good afternoon
i brought a 2018 porsche cayenne 7 months ago. on friday night i stoped at traffic lights and the car would not start again . it wouldn’t even turn over . i got a warning on the dash saying low tyre pressure and another warning saying new tyres detected . had the back two changed 2 days before all this . i now have electric parking break fault and the engine management light is now on . the car won’t even turn over . please help as it’s driving me mad
thanks in advance
