Audi C7.5 S6 Avant - purchase advise-engine/turbo concerns

[BenB91]

Hi all

I'm looking at a 2017 S6 Avant with circa 70k miles. Full audi service history.

I'm not too informed on this, but I believe there are reliability issues regarding the engines/turbos?

Should I be concerned by this? How common is it? Possible repair costs?

An extended warranty is circa £125 p/m with Warranty Wise.

Thanks

There was a known issue with the oil filters on the turbos getting clogged, which could result in a costly turbo failure. For a while I combatted this by changing oil every 9 or 10 months (my S6 was a daily). But a year or so ago Audi recognised the problem and did a recall on all v8 twin turbo engines from this period. So I would ask the seller if they have records of the car being sorted by Audi.
Otherwise the engine / turbo set up is nigh-on bulletproof as far as I'm aware.

Thank you. Seller has confirmed recall work has been carried out by Audi.
