Yes, that rumble is similar to the noise I had in a Tiguan TDI, the garage diagnosed the DMF and said it should be changed before the clutch housing gets damaged. Not a cheap option. Hope you get this fixed. HNY!
In my particular case, it sounded more like an actuator from an electronic handbrake moving on or off. If I’m hearing your one correctly that sounds like a rumble or train track noise. I’m assuming it’s a TDI.
I have just had the above warning appear on my A5 MY17 2.0 TFSI, with advice that you can continue to drive the car. Luckily, I came across this lengthy thread on another A4 forum which I feel is worth linking, as the fix is simple and the consequences of continuing to drive could be expensive...
I have a March 2017 registered car and they were talking about it on the forums then, so Audi dealerships must have known?
I guess that’s it, after 15 minutes the map on my MY17 A5 reverts to this screen and doesn’t seem to recover to even the basic map overlay. I assume I’ve lost the Google Earth overlay, which I understood was meant to stop on 1 January 2021? Funny how it wasn’t mentioned when I bought it?
I had a similar problem, having had an oil and inspection service done recently but still showing the inspection due in March next year. The stealer's explanation was that it needed the brake fluid changed then so can't extend the inspection beyond March. Crazy.
Slight thread drift, but my wife’s MY17 Golf shows the radio text ie who’s currently playing, whereas my MY17 A5 doesn’t - you have to go to a separate page despite the MMI screen having lots of blank space to display it.
