I was under the impression that was only required for immo cars? Either way, which fuse are you talking about? as I have an 01 allroad I will be flashing one day soon.
It seems that the more I do the more I want to pull ecus out to flash them... I had a 2004 mk4 auto that I did a read over obd2 and had a error that I had to pull the ecu to rewrite to clear. before that I had numerous me7.1's I had issues writing to inside the car... for the amount of time it takes I find its well worth it...jmo but it works for me... I made a bench set up with a old 650 watt atx power supply, a ecu plug I cut off a junk car and a obd2 and to obd1 adaptor for my mpps cable / vagcom
