No fault code. No warning light.
But the car already telling you something is wrong.
- Power drop.
- Rough idle.
We open it up… and this is what we see 👇
- Carbon buildup on intake valves.
Direct injection engine = no fuel cleaning on the valves.
This is not “maybe”
This is “confirm will happen”.
Clean it… and the engine breathes again.
