C3 2015 Hdi blue exhaust system

[Gambit]

On my car when underneath the other day, I noticed that there appears to be exhaust blow by on the joint between the bottom of the cat opposite the Adblue injector and the Flex hose part of exhaust.
I also noticed the next box along the pipe which is described in the citroen parts diagram as a particle filter has two small pipes attached to it described as particle filter pressure pipe.

Does any one know if there is a bit that can replace the burnt flange and be welded on instead of the expense of a new cat piece with the associated labour cost?

Can anyone enlighten me as to where the 2 small pipes go from the particle filter.

I am not aware that there is a DPF fluid bottle hidden away on this car , Its never to my knowledge had to be refilled in the time Ive had it from new or are there two types of DPF system on these cars.

thanks

The small 2 pipes will go to a pressure sensor some where on the side of the engine . Welding bits on to fix an exhaust isn't much good as it might flag up to an mot inspector that you have tampered with a system that's meant to protect the environment. Might be worth looking for a second hand part online and just swap it over.

Look opposite the fuel tank under the car you might see a black plastic box , if so your dpf fluid pouch might be inside it , or it might be a tank you can fill up

Huskyxantia, thanks for your response.
you realy think ive got a tank of some sort and DPF fluid- ive had the car from new 10 years never seen any comment on service invoice so surely Id get a fault come up if it was empty, ive done my own servicing for the last five years and never seen or done anything?
I will go and look though and re check the hand book

How many miles miles has it done, if less than about 70k it may not think the DPF fluid level is low yet so no warnings would be given. It is not a routine service item to check the fluid level.

The mileage is 82255 . The vehicle specific sheet telling you what to do when service wise says check at 61000 and then every 16000.
The Service light is on because of Adblue fault P20e8
I cant see anything tank wise so think I will ask the dealer parts lad who is quite good at answering questions.
