These files have never been completely correct. Petrol stations on the wrong side of the road, others missing or in the wrong place. In my area a service station that closed at least 10 years ago is still shown. I suspect that if there is a version for the latest map it would still carry the same mistakes. I think these are more meant as window dressing rather than an accurate portrayal. The service stations details within the POI files are probably more correct than the 3dl file.
