Hi, I can understand what you are going through. I have a 2015 Seat Leon and recently had similar problems. For me it was the EGR valve that was blocked, causing the symptoms you described. It was a serious problem as it could have seriously damaged my engine if I hadn't dealt with it. The mechanics had to clean the valve. I would advise you to have it checked to avoid more damage. But as I said, this is just my personal experience and could be different in your case. Stay calm and smart!
