I have a Mark 5, 1.6 FSI 2007. On starting the car from cold the engine shakes and makes a slight tapping noise when reved. This lasts for about 5 mins and then the car is fine- it feels like its running on 3 cylinders....then fine after 5 mins, any idea what the problem could be?
The car has been regularly serviced by VW and is not due for a service......
