Engine Knocking/Tack Tack

[Fahrzeugtechnik]

Hello guys,

I have the following problem:

When the vehicle is accelerating normally and from around 1200 rpm to 2800 rpm this metallic rattle occurs. (tack tack tack tack)

For it it sounds as if the noises come from the area of ​​the oil pan.
The noise can also be heard when starting under load and in R, D.1,2,3,4,5,6,7 while driving.

It's not when the car is in N (neutral) and I rev up the engine. I can only provoke the noise while standing if I put in D, press the brake and accelerate at the same time.

It also seems to me that it only occurs when the car has a certain temperature.

No sound can be heard at full throttle. The car is otherwise very good. (MHD Stage 2).

The action with the strained exhaust camshaft has already been taken. (Realigned and screwed in with the correct torque).
Additional weight on the air conditioning line was screwed on.
All heat plates checked.
All exhaust gaskets made new.
All parts on the underbody checked.

The following parts are installed:

NGK 97506
5W-40 Ravenol Oil
M-Perfomance exhaust
Catless OEM downpipes
Silicon charge pipes
Alu boost pipe
KN drop in air filter


Sorry for my bad English :-)

Thanks guys
