AdBlue warning at London Gateway services

Where London Gateway services is

London Gateway is a Welcome Break site on the M1 between junctions 2 and 4, near Mill Hill in the London Borough of Barnet. It is the start of the M1, so it is the last stop heading into London and the first heading north.

London Gateway services is about 10 miles from central London, inside our London and South East 3-hour callout window. Where a van is free, we aim to be with you within 3 hours of you locking the slot.

If the warning comes on while you are driving

• Do not stop on the hard shoulder for an AdBlue warning

  A warning or countdown is not an emergency stop. Carry on calmly to the next services or a safe exit, unless the vehicle has lost power.

• Read the dash before you switch off

  Note the exact message and the miles left on any countdown. A photo is ideal. On some vehicles, switching off at zero means it will not restart.

• Lost power or in limp mode?

  Pull over somewhere safe, put your hazards on and get out on the verge side if you are on the motorway. Call National Highways or your breakdown cover first if you are in a live lane.

• Call or WhatsApp us from the car park

  Send the dash photo, your registration and which side of the services you are on. We tell you what it is likely to be and give you an honest arrival time.
