Help Please Engine Light - DPF Malfunction

Hey guys I have same problem
I have replaced dpf sensors first on the left then even second. But management light still comes on. I had car in garage for dpf and egr clean but it didn't solve the problem. Before I had first sensor (on the left ) completely melted. Even connector. So had to cut wires and solder new connector. Replaced. Works but engine management light only comes up when I step on it so when turbo kicks on full, only then it triggers. VCDS says dpf sensor intermittent.
Help will appreciate
