Probably depends on how long your arms are. :-) People have changed the entire coolant pump without removing the IM. Removing the IM just makes it a lot easier. But if you have jacks (I own QuickJacks) and can go from underneath, it might be easier (or not, depending on what's in the way suspension and axle wise).

Also, it appears the workshop manual implies you can access it by just removing the thermostat on the coolant pump, no need to mess with the entire coolant pump. So that's a big plus for you.
But if you're going to start playing with your engine at this level, you really should have the actual Audi produced workshop manuals for it. erwin.audiusa.com, pay for a day, VIN search, download all the PDFs for your VIN. This will all be in a doc referencing "1_8_2_0_ltr__4-valve_generation_II", but you want all the manuals. You never know when it'll say "remove piece X, as documented in one of the other manuals", etc. In the document list, hit the download square, not the view square. If it opens locally, then just save it.

Car still has a knock
camshaft adaptation intake bank 1 phase position is -2.46* so timing is okay?
Any chance it was bad gas or bad spark plugs?
Any ideas about the knock please? Thank you

"has knock occurring", no, I don't have any input on that. Are you concluding that because the knock voltages in the measuring values are high? Under what conditions? WOT, idling, etc. Could be carbon on the pistons, spark plugs, gas, etc. If there's not a diagnostic data to assess, you'd need someone to get in there with some actual troubleshooting.
