Hey y'all from Houston, TX.

I got a new code scanner and it goes beyond standard ODBII codes.

I'm learning.

I need to point out, I have no lights on, but I do have a pending ODBII code P0455 Evap System Leak Detected Large Leak Detected.

Do I even need to concern myself with these mercedes specific codes?

P2013
P1174
P1212
P1135
P1134
P1130
P1131
P1132
P1035

 

Here is our code list

Diagnostic Trouble Code (DTC) List

 

Just my 2 cents:
Start with your gas cap, that would be the cheapest cause of a leak. Especially if you have a cheap aftermarket replacement.
Mine caused the gas light to flash and eventually the check engine light came on. One of the codes I got was the same as yours and the other was also Evap leak small. When I put the original back on everything was fine.

 

Thanks for the reply. I might not have made myself clear, I'm not trouble shooting the P0455 ODBII error, at the moment. I've bought a new gas cap only to have the same error. I'm not worried about that, right now, I'm trying to learn about the Mercedes specific codes. At the time I made those readings, the P0455 was "pending", no MIL light on at the time.

 

OK, So here's what I'm looking at. I know about the Evap system leak. Not concerned with it at the moment.

CAN communication fault, I "THINK" this is related to the IC Instrument Cluster error.

Coolant temperature sensor. B10/8 B11/4, does this actually mean my coolant sensor is bad? Is there more than one?

Control Circuit SN1, I have no clue what this means.

RFL, radio Frequency Locking, Electric Central Locking, I think this is because my siren is disconnected? I have a new one to install tomorrow.

what do y'all think?

 

So I checked and the siren module was NOT disconnected. I replaced it with the one that beeps when you lock / unlock the car with the remote.

Mercedes p/n A 219 820 32 26 64.
AutohausAZ p/n MB-219 82 03226.

How do I "set it off" ?

now, I will check the codes again.

 

I think you can test it by rolling down your window and then lock your doors with the fob. Then reach in and try to open the door with the inside handle.

 

that did not work

 

could it be it's only "set off" by jacking ?

 

Maybe these links will help.

My 2007 alarm will activate if it's on & I attempt to jack up the car.

 

My 2007 alarm will activate if it's on & I attempt to jack up the car. I've had to turn off the alarm multiple times. Can't seem to remember that fact. But I am 73 years old! CRS Syndrome - Can't Remember ****!

 

CRS is real, I'm 60.

I did what someone suggested rolling down the window, lock the car, wait a few, then reach in through the window and open the door. The siren did sound.
