A6 C7 whining gearbox

[will325]

I’ve got the same issue with my 2015 2.0 A6 ultra, it’s happening for me between 55 & 70 mph in 5th and 6th gear. It’s been into an independent garage and to the dealer and both have said it’s the characteristics of the gearbox/engine.
Ive been told they will ask Audi uk technical for feedback but I am not holding my breath.
With the car only having 16000 miles I was told at the start it needs run in or it might be because I am driving it differently from the first owner.
If I get any feedback I will be sure to share it

I have a 65 plate a6 avant ultra tdi stronic black edition I have noticed the whine from what sounds like maybe the gearbox diff on light throttle on the motorway 60mph plus. Is this a common issue?
Never notice sir before as radio was on but kids were unwell on a trip so radio was turned down and I noticed it now I can hear it all the time as tuned into it when on motorway.

Evening All.

I have a 2015 (15 Plate) A6 Avant, 2.0 TDI 190 Ultra C7 Auto (2WD) with just over 48,000 miles and have this exact issue also.
It's pretty much as you hit exactly 60mph on the speedo. That's when it's at its loudest, but it seems to get quieter over that speed.
I'm booking it in to the local VW Dealership over the coming weeks so will let you know how I get on.

I don't buy the 'characteristic of the car' thing for one second. I'm no expert, but i'm pretty sure a gearbox/diff shouldn't be whining to the extent you can hear it in the cabin.

Cheers.

I'm still no closer to getting this sorted. Any of you guys had any luck?

The local VW Dealer said they couldn't find a fault as they "couldn't drive the car over 50mph due to local speed limits" (I kid you not).
They're now saying it could cost £1000 to sort/diagnose if they can't claim under warranty.

I had a pre-facelift that has no issues whatsoever - wish i'd never swapped it now!!

Tell them to take it elsewhere then

I've been looking at buy a 2016 A6 Avant 190 for a last few months, spending some time looking at potential problems and keeping an eye out for good deals.

This gearbox whine is pretty ridiculous for a luxury car, I started to think the diff is just not set up correctly, like the backlash tolerance is wrong, but highly unlikley from factory on multiple cars.

This does remind me of my Subaru Impreza though, almost all models WRX & STI, certainly up to 2007 (probably after as well) they all have a harmonic diff whine at 62mph... all of them, it's just how it's worked out, nothing wrong with it, just a little annoying. wonder if that's what is happening here...?

Just my 2 cents.

I'd still be wanting an answer.

Hi Guys I’ve had the car into another specialist and they say characteristics of it. But I’m convinced the pinion bearing is failing. Today once warm on the motor way . My 14 year old daughter says to me what’s that noise on accelerating she can even hear it with radio on. I’m a technician myself and think it’s the pinion. But no one else seems to be able to hear it.
Have you guys had anymore luck on this issue.

Part of the problem may be that once you're aware of a noise, any noise, that all you can hear. For me it's the neighbors bloody washing machine. Wife can't even hear it. #drivingmemad

Hello everyone,
I own Audi A6 (C7) 2.0 TDI Ultra S-Tronic from 2016. I hear whistling/whirling sound when accelerating slowly or harder from 60 mph/70 mph at 4th, 5th, 6th or 7th gear even if I drive slower and want to accelerate this sound is hearable from front of the car. The sound comes from left/centre/front side of the car and is noticeable behind the dashboard. When I switch gear on neutral when driving is quiet also if car is stationary on parking gear to do revving nothing is happening as well. The sounds appearing only when accelerating not when revving. I have 2 videos as a proof. Thank you

Having had major issues with my A4 (Multitronic) and being in Cambridge - if you are using Vindis (Cambridge or Huntingdon Audi) I've not had good experiences (even with my current A6!) - though I only had excellent support from Bury St Edmunds Audi (Marriott Motor Group) who were very supportive with the A4, and when it nearly got me broadsided by an HGV they took the car off me and replaced the whole gearbox and dealt with Audi CS whom had said that all the behaviours were normal - whereas all the other dealers have insisted (which I didn't pay for in the end) that I start by paying for a gearbox oil change to "fix the problem".

That said, if you want an independent, Chris @ VW Technics in the village of Willingham has got most of a lifetime on VAG cars and knows his onions......VW Technics | VW,AUDI,SKODA & SEAT CAR SERVICING AND REPAIRS BASED NEAR CAMBRIDGE. - he looks after my and several other A6 Ultra's from friends near/around me and if nothing else might be worth a call to ask?

HTH,
