I am recently overhauling the interior and electricals on my car, and when pulling the relays to verify that they are the correct relays and clean them, I realized that the kickdown relay that was installed was from a 89 S4 not an 87 S4 that I have....is there a big difference...I noticed that the part numbers were different. I hadn't noticed any problems, so I am wondering if they are interchangeable? TIA

 

the relay that was installed was p/n 928.618.108.00, anybody else have any info. Thanks
