Peugeot 407 2.0 HDi 2005 - Code P1445 fuel additive overfilled - Fixed #

Year of Manufacture *: 2005
Engine Size and Code *: 20hdi rhr

Hi all
Had the above vehicle in on saturday with engine management light on, fault coded and came up with p1445 fuel additive overfilled. Looked in fuel additive control module and no fault codes stored, looked in live data and it says that fuel additive has not reached minimum level. I've searched in the archieves and can only find the same problem on a 307, one of the posts mentions about renewing the additive cotrol module. Will the additive system be the same as the 307 and also has anybody had same fault on a 407.TIA

Regards Jamie

Hi all
Had another look at this the other week, checked the additive level in the tank and its just under full. I tried disconnecting and reconnecting the additive ecu with the ignition on but no good. I then tried disconnecting it and then clearing the fault in the engine ecu. The fault code didnt come back untill i reconnected the additive ecu, so i thought it must be in the ecu. Renewed the ecu and reconfigured but no good fault code comes back with ignition on after about 10 secs. Has anybody got any thoughts on this or give me some advice.

Regards Jamie

Hi Steve
Thanks for your reply, when i replaced the new additive ecu i set both the counters to the original readings, then put the engine code in and the transmission type. I have found out since that this code doesnt mean that the additive is overfilled. It means that the ecu has injected enough additive for thelife span of the DPF, so i reset the first counter which cleared the fault code and told my customer that the may want changing.

Regards Jamie
