When a failed Audi A4 air conditioning compressor is replaced by a new Audi A4 a/c compressor, it is so important to have the lubricantdistributed evenly across the Audi A4 air conditioning compressor and the Audi A4 a/c system before engaging the system for the firsttime.

If this is overlooked and the Audi A4 air con compressor is engaged immediately after is has been charged withrefrigerant, it may happen that all the oil in the Audi A4 a/c compressor will be pushed out all at once while thereis no oil yet to enter the Audi A4 air conditioning compressor on the other side. This is caused by the fact that it takes sometime for the oil to spread across the system and mix with the refrigerant. Eventually the Audi A4 ac compressormay be damaged because of a lack of lubrication during the first few minutes of operation.

This will of course be more problematic after the system has been flushed, this will mainly be thecase after the Audi A4 air con compressor has suffered a catastrophic failure with metal particles from the Audi A4 a/c compressorbeing spread across the entire system.

Generally new Audi A4 a/c compressors are supplied charged with oil, but it is always recommended that youcheck this by draining the new Audi A4 air con compressor to check the amount of oil in the Audi A4 air conditioning compressor.

Then once you have removed the old Audi A4 a/c compressor you should do the same again, empty the old Audi A4 ac compressorof oil to see how much oil was in it and then fill the new Audi A4 air con compressor with the same amountthis is to avoid over charging the system with oil.
