tl;dr - The airbox housing isn't attached to the car frame/body - I need a new piece to replace it but don't know the name or part number of it.

 

My Octavia has had a knocking noise issue for a while now - I took it to my local mechanics and they tried a breaker/pry bar out to see if it was any of the bushes etc. with no avail.

 

The other day I was investigating the battery issue I'm having with a friend (battery is dead after sitting for 5-7 days) and noticed that with the bonnet open and the engine starting the air box isn't attached to the car properly and it shakes violently inside the engine bay.

 

I've circled it below in the image - but there should be two screws that go through the plastic of the housing into the body of the car. On my plastic air box the plastic where the screws would go through have come off. So the screws are in the body and the box is not attached at all. I suspect this is what is causing the knocking noise. Does anyone know the part number so I can replace it?

 

I'll get some proper pictures later if it's not clear!

 

Cheers!

Which engine do you have? 

 

This is part of the air intake. On my O2 (1.9 TDI BJB) it was snapped into the front piece of plastic (if I remember it correctly)

 

In another thread here it's listed as 'Air intake':, it also lists a part.no: 1k0805965 But without knowing your type of engine it's pretty hard to provide more details

Hey DJSmiley,

 

Thanks for the response - It's the petrol 2 litre TFSi! Cool I'll have a search for "air intake duct".

 

Here are some pics!

 

Pretty clear the mount has popped of the screw

 

You might try to repair it (instead of replacing it)

 

I think with some epoxy glue or similar you can easly fit a small ring into the remaining piece. Once the glue has dried, its likely you can just use the screw as designed.

 

Maybe you even don't need any glue, just add a ring to the screw to increase its outer diameter so it will hold the plastic piece. There is almost no force on this screw so it should be an easy fix.

Just remove screws on both sides, pop it back in, add a small (penny) washer and place the screws back.

Yeah I was thinking of using a large washer to keep it secured - assumed the plastic part wouldn't be too expensive if I could find it! I'll grab some washers tomorrow and see if that does the trick!

 

Thanks for the help!

 

Edit, can't find many (mostly in China) but the part is called "SLAM PANEL AIR INTAKE DUCT GUIDE": https://www.ebay.co.uk/itm/1K0805971C-Air-Intake-Guide-Inlet-Duct-Fit-for-VW-Volkswagen-Golf-Jetta-Mk5-Mk6/262873528433

A couple of well placed plastic wire ties might do it, drill a couple of small holes and wire tie it up....................
