I did some research on this topic — the Russians are the best at it, especially on the drive2.ru forum. Newer Octavia 3 models mostly have speakers with the part number 5E0035411J. They have a large magnet compared to older series and sound good. However, they have an issue with the magnet shifting or coming off. When the magnet moves slightly, it presses against the voice coil, and the speaker can no longer play, or the coil scrapes against the magnet, producing a crackling noise. This seems to be a common problem with this speaker series. If the magnet shifts or falls off, a special centering tool is required to realign it. It can be fixed, but it’s difficult. I didn’t want to buy aftermarket speakers (Hertz, Pioneer, Ground Zero, etc.) because I believe that the cheaper series without an amplifier wouldn’t sound any better, and I’d have a hard time with installation, spacers, adapters, and so on. I ordered a used pair of 5E0035411J speakers for my Škoda, €40 per pair. I applied Bison two-component epoxy adhesive around the magnet, and I hope it can no longer shift. The sound is back to its usual good quality — there’s a nice amount of bass, nothing premium, but perfectly satisfactory for a car

Hi everyone, I drive a Škoda Octavia Mk3 and have generally been quite happy with the factory audio system – it's not high-end, but it delivers decent sound for everyday use. Recently, however, my front door speakers started failing. The left one crackles badly, and on the right side, only the tweeter still works. No idea how it happened – maybe the kids played something too loud... Now I’m considering replacing the OEM speakers with something like these: 🔗 Hertz Uno K 165 – 300W Component Speakers On paper, they look good: 93.5 dB sensitivity, decent power handling, and Hertz is generally a respected brand. My question is: Would these offer a noticeable improvement over the factory speakers? Or would it make more sense to simply source used OEM replacements? The originals have basic paper cones and small neodymium magnets – they look underwhelming, but surprisingly, they sound pretty good, with decent bass response too. Has anyone here replaced the stock speakers in a newer Octavia (Mk3 or Mk4)? I'd really appreciate any feedback or recommendations based on your experience. Thanks in advance!

What do you think the problem is, brake pads or brake caliper sliders and rubber sleeves? I was thinking of buying this set https://www.autodoc.co.uk/brembo/14441525 and replacing this.

I don't understand, are you saying that it's normal what I sent in the video, that the brake calipers shake like that? And that the knocking I hear when driving on uneven roads doesn't come from the brake calipers but from the shock absorber struts and mounts?

Check out this video I made today, what do you think? https://vimeo.com/939211854?share=copy Otherwise, there is a knocking sound when I drive over a bumpy road. I'm not sure if it's because of the brakes, but the mechanic checked the entire suspension, arms, silentblocks, sway bars, etc. and says that everything is fine, there is no air anywhere.

In Friday I picked up the car. They say the repair cost 1,100 euros, everything was done, the engine head was machined, all rocker arms and hydraulic lifters were replaced, as well as camshafts. The repair was covered by the car dealership where I bought the car, they turned out to be fair and honest! These days, weeks, I checked the car wherever I could, CarVertical, I also found a Belarusian website KA.BY for 1.2 euros, which gives you the mileage of the car based on the VIN number and then you can request an extended report. Everything indicates that the mileage is genuine, 161,000 km. Also, the vehicle is very well maintained. I have no idea what happened, when I bought the vehicle, a major service was done even though it has higher mileage, they say it was done just as a precaution because it doesn't cost them much, and they provide a warranty on the engine, so they want to be more confident. Maybe the mechanic messed up something then, or maybe the service was done because of some accident that wasn't adequately repaired, I don't know, that will remain a mystery. In addition, the injectors have been checked, they're excellent. Nearly 2 weeks of great nervousness, stress, negotiations, they're behind me now, may it not happen again. Moving on, I hope the quality of Skoda will now show... Thanks to everyone who participated in the discussion and commented, every comment was useful in its own way!

The engine head is currently at the machining service, they told me they will handle it with maximum quality. They also advised me to consult with the mechanic to replace ALL valve lifters and rocker arms, not just the damaged ones, even if I have to pay extra for it. I called the mechanic, he assured me that he will indeed replace all valve lifters and rocker arms, as well as camshafts, he won't risk anything.

That's exactly what I was telling you about.

Or, a more realistic scenario could be the following: The car had damage to the cylinder head, such as a belt breakage, etc. The car dealership imported it and repaired the cylinder head, along with performing a major service. BUT, they didn't pay attention to the camshafts' lobes, which can slip/rotate around their axis. What happened next is what happened...

Since a major service was done just before I bought the car, I'm almost certain that the engine timing wasn't set properly, meaning that the engine and the engine head weren't synchronized. That's probably why the car behaved strangely at low revs. Since I hadn't driven a car with this 1.6 TDI engine before, I thought it was normal for it and simply required, for example, shifting back to third gear when driving at 50 km/h. That's why the valve rockers broke. The mechanic probably won't admit to it, but I hope the engine head will be serviced properly this time and that the engine timing will be set correctly.

ChatGPT 3. I bought the car used, at a car dealership. Everything seemed fine, the car is very well-preserved and there were no signs of any problems with the engine head. The only thing I noticed is that it doesn't perform well at low revs, for example, if driving at 50 km/h in fourth gear, it feels like the engine has significant vibrations and makes a strange noise. Otherwise, it ran smoothly and pulled well. Three weeks have passed since the purchase and suddenly it broke down, during light city driving, the engine started running on 3 cylinders, shaking violently and barely moving. My mechanic determined that there is no compression on the third cylinder. So, I returned the car to the seller because I received a warranty on the engine from them. At their mechanic's, I saw broken valve lifters. Now they need to solve the problem and fix the breakdown. I hope they'll do it properly.

I don't know what caused the rockers to break. I doubt that the engine had a problem before and that the seller repaired it badly. I can't check anything because the vehicle is being serviced by the dealer's mechanic.

Of course the camshafts rotate, you didn't understand me (translator). In the case of the 1.6 tdi engine, the cams are pulled onto the shaft, it is not cast from one piece. It can happen that the cam ends a little or rotates around the shaft.
