I had a new exhaust fitted at the weekend, when i picked up the car I noticed that the EAS was set to the access level. As I drove off I realized that the indicator was flashing but the EAS was not rising. Got home (15 Min drive) and the same situation. This morning there is no air in the airbags at all and the car is on its bumpers. There is no faullt displayed, and also there is no noise...it sounds obvious that the garage have disturbed something, any ideas?
