Default Oil pump "lifetime" belt

I looking to upgrade my 06 Jetta tdi to a Passat. I've been doing some research on the new ea288 engine. 130,000 service interval on the timing belt is a good thing. I'm just concerned about that oil pump drive belt that runs in oil. What happens to people that own these cars up to 200-300,000 miles. Can't believe that belt will run that long. Can't be an easy job servicing that belt. Anyone seen or worked on these engines yet?

I have 230,000 miles on mine without any issue with the oil belt.

That's on the 2015 model only. New and improved engine over the 2014 and older. Lots of changes.

Nobody will have any long term info regarding the oil runner belt on this particular application, however Honda's GX/GC engines have been using them to run the camshaft for a decade or more now, never heard of any problems with those.

All just down to material choice. Once you have an oil proof elastomer, the mechanical conditions are very favourable — lots of lubrication fluid, one material much harder than the other and the softer being resilient as well.

Change the belt when the TB is done? OH, how hard is it to change the oil pump belt?

Never done one, LOL.

Book time is 3.5hr for both the drive belt OR the pump, but it sure looks like it would take a lot more time than that, due to the dual oil pans both having to come off.

I think 10 years from now we'll laugh about any concern over this oil pump drive belt, since I'd bet 20 other things will be much more common to have to deal with.
