Engine ligth on - 2007 Mercedes-Benz C230 Sedan

Blown fuse or a loose ground strap from engine to firewall.

If you can,go to Autozone,they will test your battery and alternator for free,only takes a few minutes,on your brake light,check brake fluid in master cylinder could be low, setting the sensor off.If your brake fluid runs dry,you will have to bleed,you may have a brake leak and check your brake pad and shoes,may need replacing.

JUNK IT

well, if check engine ligth on have the codes pull to find out the problem it may be mapp ,air ,sensor bad ..if engine ligth is on its picking up a a code..

engine check light. needs a computer scan and check. needs a workshop.

You knowed what code are there? Read the Check Engine Codes

If you change the sensors, Reset the ECU, sometimes they keep stored in the mmeory.

Hope this help; good luck (remember rated this help).

Service engine soon is telling you to check computer for trouble codes. You can sometimes disconnect battery for 10 seconds and codes will erase. It is a good idea to have them checked. Most Auto stores like Autozone will check for free. You may have to call around. Most repair shops will charge $40 to check.

there are four O2 sensors,you need to check the sensor on the drivers side exhaust,the front O2 before the converter

check the two vent that the valve hooks up to are not clogged or restricted they usually plug up with carbon

hi it sounds like you've "cooked" the engine lost all water and blown headgasket unfortunatly this will be a very expensive repair and depending on the amount of damage to the top end COULD mean a replacement engine chris
