My C280 will sometimes start missing real bad and won't stop until I turn the car off for a minute or two then restart it. That usually takes care of the problem, but it seems to be happening more and more often.
In an eariler post I was told that the 3 coil wires may need to be replaced. Is there a way of testing them to make sure it's them?
I haven't changed the plugs yet, so I will attempt to do that this week but I thought I'd ask if mercedes has any kind of trouble codes that I can access. Or is that something that will have to be retrieved off a dealers computer?

Oh yea one more thing, I had disconnected the battery, in hopes that it might reset the computer and fix the ruff running problem. Now the radio dosn't work. I was told that there is acode in the owners manual for that, but nowhere in the owners manual I have says anything about the code to reset the radio. Where else might I get this code?

Thanks, Shawn
