Hi,

Does the noise emission also fall under the vehicle's approval certificate (ABE)?

Best regards,

Jan.

This is not good; pedestrian safety suffers as a result, and the small crumple zone between the engine and hood is eliminated.

Well, that's something people can argue about.

Without the engine cover, the hood absorbs energy for a longer period and to a greater extent due to its "soft" deformation, as it can crumple freely all the way down to the engine.
-> When the crash occurs and the hood briefly touches the engine block, the pedestrian is likely to fare better than if there were a cover on the engine.

@Jan: Yes, the noise level is part of the approval documentation (ABE).
But whether it has such little insulation that the car is already too loud without a cover .
Then every instance of loud exhaust noises, squealing brakes, and turning up the radio would also make the car "illegal."

Nope, the impact energy has to be absorbed or dissipated somewhere. A practically flat hood absorbs very little energy; that energy then has to be absorbed by the well-padded cover over the engine (as much as possible) before it reaches the hard engine block.

Please read the common safety regulations/requirements for vehicle crashes; then you will see that I am not telling nonsense.

How about the radical solution:
Once you remove the cover and its brackets, you have unrestricted access to the engine.


Well, just look HERE .

The cover isn't entirely useless, as you can see from the pattern of contamination.
'That's about 200 kilometers driven on the A7 highway, with a fuel consumption of 8.7 liters.'


what bothers me is the noise outside... it even drowns out my ALH, and that's even louder than the old MB-100 .

Do you have a link for that?

No, but there's a roughly 1200-page comprehensive textbook on automotive engineering by Vieweg called 'Kraftfahrzeugtechnik.'

Oh dear... but what surprises me is:
The technical inspection agency (TÜV) has never commented on the missing cover, either for my car or my wife's, not once with the G3 (twice) nor with the Ibiza (once).

Do they not know about the crash behavior? Because if they did, they would be much more aggressive when it comes to pedestrian safety and other related issues.

Oh, TÜV... the people working there seem to lose their IQ when it comes to the deeper, wider, harder, louder faction, and in my opinion, they no longer have the 'insight' for something like that.

While working with Mercedes' internal parts catalog ('AKTE'), I once read that the operating permit (ABE) for passenger cars is invalidated if the engine cover is missing.

Okay, it's true: The engine cover on my ex-ALH or AWX is just a toy compared to the 'plastic boxes' from Mercedes-Benz. Taking it off annoys me, but for pedestrian safety, I keep the crumple zone completely intact.

@ Gremlin

"I've taped up a lot of holes, and most of the major leaks are stopped. I rely on a fantastic fabric tape for that. I haven't been able to control the small amount of fluid that comes through the radiator, which always ends up dripping onto the oil filter housing... well, otherwise, it's relatively verschandeln underneath."

It's amazing how quickly you can delve into off-topic areas (related to the initial topic).

But don't let that stop you; I also participated .

Regarding the topic:

I just discovered that ASZ and ARL models have a throttle valve installed, which is actuated by a third vacuum valve (N239) located on the left side of the intake manifold. The valve is controlled by a "vacuum actuator for intake manifold switching."

Could this be the part we're looking for?

'All TDIs have this shut-off valve...'

It's in the AGR valve housing...
In the image, above the AGR (Advanced Gas-cooled Reactor) canister, there's a small black component. It is controlled by N239.

Okay .

But why the term "switching" has to be used for a shut-off valve is probably only known to the demigods at WOB .

Well... pipe open or pipe closed... there's nothing in between.
so, a hard switchover .
