Hi All, my car has a recurring fault with exactly the same symptoms each time, when driving, the steering wheel starts shaking then the car loses power, next the Check Engine Light and the Electronic Power Control Light comes on, then White or Blue smoke comes out of the exhaust and their is a strong smell of petrol. Has anybody any idea what could be wrong? (The car is a 2011 A5 2.0 litre Tfsi petrol). Thanks.
