Nobody enjoys a surprise repair bill. This guide sets out realistic UK costs for fixing an AdBlue fault the conventional way versus a permanent ECU-level removal, so you can make an informed decision.
Typical dealer and garage repair costs
Diagnostic check: £60–£150 before any parts are fitted.
NOx sensor (genuine): £250–£500 per sensor, and many vehicles carry two.
AdBlue pump / delivery module: £400–£900 fitted.
AdBlue injector: £200–£450 fitted, more if urea crystallisation has damaged the housing.
SCR catalyst replacement: £1,200–£2,500 on some vans — the worst-case outcome.
What permanent removal costs
AdBlue removal is a one-time, fixed-price job carried out through the OBD port. There are no parts to buy and no labour for stripping exhaust components.
Because we work mobile, you don't lose a day to a garage visit or pay for a courtesy car — we come to your home or workplace and most jobs take 60–90 minutes.
0% payment plans are available if you'd rather spread the cost, and we operate a no fix – no fee policy.
Working out the true cost
The important number isn't the first repair — it's the total over the next five years. NOx sensors on short-journey vehicles regularly fail again within 12–24 months.
Two sensor replacements plus diagnostics over three years can comfortably exceed £1,000. A single permanent removal ends the cycle and carries a lifetime warranty.
For fleets, downtime often costs more than the repair itself. A mobile fix that keeps the van on the road is usually the deciding factor.
Frequently asked questions
How much does AdBlue removal cost in the UK?＋
It's a fixed one-time price that varies by vehicle and ECU type — call or WhatsApp us with your registration for an exact figure. It's typically a fraction of the cost of repeated NOx sensor and pump replacements, and 0% payment plans are available.
Is AdBlue removal cheaper than replacing a NOx sensor?＋
In most cases yes, especially when a vehicle needs two sensors or has already had one replaced. Removal is one payment with a lifetime warranty rather than a repair that may need repeating.
Do you charge if the fix doesn't work?＋
No — we operate a no fix – no fee policy.
