C button?

erm, Cancel?

Or is this a 'post a random button thread' in which case I choose, RADIO ;)
 
So you have return left side and cancel right side! Perfect,two buttons for the same sort of thing!!
 
Suspect it's Comfort/Sport mode button for the transmission. In comfort mode car pulls away in second and changes up at 3k RPM, in sport it holds the gears to 3500RPM. With the engine on, look at the bottom of the speedo where it tells you which transmission range you're in (D, D4 etc) and on the right it will say C or S, changing as you press the button.
 
Pressing the C button Calls ghost ninjas to do karate chops
 
Simple question! Would of liked to have found someone who knew!! F#$k me! Nice one guys! Just hope I got the spelling right!! Parents could not afford posh school!! But at least I own my car outright!! Any simple questions! Next time I won’t ask

FTFY Not sure why a posh school is the only way to learn the language.
 
You haven't quite got used to the banter and sarcasm of the forum yet have you?

Give it time and you'll get an answer to almost any Mercedes question you ask. But be patient and crank the sense of humour up a notch.

As for your question, I don't know, but looking in the user manual will tell you.
 
Looked in the manual could not find it! That’s why I asked, I do banter, don’t do sarcasm and not starting now sorry,
 
Hi everyone,
I am unable to start a new thread, this is why I am replying on this one but with a new subject.
Massive apologies for this
I am new to the forum, sorry if I highlight the same issues here, but still cannot find the info I'm looking for.

2007 E320 CDI with 140000 miles on the clock
Wouldn't start in the morning (temperature outside 8+ C so not cold at all). If I keep the ignition on for 2 minutes, then it starts straight away. Does this sound like a lazy fuel pump or air in the fuel pipes? This only happens when the car was parked for a night or so.
As soon as it starts first time (after waiting 2mins with the ignition on) , if I turn the engine off right away(without letting it warm up) I will turn the key back on and it will start straight away, easy, like it doesn't have any issues.

Had it scanned yesterday:
2195 o2 Sensor
2270 Glow Plug
2138 Glow Plug 6
2137 Glow Plug 5
Nothing showing on the fuel system

Would a Star Mercedes diagnostic unit narrow down and point directly to the problem?

Despite that I have 2 x glow plugs faulty, I remember my 2007 CLK 320 cdi had the same plugs faulty but started first time every time, so I am thinking of a fault with the fuel system and not the plugs. I will change the glow plugs anyway, but just need your advise guys as I can see that some members have a very wide knowledge here.

Thanks in advance
 
And if you want a good answer you'll ask a good question with correct spelling (*too*) (COMAND) and grammar .

Not sure if I missed the joke, but there are multiple grammatical errors in your own post. :wallbash:

Did you see the blue "Post New Thread" button just under the top banner?

Page 19 in the Comand user manual shows the C button as the "Clear" function.
