Peugeot 206 2002 - DPF resevior level

[Andywill]

Got a 406 2002 2.0HDI with a perminant DTC in the DFP ECU - FLUID LEVEL SIGNAL PERMINANT FAILURE. The resevour was empty, and have now filled it. The resevour has four cables - 2 for the pump and 2 for the level sender. Does anyone know if the level sender inside the resevour is a variable pot, or just a simple float and contact that makes when the fluid is empty/full. Thanks all.

As i know that tank does not as a traditional gauge as on fuel tank, so once you have topped up the tank you have a speciall procedure on planet 2000 that you should carry on in order to reset the level quantity.

III - LOW ADDITIVE LEVEL SENSOR (1283)

A - Role

The sensor informs the additive ECU that the low additive level has been reached when there is 0.3 litres remaining in the additive tank.
Depending on the information received, the additive ECU informs the fuel injection ECU.
The injection ECU informs the BSI which requests activation of the following:
? request to flash the service LED on the control panel (*),
? request to display a message on the multifunction screen (*).
Note: 0.3 litres of additive is sufficient to fill up the tank 6 times with 80 litres of fuel (*).
(*) depending on vehicle equipment.
B - Description

The sensor consists of a thermistor.
The information provided varies, depending on whether the thermistor is in the additive or in air (minimum level reached).
C - Location

The sensor is incorporated into the additive injection pump.

Thanks guys, great. So its a thermistor? Have carried out all the usual resets using planet, but the code for the FLUID LEVEL CIRCUIT remains. Am happy the cabling/connections are good, and measured approx. 8V down the signal line to the sender. Perhaps a dud DPF ECU. I've heard of Peugeot changing these controllers for different issues.
