    There's a 2009 Prius for sale. Owner states that is has had Hybrid battery replaced and catalatyc converter replaced. 288K miles. It has engine noise, and various warning lights. $1000. We have an 05 Prius, good engine, biggest drawback is no AC. Ours has 388K miles. Could potentially swap engines if the 09 is better. But with all the lights it seems 09 may have multiple issues. in particular can anyone tell me what the far right light means? Screenshot hopefully attached. Any other thoughts welcome. We need to decide if it is worth looking at. Thank you.

    Although blurry, the far-right warning light looks to be the Maintenance Required lamp, which means it's time for an oil change. At 4500 miles from the last time it was reset, the lamp will blink several times when you start the car. At 5000 miles, it will stay solid to let you know you're due for an oil change. After the oil change, reset it, and it starts counting again. That is ALL it is used for on a Gen 2.

    It's also pretty likely, with all those other warning lights, that the brake actuator is failing. It would be very very wise to connect a good code reader (that means capable of reading hybrid system codes) to this car to get an accurate assessment of what you're getting into.

    The far right MAINT REQD is merely a timer set by the dealership for oil changes. If the dealership sets it to "never", it's never an issue.
    The parts alone are worth more than 1000 (but not much more). If the engine turns over and the brakes work, the car could probably be made error-free in a matter of days. The catch is you have to read priuschat, not the most exciting reading.

    The engine noise is the only thing that interests me in the business so far so you're going to move an '04 '05 engine into this 09 maybe make a video or a soundbite of the engine sitting there running and go from there usually this engine does very well in the cars that it's installed in It's the people operating the vehicle and not doing things that makes the engine start making noise.
