Sludge

Thanks for the backup! I know the internet is full of people who just spout off whatever they feel like so it’s hard to trust anybody. It’s nice to be confirmed so maybe those reading can see that this is trustworthy information.

I'll add a big 2nd to everything Cody is stating. You can theorize all you want about the 1.8T sludge issue, but those of us who have dealt with it, know what you are up against. I've seen it in every year of 1.8T, fixed most of them. This also includes the transverse mounted engines in beeltes/golfs/jettas. Far more common on the longitudinal mounted ones though.

There is no way around it other than pulling the pan and cleaning or replacing the pickup tube. On the early ones where the tube can only be had with the pump (early 2000 and back) I clean the screen. Just did one about two weeks ago. On the later ones, youcan get the pickup tube for $30 or so, I just replace it. There is no amount of flushing that will get the stuff out otherwise. No magic chemical, etc. Brake cleaner will break it down, but do you want to run that in your bearings? I think not!

Think of a house screen, only metal. Then plug the holes one at a time with grains of sand. That is essentially what we are talking about here. It's not really the classic "sludge" that you are used to seeing. It's more like small (and very hard) carbon particles.

Proper oil changes with quality oil, proper turbo cooldown. Critical, and the only way to avoid these issues. Most people don't do both, many don't do either :( After I clean their engines, I teach them this, so it won't happen again.

2nd this BTW vvvvv. I've got several customers with 150k+ on early 2.0T's, clean as a whistle in there.

  It seems that that issue was resolved, I've not seen it yet and that includes some pretty high mileage cars.
