Yes, you are correct.

But I have found that seal rarely leaks. Usually the pump leaks from the Quantity Adjuster seal below it, which does require a Vag-Com to set properly.

Sighhhhhhh... I found today that it leaks not from the cover seal, but from the backside! Where the lower red arrow begins (on the pic) that ellipse shaped thing with two allen torx bolts - there is on the back of the IP on the same level one more thing like it, with two bolts, but it's flat, looks like some kind of cover (like the blockage thing for egr bypassing). It's dripping one drop per 3-4 seconds, only when engine runs. The place where it is located is reeeeeal pain in ...!!!... so probably I do need to do what I was most afraid of, to dismount the IP! But for now, I'm just going to make some drainage of the leakage, just to protect the coolant hoses... dismounting will wait.
P.S. I'm already getting tired with this... one thing you fix, another one already breaks down...

Welcome to the TDIDrip Club. I have 2 1996 TDI's in the driveway that are dripping.
Mine are both dripping from the o-ring where the 4 lines come out.
You can do some of the O-rings without pulling the IP (injection pump).

Once you get the bugs worked out they are great cars.
Also they say if you can get some Bio-diesel it will swell up the o-rings and the leak will stop.

Here is the 1st of the 7 videos to fix it.

Yeah, thanks PD41, but I've already been there Became a TDIDrip Club member in 2007 The IP was repaired with all the seals and washers... after almost ten years, still no leaks except this little pain in... Thanks for the videos but I'm not going to change seals (for now), it will do a specialist. No mistakes, no headaches.

Done. Today I made some kind of cone and attached a hose on it... the cone is now under the dripping place, and hose (4mm) is leading next to the oil pan. The coolant hoses under the IP are secured, for now (and cleaned up with brake cleaner). Fuel consumption will be slightly increased, but that's it... I'm tired from all these endless fixes on this already 21 year old pall of mine...
However, the IP goes on seal/washer repair when I'll have more time.
