Changed my dpf pressure sensor but one of the pipes looks to have been cut. Anyone any ideas as to why? Only owned the car 6 months and recently had dpf issued and limp mode. 

My Superb is exactly the same.

 

Earlier models had 2 pipes on that sensor that both connected to either end of the DPF.

 

Now it is connected to the DPF by just the 1 pipe, the short stubby pipe senses atmospheric pressure.

That sets my mind at rest. Thought it had been cut for some reason. All the videos i watch, one of the pipes goes before and one after dpf. Thanks for the reply
