I listen an engine clicking noise on Audi A4 coming from combustion
Finally, if you think that this clicking noise is linked to the combustion of your engine, there are three plausible triggers of it. Verify the state of your glow plugs which if worn can hinder the proper combustion of the fuel mixture. Then, your timing belt may be shifted and may poorly control the timing of the various engine parts to promote good combustion. And finally, the most classic reason, comes from your injection, which is either blocked or one or more injectors is injured.

Hissing noise / engine friction Audi A4
Engine noise Audi A4 close to a bearing
If it is close to a squeaking noise you may have one of the bearings of your engine accessory parts that are reached. So examine the state and try to locate the exact source of this noise by positioning someone at the engine at idle, and if this noise is more likely to happen in high rpm, accelerate and position someone at the engine block to determine the region of origin of the noise.

Engine noise Audi A4 close to a friction
In case that you listen a motor noise on your Audi A4, and, that this noise is close to a friction, it is likely that one of your belts or one of the parts that triggers it is the origin of your problems.Often, we will start to listen a motor noise on Audi A4, close to a friction when one of the belts is worn out or when one of the related parts like your alternator, or your tensioner roller is the trouble. So think about to examine their state and go to your motor mechanic to change the components in question. If you have been able to target the noise as coming from the belts and you want more details about it, take a look at this content page on belt noise on Audi A4 for a complete guide.
Metal motor noise Audi A4

Finally, the second possibility is that your silent engine blocks or rubber mounts may be dead. This triggers a metallic noise each time your engine moves, either because of a change of pace (acceleration or braking) or, when you drive on roads in poor state. Verify the state of your silentblocks and change them if necessary.
