Hi guys,
Wondering if anyone has some input to this problem, ill try keep it short;
I am a Peugeot mechanic, not a tuner but I am familiar enough from playing with EDC15 a few years ago etc.
A customer brought me a car (1.6 110 hdi 307)that I diagnosed as having a bad egr, they declined repair and went and got the DPF and EGR written out by 'some guy'. The car never started again after he went near it. It was towed back to me and I opened the original ecu to see components broken off board, eeprom ruined etc......great!
I ordered a plug and play ecu with DPF and EGR removed and Immob off from a well enough known and respect tuner! This got the car to fire right up and it runs and drives fine with no EML, however I still have 3 codes persisting:
P2121 & P1152 - for air heater throttle position copy signal.
P1434 - Open circuit additive pump motor.
Car is fitted with air doser with 2 flaps, one for intercooler bypass and the other for throttle restriction. I tested it on another car and it works but doesn't move with this ecu and fails to activate with component test. Live data says requested signal is out of range (should be in the 0-100% range). Wiring is fine.
Car is also fitted with just an additive pump, no additive ecu. The pump can be accessed with diagbox and commanded on and works fine but not through the engine ECU.
Tuner has been very helpful and I have no reason to doubt him. He says its a compatibility or config issue and not a mapping issue but I have tried every diagbox config, replacement part, adding and removing FAP from BSI and engine configs but nothing works.
The hardware and software numbers match perfectly on new and old ecu:
0281013332
9664257580
Can anyone shed some light onto why these codes are still appearing when they were not present before? I have attached the bin from the new ecu and also the file from the guy who messed up the ecu that he claims is the original but I cant verify that.
Any insights would be most appreciated!
