Rough Idle
So I have owned my 2000 CLK430 for about two days now, and today I noticed some problems at idle. It is not too terribly bad, but it is enough to raise my eyebrows. When I am at a standstill, the engine gidles up and down and the RPM needle moves up and down just slightly. Along with the the temp guage moves up past normal. Once I start moving, everything seems fine, and I hear nothing wrong. Any ideas? I am going to look at the air filter once it stops raining, but I am not sure whether to bring it back to the dealership where I bought it at and use my 30 day warranty or to drive the 50 miles to the Mercedes dealership and pay out the ying yang. I just don't like the idea of a Kia dealership working on it (thats where I bought it). thanks in advance to any suggestions.....

JMA
Motor mounts (not likely if tach is jumpy)
MAF
Harmonic Balancer Pulley
Bad wires
I'll bet that any of these will cost you at least $500 from a dealership, so I would mention these to the tech if you are going to try to get it fixed gratis...maybe they can benefit form the research?
Good luck-

Per Mercedes (and a number of peeps on several forums), the rough idle on the CLK is "normal".
The last hope I have is to get the ECU tuned. I'm hoping to smooth the idle and get about a 20-25 HP gain. I'm going to try to organize a group buy for a Powerchip ECU remap so check it out if you are interested. They offer a 14 day money back guarantee.

Yeah, im interested in the powerchip...its around 850 dollars, right? i'll do some more reading on it, but what all is involved, do they send a new one, or what? anything else need to be done to the car once its tuned?
thanks again for the info, and keep me updated

When I'm driving the car, it's fine. When I'm on standstill, the car is kind of shaky/gidles a little. I notice that my temp guage is at normal temp. for a while then it starts raising above normal.
If you find out anything from the dealer, please tell us your result here. I'd really like to know. I still have my warranty.
i have no idea! i have only owned my benz for a week now, so i am still doing my research. it would be nice to hear feedback from someone that has sent their ECU to them though.... im just wondering why they would charge $300 less for supposedly the same gains from powerchips...who knows.
does anyone have any pics of a white CLK on black wheels? im wondering how it would look. i found some wheels i want, but i am not a millionaire...have you seen the maya rt5s?

I'm not that worried either, I'm mostly worried about the temp. gauge. I don't like the fact that its above normal. Engine could be over heating. (Had a bad experience with that last year in June)
That happened on my BMW 740iL. I flew to Los Angeles to test drive it/look at it. I bought it. The next day when I drove it back to San Francisco, half way through the trip, I noticed my Temp Gauge at nearly the red shaded area. I stop for 10 min, its normal again and I drive. I kept stopping every 15 min till I got to the gas station. I put cold water in the coolant (or whatever its called).
Anyway that worked for a while. It resulted in me replacing my engine.
Warranty replaced my:
- Engine
- Rear Main Seal
- 2 Drive Belts
- Spark Plugs
- O/F Housing Bushing
- Intake Cover Gasket
- PCV Cover
I had to replace/fix (without warranty)
- rear transmission mounts
- rear lower control arm bushings
- car pulled to the left
- srs light came on then off
- parking brake did not release all the way
- a/c needed recharging
- power steering reservoir mounting bushings needed replacement
- dip stick was broken
- Thermostat
- Intake Manifold Gasket
- Fuel Hose
- Cylinder Valley Gasket
- O-Rings
- water accumulator gaskets
Too many problems with that car. Now its in perfect condition. I even have a 1 year engine warranty.
I just want to take care of my car problems right away before it results in major problems.

does anyone know why it is "illegal" to get a VMI from the service center on a car? i drove 45 miles to get one and the lady said they can't give me one or show me one, and just said they look at it everytime prior to servicing a vehicle...well, that really doesn't help me out!

Yeah, I really like cars. I just got my Range Rover a month ago. My CLK was for sale for awhile, then I decided it was too much of a nice car to let go.
My BMW will be gone soon. I'm going to sell it after they fix all my body damage. I was spinning on the freeway a few weeks ago in Nevada, it was snowing. I have $8k in damages. Once all of it will be fix, the car will be for sale. I spent too much money on the car lol. Don't want to spend anymore.
I will def. take my CLK to Mercedes Dealership. For some reason I doubt they'll find a problem with it.
