What engine, and ha e you scanned it for codes?
Air filter blocked ? part of the exhaust blocked ? would be at least two things to check . I replaced the stock filter on my sons T4 with a sports one made a bit of difference to economy and performance . But you can hear the engine sucking in the air more so inside the cabin than with stock . Recently I fitted one to my T5 petrol engine and also had some work done to the exhaust to help it breathe easier in and out .
