Yaris loud exhaust error
Summary of the thread
A 2010 Toyota Yaris with a gasoline engine is experiencing a loud exhaust noise, especially after a cold start, and is throwing an error. The issue is suspected to be related to defective exhaust flaps. A similar problem was resolved by checking the engine control unit for errors related to the exhaust valves, with a recommendation to have a workshop inspect the vehicle. The problem was confirmed to be a defective exhaust flap, which was repaired.

Where was the error stored, and was the louder noise constant, or only at certain times? I'm trying to figure out if it is a blockage or an exhaust component issue.

The error was in the engine control unit, related to the exhaust valves. The noise was more noticeable on startup and during acceleration. I'd recommend having a workshop take a look to pinpoint it exactly.

Thanks for the info! Took it to the workshop as you suggested. Turns out the exhaust flap was indeed defective. Repair cost was around 190€. Appreciate the help!

I had a similar issue with my Yaris. Error stored and louder exhaust noise. Is it possibly the flap actuator?
