Car is running really rough, the ESC light keeps turning on and off, the airbag light also turns off and on and check engine light is on as well. Changed the camshaft and replaced car with a new battery. Airbag light turned of, ESC turned off before about 2 hours later came back on. I don't see any oil leaking but seems oil is burning up faster then it should, have to put more oil about every other week.

Good morning,

The coolant in the oil could be from a failed head gasket from overheating. I would have a leak down test performed to verify.

As far as the airbag light, there is a fault code stored and I need that code to narrow the area of failure. The ESC also has a fault code stored as well.

The coolant in the oil and the rough running are the ones you need to address right away to prevent further damage to the motor.
