Hilux EGR Valve Issues

Sounds familiar. I had similar issues with my Hilux. Reduced power, rough idle, and the check engine light were the main culprits. Have you noticed any difference in vehicle emissions or any unusual vacuum leak noises?

Yes, the emissions seem worse, and the hissing sound is pretty loud. What was the cause in your case? Was it definitely the EGR valve, or could it be something else like the catalytic converter?

Yup, it was the EGR valve. I tried cleaning it, but it was too far gone. Honestly, save yourself the headache and take it to a workshop. They can diagnose it properly and replace the valve. It's like trying to fix a leaky faucet with duct tape - sometimes you just need a professional.

I took it to the workshop, and you were spot on – it was the EGR valve. The total repair cost was 355€. Runs like new again!
