Exclamation Rough Starts in the mornings

Hello guys!!

I'm new to the forum. I have a Mercedes-Benz C200K. The car has 72000km on. We had the car for about an year and then it started with the rough starting especially in the morning or when it has been standing for a while. What the car do is when you start the car it starts but the cars runs roughly for about 3sec and then the computer gets the revs up and then it idles fine.

What can be the problem?? Any help will be appreciated!

Thanx

it's most likely the throttle body, I had the same exact issue with mine:

after having replaced the throttle body, the car runs great again.

no problem.

the labor is relatively easy, but the part itself is costly (about $600-700 from the dealer).

Where are you? 200K - If you are 2005 you should be out of warranty.

About R7000 - I would have a go at servicing the TB before tossing it - Let me try & find the pics.

Here is the inlet diag. Item 200 is the TB. See a few TB pics - for M111 engine but identical in layout. Service everything. It's pretty simple & worth a bash.

I really don't know. Ask the service manager at Culemborg. You know how it is these days. No one fixes anything, they just change parts. Also make sure the basics are right such as Plug leads, coils & plugs. Are you throwing any codes? Get someone with an OBDII scanner to check for codes. OBDII port is under a drop down flap under the steering column
