Cayenne TTS (521HP) Air leak ??

[Peter_Ch]

Hi

I have Cayenne 2006 TTS.

Month a go i got P2179 & P2187.
I repaired T-LINE below throttle body, changed vent line from left turbocharger to 3 way valve, checked air-oil separator and all vacum lines, changed all seal rings from air filters through turbochargers to throttle body even seal ring under throttle. I changed also two oxygen sensors for new OEM Bosch
I cleaned throttle and did adaptation using basic settings
Both MAF's are still old and i haven't clean or changed them yet also EVAP valve is old 
Of course all spark plugs and filters are new

Now all errors in DME dissapered but i have still rough idle speed in the morning for 30 seconds, after 30 seconds engine works smoth, there is power etc ..
I think that i should reboot "handover" DME but in Durametric i can't find "basic settings" for RKAT, FRAO, FRAU (long&short time fuel trim) etc ... 
Is possible to do it using this tool or just disconnect battery for night like in 986 & 996 ???

I put screen from durametric from today morning. FRAOb1,b2, FRAUb1,b2 and RKATb2 are pretty ok, but i am not sure what with RKATb1 on passenger side ?? 5,3% ??

Regards

Peter

"Handover" is not possible with the Durametric system, but disconnecting the battery should force the DME into a "relearn" cycle.

Thanks for reply, do you think i have to connect two wires "+" & "-" together or just disconnect one of them ? As you know in Cayenne battery is under driver seat so i would have take off this seat, but i have idea to disconnect "+" of battery in small hole near gass pedal ?

You should only need to disconnect one battery cable, which ever is easiest to get at, it is not necessary to touch the cables together.  Just be careful working with the positive cable away from the battery as it is hot and can arc easily.  Normally, we suggest disconnecting the main ground as that will have the same effect, but eliminates any chance of an arc.
