2% which by any standard, is acceptable and not high!
And lastly, for those saying this will be their last MB, by all means, go try your luck with other makes, and when you run into parts failure after the end of the warranty, come back and let us know which of those other makes was willing to cover your repair bills.
But that is not all.... Because according to this: "NHTSA imposed a $3 million civil penalty to BMW in 2012 for similar violations", BMW is a "repeat offender" of the same thing that you are so desperately trying to pin on Mercedes....

[QUOTE=Glamgrrl;6696858]Now my question is - what does this mean/QUOTE]
Understand that any answer would be speculative at best. It could mean that the locking mechanism got stuck, then again, your description you stated that the steering wheel was unlocked. So it may be an EIS problem. Or it could be something else. I will say that if the steering wheel is unlocked, then wiggling it is not likely to get ELS to release because there is nothing to release when it is not locked.
As for wiggling the fear lever, it would seem to me that the command to release the gear level will occur after any functional switching between EIS and ESL has already been done. So I am not sure how wiggling that part will aid in overcoming an no crank/no start caused by other EIS or ESL failure.
I can tell you that it happened to me once, a few months back... and yes, every time I would go to start the car, I was anxious and concerned about where I was and whether it will start ore not. 15,000 or so miles later and it has yet to fail.
Good luck and please keep us updated.

Edit for additional details: 2010 C300 105k miles

1. This is the "fob socket" in its state when no key is inserted:
And, this is the "fob socket" in its state when a key is inserted into position.
As you can see, the part that moves to cover the openning when the key is removed is not a flap type door, but instead, is a piece of black non-transparent plastic, that the tip of the key sits on, keeping it flat and pushing it farther into the ignition lock module. So there is no need to stick your finger there, or use a q-tip as you artempt to clean this mysterious black substance you happen to find there.
Now, for your suggestion that your car would not start presumably because some mysrerious black substance somehow ended up on that part of the ignition lock possibly blocking some sort of signal that they key was attempting to transmit to the ignition lock, and when you cleaned that part, lo and behold, your car started after showing no sign of life for two straight days, could possibly be based on your seeing that the tip of the key has a round translucent piece of plastic which would lead you to believe that to be a part of some visual signal that the ley uses when engagjng theningnition lock... Fact is, that translucent piece of plastic at the tip of the key fob does actually transmit an infrared signal, but this has nothing to do with the cycle of attempting to start the car/engine. Instead, that signal, is utilized as part of the "Summer openning procedire described here:
Even if anything that needed to be wiped in order to enable any part of the starting cycle, it would be your key and not what you concluded was a "dirty socket"...
Also, I am not aware of any "tick, tick, tick" sound that would be related either....
Any one know if there was a recall for this on the 2008 C230?
Reason I ask is I just bought a 2008 C230 last month and I asked the dealer about this issue and if it had been replaced in the car I was buying. My MB dealership said they have never heard of this issue.

I did a recall search on the interwebz about my car and found no recalls for it really.
