I bought a second hand 2018 Mazda CX-5 2.2 diesel skyactiv AWD in August 2022. It has now 78.000 km.
Since I bought it, it always revved up the engine automatically to 1800 rpm on cold start for around 10 seconds and then slowly goes down to idle. I thought this was because the engine was cold. The thing is, lately it randomly does it or not. I can't find a pattern. I just find it weird that with the low winter temperatures it sometimes doesn't rev up.
Is this expected?
Thanks!
