I had to disconnect my Cayenne turbo's battery to install new fuel pumps and related things. I had this problem (suspension) when I bought this pig. The suspension faulty workshop notice and while working on changing values, I get the consistent accumulator charging, but only in park? If I drive 20 feet it no longer says accumulator charging????

I was able to get it back to normal a few years ago, but for some reason, the Durametric just won't read the 1st FL value. The FL is very low and the RR is very high. Trying for about 8 hours and no luck.

Any suggestions? The factory module resets to some crazy setting if the battery is disconnected, and, if you have used Durametric for lowering/adjusting, you may know my frustration.

Any advice would be appreciated. I have done everything I can think of. It's an 04 Cayenne Turbo

 

Now I just keep getting "error reading data" on Durametric adaptation when I hit "read" on the 1st FL. Nothing is adjustable after that. What is the solution? It worked fine until I had to detach the battery. I have been trying for 2 days to correct this. It still raises and lowers all the way, but not evenly. Now what?
