Hello Abeer, Cutting into this thread, I begin to think that the wheel alignment alteration may well represent the point of change of this car’s handling, unless that chronology doesn’t stack up. ‘Tyres not changed ..’ What brand of tyres are on each axle? Is the amount of tread even on both tyres on each axle? What tyre pressures are you running, and have these been checked (when cold) against Audi’s recommended pressures? Be aware, the increase in running pressures ( over cold set) will not be insignificant in these high ambient temperatures. Regards, Gareth.
