How long does an opened container last
How long does an opened container last — less than a sealed one, and less again if stored warm. Check the container — manufacturers state shelf life against a storage temperature band.

How long does an opened container last — the context
AdBlue has a finite shelf life because urea hydrolyses slowly to ammonia, faster when stored warm. Keep it sealed, out of sunlight and cool, and use a clean funnel — contamination and age are the two ways good fluid goes bad.
Why it degrades. Urea in water is not indefinitely stable. It converts slowly to ammonia and carbon dioxide, and the rate rises sharply with storage temperature. This is why shelf life is quoted against a temperature band rather than as a flat date.
Storage temperature. Cool and out of direct sunlight. Freezing is not the problem — the fluid freezes at about −11 °C and thaws back to specification unharmed. Sustained heat is the problem.
It is worth separating SCR from the DPF before acting on any advice. Both sit in the exhaust, both light a warning lamp, and the standard advice for one — a long run at motorway speed — does nothing at all for the other.
The call-out is £89 to £199. An AdBlue tank drain and flush is quoted on the phone before a technician travels. If the SCR system needs component replacement — dosing injector, pump, tank or catalyst — that is separate, and you will be told before any work starts. If this is a job we cannot fix at the roadside, we will tell you that on the phone rather than after we arrive.

What customers say
4.8 out of 5 from 2,190 Trustpilot reviews. What reviewers mention most is that the technician stayed calm and professional with a driver who was embarrassed and stressed, and that somebody arrived when they said they would.
The most common criticism is price. People do not expect a wrong-fluid job to cost what it costs, and that is a fair complaint to publish rather than bury. The answer is the Call-out from £89, a quote given on the phone before a technician travels, and being told when a job cannot be done at the roadside rather than after somebody has arrived and charged for the visit.
