THats my Original post....I have since replaced fuel cap sensor and put a recon rail on with sensor but still get ASR/ESP and anti pol faults on dash and a P2670 Actuator supply voltage b circiut low fault..what do you think...Cheers.
Puzzleingly the showed me the voltage readout of the sensor which was 4.7v this is only .3v short of what it should be at 5v.They then said that there diagnostics would not go as far as Peugeots so should take it to them for more info.
I took the car away and put my code reader back on and it gave me the codes P2670 and P2408,the Turbo boost fault had gone.I decided to tackle the fuel filler cap fault myself having looked into it on the net, once removing the old I found that had crack on the top, I ordered and replaced with new one ran my code reader the P2408 fault had gone, but the P2670 remained along with the Anti Pollution Fault and some seconds later an ESP/ASR dash readouts.
I asked about any Turbo boost faults to which they said the 2 codes they have given me where all that appeared.They informed me that the P2408 code involved a new sensor in the fuel cap in the region of £35 and the P2670code involved a Fuel Rail Sensor, because Peugeot only sell the whole rail with sensor and not just the sensor(although it can be bought seperatly of Ebay)this would be £160+vat and about £150 labour because of its position in the engine.
I then took it to the garage and suggested to them there may be a fault with the Turbo,they looked unconvinced and said they would put it on there Snap On diagnostics, some hours later they rang and informed me that there was nothing wrong with the turbo but had found 2 faults with codes P2670 Fuel Rail Pressure Sensor Suppl Voltage Too Low and P2408 Deisel Additive System Error Fuel Filter Cap Detection and also asked about the ESP fault on the dash but could not find a fault code for this.
Hi,Thanks for quick reply...this is my original post in 3 parts>>>> Appologise about the length of this...I have an 05 307 HDi 136 xsi with 135000 on the clock. Until 2 months ago it ran fine then the turbo blew.I replaced the turbo with a recon and once again it ran fine until last week when it threw up an anti pollution fault along with an ESP/ASR not functioning fault and went into limp 2500rpm mode.I bought an Autel MS310 code reader before taking it back to the garage who installed my replacement turbo, the 3 codes that came up where P2408 Fuel Cap Sensor/Switch Circuit..P2563 Turbo Boost Control Position Sensor A Circuit Range/Position and P2670 Actuator Supply B Circuit Low.
