We had 09 308 where the TDC was not triggering the ECU, advised by Peugeot and that was the only reason we swapped BSI and ECU. Keys can stay as original but swap out RFID chips or motherboard on the switchblade remote.
Should be plenty of 308s at the wreckers that are suitable. Pull the ECU and confirm part number
We have a fault in the ECU and the Electric Water pump for the turbo is now not working. Have been advised by Peugeot dealership that we need to replace the ECU and if we replace with 2nd hand unit need to also replace BSI, keys & cluster. Have tried several wreckers however can't seem to locate these items for a manual
This is the part number you should ask wreckers for. Any 1.6 petrol 5FX engine with manual gearbox 9666104380
Should be plenty around. There is a company on AU selling the whole kit for $900 but pretty expensive exercise
