Injection fault indicator

[Laurent]

I recently bought a '95 Dedra 2.0 16V.

From time to time the injection fault indicator (sorry if that is not the right English word) turns on. I went to a Lancia dealer and he tested the car. He told me that the error entry in the injection ECU can not be deleted but that the car has no problem... The only way to remove the error is to replace the unit, costing around 900EUR.

- First, I have a hard time believing that it is not "really" a problem: the ECU is monitoring some levels that are not in the expected range. Any indiciation of what it could be?

- Second, I have a hard time to believe that the ECU error memory cannot be deleted. Even if the error entry cannot be deleted, I am sure that the non-volatile memory (usually EEPROM) containing the error memory can be erased. Any help on how to do this?

Or any indication as to what could be causing this fault would be great! Thanks a lot!
