Yes it is possible, you need to convert your ignition and lighting to canbus so the unit powers up and illuminates correctly, you already have gala so feeding a speed pulse is easy. and you have an A6 unit by the sounds of it, but I think you mis quoted the part number
4B0 035 192P is the A6 unit
There are adaptors available on ebay with can bus converters built in to give you the can signals you need.
I think this is such an item....
