After a spell in the wilderness I’m back with an S4… however this one has an annoying buzzing noise about it which I will try and describe.
- It’s a hum/ buzz noise. A little bit like when you put your mobile phone close to a speaker and you can hear it do it’s periodic handshake with the network.
- Not impacted by engine speed, doesn’t alter with revs
- Not impacted by road type, the smoother the road the louder it seems
- Radio and hvac off - noise still there
- Can’t be heard at 30 mph, but can be heard at 50 and above
- it’s not ‘that’ loud, as speed increases above 50 it gets a little louder but not much. Radio will mostly drown it out
- Seems to me to be coming from around the dash cluster, if I stick my head forward of the steering wheel the noise seems louder
- I’ve pressed down on all speaker grills, trims etc to see if that helps narrow it down but nothing changes
- I’m pretty sure it’s resonance rather than electrical or mechanical. Maybe even aero related but I can’t find / see any loose covers or trim outside that would cause it.
