Wheel bearing?
Intermittent rumble at highway speed
Update: checked for codes… none. It’s running clean. However, I did find a front tire running low that may have been a factor in this, with one wheel revolution out of synch with the others. Monitoring…..
Hi, new guy here. I did some searching but did not see anything like this issue I've had maybe 4 times in as many months. 2015 Q5 TDI with 112k km, fully serviced, no other issues. A few minutes after getting on the highway a low rumble type noise started getting progressively louder. Could not discern where it's coming from, but it was getting louder and louder even as I slowed to a stop. Nothing obvious as I did a once around the vehicle. Got back in, and it was gone. The next 3 times it occurred, same thing.... it began at 115-120kph after being on the road for 5-10 minutes, got louder and louder even as I got off the highway, and then after the vehicle was stopped and then started moving again, its gone, for another month. I haven't checked for codes. My gut tells me maybe it's got something to do with at AWD getting out of synch or a sensor giving false info, but that's just a guess. Has anyone encountered anything like this before?

Welcome. I have not heard of that problem before. Are all tyres inflated to the correct pressure? When you stop try to check the wheel temperatures, if one is hotter it could be a bearing or brake problem (dragging caliper). Failing that check for fault codes.
Thx. I will toss a digital thermometer in the car to check trmps next time it occurs, but having dealt with dragging calipers and bad bearings on other vehicles over the years I don't think this is it. The symptom literally disappears as soon as the car is stopped and then begins moving again, and it sounds like you are driving right beside a rumbling train - low frequency rumble throughout the vehicle. I've tried recording it but probably need to hear it on a home stereo because a phone can't reproduce sound that low properly.Welcome. I have not heard of that problem before.

Don't think so.... it completely disappears as soon as you stop and then start driving again, and may not return for a month. Also, it's not affected by steering left or right while the noise is occurring.Welcome to our forum

Mine did the same 2022 s line..engine felt like it was lugging ....at 17000km the engine went boom....rod bearing recall...now waiting for parts...😎
This is a TDI diesel, not gas. And the sound isn't from the engine, it seems to be underneath, but disappears after stopping, and may not re-occur for over a month.....
