Hi, had a 3rd AVS service at 50k on my 54' A4 TDi Multi Sport at Audi Cov last week. The service reminder has now just populated from blank ---- to show 522 days or 8700 miles. I thought service intervals were between 10 - 12k? Can anyone shed any light as to why its so short? I do a good mix of town and motorway driving probabaly covering about 14k a year.
