CLK 280 MBZ brake left lamp on indicator is being displayed

I couldn't find clk 280 in my US database.
I did find 3.0L/2996 cc
The firing order for v6, 143625, 2006 model year. I figured no matter what model had this engine, the firing order would be the same, correct?

p0355 indicates that engine misfire is present.

p0305 indicates that the misfire is in the cylinder number 5

Have the spark plug tested/replaced and test the cylinder number 5 spark plug coil.

You must have the dealer service dept scan the system to see what is causing the fault.

have the following checked:

1. ignition timing
2. valve lifters / tappets
3. rod bearings

When you are using the keyless entry you are flashing the turn signals... which are also the brake lamp filiment.
The park lamps on that side of the car simply dont work.
There is probably an open somewhere in the wire to that lamp. The lamps are fed through the wiring harness on the drivers side. Your break in the line is somewhere between the left and right in the rear. You can try to find it or run a jumper from left to right under the rug and save some pain. Your call.

If the brake sensors are rubbed through than you need to change the sensors in order for the light to go out.

This indicates that your brake pads are worn bad enough for the warning light to come on. You need to have new pads put on the front before they dig into the rotors and have to have them turned as well. I would do this asap.

Most likely cause is the 'stop lamp switch'
It is a electric switch located on the brake pedal inside the car, about half way up on the brake pedal.
Pretty cheap too, I think the switch is only like $25 bucks.
2 connectors on the switch and then it turns out.
hope that helps
