just bought the diff oil from bavarian autosport. they have them in stock and it was shipped to me within 1 week.
unfortunately,they charged me $50/bottle. i didnt read this public service announcement before i purchase. should have done a search on the forum before hand!!
this is what i got... i bought THREE 0.5L bottles. is this enough ? can anyone confirm?
