I've now owned my 2019 Octavia 1.5tsi se dsg for around a month now, I've picked up on a rattle/resonance sound, seems to be coming from my front dash area, somewhere near to my dash clocks or maybe slightly to the right of them. The noise seems to occur once my car is fully warmed up, between 20mph & 40mph, but can sometimes hear it above those speeds. The noise does not occur when the car is stationary & I rev it up. It occurs when I'm slowly accelerating up through the rev range, not usually above 4k. I've checked all the obvious stuff, not easy when you are driving. Not the sunglasses holder, doesn't seem to be coming from the heater vents or display screen area.. Not sure if mine has the sound amplifier? Any ideas? I have an extended warranty that doesn't cover rattles. 

I think I'm doing well, as this is the only slight annoyance that I have with my car, otherwise I'm finding it an excellent drive & surprisingly very good on fuel.

I have a 2019 1.6 dsg diesel with the same noise. I look forward to someone offering some advice, I have been trying to find the source for a couple of years!

Interesting, mine is more prevalent during slow acceleration, starts at around 20 mph, then stops, then starts up again at around 40 mph, then it's more of a back ground noise as my speed increases above that. It doesn't do it at all for the first few miles from a cold start, either. I'd probably describe it as maybe the sound of a nut/washer resonating together at certain speeds. Pure guess mind, not a difficult job to take the dash clocks out, but I wouldn't really know what I'd be looking for, especially when my car was stationary. 

If I ever do get to the bottom of it, I'll post it on here, although I'm not actively looking at the moment. I have a couple of other rattles, but this one is the main one I'd like to find, other's I'm happy to put up with. As my car was ex mobility I expect the noise has been there from new, my car has only covered 22k up to now. 

On a side note, what mpg have you averaged long term from your 1.6d? I've averaged 48.9mpg over the last month on E10 fuel, I can get up to 60 mpg on longer runs. I'm pleasantly surprised by this, I consider myself to be a fugal driver, though.

Just checked under the scuttle panel by removing the 4 front clips, access tight, obviously without removing the wiper arms, but doesn't seem to be an amplifier in there, maybe due to being the SE spec?

Phoenixboy, interestingly my long term average is very similar, on longer runs often over 60 and on a few occasions got 70 (according to the computer not a tank fill to fill)

I've also owned a number of diesel cars within the past, although my current petrol Skoda seems better on fuel than my previous petrol car with similar bhp. 

 

I have a dash rattle from a similar area but is more limited to revs. From 1800-2100 rpm I have a resonance/rattle. I thought it was my drivers side speaker but after a bit of testing it doesn't make sense. I've yet to pull the windscreen cowling off and check the sound amplifier, I appreciate it can't be this for you however.

 

One common issue that's popped up from searching the forum is fuel hoses which rattle in their holder underneath the car. This was solved with some sticky foam pads.

The resonance noise I experience can also be heard at the similar rev range as yours, although I'd be in 5th gear at those revs for the noise to occur (mine being an dsg). 

My car needs to be fully warmed up before I can hear the rattle. I have other rattles, but this one annoys me the most. Although I've not owned a car yet that's had none.

Were the hoses related to petrol or diesel cars?

Thanks.

Not sure on petrol/diesel specific but here's a fix thread.

Thanks for posting the info, once I've checked mine I'll post the result. Sounds very relevant as mine seems very throttle pedal related, think it's probably been there from factory.

It's something I've been meaning to check myself to be honest, I'd be interested to see if it's still an issue seeing as you have a much later vehicle. Any little fixes to improve niggles is always a good thing.

It looks like I'm going to have to get both of my trolley jacks out and my axle stands to make fully sure that my car was lifted securely before I go under to check. This is where a lift would have come in handy. Thought my days of crawling under cars was over😂Once I've got around to checking it & post results.

I've got to the point that unless I am REALLY broke I get most things done by a garage. Something as basic as this though I'll do myself. Luckily my dad has a pit in his garage which will make things much easier.

Yes my car has just been serviced and has a full mot, owned it for just over a month now. If it had been due for a service or an mot, I'd of asked my garage to have had a look. 

Don't think I'd take it in for just that, considering I'm not even sure it'll resolve it. 

I'm going to have a look today, I'll post a pick. 

I've done a lot of servicing and maintenance myself on previous cars, but I'm at the point where in wrecks me now crawling under cars, main reason I try to avoid it. 

I also have a set of homemade low rise ramps, which would be the easiest way of getting the car up off the ground, but not sure if they'd give me enough lift. Reason I was thinking about trolley jacks and axle stands.

I've just checked them, I'm not convinced it was the bracket, mine was as solid as a rock,no movement. Neither could I test it stationary, as my car has to be on the move for the nose to occur.

Very easy to access though, from the drivers side rear, fortunately my low rise ramps were perfect for the job, although you could see and reach them without having to raise the car.

Sorry it wasn't that but was worth a look!

I also had my son rev the car at certain rev ranges, no rattle at all from these. Seems more frontal dash area to me, maybe slightly to the right hand side of the dash clock area. Hard to tell, really. Was worth a try. I did also get my son to hold the revs at 1800rpm & I had a listen within the engine bay, the engine had a slight resonance to it at that speed. So I think this is about all i can think of for now, if I do ever get to the bottom of it I'll let you know. As I've said previously I think the noise has been there from new. Something I can live with for now.

Edited 3 October, 20223 yr by Phoenixboy

Just for further clarification, the resonance noise I'm experiencing only occurs between 1700 & 1800 rpm on a constant basis, sometimes not there from a cold start and is harder to pick up on when the car is stationary. 

Now I've had more time to look into it.
