AdBlue warning at Heston services

Where Heston services is

Heston is a Moto site between junctions 2 and 3 of the M4, in the London Borough of Hounslow. It has a site on each side of the motorway, so tell us whether you were heading into London or out towards Heathrow and Reading.

Heston services is about 11 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.
