when changing the ignition modules should I change the coils as well?

no need to change coils.

It's better if you remove the coils and those two terminals at all and install 1.8T coils + harnes froma pikol

do the 1.8t coils do away with the modules?

The quote from the advert "When you change this Module, you should also change the Coils! It is a recommended, otherwise you will not get the correct Codes or reading from the ignition." is a complete lie. The AAN/ABY/ADU ECU does not get any codes from either the Power Output Stage (POS) module or the ignition coils. This is what makes diagnosing ignition problems so "interesting".

And, yes, the 1.8t coilpack conversion from Apikol (or as a DIY) eliminates the OE POS modules completely.
