Default Re: Help with HFS-4 v3 setup on BMW Z4 35i (E89 N54)
Thanks Richard. I have wired as per your updated page. However, as my car has comfort access the HFS-4 powers on briefly whenever I open the car and before getting to ignition on. From the HFS-4 instructions, the unit is not meant to power up until the ignition is full on - 2 press of the start button.

Therefore the power on process is not always the same. Sometimes when it powers on the gauge lights representing flow turn on up to the 50% mark and then run back to 0. Other times the gauge backlights light only. Can you please advise if I need to change anything?
