Can someone tell me how to open the hood on my 2004 clk 320 mercedes?

 

Did you try and pull on the lever under the dash? It's kind of flush mount. It took me a while to find it while I was buying my CLK.

 

My 1998 clk 320 has a small lever in the ride side of the grill that you have to pull in addition to the hood release.

 

I can only speak for my 2003 MB CLK430. Open the drivers side door. Crouch down and look under the dash. You will see an orange colored handle. Pull that to release the hood lock. Then go to the front of the car and in the middle of the grill I find a handle attached to a cable, which will release the second hood lock down, pull that and open the hood.
