Good morning Adrian,
Much of this will be a repeat - so apologies in advance.
Again, if this were mine:-
I would not be worrying about it. It won’t have any beneficial affect on the car, but will have an adverse affect on you.
I would not be wasting money with Audi by ‘asking to put it on their diagnostic machine’.
’Just my luck to buy a car with a problem’. All cars come with problems (that’s why people sell them), so you could indeed swop this car, damage your wallet, and end up with some other unknown problem.
Oil burning will not result in the car going bang.
Monitoring the oil consumption would be good, so at least you know how much it uses in say 1K miles. I guess you don’t do a large annual mileage.
I would buy myself a 20ltr drum of oil to make its consumption affect as economical as possible., but before hand, I would experiment with 5w/40 Incase that reduces the consumption.
Finally, be wary of making any rash decision, and just give the issue some coats of thinking about over a month or so, otherwise you will probably end up making a decision you might later regret.
Just be positive and think it only boils down to the convenience of having to add some oil every now and then. Everything else can work out positive.
Definite repeat! - do not worry about it.
Just as an aside:- I clocked 80 last month, and that was great, and I can assure you I’ve ‘worried for Wales’ on occasions during my lifetime, but take a bit from my experience - it’s never changed anything, and the likelihood is something else will come along that needs worrying about!, and this problem will merge into the background.
As well as the inevitable car issues, I’ve got a bit of a recent major issue to now worry about, but when I see some poor folks at the treatment centre then I think -how lucky am I?
It’s a minor hiccup you have with the car Adrian, and it’s likely to give you continued good service.
Good luck with it and kind regards,
Gareth.
