I had similar on my Octavia vRS - it was the brake caliper sticking, only found when it got much worse

Forgot to ask, how could one test for that?

Hi,

Do you have more news?

These people from the dealer, they just keep pushing things. They saw that the car has a problem but they just don´t do a thing. Amazing. That is why I will never buy a german car again. I will go back to Toyotas or Hondas. The experience I have with these brands is that they don´t try to fool the customer. They like to show they are a reliable brand, so they try to make the customer happy. 

If I were you, I would go there again and make them come up with a plan to solve the problem.

My car has a problem with the front windows buttons. Sometimes they fail. I am complaining since factory warranty but they never solved it. Now that the factory warranty is over, and the extension warranty is activated, and there is a company paying for the service and parts, they say they will replace the buttons. No questions asked. These guys... I mean, they don´t deserve to have customers. What a shame.

Sticking brakes should be easy to check with the wheel off the ground and spinning - if it isn't free then there some sticking

 

A driveshaft CV Joint with early wear can cause vibration while turning at high speed.  The usual test is to put the cars steering on hard lock and drive in circles slowly in first gear in each direction. If you hear a bonking or clicking noise then it is usually the CV joint.

Hello fellow Superb owners,

My 2017 2.0 TDI 150 manual Superb estate has been having an issue with vibrations that I can't figure out... Lately I seem to feel a lot of engine vibration through the steering when under heavy-ish load but since this comes mostly at higher speeds I took it to get the wheels balanced, steering aligned and tires rotated back to front. The next day I drove a long distance and got a little enthusiastic on the highway (and also wanted to check for the vibration) and was surprised to see that there was a lot of vibration coming from what seemed like the front right side. I could feel it somewhat in the steering (but nothing like when wheels are out of balance) but my wife complained that she felt it quite a lot (left hand drive). This happened at speeds of ~140 km/h and higher but mostly under heavier engine load AND turning right (when the weight is lifted from the right side). In fact, on a straight downhill I took the car to 180 km/h and it was super stable, so the issue is somehow related to engine load and right cornering, as I don't really notice it otherwise in contiguous stretches of highway. I have driven fast before in the same highway, about 8 months or so ago, and the car was super fine. One thing I also noticed, but possible totally unrelated, is that I hear a loud clicking from the front end, mostly when changing from reversing to driving forward. This noise was not there when I got the car, only for the last 3-4 months.

The car is still under warranty but I don't know if this issue could be covered, whatever it may be. I never hit any pothole or sidewalk or anything like that that could damage a wheel/rim (apart from the "normal" road unevenness, sewer covers, etc.), so I don't suspect damage. What then could this due to be in such a new car?

Dear Sir, Is there a solution to your problem? I have the same problem in a 2020 Skoda Superb 3 Combi.
Thanks!
