Hello sir. I’m working on 2002 Jetta tdi. Wastegate Atuator won’t hold Vac at all. Bench service/test. Appreciate any help. Your Videos are great. Thank you for sharing your skill set. E
If it wont hold vacuum you'll have to replace it. if its been like this awhile the vanes may be seized. Pull the actuator off and see if the lever moves.
Yes cleaned it as shown in your videos. All’s great. Do you have them? Oh. I’d never film it, but it did come out up top. Your way is “The Way”. !! Didn’t have Hex large enough for axel.

Which is worst to work on vw or Mercedes?
I don't work on enough mercedes to answer, but my tech service had real good info on this one.. We were able to diagnose it in a reasonable time. Parts cost on mercedes is a little ridiculous.
