Hello, I got a 37K driven 2018 Oriel yesterday. I have another oriel (2017) in my office with a colleague. I noticed that when I start his car up, the sound is a bit like a conventional starter motor and then the engine comes alive. However, when I start my car, there is a strange boom at startup. It is difficult to explain but it sounds like I am starting a sports car. Not that I mind this
, but of course I understand that there should be no difference in startup sounds between the two cars.
Once started, both sound more or less the same.
What kind of a problem could it be?
