This is listed as an open campaign for my C300, and I have no idea what it is.

Can anyone here decipher this?

205 EVAP SYSTEM, OPEN 2014-12-18, Campaign Number C1A141201

 

Is this an error code that popped up?
Its looks like its referring to the Evaporator System which is AC (I think)
Time for one of those code diagnostic boxes.


If its not an error code then its some MB internal service code would be my guess.

 

No, it's just listed for my car under my MBRACE account. No problems at all. I believe the EVAP is part of the emissions control system.

 

It's the EECS. Evapourative Emissions Control System. Filler, tank breathers, charcoal canister & purge valve into the inlet system.

They must have a glitch. It should throw a code.

Typical codes.

Thanks, Glynn. That will get done when the car goes in for the bleeding seats fix.

 

Stan ~ if there is an actual leak they must smoke test the system & locate it. It might be something stupid like they did not tighten a clamp properly. On 2005 W203's the filler pipe used to crack in a very low proportion of cars. Will be interesting to know what the issue is. Please ask them.

 

Doesn't a campaign signify either a recall or corrective action by the manufacturer on a part that may be faulty?

 

This Customer One Action has been initiated, as an audit, to verify the functionality of the evaporative system on affected vehicles. An authorized dealer will perform an evaporative system check using Xentry and open a PTSS case for further instructions ONLY if an evap leak is detected. Vehicles in dealer inventory must be checked prior to vehicle delivery. To perform the test the tank fuel level must be between 30% and 90% full.

 

Thanks!

 

Good stuff!
