C4 Picasso making noise after engine off

Post by Longd2002 »



Click on the link to see the video. The car is running fine, no warning lights whatsoever. Just when I turn the ignition off the car makes these noise for 30 seconds and stops. It’s been like this for 3 weeks. Anybody knows what this might be?

It's likely to be the EGR valve. This is cycled after key off to help keep it moving - it's not supposed to make that noise however 🤣
