Ohhh okay so that pretty much cleared up my confusion as to why Bill was posting about somehting he no longer had as an option on his car
Bill time to get some soapy water on those little air bags in the rear to see where its coming from. I was going to say check the air lines going from the pump to the rear, but I dont think those would make the ELC leak.
Is there a diaphram valve at the strut that could go bad causing it to slowly leak?
I dont know im just tossing out suggestions, hoping to learn a little on the way as well.
