Worth getting a second opinion

A good friend of mine has his own car workshop and because he is getting close to retiement is not bothered about new customer,s he keeps busy with the customers he has. Last week he was asked to give a second opinion on a car owned by one of his customers brothers, basically he has been told that the car was not worth fixing as it needed a new engine and that was going to cost more that the car was worth. The car arrived and was obviously misfiring and running very badly, no codes and it had obviously had new spark plugs and coil packs. He did a compression test and everything was within spec.

He looked at the live data and it looked OK but he noticed that the Lambdas were both showing a lot of modifiers, within spec but he orderd a couple as thought it had to be worth a shot, as soon as he started the car it sounded better and the modifiers were within 2%. He took it for a test drive and it was obviously fixed. Total cost of 2 new sensors was under £150.

The car is a 9 year old Audi A3 with less than 70k on the clock, a new engine was going to be £6k.

The original diagnosis was done by an Audi dealer. You would think they would no better.
