Asked in Auto Repair
Why is my 2004 Mercedes-Benz C320 running rough with smoke and an oil warning light?
A 2004 Mercedes-Benz C320 can run rough and produce smoke when a failed oil-level sensor falsely reports low oil, leading to overfilling. The documented repair was corrective oil service and oil-level sensor replacement.
