An update on this. The latest sound clip i put on here has now been solved. The alternator clutch pulley was replaced and I am told the noise has now gone completely. Total cost of £99. I'm yet to pick up the car, but i'll update later whether or not it is fixed!

Seems like a bargain to me. Lovely looking car! Best of luck with the sale!

I think you're probably right, best to keep a car you know than to change for something unknown! Best of luck with it

You are well into new DMF territory then! I believe they are worse when cold. I'm sure i've seen a few posts of people saying that the rattles got better towards the end of the life of the DMF for some reason. If you have the funds and are looking at keeping the car going, I'd say it is due a new one. Or at least get a specialist to give a proper opinion.

What mileage is your car on? A DMF will wear out eventually, so if you are past 90-100k miles, i'd say it is no surprise.

Possibly, hard to tell with the shaky video. It seems like a DMF failing isn't a noise you can mistake! Unless it gets a lot worse than that, I wouldn't worry.

Decided to hold off on the DMF until it becomes more obvious. However, I do have another issue (identical to the issue my Kia Sorento also has) a strange creaking noise from the alternator area. I'll attach a sound clip, it does this on and off at idle. Also makes a similar noise when steering, but that's probably different! Record114_skoda.mp3 Record113_skoda.mp3

Also, I paid £2500 for the car in July, it had a new turbo straight away when I got it. So if I replace the DMF (assuming it is time) and the cambelt + water pump + aux belt, is it sensible to assume the car should be set for a good while? It had a DSG oil change in July and I'll give it another oil service when the work is done because I've done 9k miles on the current oil.

The recording I uploaded is like yours? It is due a cambelt and water pump as well... ouch!

That does sound different to mine... However, can you hear the metallicy rattle a second or two into the sound clip I put on? Sounds a bit like a tumble drier

So when investigating an odd sound from the aux belt, I noticed that from under the car you can hear a weird rattle noise, like something is moving around almost. Can't hear anything from inside the car as far as I can tell, with the door open, sat in the driver's seat it can be heard if it is quiet outside. Seems to only be in neutral or park, however it may be that the slight vibration when in park or reverse masks the noise. I'll attach a sound clip, it is hard to make out, but right at the start seems to show the noise the best. The car drives fine as far as I'm aware, I've done 10k miles in it in the last 6 months and haven't noticed any change at all. Car is just under 100k miles. Could this be the DMF failing, or is the PD engine just a bit rattly? The sound seems to be coming from behind the engine, when looking at it from the front. Record112.mp3

Could the belt noise and the clicking noise be completely unrelated? The belt noise seems to have gone now. Just got to figure out the clicking noise! Just to add, on start up is does this clicking noise for a second as well, it seems. Another thing. This noise is also there at idle. Not sure if it is just the usual engine noise, sounds a bit like something loose rattling? Hope the audio files play! In the 112 audio file, that is the odd noise at idle. It is hard to hear as it isn't that loud, but at the start in the background it is most obvious Record-112_medium_quality Record-00111_medium_quality

Managed to reproduce the creaking sound. It is when you turn the steering wheel, weirdly? I'll attach a sound file, not sure if it'll show up, but should do. Record-00111 Probably more like a clicking sound if anything. I've only noticed is when the car is warm.

I figured it would be harmless?! I'd read in a few places of people using plain old wd40 for it. Tonight's job will be to spray it with plain water then. The fact that the noise went away when sprayed (even if I used the wrong thing.. oops!), does that suggest a part is at fault? I sprayed the alternator clutch pulley first and that is when the noise pretty much stopped. I suppose a belt and pulley replacement is about £130 all in, so not too bad for some peace of mind.

So I've sprayed the pulley + belt with wd40 silicone lubricant spray and the background hissing sound went away immediately. I can't get it to reproduce the weird creaking sound now, but will keep trying. I revved the engine to 2k RPM and shut the engine off. All I got was a sound of air releasing, I assume from the turbo. No odd noises other than that. One odd thing is, my radiator has a wet patch on it and behind it and in front of it on the bumper where the bonnet shuts there is a small patch of dark oil. Strange? I'll attach some shots of it lets me, if not I'll try and downgrade the quality and add them. From the photos you can see the bonnet latch near the radiator has oil on top of it, so does the edge of the engine cover. Could this have been just spilt oil when the garage topped it up when they did an oil change in September? Also, if the tensioner pulley is the bit that is diagonally backwards from the clutch pulley, then that doesn't have excessive movement, it moves maybe a very small amount each way, when the engine is running.

Sorry, should've said. The cambelt was last done in 2014 at 36k miles I believe. Nothing since then.

Gotcha. I'll try and get a better recording this evening, may just have to be a mp3 file. Is it worth using some sort of tube against different parts to see if that amplifies any sound?

Are any of the 4 jobs listed above particularly expensive at garage prices?

I have no records of a new belt at any point. I got the car in July with 90,600 miles on it. It now has 99,800 miles on it. I'll check again later, but I think it may be oil on the belt? There seems to be a splatter of oil in that area that has gone onto the bonnet as well. It last had fresh oil in September when it had a new turbo.

Can I do that whilst it is in situ?

Is that common? It is quite a loud creak when it does it

Managed to get a low quality video to upload. This doesn't show the main sound as it wasn't doing it during the duration of time that I filmed! However, there is a slight hissing sound in the background, not sure if that is normal either. VID_20190218_2036450.3gp

Also, I have only just noticed it and the car was cold. I'll keep an eye out when it is warmed up, definitely hasn't done it when warm before today! Just another thought. When you first start it up there is a clattery noise for a second or two.

Here are some pictures of the area. Tried to get a video of the sound, but all I got was a hissing sound of that area, like an air leak almost? Can't upload anywhere near what I wanted to upload due to file size. There seems to be oil around this area too. Splattered onto the bonnet directly above? Can't really show what I'm trying to show with the picture it is letting me upload. Directly below the alternator there is an oily patch and on the pipe below. No oil is left on the ground however.

2005 Octavia has just started making a weird noise. The exact same noise our Kia Sorento has just started making funnily enough. Sounds like something being tightened a bit too much and creaking/clicking. Not constant, but fairly regularly every few seconds or so. The kind of sound like when you would wind up a wind up toy or something and you wind it up past the limit? Looks like it is coming from the alternator area, like with our Kia. Any ideas? We are relying on the Octavia, so it'll need to be sorted asap if it is a big issue.
