Disabling AdBlue (AdBlue OFF): A quick fix with heavy consequences

Faced with outrageous £1,200 quotes to replace an SCR tank, many drivers turn to an unofficial solution: 'AdBlue OFF' reprogramming, charged around £250 by independent tuners.

Why it's Illegal

Electronically disabling the anti-pollution system is a direct violation of road traffic and environmental laws. If caught, fines can be severe. Furthermore, modern MOT testing equipment is increasingly capable of detecting this software fraud, resulting in an immediate failure.

Voiding Your Insurance

In the event of a serious accident, if your insurance assessor detects that the engine ECU has been tampered with (which is systematically logged), your insurance may declare your policy void. Do not take this risk. Fight legally with our collective to obtain a proper repair.
