Hello, I have a 1.6fsi which I have just bought from a dealer. After two days the engine light came on and the car went into limp home mode and idled very rough.
Took it back and it was a cam shaft sensor fault which they replaced with a genuine Audi part, drove it home and light came on again, cam shaft fault.
They checked the wiring back to the ecu, all fine so they re placed the ecu, again drove home light back on cam shaft fault.
This is the problem when the car is cold in the morning it drives perfect, but has you get into traffic and the engine heats up the engine starts to loose power the longer in traffic the worse it gets, it revs out perfect no miss fire only accasionally not wanting to rev past 4500. The engine feels flat no real power low down and as it revs out there is no build up of horse power through the Rev range. If you are on the motor way in 5th at 60 will not accelerate and pull very slowly. It also struggles to accelerate up sleep hills with lack of power but, no miss fire.
Anyone else had this problem please help, Robert
