The power loss is normal on hdi. The hdi ECU is one of the only 306 ECU that uses the speed as part of its calculations iirc. Sort of puts the car into a limp home mode. Bung a new sensor on there (cleaning won't do anything) and leave the battery off for half hour or if you know someone with pug planet, get them to clear the fault.
