I describe the process here, although don't show it ... I just notice I say A pillar...but it is B You are not going to set the Air Bag off, its up in the headliner not in the Pillar. Here's Steve's pic of where to stuff foam first...notice it really is a Trumped Bell...super silly not to block this in the factory. The Superb III Sills are big and really resonant too. Soaking up all sorts of outside noise and channeling it into the cabin through this area. Rap them with your knuckle along their length, its quite surprising how thin and undamped this metal is.

Start here ... the floor that is visible when you remove the boot wheel cover and wheel, of course. Probably the most dramatic change you can possibly do in a Superb III Its something you can easily do yourself too. You just need to buy some Butyl Sheets. The B pillar is probably #2 on my list of dramatic changes...nothing like the boot floor, but significant as sound is piped up the pillar to exit around your head and the seatbelt. Anyhow I recommend reading the entire Noise Reduction thread I linked above.

Just to clarify ... cabin noise is mainly mechanical vibrations from the tyres making its way into the suspension and then into the bodywork, which re-radiates into the cabin. Hence why dampening the panels from the inside can have an impact. I don't believe the tyre-to-air-to-wheel-arch is a particularly major path for noise. Example. The sill channel below the doors, would pick up more noise and vibrations and does re-radiate directly into the cabin up the B pillar. And then there is wind noise of course.

The main topic on all this is here FWIW https://www.briskoda.net/forums/topic/449490-noise-insulation/ Wheel arches are far less important than doing the boot floor and sides with sound deadening material. This area acts like a big speaker driver. I have done the front and rear wheel arches and sprayed the rear felt covers with a rubber dip compound to increase their density and durability. I am not convinced much noise gets into the car directly from the wheel arches. Its mainly sympathetic vibrations in the panels in other parts of the car from mechanical vibrations. https://www.youtube.com/watch?v=676P7bIV0Gg

Quick. Throw a piston rod.

I had been meaning to come back and ask

Welcome to the thinking man's Passat

5) If you can remove the front door cards, the rear are 5x easier ... I did it a few weeks ago ...

Thanks for the update, so it was a vibration isolation failure? I assume the grommet is for NVH?

There is a secondary (low pressure) electrical oil pump to oil around the turbo bearings to prevent sludging in there and premature turbo bearing failure. Normal. Not sure why it pulses tho. I think they have some strange algorithm to maximize low-duty cycle cooling.

Are you sure its not just settings? If they disconnected the battery you may have lost them.

I have them and use them frequently, anticipating steep hills etc. Skodas calibration always lugs the engine too much for my tastes.

This could be normal. What is the ambient air temp and humidity? Are you in Singapore? Generally the fan should cut in and out with the compressor. So if it never does anything other than run at 100% and is making a lot of noise doing so, and you don't live in the tropics or Dubai, it doesn't sound normal.

You mean the one under the bonnet. Radiator fan? No that should not run all the time. It's electric no?

Concrete?! Luxury... These are the surfaces I am talking about not concrete or Asphalt (left side) but Chip Seal (right side). This stuff causes a roar inside the cabin.

Then you don't have coarse chip roads The car itself is quiet. Although a little more wind noise than some. Its the mechanical vibrations and reverberations from the tyres through the suspension and then into the frame and so cabin on noisy tarmac.

Thanks for the update. So Item [17]? So this is a vacuum or pressure leak? Could be a hole in a diaphragm or o'ring leak indeed.

After seeing so many people doing it the wrong way, I decided to make my own video

Settings > Screen > Switch off screen (in 10 seconds) - Enable/disable the automatic power off function This option does not seem to be remembered. Any ideas?

For those with an MY19 Hatch and said glass fitted, is this also applied to the rear hatch window? If so, is it the same density as the rear-side windows? The configurator is not exactly clear (no pun intended )
