Fault guides

DPF, EGR & AdBlue fault guides

Straight answers from a working Salford workshop. If your van or car is showing a warning, start here — then send us the reg for a fixed price.

What happens if you don't use AdBlue?

The warning sequence, the mileage countdown and the point your engine refuses to start.

700, 500, 200 miles — what each stage means and how we clear it in Salford.

Limp mode, smoke, poor MPG and the warning lights that point at the filter.

Regeneration, on-car cleaning and off-car cleaning — what actually works.

Tank, pump, injector, NOx sensors — how it works and where it goes wrong.

What the light means and what to do before it turns into a bigger bill.

Local pages with the questions drivers in each town ask us most.

Salford workshop, M7 1UL. Fixed prices from £180, most vehicles same day.
