Dump Valve Noise

[np1234]

 Hi all,

this noise has become more prominent.

 

cant work out what it is and don’t want it causing damage.

 

any help appreciated!!

I'd recommend a diagnostic check to see if any fault codes flag up. Definitely get all hoses checked relating to the turbo.

I hear the dump valve noise when it is passively regenning the dpf. I also had it when the air filter was replaced recently & the cover was not fitted back correctly.
