Diagnoza Auto Simon in Timișoara cleans particulate filters (DPF), EGR valves, turbos and injectors without dismantling them. On Google it has 4.5 stars from 174 reviews. That is exactly the kind of proof most businesses wish they had.
When I looked at the profile on 7 October 2026, the reviews were not the problem. The “Website” button led to an old domain that had ended up with a betting site, the category said “smog inspection station”, and the map pin sat near Battonya, in Hungary, with no address. A driver who trusted the stars and tapped the button landed somewhere else entirely.
Good reviews alone are not enough when the profile data is wrong. The new website, curatarefiltruparticule.ro, went live on 12 October 2026. The profile corrections are prepared and go in one per day once the owner gives manager access, which hasn't happened yet. The whole story is in the case study.
