Hello Karl, Really sorry to hear of your plight, but am I too surprised? Regrettably, no. You said Audi claim it has full service history, and their claim cannot be refuted, but extending oil and filter changes to every 18k miles is asking for trouble. My stab at why, leads me to believe that cars are sold new, and Audi - like many other marques - want to keep the servicing cost down during warranty, to make the sale of service plans seem value of month to rental companies and private individuals alike. After the warranty has expired, and leased cars are returned, they are sold with FSH, and manufacturers couldn’t give a toss about how long they last under this service schedule - as you have found to your cost. They now want you to part with tens of thousands of pounds to start again! How many services have you had done during your ownership Karl. Re. another engine, paying out £20k would be bonkers on this 10 year old car, and respecting Cliff’s views on secondhand ones, this would still be my chosen route - if you are not prepared to scrap it. Car are frequently deemed to be beyond economical repair - body damage wise, and engines from these may well be worth investigating. Regards, Gareth.
