Hi All,
First post so bear with me.
Recently became the owner of a Oct '05 307 XSE HDI 2.0lt 16v. Unfortunately I didn't check the FAP additive level prior to purchasing as the car (had a full Peugeot service history including pre-purchase service) and wasn't aware of the FAP dosing system at the time. Regardless, the reservoir seemingly emptied a few months after I purchased it as I received an 'unpollution system faulty' warning on the dash, and upon inspection found empty.
I purchased and refilled the eolys reservoir and had the local mechanic clear the fault and run a forced regeneration. Having done approximately 1,000kms it got a full service - noted the issues to the Peugeot dealer and no concerns raised in service follow up.
3,000kms (mainly highway) since, the car felt as though there was pressure on the exhaust system as whenever the turbo was about to start spooling up there seemed to be a lack of performance and tentativeness. Soon thereafter (the same short trip around town) I stopped at the car, and when I returned to start it back up I received a 'speed management system faulty' and 'unpollution system faulty' warning. Also the cars performance was seemingly significantly reduced - limped to the mechanic.
Local mechanic (non-dealer as they are 2 hours away) plugged in and found the following fault code - 1429 Differential Pressure Signal Coherence on Startup. He was also unable to make the car perform a forced regeneration.
Since then I've purchased a new FAP differential pressure sensor (sounds like they regularly have issues with water ingress?) which I expect to receive shortly and intend on replacing next weekend - part number 1618Z9.
Has anyone had experience in replacing these and any valuable tips? Also is there any reason not to think this is likely the culprit given the faults and issues? i.e. sensor not functioning correctly, and thus not calling for regenerations to occur = build up in FAP and reduced performance?
Any assistance would be great.
Cheers,
