Hi, just had my Audi Q7 2020 TFSI serviced & on inspection of the oil filter there was quite a lot of metal Glitter fragments contained in it. I’ve been advised that this requires the engine to come out to see exactly what the problem is as there’s a number of areas of the engine that this has come from. Is this usual for the Q7? I’ve done 96,000 miles. Thanks for any help you can give.
