Who We Are
15 years in the trade, now fully mobile
Mobile AdBlue Fix is a mobile diesel emissions service with 15 years in the trade behind it. We work on AdBlue, SCR and NOx faults on cars, vans and fleet vehicles, and we do the work where the vehicle is parked: at home, at work or in the yard.
We are based in Copthorne, near Crawley and Gatwick, and cover London, Surrey, Sussex and Kent. You can see every town we cover on our areas covered page.

What We Do
Diagnosis first, then the software fix
Every job starts with a proper diagnosis. Our diagnostic visit is £185, and that £185 is included in the price if the full fix goes ahead on the day. We read the fault codes and live data, find out what has actually failed, and tell you the price before any work starts.
The full fix starts from £249, and most jobs are £249 to £450. Bespoke or very distant jobs are quoted separately, and so is ECU unlocking if your vehicle needs it. See our prices page for the full breakdown.
- Diagnostics: fault codes, live data and a clear answer on what has failed
- AdBlue and SCR fault repair in the ECU software
- AdBlue delete or bypass for eligible off-road, export or motorsport vehicles only
A delete is not lawful on vehicles used on public roads, so we check eligibility before any delete work. The software fix is permanent unless you ask us to reverse it.
What We Do Not Do
No NOx sensor replacement or cleaning
We diagnose, bypass or delete in the software. We do not clean, fit or replace NOx sensors, and we do not supply or fit other SCR parts. If your vehicle needs a new part, we will tell you so after the diagnosis.
Our Promise
Lifetime warranty, no deposit
If the work we carry out ever gives trouble, we put it right at no charge. That is our lifetime warranty.
There is no deposit to pay when you book. You pay after the job, once the work is done. We also work on a no fix, no fee basis: if we cannot resolve the fault, you are not charged for the repair.
