I have an 04 crossfire and have ran into a bit of a head scratcher. My central locking pump got wet in a story I will not bore you with but here is my question and curiosity. I know our part number is 170 800 08 48 and I know it's the same pump as the SLK like most parts but I read a thread stating that the CLK pump with the 2108002648 part number has the same wire connector slots but to many vacuum slots. Our cars only have the three spots as the CLK has a couple extra. This may be stupid but if you plugged the other slots would the CLK pump work in theory? Reason I ask is I'm getting the abs/ bas-esp light on the dash and the spoiler goes up when you start to drive. I ask because you can get a CLK pump for a 1/4 the price as one for the crossfire or the SLK.

 

I don't know about others experiences, but I bought a cheap SLK pump and it would not work in my roadster.
The pump came from eBay, so I don't know if it was any good or not.
And yes, it does have extra vacuum ports.

 

The 170 800 08 48 pump is the SLK pump so it should have worked, cheap or not, I guess it was broken somehow.

 

Yea, like in the movie "My Cousin Vinny" - "Guess the damn things broke"

 

I do not read that the OP bought or tried a new SLK pump. He only states that he has the part number and was wondering if the CLK pump would work as it is less expensive.
The extra outlets on the pump of the CLK is for releasing the trunk. The CLK key FOB also has an extra button for the trunk release so there is a difference in the electronics somewhere. The Crossfire has no truck release.
My question would be why does the OP think replacing the locking/unlocking pump has anything to do with his ESP/BAS warning light and the spoiler deploying?

 

The only reason I believe or believed it did was from other threads on here but I may be highly mistaken. From what I gathered it controls more than the locks. I think it controls the automatic light cut off when you turn of the car and walk away and somehow communicates the speed from the wheel sensors to the spoiler somehow. I may be wrong but that's why I came here to try and figure out the problem because electrical is not my strong suit. My center locking pump still works in the manner of simply locking the doors but the light delay does not work anymore they stay on and the abs and bad/esp light came onto the dash as soon as the central locking pump had gotten wet. So that is why I believe the two are connected.

 

Interesting. The Central Locking Pump (CLP) also is the Security System Module (SSM). The SSM does activate the lights flashing when you lock the car with the FOB. I'm not sure if it has anything to do with interior lights dimming. I would think the lights dimming in the interior is a function of the body control module (BCM).
Something you could try is looking into the interior of the car after you lock it with your FOB. In the center of the tow away alarm switch is a small red light which should blink after ten seconds or so, once the car is locked. The blinking light indicates the security system alarm is activated. Can you see the blinking light? If it is not blinking then you have a problem with the SSM and replacing the CLP/SSM may just fix your problems, but I wouldn't use a CLK pump. You would only be adding an unknown into a situation that is not working correctly.

If it was in reference to my post you will see I was posting about ala_xfires post.
As far as I have learnt the interior lights fade out are controlled by the CLP/SSM.
