The car has had a turbo fitted recently, but the garage didn't remove the sump. Fortunately they did remove the turbo feed pipe strainer, otherwise we would be looking at another new turbo as well. It is remarkable that the engine was still running at all, and tbh anothe 10 or 20 miles would have probably killed it.
It took the sump off, and removed the oil strainer completely, mainly to get it into some decent light in order to get a good look at it. The whole plastic assembly is held on with 3 Torx screws, and a clip onto the dipstick tube.
Once off & in some daylight, this is what I found inside .
This pic shows the rubbish picked up a little better, it would not wash out with solvent , but needed a good scrape
This was a clean cardboard box when I started, lots of shiney bearing bits in here , like glitter
This is what it should look like when clean, took about 20 mins , and 1/2 litre of brake cleaner.
Here it is bolted back onto the engine
Just a quick shot of the sump, which highlights how much the sump bung assembly prevents all the oil coming out when drained
After a new oil filter and a fairly rattly restart, the engine now sounds fine, and the message has disappeared .
Time will tell if lasting damage has occurred, but the car may as well be run to see. Car in question has done around 70,000 miles.
