"Night and day difference. Van feels like it's had a new engine."
"Warning light's gone and it pulls properly again – saved me a fortune."
"MPG is up and it's quieter on the motorway. Worth every penny."
"Booked in quickly, really professional – highly recommend."
"Had been getting warnings for months. Thought I'd need a new DPF but they sorted it. No warnings since and it's running better than ever."
