Yes I took the car out on a variety of road surfaces for around half an hour. Sound was as normal at all times. Previously the booming noise was there driving above 20mph at all times. I was keen on supplying some pics as I hadn’t actually seen any fixes for the rear boot stops for the estate only the hatch.

Pics as promised

Oh I forget to add, I almost never go past half way on the fuel level, for some reason last week I really couldn’t be bothered to go to the petrol station to fill up resulting in my fuel level being at approx 1/3 full when my booming problems started...coincidence??? possibly may have something to do with an emptier fuel tank than normal?? You can make your own mind up on that one. anyway I hope this may help some people with the same problems I had. all the best

Boomy noise FIXED in my Octavia mk3 estate. I’m not really one for posting on forums and such like but I’d just like to share my experience with others so they could try the fix I have done to cure the boomy sound in the rear of my Octavia 2.0 diesel estate. On way home from work fri afternoon, just joined m1 got up to approx 75-80, an almighty pressure built up in whole of cabin, thought my ear drums were about to explode. Initially thought it was 1.0L Fiesta boy racer in front with big exhaust, but after I had passed him the noise was still there. Sounding like a split exhaust down pipe I carefully nursed car home below 70 where the sound subsided. Once off m1 in stop start traffic with windows down I could hear no noise......strange. Once I had got home I got a brand new tea towel off the missus and proceeded to hold it over the exhaust while engine running to see if exhaust was blowing. To my amazement there were no leaks from the exhaust. Now I was really scratching my head. Then I proceeded to search this forum, and to my horror I found this thread at 60 pages long!! All relating to people’s fixes wether it be suspension, tyres, rubber bumper stops etc. Before trying any of these fixes I drove the car for a bit and just like most of people are saying, it’s a boomy noise at any speed, and also the pressure problem like the rear windows are down. Anyway what fixed it for me was.... ....cleaned boot in spare tyre well thoroughly to ensure no d debris rattling about ....laid 2x 4mm carpet underlay under spare tyre and securely tightened it back down ....cut 2x 4mm underlay and laid it under the existing boot liner in between the spare wheel .... cut some 4mm rubber strips and positioned them behind the boot bumper stops ....also put some underlay behind the rear plastic boot trim near where the latch is after all this I took the car out and it was back to being as quiet as normal, minus the road noise. i promise pics will soon follow. hope this helps a few people out. Just to refresh, I’ve had my Octavia mk3 estate, se trim, dsg, 150bhp for approx 3yrs now without much problem, apart from the fuel line rattle, (now sorted), I was so relieved when these few fixes actually worked for me, and my car is now back to normal.
