Thanks, My mechanic didn’t sound like he wanted to do it and was adamant it wasn’t necessary Total miles is 146,000 and it was last changed in 2022 on 96000 (just before I bought it, the garage supplied the paperwork). As with all cars, I intend to keep this one until it’s uneconomical to maintain. I had my last Audi a6 until it was 17 years old with 196000 on the clock.
