I have the same year and motor in my X. I did my guides last year. So from experience i found out that this in reality this is a nonsense double check step. Just make sure the vanos is turned all the way to the left (counter clockwise). There is a hard stop. This is where it should be. I didn't even test mine. Turn it a few times clockwise and counter clockwise to remove the oil from the vanos system. This oil will prevent the 0 ohm reading. If afterwards when you remove the GAS blocks from the back of the intake and the intake shifts, your vanos needs to be resealed. If you have done the timing chain guides, it doesn't take much extra to do the vanos seals. I would also recommend Beisan Seals. Or send them out to a Polish company Mehenker (you can find them on facebook) they rebuild them for a good price and also replace the black plastic ring. Read all of the instructions carefully and replace all of the pieces they recommend. It will make your motor quiet and return good gas mileage.
