LG AC gas oil choke ?

I have a 2 year old LG AC that has thrown up a CH38 error code for low gas issues.
The LG service engineer checked the gas pressure and found it to be ok. He released a bit of the gas and showed it having a slightly oily residue. He says the compressor oil has entered the indoor unit coil and 'choked' it which is why the gas isn't able to flow through.
His solution is to release the gas, which will bring out the oil, and refill fresh gas.
However he cannot say for sure what caused this. And no plans to refill the compressor oil.

Does anyone have a similar experience?
I have seen a few youtube videos on this, all by third party Indian techs, but don't see any official guidelines on this.
