View Full Version : Rattling on start up

10-15-2014, 02:09 PM
After the car was sat for about 15-30mins.. When I turned the car on I heard a rattle under the bonnet from the engine for a second and disappears.

I turned the car off and tried it again and everything was fine

I then went home and came back to the car 30mins later and the same thing happened. It keeps doing this.

Everytime I leave the car to sit for about half hour or 15mins. Once I turn the car on I hear a rattle. A sort of sound from a cold engine start in the morning.

The car is a 3.0 tdi quattro. Anyone able to help me?

Timing chain guides and oil check valves. Audi really messed up the design of their timing components 2004-07. The 3.2 doesn't suffer as much but still has timing components go around 160k....

Is there a guide on these components?
