Car feels very different after 1st service

[sk546]

Hello all,

I recently had my car in at the dealership for its first service. The service itself and the dealership were all good with the majority of reported issues being sorted at the first issue.
The main issue I'm now experiencing is that since the first service, my car feels very different to drive than before the service. There seems to be a lack of mid range pull when using the petrol engine (very noticeable on a dual carriageway when in top gear, before it pulled like a train from 60mph but not so much now), the steering feel and even the brake pedal feel are now very different.
Being the PHEV, the progression between the regen braking and the physical brake system braking was very progressive and felt easy to modulate before the service where as now, it is quite difficult to modulate and the physical brakes come in very strongly at odd occasions with no more pedal application.
Has anyone experienced similar following a service?
Is this likely to be a software update that took away the previous car calibration?
Is the car likely to return back to the previous setting after some driving or is this new calibration what I have to put up with?

It may settle down with a bit of self learning of your driving habits but unlikely.... Can I suggest you tell the dealer what you are experiencing, and ask them what they have done to possibly cause these symptoms.It is quite likely to be software related but unless you feed back what you have found, the developers won’t know and can’t rectify for the future.

Your motor still making the humming noise mate or has it since stopped?

Still quiet for the time being. I am keeping an ear out just in case it starts humming again.

So, the noise had gone for a while but but it was back in style this morning, especially noticeable on tight right hand turns with power on. Even had a slight grinding sound to add to the usual hum.

Its defo going back to the dealership.

So, my P* Engineered went back to the dealership for them to look at in reference to the car feeling very different following its first service. A large software update was found to be still available for my car which was installed with a Note mentioned on the paperwork stating 'All software is now up to Polestar spec'.
Although not directly mentioned, I suspect my car was updated with standard T8 software rather than for a Polestar Engineered car. Well, at least its all back to feeling normal now.

In relation to the ERAD noise in electric driving, the dealership looked in depth this time and found a fault code stored. They recalibrated the IEM (Inverter Electronics Module) clutch engagement to see if this fixes the issue but they suspect a camring fault should it continue.
