Blowing sound not egr on 204ps

[4motionbitdi]

Hello we purchased a T6 EGR cooler delete kit for a 2016 204 bi tdi which consisted of the pipe and the blanks. Darkside kit. we have a video of the issue we're having since we fitted the kit, but I am unable to post here. we're getting a strange blowing sound coming from above the rear EGR blank area the engine will run for about 15 seconds and then shut down we're struggling to work out what this is. It's coming from a oval shaped port with a material flap over it. The ovel hole is roughly 20MM x 6mm. If you put your hand around the back of the engine you can feel a flap. The slot is under this flap.

Any help would be appreciated.

Thanks Dave

Any pictures of the port?

I've got a photo of the area but you cannot get the camera in to take a photo as there's a flat in the way. Strangely flat is made out of some kind of material.

I have a video where you can see it blowing.

Under the fabric is the differential pressure sensor for the DPF. The two rubber pipes connecting in are from either side of the DPF to measure the pressure variation.

Thank you for that.
Makes sense
If it was leaking would this cause the engine to cut out?

Can the hoses be crimped closed to diagnose the issue?

What is the ovel port? Could it it where the plug fitted and now the pins have and plug have blown off?? Sound unlikely.

Here is a picture of it blowing out. It not coming from a pipe it is coming from an oval port almost the same size as the plug on a sensor.

If you unclip the fabric you can take a look at the sensor to see if something doesn’t look correct. A new sensor is approx £50.
