Stage 1 remapping in Ealing
The M4 and the A40 both appear among Ealing's main roads, and Moto Heston Services on the M4 is just 5 km away. Yet the car on an Ealing driveway is far more often petrol than diesel: 65.8% of the 105,587 privately kept cars in the council area ran on petrol at the end of June 2026, against 15.1% on diesel. A Stage 1 remap is not only for diesels: on a petrol car, the same kind of engine settings are adjusted in software, within the engine's limits. On a diesel, the gain most drivers notice is mid-range torque, the pull you use when joining the M4 or overtaking.

In the 2021 Census, 24.5% of working residents in the Ealing council area drove to work, against 45.1% across England and Wales, and 36.8% of households had no car. Vans are relatively few in the council area: 4,219, or 40 for every 1,000 private cars, one of the lowest ratios of the 104 largest towns we cover. In 2025 MOT tests across W postcodes, the Mercedes-Benz E Class was the most tested diesel car and the Ford Transit the most tested diesel van. Ealing sits within the ULEZ like every London borough. Its daily charge can apply to cars and vans, and because a remap leaves the emissions standard alone, it makes no difference to whether you pay.
