P2269: Water in fuel detected
The filter sensor has detected water built up in the diesel. The filter needs draining soon so the water does not reach the injectors.
| Code | P2269 |
|---|---|
| System | Engine and transmission |
| Group | P22xx, NOx sensors, oxygen sensors and emissions |
| Type | Generic: it means the same on every make |
| Can you keep driving? | Better not |
What P2269 means
The diesel filter holds back water carried in the fuel and a sensor warns when too much has collected. If it is not drained, water can get into the high pressure pump and injectors, which are very sensitive and expensive to repair. It usually comes from contaminated fuel or condensation in the tank.
Most common causes
- Water collected in the filter that needs draining
- Filling up with diesel contaminated with water
- Condensation in the tank from often running with little fuel
- Old or saturated fuel filter
- Water sensor giving a false alarm (if the warning stays after draining)
Symptoms
- Engine warning or water in fuel light on
- Jerking or uneven running
- Hard starting
- Loss of power
Can you drive with P2269?
Better not Only drive as much as you have to until the filter is drained: water can damage the high pressure pump and injectors.

How to check it
Diesel filters usually have a drain screw or tap underneath: letting a little out into a clear container shows whether there is water (it settles at the bottom). If a lot comes out or the warning returns quickly, have the tank checked.
How to read and clear P2269 with Final OBD
Plug an OBD2 scanner in under the steering wheel, switch the ignition on and open Final OBD. Under Faults you’ll see P2269 with its description and whether it’s confirmed, pending or permanent.
If the engine stores it over standard OBD, with FREE you read this code with its explanation for nothing and clear it. With PRO you also read the faults of every control unit and clear them in all of them.
Clearing the code only turns the light off: if the cause is still there, it comes back. Clear it once it’s fixed, and not right before an inspection. It’s all in how to read and clear fault codes and in inspections and OBD.

How do you clear P2269?
With an OBD2 scanner and an app like Final OBD, which clears it for free if it’s stored by the engine control unit. But clearing it only turns the light off: if the cause isn’t fixed, P2269 comes back.
Read it on your car
Final OBD reads and clears engine faults through standard OBD for free, each one explained in plain English. With PRO it also reads the faults of every control unit, each make’s own codes included, and clears them in all of them.
