20mph streets, Common roads and a sensible Mitcham remap
Driving in Mitcham has changed. Merton has been bringing in 20mph limits in phases, including around Longthornton and Pollards Hill, so a lot of local mileage is now slow and steady. That is worth saying at the start, because a remap does little for you at 20mph. Where it shows is on the open stretch of the A236 across Mitcham Common, or pulling a loaded van away from the Cricket Green with traffic behind you.
Vans are a big part of our Mitcham work, with the industrial estates around Streatham Road and Willow Lane close by. Commercial diesels often come with modest factory maps, and more low-down torque helps them carry weight without being thrashed in low gears. It also puts more load through a clutch that may already have covered a lot of heavy stop-start miles. We test for slip and read the injector and boost data before quoting, and if something is worn we tell you what needs doing first.
For family hatchbacks, estates and people carriers the question is usually whether a remap is worth it at all. For a small turbo petrol that does short trips, the honest answer is often no. For a diesel people carrier that goes fully loaded to the coast in summer, it can make the car far more relaxed to drive. The DPF, EGR and AdBlue systems stay working either way, so nothing about the car's emissions equipment or MOT status changes.
Carshalton Road takes you over the railway and tram lines at Mitcham Junction, past Beddington Corner and straight into London Road, Hackbridge. It's about 2.5 miles. Most jobs take two to four hours, and we open at 8am, so a morning drop-off usually means an afternoon collection. You'll get a written quote after the health check, and any repair we do before the remap is covered by our 3-month workmanship warranty.
