Replaced PSE Pump, Horn Chrips when Ignition in Position 2
I just replaced my PSE pump (new OEM part from Germany) today in my 98' SLK230. My original PSE was not worth saving (broken resistors on circuit board, extensive corrosion etc..). Everything is now functioning correctly however, when I turn the ignition to position 2 the horn chirps! It seems like it is doing some sort of safety check.
I have read somewhere that the PSE pump may need to be 'coded'?
Anyone have any idea how to disable this horn chirp?
Any advice is appreciated.
