I am new to the Mercedes world as I am typically a Chevy guy. My wife has a 2002 Mercedes C230 Kompressor Coupe and it has a few things I need to take care of on the car.

My first few basic questions are:
What is included in the service A?
What is included in the Service B?

Also, the car has a check engine light on and the code is:
-po412
-po410
Does anyone have any ideas what might cause this?

Also, she has been having some issues with the panoramic sunroof. It would not open for the last 6 months then all of a sudden yesterday she tried the switch and it would open a few inches and then stop then if she released the switch and pressed it again it would go a little more. Then today I drove it and the roof works perfectly. Do you think the switch is going bad?

The car is also having issues with the blower for the heating and AC. During the winter it has a hard time switching to the feet. Any ideas what might cause this?

Any help is greatly appreciated! Thanks in advance from an MB newbie!

The codes are a fault with the secondary air injection system (catalyst preheat). There was a recall for a bad relay that was killing the pump, but I don't recall what models and years were covered. I'd find out from the dealer. In some states it would be covered by a polution-related warranty extension in any case.

Thanks for the info guys! These Benz's are a whole different ballgame from a Corvette!

Panorama roof: The roof module (in the switch panel) in the CL230 was the subject of a service bulletin and a replacement under warranty. The symptoms of a bad roof module are as you describe. This is likely to mean a trip to the dealer, who has to plug in his computer to verify the fault. Could easily be combined with your trip in for the engine codes.

HVAC: The air direction switch and the fan speed switch are disabled in Auto mode. Take the car off "Auto" mode by turning off the light (push the button). The temperature control will still work and remains on automatic but you can now control air direction. Turn the fan to high and use the manual settings on the air direction dial to verify that the system switches easily between the floor, vents and windshield. If it does, your issue is likely to be with the way the engineers programmed the Auto setting. If the air direction responds to the switch and your wife wants more heat at her feet, she can use the manual settings to get what she wants.

What's a CL230M? There's certainly no CL class with the 2.3. Is it a local designation for a C230?

The sunroof issue could be as simple as the sunroof just needing to be resyncronized. It is a simple procedure and should be detailed in your owner's manual.

It's what my MB sales agreement says I bought. It's a C230K coupe, manual.

Interesting. What does the badge on the rear read? I suspect MB wouldn't badge a C coupe "CL." I guess it's some internal designation I've never seen before. Any idea what the "L" means? I wonder if Quebec found something discriminatory in the normal model number?

There's a long history of francophones harrassing German auto makers. First the French put Ferdinand Porsche in prison, then in the sixties Peugeot made them change the model 901 to 911. They had copyrighted all three digit numbers with a zero in the middle. If you remember the Peugeot 505 of the era, you know it wouldn't likely lose sales to the 911 because of customers confusing the names.

Lars, I really appreciate your help. With the HVAC, whether it is in auto mode or not if you try to put it to the feet it will try to blw the air at the feet and sometimes it works and sometimes it will not work. It will try for a few minutes and then it gives up and blows out the dash vents. It is very weird.

Yes, weird and not too encouraging. It suggests to me that the air direction switch unit could be faulty but that's just a guess.

In the good old days, when I could fix electrical problems myself, switches were hard wired to the controlled unit. I think now they just send signals down the bus. I had a bad turn signal switch that would sometimes flash no lights at all, sometimes the wrong side and sometimes it would switch sides mid-stream or stop working. Changing out the switch solved the problem, but it was done while the warranty was still active.

No offense to anyone on this board but the more I learn about these Benz's the more I dislike them!!! I told my wife she is getting a Chevy next but she did not like that very much !

I bought my C230 Kompressor basically for the power and the cool panoramic sunroof ~ which is now defunkt! It started making a terrible (yes, squeaking styrofoam) kind of noise and then hung up half way open. That first trip to the dealership cost me $750 for a new motor. Then 4 openings later, it started doing the same thing. This time the dealership tells me I need to have the whole unit replaced at an estimated cost of $3200! Needless to say, I had them close the thing and am now driving sunroof "less". Keeping my eyes open for any recalls or class action suits. I've been told that this panoramic sunroof problem is not unusual on my model. Anyone else experience the same sort of thing??

This car has had all sorts of problems with the roof, including having the whole roof replaced once already(luckily under warranty)!
