Hallo !
Translation with google translate.
Octavia 1.8 TSI, BZB, 2008, 118.00 km stock engine.
I can not solve the problem.
I changed the chain, I thought it was from the chain but it is not.
We noticed a strange noise that we perceived at 2,500 rpm up to 3,000 (the newer one is also heard when I accelerate, randomly). I checked several times and tried to register. Unfortunately, the recording is heard only in the first part of the video, in reality the noise is much more pronounced.
I did not notice anything special with the stationary car, I would say it is rather the task. The car goes well, the diagnosis gives me a fault in the manifold intake.
I'm just afraid to go with her, no one finds the problem.
Pay attention to the first part of the video when it exceeds 2,500 rpm.
In the last days the noise has increased and the mechanics can not figure out where it is.
It's louder in 1st gear or faster accelerating.
Some say it would be vibrations from the acceleration flap others say the gasoline pump, others as the problem in the engine, etc.
