Dear viewer,

In this video I am giving you an in-depth guide on how to remove the intake manifold, delete the flaps and do a basic carbon cleaning on a 5.2 V10 FSI engine, which was put in the Audi S6 C6 generation and the Audi S8 D3 generation.

The flaps breaking is quite common on this engine. It is not a matter of whether the torque flaps will break, but rather when that is going to happen. Considering that these cars are becoming about 15 years old now, it is pretty much guaranteed that the flaps will be broken if the previous owner of the vehicle didn't replace the entire intake manifold. Yes, the entire intake manifold needs to be replaced if you want the repair done properly, as the flaps are integrated in it. As the intake manifold is quite expensive and also not a readily available part in all regions, many, such as myself, have decided to take it upon themselves and simply remove / delete these torque flaps.

The deletion of the upper intake torque flaps not only will resolve a quite annoying rattling issues which may occur when the flaps break apart inside the manifold, it might also save your engine. The thing is that usually when the flaps go bad, little bits and pieces of plastic come flying inside the intake, something which as you can imagine isn't good for your engine, because a tiny bit of plastic falling in the engine cylinder can irreversibly damage the engine. If this happens, considering the cost of a new engine, the car usually totaled.

When doing an intake manifold flap delete, this is also a perfect occasion for a quick and dirty engine carbon cleaning. FSI engines use direct injection. As such the valves do not get sprayed with fuel and cleaned in the process. This results in carbon build up, which if left unchecked will eventually result in rough idle, CEL being on and also in some occasions cause random misfires, especially when the engine is cold.

Additionally, this video also shows how to check whether the throttle bodies are working properly, and also shows how to remove the PCV valve itself.

As always, if you have any questions please leave a comment in the comment section below and I will do my best to answer them. If you liked the video and found it helpful please leave a like and consider subscribing. Thanks!
