Hi, I have an Audi A4, B8, Multitronic, 2.0 TDI and it has developed some symptoms: - increased fuel consumption (poor mpg) - slight engine shaking but become worse when I switch off the engine (the whole car shakes a lot more on the moment between pressing the key to switch off until the engine dies completely) - a while back I've noticed that for the first time on the day the car won't start at first attempt but at the second. Now, it will not start after 3-5 attempts. I press the key, the engine cranks but just when it's about to fire, it dies like something it's not there, like the fuel just ran out. When it won't start, the cranking time is the same as when it does start, the car does not crank longer. It will happen only when I use the car for the first time on that day after which the car will start at first attempt perfectly fine every time until next day. Battery is new/good and it's summer at the moment. There are no fault codes on VCDS. However, after my research, I think there is an issue with either MAF sensor or EGR (or both). I have attached 2 screenshots from VCDS with engine at idle, do these values look abnormal? Thank you, George

Hello My engine vibrates really bad only when it gets warm from 50C to 90C shakes can be felt inside the car, rmp hoping up and down, mpg decreases significantly, fuel smell and white smoke from exhaust (only when it's shaking). When it's cold or warmed up to 90C it's alright. Rmp steady, starts easy and everything works as it should. No faults on dash and computer didn't read any faults either. Why it's only shakes from 50C to 90C? Can someone help diagnose the problem I'm having?
