I have audi Q7 2007 with air suspension faulty not working. On the relay there is no power at terminal 30 when activated manually the pump is running but the car is not going up
My 2015 Q7 with 7 prong trailer plug (it’s actually it’s 4 prong) has no power coming to it. Removed the factory install receiver for the plug, no power coming to it? Any idea what my problem nay be? Thanks
