Volvo S90 - random warnings

opexpert · Feb 17th, 2021, 13:45

Hi last October I bought an S90 from 2017 diesel, automatic. Car drove fine up to last week. Usually before going to work , I have the car started from iside for 10-15 minute. But last thursday, temperature was -12 degrees, driving to work I get 2 warnings: Auto hold service required and Parking brake service required. Also when I had a look at oil level , it was overfilledCalled the dealer where I bought the car, which is not a Volvo dealer, and they tell me to take the car next day to have a look.They come back to me , telling me to book the car with a Volvo dealer as they couldnt connect to my car.
Called Volvo in Leeds and I`m booked for this thursday. But Tuesday while I was parked , I tried to turn the parking brake on and when I switch the car on I get a Parking brake not fully release error.
Roadside assisstance come and the guy thinks is a software glitch. Resets the parking brake and before driving away , there`s no parking brake error or warning but a SRS airbag service required warning came on. The guy from roadside assistance had a look and saw the error and after 2 minutes there were no error about the airbag. The warning with airbag still pop up while driving. I was told is either a software glitch or ECU unit. Fortunately when i bought the car I also got RAC extended warranty.
I was thinking maybe the battery.
Did anybody had this issue before?

Sorry for the long post

I went to the Volvo dealer and it was the brake harness and a software update.
