It sounds like they are inspecting the oil pan for signs of metal shavings indicative of possible metal loss from engine bearings.
It should be progressive because if you shave off enough metal, the bearing will completely fail.
If there are no metal shavings in your oil, then the issue should not progress because it is not present.
You should replace the bearings if faulty and there is no other damage. Otherwise, you should replace the engine.
Interestingly, the recall report states that the ECM of the 3L engine will be reprogrammed but the 4L will only have the oil replaced if they are found to be good engines?
Are they decreasing performance on 3L engines to match the lower than expected performance of the bad bearings so the engine doesn’t fail?
I would be very interested in what you think about LMMS. It reminded me somewhat of FL Studio, but like I said I wasn’t really good at it so there may be features you’re lacking.
I have to say, the audio situation used to be a bit of a mess but it has gotten somewhat better.
