Hi
Maybe my mistake was to buy the new S5 Avant model (one of the first in the UK) before they finished developing it....
I had previously an S4 Avant, which I bought new (because I wanted the Adaptive cruise after experiencing that on my previous Jaguar Super V8) and kept for 10 years and 10,000 miles. in the first years (before I retired) I did 20,000 per year, but less than 10,000 latterly. It was reliable and did everything I needed, including towing classic/vintage cars on trailer. Best towcar I have had and a good towing capacity (2100kg). I would have bought a new S4 but was avoiding the diesel version, so when the petrol S5 replacement was announced that seemed the ideal replacement. I would never have an SUV ...
So my S5 is the Launch Edition, intended for dealer showroom/demonstrator 4 months ahead of general availability in November 2024. Stratstone offered me one as they had one more ordered than Audi required them to have. It has all the extras, except the pan roof for some reason and Stratstone did me a good deal on the price.
It didn't have a towbar, but I thought I could add that, as I did to the S4. However I found that you cannot add an aftermarket towbar as with the new coding protocol it is impossible to code anything other than an original Audi one - which costs over £2,000, or would if you could get one (though they are fitting them on the production line to order). After a year of asking Audi said it is available, but "on back order", I ordered one 2 months ago and still no date.
Everything is on back order ... it took 2 months to get rubber floor mats, 3 months to get a windscreen after mine cracked - and now my interior mirror has detached from the screen (hanging by wires till I stuck it back with double sided tape) - the dealer said the windscreen needs replacing again as the bonding has separated - no news on when that will appear!
I have had 3 software updates so far (one of which followed a stranding with a dead/unresponsive car), but still have some gremlins. Today, for example, the cruise control would not work because it said a door was open - though I have checked all the doors and re-opened and closed them.
So already this has been the most unreliable car I have owned in over 50 years (revealing my age there!) - a contrast to the last Audi, and the dealer service has been poor (they have one technician that is very good and customer friendly, but the 'front of house' people who you usually have to contact are hopeless, they don't have any technical understanding and don't return calls etc.). After the first 3 years I used a good local Audi specialist for the S4, at less than half the cost.
Rant over ... it is good to drive, performs well, is (only slightly) more economical than my S4. The adaptive cruise is better (old one didn't work below 5 mph). Some of the tech is good, when it works, though some is too nanny-ish.
You guys are coming down from larger cars, for me this is significantly larger and heavier than the S4, with less room inside, especially storage. So not so easy to park in congested Cambridge! (I had downsized from an excellent but LWB Jaguar). Nowhere to put the tyre pump (I had a spare wheel in the S4!) or first aid kit (was in the rear arm rest of the S4).
I don't think I will buy another Audi it would seem they have gone downhill. Product development, incomplete; parts supply, inefficient and poor customer service (not just the dealer, Audi UK are no better).
I hope your experience is better than mine!
