AdBlue and SCR Diagnostics
SCR faults can leave modern diesel vehicles counting down to a no-start condition. We diagnose the system and explain the practical repair options before money is spent on parts.
Common AdBlue Faults

Practical Advice
Some SCR issues are simple. Others can be expensive if parts are guessed. We identify the fault path clearly and help you decide the most sensible next step.
Off-road and competition use only. Options such as DPF, EGR, AdBlue/SCR, GPF and catalytic converter removal, fault code (DTC) disabling, speed limiter removal and pops & bangs are for off-road, motorsport or competition use only. They are not legal on public roads in the UK. Removing a DPF is an MOT failure, with fines of up to £1,000 for a car and £2,500 for a van (GOV.UK). You are responsible for the legal use of your vehicle.
