Stage 1 remapping in Chorley
Over the year to June 2026, the number of privately kept diesel cars in the Chorley council area went from 20,508 to 19,015, a fall of 7.3%. Across England the drop was 5.3%, so diesel is thinning out faster here than in the country as a whole. Even so, 31.1% of private cars in the council area still ran on diesel at the end of June. For an owner keeping one, Stage 1 remapping changes the fuel, boost and timing settings through software, inside the engine's limits, and the result is stronger mid-range pull. A car with a fault, such as a blocked DPF, a failing EGR valve or a sticking injector, is repaired before any remap.
