Happy Sunday,
So I have this issue with first time start cranked but died right away, and than no crank, no clicking noise, just silence, light on, thats it. Now before I start guessing I am waiting for my OBDII from amazon . Meanwhile found a spare RCM that came with the car. Probably an OEM part. Attaching pics so you guys can tell me if this RCM is legit or won't work before I adventure to change it.
The box says MEYLE and RCM looks new but after I saw the pics you can see it has scratches on the green board, so it has been fixed before. Please guys, let me know, I need to resolve today !!

 

It takes 15 minutes to swap them, why not try and see if it makes a difference?

 

ok, I will do. Lets hope I can get it out and reinstalled. Don't seem I could make anything wrong. Got the pictures from the forum. Thanks!!

 

nothing works, same as before. I looked at both RCM's and they seem fine. Tightend mentioned to me SKREEM. Is there a working link to understand what it is and if I need a mechanic fixing it and $$$$ ??

 

One way to check is to disconnect the negative battery terminal for a few minutes and reconnect. Usually, if it is the screem, it will try to start again a few times and then nothing again. If it is the screem, contact The Mercedes Swap Shop (MSS) online and get instructions. They repair them.

 

I swapped RCM's (pretty easy) and the car did not even crank the first time like before. I swapped them back and it cranked stronger than the other times and I thought he is back, but died at the end, lights on, door open beeping, radio engaged. The 2nd time and 3rd time only dashboard lights on and no crank, no noise at all.
I ordered a new RCM on Amazon for sale $123 , arrives tomorrow and we will see. My OBDII reader should be here in a few. If no faulty code shows I bet its the SKREEM.
Don't think has to do with CPS, but I have one just in case. What do you think is going on?
A weird occurrence I had 2 weeks before, dies at the red light on my way to work in the morning, but restarts just fine. Later dies again at another red light, I than tried to avoid it by turning off AC and Radio because while engaging to close the window it gave me weird sensation whether I felt a growling like it did not have enough power or I heard it I can't tell.
I also thought about bad fuel since I put $15 Chevron (I hate) Super Premium, the weirdness started that evening before the red light issue.
Maybe that helps indicates something.
Our streets are bad here too, on my way to work (I speed) there is a stretch ( I try to avoid) where the car gets roughly shaked and its possible something is getting lose somewhere.

 

where r u?, Matt is in SF he is heading North in a week or so. text him tell him where u r and what the problem is ,,,he will call u back within a few days,,, I am in Indialantic fl jim

 

I texted him Sat night but has not answered yet. Meanwhile I did OBDII scan and did not reveal any codes.
Now I know what happened. I must have lost the RF chip in my only remote I have. I am looking for it everywhere. I lost it when I locked my car. The housing tends to open and it probably slipped out that night.
if I would have a picture how small it is and how it looks like I would understand if it is worth looking for it outside.
what a mess

 

Look under ELECTRICAL and rebuild your key fob for photos.

I think you have two flaky RCMs. I'd almost bet money on it.
The only way to know is to have DJ rebuild yours OR put in a NEW one.

RCMs are FAMOUS for doing just what your car is doing. The BIG TEST is to turn the key to "START", if you get no starter engagement, release the key to "ON".
If the engine cooling fan warps up to high speed in about 30 seconds, the RCM is bad. PERIOD.

The fact that it started and then died using one of them, after you messed with it, even reinforces that it's the RCM..

 

A big thank you to everyone sharing their knowledge to figure this out. There is no better place than asking experienced Crossfire owners when your mechanic is not around.
I was finally able to talk to MATT, my Crossfire mechanic here in Miami. He knows Crossfire like his pockets. Owns several and fixes those cars all the time. If you need help ask here for his contact info, if you are looking for a Crossfire ask him.

It took him no time to figure out that the issue was the SKREEM. RCM works fine. Will get my car back in 2 days.
I did not lose the RF chip in my remote either, but the story behind it is way to long to explain. Only one thing, when you buy a Crossfire, check it out with an experienced mechanic who knows Crossfire before you spend your money. There is stuff people do to shortcut a repair in a way they shouldn't.
