Can you hear your turbo?
Posted: Mon Apr 16, 2018 12:12 pm
Since the weather has finally turned in the UK and we had one rare sunny weekend I broke the RS6 out of the garage for a Sunday blast.
Not sure I’ve ever driven it in anger with the windows down before but first thing I noticed was a strange rumble that seemed to rise and lower in volume precisely with turbo boost pressure.
I’ve had many a turbo car in the past and know that even with OE air boxes and recircs the turbo whistle is still audible albeit quiet.
Is this a normal noise or root for concern? It doesn’t sound like a whistle almost exactly like one of the aux belt pulley bearings is rumbling except it’s silent off boost and comes in with the turbos and also seems to be specific to the drivers side but could just be because I’m sat there?
My last MRC health check last month both front coolers were reported ‘slight leaks’ had one progressed to a more severe state perhaps? Turbo on its way out? Car boosts well and pulls very hard still, no loss in performance and no warnings on dash.
Advice, suggestions, comments? Thanks.
