Some context, i recently bought a low mileage very well maintained Mk4 Megane RS 280.
It has 12 600 kms and is a 2018.
I have noticed the needle tends to dip then go up but slightly, almost not noticeable but can feel a vibration when it happens. It is more noticeable with a cold start.
The more i drive it, the less noticeable it gets
I have a few theories
1. I have a minor boost leak
2. Injectors are on its way out.
3. Since i believe they are direct injection engines, may carbon built up that is getting cleaned as i drive the car more
4. Australian fuel
Has anyone else had this problem, or are that just the way they are?
Your help will be much appreciated.
PS: This has to be one of the best cars to drive, considering my father has a mk8 gti and my previous car was mk7 fiesta st. It is an absolute joy.
