Oil filter Mann or Bosch

Pracuję przy niemieckich samochodach od ponad 40 lat. Wiem, co działa, a co nie. Czy chciałbyś podzielić się swoją opinią na temat tego, dlaczego większość [jeśli nie wszystkie] niemieckich firm samochodowych polega na tak zwanych „gorszych” produktach? Niestety, opinie takie jak Twoja opierają się na opiniach, a nie na faktach. Gdyby były tak gorsze, jak mówisz, typowy niemiecki silnik nie przetrwałby okresu gwarancyjnego.

installed a Mann filter. torqued the filter housing and noted the paint dot on the filter was tightened to the same location as before i started.

So my car has 86k on the clock and its an Edition 30 GLI. Great car by the way. I service it every 5k with Mobil 1 0W-40 Euro Formula (502.00 spec) with a MANN filter.

The 30 is the way to go. It's better in most every way and is not that much more. They use a better filter media and seals for a longer service life.

Mann & Mahle filters aren't all that expensive and since needing them won't be a surprise type event; buying them can be scheduled prior to need.

I typically use Mobil 1, Valvoline, or Pennzoil fully synthetic 5W-30; whatever is on sale. I use a full synthetic and change it every 5000 miles.

Use a good quality oil filter too (not Fram). I typically use Napa Gold, Wix, Mahle, or Mann

I typically use a Volvo/Mann filter, with 4K intervals.

You should stick with the OEM filter, made by Mann or Hengst. You can buy at VW dealer or Amazon.

Mann is OEM to many manufacturers. Since I've been fixing German cars for 35 years, I'm pretty certain I have seen more used oil filters that you ever will. As a diagnostic technician for over 20 years, I bet I cut open more oil/fuel filters too. I have never seen a factory [Mann, Hengst, Mahle] filter not do their job in the time/mileage they are suppose to do it. I have seen them fail after 40k miles, but that is not what they are designed to last.

After much searching and reading DIY threads, I didn't see any mention of springs for the filter. Your replies confirmed it so I was confident enough to throw the Bosch setup in the trash.
