My 04 Cayenne S is throwing 2 codes, no CEL.

DME:
907
Load management operat. on vehicle
electrical sys./DME control module
Present

No other codes or engine miss, slight tick from engine??

Coils?

Other one is the Air suspension, I get the "Faulty message" on startup now and than. Code is:
1772
Signal lead for pressure sensor
Pretty sure I can solve this with the VW Compressor rebuild kit.

 

Do you still have a FACTORY Porsche battery still??
P!gs hate low batteries.....

I do not see a DME 907 error listed, but it sure sounds like the battery is toast

Off to a shop with a PIWIS I go!

 

To resurect this thread. I had the occaisonal Workshop fault with code 1772 and did the complete compressor rebuild (the rubber compressor piston ring was definitely hardened) but it didn't solve my problem so I'm going through the troubleshooting phase starting today. The suspension seems to work normally other than the fault. I did find this Touraeg TSB which may help some as the parts seem to be all the same. Comes on every time about 1 minute after startup.
