Hi guys, sorry I know it's probably not the best idea to post two different (and probably unrelated) engine noises in the same thread, but it's kinda easier so I'm gonna do it anyway. This first noise is present when the engine is cold but has gone by the time it warms up. I think it's possibly a common noise and could maybe be the vacuum oil pump?...

This second noise is present when the engine is hot or cold and seems to sound like a bit of a gruff husky dump valve when I let off the accelerator. I initially thought the noise was when I was changing gear whilst driving, but today I realised it was when I let off the throttle and it still happens when the car is stationary...

I've had the car a year and I'd say the first noise has kinda always been there and is sometimes more obvious than others. The second noise I've only started to notice recently. Any thoughts you guys have would be hugely appreciated, thank you
The car is a 2016 (66 plate) diesel manual Octavia VRS Estate and has a Superchips Bluefin remap and a DTUK pedal box
