I have Octavia 1.6 deisel Elegance Estate with 24,000 miles and have the car for 8 months now. First noticed the booming / low frequency rumble 6 months ago. Its been into 2 different dealerships for a total of 6 visits. Shocks replaced, rear tyres changed, boot striker plate and buffers changed and its still not corrected. Most recent dealership say they've now compared it to two other cars of same spec and they also have the noise. This has all gone to Skoda technical who have responded with "this is production standard". A raised a complaint and the response (only by voicemail - nothing in writing replying to my email complaint) was "it is production standard". I have recorded the sound using the smartphone app "spectrumanalyze" and compared it to my other family car (a 5 year old toyota yarris) and this proves there is much more low frequency noise driving the Skoda. I will try to upload the results from the app in a separate post to this forum. Meanwhile, my advice to potential buyers of octavias is to have an extensive test drive (at least an hour) and travel on rough A and B roads at 40mph-60mph to check whether the rumbling is acceptable to you. For the rest of us stuck with the problem - I have the following ideas: * We agree on a a social media strategy to raise awareness of this higher? * We agree a physical protest (parking out side dealerships on busy weekend sales days with poster in our windscreen saying "DON'T BUY ONE OF THESE!" ?
