07 c230 check engine light?

My check engine light just turned on tonight and when it did I smelled maybe burned oil or something in the car.. Yesterday I reset my service warning because it's been past due about 20 days, but I haven't actually had service done on the car yet. In the instructions to reset the service warning it told me to pick an oil type so I randomly selected one and reset it. Could that have anything to do with it? If not, what could be the cause?
The car has 37k miles

You need to get the code that is stored, that will give you a better idea what the check engine light problem.

Hmmz.. recently, i seen a 07 c230 had check engine light with about 45k mileage. The problem is the Magnent solenoid. Total of 4 and there are 2 that had to be changed out. Oil was leaking out and into the solenoid causing the check engine light. You can do a DIY on this. Part is inexpensive and easy to remove and install.

Thanks, I'll check the codes first thing in the morning. Hopefully it's nothing major.

Get a cheap code scanner, or have your local parts store scan it for you. No sense trying to troubleshoot w/o it. On your 07, the most likely is the p0012,p0015,p0022,p0025 magnet issue like 04mbc230 said. No worries there is a big thread that covers it completely with part numbers and instructions.

Just got back from my local auto parts store and the OBDII showed p0128 which might be a faulty thermostat, coolant sensor or just low fluid level. Will troubleshoot this later in the day, could just be low on coolant. It's a Cali car I bought half a year ago and never even got around to check the coolant.

Edit: Just checked the coolant level on a warm engine. It barely reaches the black spot, the manual told me it should be on top of it. I'll have to add some, but is it the reason the check engine came on for that little coolant missing?
I also haven't noticed the temp gauge fluctuating, so I don't think it's the thermostat.. will do some more driving and keep an eye on it to make sure.

Glyn, but that doesn't resolve why he smell burnt oil.

So aside from a new thermostat, there is also another issue about the burnt oil.

oohh.. he said "maybe", well, perhaps he should check. But burnt oil and burnt coolant is two seperate animals. Well, regardless, you should check to see if there is a leak and if this needs to be change since there is a high chance the magnets may have failed.

I've driven around for a little bit today and didn't smell anything, tomorrow I'll go for a longer drive and check.

Thanks Glyn!
Is this the correct part # A 272 200 01 15? Do I need anything additional to that?
How much of a pain in the *** is it to change myself?

That's great. Perhaps it was burnt coolant?

Well, it hurt if you check if there is a leak on the magnent solenoid. Just lift the front plastic off and you can see the magnent solenoid. If there are oil, then you have a developing problem. You can always wait till a check engine code to light up before changing. It's up to you.

Just got back from a 30min drive. No smell, but I did notice the temp going up and down between 55 and 75. So it's definitely the thermostat, right?
I'll definitely check on the solenoids.

As glyn said. You need a new thermostat. Them should be at a little over 80 for normal.
