Another warning has been issued to operators not to fit emissions-cheating devices to their vehicles.

In a statement, the Office of the Traffic Commissioner recognised that some operators claim to have bought vehicles without realising AdBlue emulators have already been fitted, while others have fitted them intentionally.

It said: “Operators experience problems with the AdBlue system and look for a way to fix them.

“Instead of going to an authorised dealer or taking professional advice, e.g. from the Driver and Vehicle Standards Agency or a solicitor, they speak to someone who says that installing an emulation device will bypass the AdBlue system and resolve the performance issues.

“This is bad advice. It should never, ever be followed.”
