I’ve had my (new to me) Superb for a week and a half and it’s developed a distracting buzz which seems to be coming from the b-pillar area on the drivers side. It makes itself known around 2.5k rpm. Any ideas what it could be or what it is?

I have this too.. it’s very annoying.

 

had my car about a month, is my2018

I have yet to take it to the dealer to confirm or try to fix as it’s very intermittent but I am led to believe it is the fuel pipes under the car resonating up the b pillar.

Others on the forum seem to have had success with the dealer making some adjustments and perhaps a diy fix. Look at the noise and rattles type threads.

 

 

 

 

 

I had this on a b7 Passat, turned out it was fuel lines resonating. Not sure if that is the case here. One of the easiest things you can do is remove the b pillar trim and apply in that area some closed cell foam and dynamat. That made quite a dramatic improvement in my car.

I thought mine was fixed during service (gone when I drove back and gone for a few weeks..) but it's back now. 

 

Quite annoying but my fix is drive at a speed that it doesn't resonate. That means under 70 or over 80 for me. Very convenient lol.

Fuel lines was my first thought too.  I have this same issue and have since new; despite showing the dealer in person and in a video they simply said 'no fault found' on the work sheet....

 

On an Octavia TSI the fuel lines are visible as they are centrally located but on the Superb (well 280 at least) they run under a panel nearer the drivers side sill.  Another Skoda dealer has told me there is a TPI and 'kit' for this fix which I believe are new clips but they wouldn't tell me the TPI number without having diagnose the issue themselves.  It's very annoying! 

 

I have another long term rattle behind the central dash vents too.  That happens above 3K revs, the door/B pillar vibration is at 1800-2200 revs. So I can chose do just just under 70 or just over and also never accelerate hard in the car.  Skoda is building in safety systems with poor quality control.  The dealer has one more chance to play ball or I'm getting a Hyundia i30N or Kia Stinger GTS.  I love this car but FFS I didn't shell out this much money to still have annoying trim rattles nearly 18 months after first reporting them.

This is on the Octavia, with the MQB cars I'd guess that the issue is shared across platforms: 

 

 

Will have a look at this later.

Thank you for the replies. 
 

As an engineering dunce, I’ll leave this to the dealer when it’s in I think. An annoying fault though.
