hi i am new to this forum, can i ask for your help/oppinion on my 307 sw (2 ltr hdi)
i keep shutting down into limp home mode with anti pollution faults and esp faults.i have plugged it into lexia 3 (pp2000) and it keeps comming up with esp cannot cummunicate with ecu (pp2000 unknown and ecu is being referenced) it looks to have lost comms somewhere, i have checked all fuses, abs ecu has been sent away to be tested and has come back with no faults, rear a.b.s sensors have been changed and still no joy.It will not even allow me to do peramiter check (live data), it allows me to read faults and just says unable to respond with ecu (i click into to info) and it is all happening when car is stationary), just to add aswell car did have a bump on front passenger side wheel and damaged wishbone (which has been replaced and i have re calibrated steering angle sensor)
also when i plug diagnostics into car and it keeps comming up with wrong vin number and i have to cahnge it (otherwise the diagnostics thinks it's a 307 van) i ave to change it to hrh. then it will come up with single chassis car.
the fault codes i am getting with anti pollution is mainly to do with turbo pressure and are all intermitant (i am sorry but i can not remember all fault code details to hand)
i have done a forced regen on particular filter on exhaust, topped up ely fluid(which is still showing too low on diagnostics, even though i put 2ltrs in), reset counters on ely fluid ecu. pressure differential sensor has been changed (as old one got water inside and nakered sensor) for some reason aswell upsteam and downstream sensors don't add up (reading quite off from each other) even when car is cold (reading 156 degrees c)
could you please help? kind regards danny
