Hissing Noise and Power Loss After DPF Replacement on BMW 1 Series

Loud hissing on acceleration

Exhaust leak

Strong exhaust smell

Hello everyone, I recently replaced the DPF on my BMW 1 Series 123d due to a blockage. After fitting the new DPF, I've started experiencing a loud hissing noise during acceleration and a noticeable reduction in power. I suspect there might be a split in my turbo pipes causing these issues. Has anyone experienced something similar or have any suggestions on what else could be causing these symptoms? Any advice would be greatly appreciated. Thank you!

Check the connections and clamps on the turbo pipes to ensure they are secure and not leaking. A loose connection can cause a hissing noise and power loss. Let me know how it goes or if you have any further questions!
