2017 S6 Avant vs 2018 Q7 costs and reliability

[SA1]

Evening all

I am thinking of replacing my 134k mile Discovery D4 with something newer.

Choice is between an approved S6 avant and an approved Q7. I do about 15k a year but split this with a 996, all are driven hard across rural countryside and city commutes. All go to the Alps in the winter a few times a year.

I am looking at running costs and reliability. What is the general consensus as they are both such good cars for very different reasons and so I think I am down to this question only.


Thanks!

I would check your like the autobox, there are issues of lag between pressing the accelerator and anything happening in the real world.

I have a 2021 S6, the diesel one and it is a pile of ste in this respect and many others.

Thanks. I should have said it’s a late model V8 but even on the test drive whilst it flew down the road, it took a while to respond to inputs. Though not as quick the Q7 was a bit better, late 18 plate with 270 odd ps. I guess it’s the more modern gearbox?

We also have a SQ5 bi turbo diesel and it’s the same, laggy when you put your foot down. My 996 tip is just instant go albeit not as fast.

It is an Audi trait that they are not interested in fixing so don't have any misconceptions Audi will be able to provide a fix for it.

If you do some googling you will see various gearbox maps that 'claim' to fix but these are for dsg boxes, if the box in the cars you are looking at is tiptronic there aren't many 3rd party options.

Make sure you keep up the warranty…. Google “Audi 48v starter generator problems”
