Haynes will tell you that you need G50 75w90 oil from VW 1.9l for 020 and 02K gear boxes (or 2.2l for 02A - but these were only used for diesels and the 2.0 16v). I thought they replaced G50 with G60 oil but could be wrong?
Alternatively just go and get 2l of 75w90 GL-4 spec oil, most likely cheaper than VW pharmacy prices.
