Srt turns over three times with a no start then will not turn over until you disconnect battery and let set for 15 plus minutes

 

Your screem is bad, contact SOS Diagnostics.

 

thanks - just contacted them - so I take it you have the same problem ? It going bad - Would that have anything to do with replacing the stereo or replacing the module in the trunk that communicates with the key to unlock and lock doors ?

It is a classic SKREEM (acronym) issue. More may chime in but I don't remember any other cause for the symptoms you present. Good luck!

Not nessesarily. Fact is, the SKREEM failure is rather common, many of us know about it even tho we've never experienced it.

Probably not.

Possible. The CAN BUS that runs between those two modules is a direct connection, so sure, it is possible.

 

SOS can take care of you but Needswings.com (Rob) is a long time well known provider of parts and accessories here any personally I choose to work with him for this or any other parts I ever need for my Crossfire

Please share your solution because that is our learning tool.

 

how would I even check that before sending Kareem/ecu and key out ? Doors didn’t seem to be unlocking correctly
today When hitting key pad .. lights blinked compressor that send air to unlock doors seem to struggle

 

IF the pump reacts, then the SKREEM and pump/controller are talking fine. A 'struggling' pump would imply a bad pump or low voltage to me, not a CAN BUS issue.
This can be caused by a weak battery, corroded (due to water in connectors) wiring, or just a worn pump (not likley on that last option).

 

Any codes been set?

 

no codes - scanned it yesterday

 

just went back through my notes .......

car would not lock / unlock for wifey- then it would not start at times - i found the anti theft module and door locking vacuum pump sitting in water in the trunk ( trunk must of been leaking)

Replaced both items with used parts - car started and ran well

started acting up again and found the leak was not fixed and water was back in the trunk and corrosion was there

replaced them again and still will crank three times no start and would not crank without disconnecting and reconnecting battery - then the same thing happens

did notice yesterday when hitting the unlock lock button - very slow moving and pump runs a bit longer then usual

just wondering if i should replace anti theft module one more time before sending skreem and ecu out

any suggestions >?

 

Just in case you do not know a generic OBD II scanner WILL NOT give you the codes you are looking for. You must be able to dig into the Mercedes diagnostics. A proper scanner can tell if CAN BUS is a problem and distinguish between the SCREAM and the Anti- Theft alarm. The Crossfire SRT 6 will scan as a Mercedes 2003 SLK 32 AMG.

 

S.O.S. are excellent people but there are (or was) other options. One of them is immobilizer delete ..

 

Has anyone else on here done the immobilizer delete from those guys? One of my two Crossfires is missing the SKREEM altogether, and I'm considering just doing this delete. Can you unlock the trunk and gas cap with the unlock buttons inside the car if you do the SKREEM delete? Are folks who did it happy with it?

 

I heard a few stories, all of them seem pleased but this 3rd party opinions
