Skip the dealer queue and the tow truck. Fixadblue’s mobile engineers come to you, anywhere across the UK, and permanently fix AdBlue and NOx sensor faults at the ECU level. No physical parts, no recurring bills, no repeat faults. Every repair is backed by a lifetime warranty, with same-day callout available.
Tell us about your vehicle — we’ll reply with a fixed price.
Most garages replace the part that failed. It fails again. We rewrite the ECU strategy that caused the fault in the first place — so there’s nothing left to break.
If the fault ever returns, we come back at no cost for as long as you own the vehicle. No small print, no mileage cap.
Book before midday and we'll often reach you the same day. No dealer appointment, no waiting a week for a slot.
We use the same genuine OEM diagnostic and ECU tools franchised dealers use — without the dealer markup.
Welcome to Fixadblue, the UK’s mobile specialists for AdBlue, EGR and DPF system failures. Most repairs don’t last because they only replace the failed part, not the ECU strategy causing it. We reprogram the system itself, so there’s nothing left to fail again, backed by a lifetime warranty on every job.
We’re backed by over 500 five-star reviews and customers who come back whenever a new vehicle develops a fault. Whether it’s a countdown warning, limp mode, or a no-start, our engineers come to you at home, work, or roadside. Get in touch and we’ll talk you through the fix.
We diagnose the real cause, not just the fault code. We reprogram the ECU to remove the failing strategy for good, and back every job with a lifetime warranty, most completed at your location the same day.
Car and van owners dealing with an AdBlue countdown, limp mode, or no-start. Fleet and commercial operators who can't afford downtime. Anyone already quoted a high price for a repair that's likely to fail again.
