SRI reset Cayenne Instrument cluster (7L5 920 875)

[loulouton]

Hi everyone,

I continue to analyse the VCDS possibilities with the 9PA1 Cayenne (957) and specially regarding the SRI reset.

Here are the only adaptation channel available for the Instrument Cluster (17):

Channel 02,0,N/A,N/A,N/A,N/A, ==> Is it the service indicator that is set to 1 when the service need to be done? (to be reset to 0 to reset SRI?)
Channel 04,3,Language, , ,-, ===> Language : French
Channel 09,9852,Kilometer,in 10,km,-, ==> The current mileage
Channel 30,128,TankSensor, , ,-, ==> ??
Channel 35,15,N/A,N/A,N/A,N/A, ==> ??
Channel 40,108,Actual Value,Insp. in 100 km,-, ==> My car needs service in 10800 kms...
Channel 41,214,Actual Value,Insp. in 1,Days,-, ==> ...or in 214 days
Channel 43,30,Max. Value,Oil in 1,000 km,-, ==> Max km between service = 30000 km
Channel 44,730,Max. Value,Insp. in 1,Days,-, ==> Max period for service = 2 years

I don't see a way to switch from long life to fixed period service

Do you think setting channel 40 and 41 to max values and setting channel 2 to 0 will perform a SRI?


In addition I noticed that there is a Channel 0 and the description is "Saving channel 0 reset the instrument cluster to factory default". Is it a (hard) way to perform a SRI reset?

If this were a VW Touareg cluster from roughly that time:

Channel 02 would set itself to a non-zero value (typically 1) when service is due, and you would reset the service reminder by stuffing a 0 in there. When Channel 02 contains a non-zero value and has a zero stored in it, changes to 40 and 41 should be automatic; you should not have to do anything there manually.

Channel 40 would be the distance that the vehicle has been driven since it was serviced, not how much distance is left before service is due. You may wish to observe if the value in this channel increases or decreases as you continue to drive the vehicle.

Channel 41 would be the time since the vehicle has been serviced, not how much time is left before service is due. You may wish to observe if the value in this channel increases or decreases as time continues to pass.

Channel 43 would indeed be the maximum distance to service.

Channel 44 would indeed be the maximum time to service.

Now whether this Porsche cluster behaves like a VW cluster? I really don't know. I suggest you observe and experiment.

Thank you for the answers.

Indeed channel 40 and 41 are values since last service and not remaining values until service, because I know my last service was in oct '13 so this fits with the 214 days.

The behaviour of this cluster looks like "old fashion" and similar to the one I practiced in my first 2001 audi a3. However I remember that there was a possibility to set the oil "quality" to choose between longlife or fixed interval.

I really wonder is the longlife or fixed interval setting is in fact hard coded in the Cayenne cluster and I guess there are several versions of the instrument cluster...Or maybe this is through the coding that the config is done.

The chart at the bottom of this older VW Service Interval Reminders page and Channel 45 may be worth looking at.

Thanks Dana.

There is no channel 45 available

I'm waiting for the service and I will update the thread with my experiments.
