I'm not sure what you mean by "check if anything needs to be replaced". If the car is running fine, then nothing - especially at just 3 years of age and only 10k miles) needs to be replaced except for changing the oil and oil filter. You can find out specifically what needs to be done in the maintenance schedule which should have come with the owner's manual. Or you can find it on the internet. There is especially no reason to ask a dealer if they can find something wrong to replace under warranty - do that at any auto repair shop and you are begging to be parted with your money. If the car and all its accessories are working fine, then there is nothing to replace.Ok awesome ! Thank you guys ! I’ve found a few local Mercedes shops near me and will go to them for the next service and have them check if anything needs to be replaced .
