A commercial town beside Slough
Langley is a commercial town on the Berkshire side of the M4, joined to Slough but with its own station, business parks and trading areas. Vans leave the yards here for the motorway, the rest of Slough and the Thames Valley. Plenty of their work is short and repeated: a loading bay, a drop in Slough, back to the yard. Short runs and idling at the M4 junction 5 roundabout stop the exhaust reaching the heat that SCR needs. Over time urea builds up, and the sensors and the heater report problems.
Langley is about 19 miles from central London, out along the M4. That puts it inside our London and South East 3-hour callout window: where a van is free, we aim to be with you within 3 hours of you locking the slot.
Motorway and trunk roads around Langley
M4 junctions 5 and 7
Junction 5 sits close to Langley and junction 7 is the other way into Slough. Drivers who see the warning here should leave the motorway first, and we meet them on an ordinary road.
A4 through Brands Hill
The Bath Road passes Brands Hill, a short drive from Langley. It stays busy with vans doing short, slow hops between stops, which is hard on a cold SCR system.
Langley Park and Waterside
Business parks around Langley Park and Waterside feed vans onto the M4 and the A4 all day. Standing, idling and slow shift-change queues keep exhaust temperatures low.
Stations, business parks and Waterside
Areas and estates (SL3)
We work in yards and on drives around Langley station, the business parks near it and the Langley Park and Waterside area. We also reach Brands Hill, Middle Green, Datchet and Slough from this page. Give us a road name and a nearby landmark, and we agree whether the work is best done in the yard, at the loading bay or on a quiet street where stopping is legal.
Vans and cars we see here
Transit and Transit Custom vans from the trading yards, Sprinters and Crafters on parcel work, Boxer, Relay and Ducato panel vans, plus diesel Audi A6, Volvo XC60 and Range Rover cars used for work in Slough.
Faults that hit Langley vans
No-start lockout
Vans that sit in yards at the weekend can wake up on Monday with the countdown at zero and no start. If the countdown is running, ring us before it reaches that point.
P20EE
P20EE points to poor SCR efficiency. Short M4 hops from the yard to Slough and back are a typical cause, because the catalyst never stays hot long enough to work properly.
Quality sensor fault
Contaminated or old AdBlue triggers a quality sensor warning. Vans stood in a yard through summer sun or winter frost are a common cause on commercial sites around Langley.
Yard and loading bay repairs
Many Langley firms keep vans in the yard between shifts and send them out early on the M4. We can come to the yard or loading bay during our hours, 6am to 9pm, seven days a week, so the van does not need to move. For small fleets, tell us how many vans show a warning and where each is parked. Single drivers can book a driveway visit in the same way, with no workshop trip across Slough.
Working at Langley sites
We can work in private yards, at loading bays, on drives and in public car parks where parking is allowed. We cannot work on the M4, on its slip roads or on a busy stretch of the A4. If you are near Heathrow, we stay landside only, on public roads and private sites, never airside.
A legal repair in Langley, not a workaround
Langley vans drive in and out of the Ultra Low Emission Zone around London, so the fix has to leave the AdBlue system working as the maker intended.
We fix or replace the part that has failed: the NOx sensor, pump, heater, injector, tank, quality sensor or wiring. We never switch off or strip out AdBlue or SCR. Doing that on a road vehicle is not road legal in the UK, it can fail the MOT and it can affect your insurance.

Work starts from £249, and that price is fixed before any travel or work. We read the fault codes and live data on site in SL3, tell you which part has failed and agree the total with you first. No fix, no fee on the agreed outcome.
