and don't think that a really small amount of oil ( not the ND11 ) will brake the prius compressor.

Here is what the shop manual has to say:

DESCRIPTION

The DTC is output if there is insulation trouble with the high-voltage circuits in the air conditioning system.
Insulation trouble with the electric inverter compressor or A/C inverter may be the cause. Any oil other
than ND-OIL 11 may have entered the refrigeration cycle.
The motor driven with high-voltage is built into the electrical compressor and is cooled directly with
refrigerant. Compressor oil (ND-OIL 11) with high insulation performance is used because a leakage of
electrical power may occur if regular compressor oil (ND-OIL 8) is used.

NOTICE:
• Electrical insulation performance may decrease significantly if even a small amount of oil other
than ND-OIL 11 is used or enters the refrigeration cycle, causing the DTC to be output.
• If other oil is accidentally used and a DTC is output, collect the oil in the refrigeration cycle into
the compressor and replace it with ND-OIL 11 to increase the ND-OIL 11 ratio amount.
• Replace the main components (evaporator, condenser, and compressor) if a large amount of oil
other than ND-OIL 11 enters the system. Failing to do so may cause electrical insulation

performance to remain low, causing the DTC to be output.

I just did my 08 ...the nd-11 oil is over $100 for a tiny can ....I changed my condenser and used 1.4 oz ...its like $10 a tablespoon...........

yea its real expensive, you can just pour it into the compressor if you take out the high side line from it, dont ever get a drop of the ester oil in there, your going to ruin your entire a/c system.
