Accidentally put AdBlue in diesel tank
Accidentally put AdBlue in diesel tank — an accidental AdBlue fill is recoverable as long as the engine has not been started. Do not turn the key, do not move the vehicle on its own power, and call for a drain.
This is the most common call on this site and it very rarely ends badly, because most people notice at the pump. The bottle is designed to look like it belongs in the same place, the AdBlue filler is often beside the diesel filler under the same flap, and on a forecourt at night the two are easy to confuse. Noticing before you start the engine is the whole ball game.

Accidentally put AdBlue in diesel tank — what actually happens next
The sequence
- Do not turn the key. Do not press start. Ignition alone can prime the pump on many common-rail cars.
- Do not move the vehicle under its own power, and do not put it in gear.
- If you are on a forecourt, apply the handbrake and tell the station staff.
- Note roughly how much AdBlue went in and how much diesel was already in the tank.
- Call 01293 248666. Quantity and whether the engine ran are the two questions that set the job.
A technician drains the tank completely, catches the settled urea layer separately, flushes the tank and feed lines with clean diesel, replaces the fuel filter, refills with enough fuel to run, purges the lines and runs the engine under observation before signing off.
