Hello new to the site and new to the benz ownership

quick question about the SLK when on cold start up the idel is very ruff if standing at the back of the car there is a poping/ missfire untill the car is warmed up is this normal for the car. ?

apart from this loving the SLK just cant wait for the sun to come out in the uk again

many thanks

Doesn't sound "normal" to me. I've never experienced that problem.

iirc: there is a specific TSB covering cold starts and should result in a flashing of your ECU.

My 2005 350 doesn't make any poping noise nor misfire when warming up. Deinitely take it to the dealer.

My 2006 SLK 350 still makes this beautiful V6 grumble every time I start it. No rough noises.

Same here - FYI, stay away from the '55's - the V8 rumble creates a desire to trade up...

ohhh the slk55 yes it dose have an fantastic sound

but i dont like the idea for the v8 ive just traded an jaguar XKR softtop for the slk and went for the 280 for fuel cost as over here its 6 pounds an gallon around $12

thanks for the help, there is no ECU light up/ or flashing, but have an appontment to see the merc dealer monday so will post results.

many thanks all

I have an 08 SLK 280, and I get some studdering with cold start-up, but only lasts about 10 sec or so. No misfires or other noises. Just shakes the car a little. I think maybe the idle at start-up may be a little low. Shiny, do you have a link to the TSB?

good idea, your right the idle is about 500rpm there abouts when warm and about 1200 on tickover, dose that sound about right ?
