Megane 2 1.5 dci 2004 water in diesel detector

**Andr33iy98** · 24th January, 2022, 02:56 PM

HI,
I have a megane 2 without water in diesel detector fitted, but I have this dtcs.
Can someone erase it from ecu dump ?
I can save dump via renolink china obd clone and also rewrite with dtcs off ? DF057 is my problem.
Also on dash appears check fuel filter, but filter is replaced already.

Also, I reset crash data from airbag, but some dtcs still persist.

Hi. This probably has nothing to do with resetting an airbag crash. At the bottom of the fuel filter you have a water sensor. Unscrew it and drain the contents of the fuel filter. Screw the sensor back in (preferably replace the fuel filter right away) They should clear the DTCs normally. Best regards

Mine does not have fuel sensor, Also no water because is new, car works fine.
I just want to delete this in flash from ECM

canclip should help, possible short circuit on the plug prepared for the water sensor

see if you have the wires led out?

Does not seem to be the same. This is the only plug which is not plugged in something.

Engine type: K9K722

Most PSA has a 3-pin sensor, as the resistor would have to give it to lower the signal (1Koh). Peugeot has 9v on the signal with the plug unplugged. The other two are ground and 12V power supply.

but 1.5 dci is not from PSA I think, what this plug would be?

just check pin2 if it is in the connector of the b3 controller, look for such a sensor .you don't have to screw it in

I understand. It didn't activate itself after all. Try to connect a different tester. Not that this one misleads you and gives you other errors. See what tension you have on this ankle as shown in the photo. Or see if there is a free cube somewhere near the fuel filter. Can be excluded from the file. Where is the file? It won't read itself.
