Rear convenience system control module

[bigfoot007]

Hi,

Just ran a test on my 2003 TT and came up with the following (amongst others)

1330:Rear convenience system control module - No signal/communication, test conditions are not-completed, fault is not currently active and is not causing a DTC light

All the systems from the unit seem to be working OK. I looked into the POSES and it says for the 1330 error to replace the unit, strange if everything is working. Has anyone else had this issue?

The other code is:

1517:Trailer hitch control module (AHK) - Upper limit value exceeded, test conditions are not-completed, fault is currently active and is not causing a DTC light.

This I think is also part of the Rear convenience system, but again the trailer hitch moves in / out when the switch is operated.

Is this adavnce warning of an iminant failure?

Thanks in adavnce.

Have you recently replaced the battery?

I would clear them and see if they come as sometimes you get false errors when replacing the battery.

not replaced the battery, the codes are cleared. I will check again at the weekend

I am having an issue where my comfort settings in my 2003 cayenne turbo keep getting reset when i switch between my 2 keys. If I stick to one key it stays programmed. I have read some older posts that I either need to update my convience module or get a new one. If I find an updated one, does it require porsche to program a new module to the car or will it just work

Both keys need to be programmed by dealer at the same time.

I'm having trouble with check tail light warning I hit the brake, it led 2008 type rear cluster and I've checked everything and narrowed it down to when voltage is 13.2v then it will always trip the warning on dash, if you turn lights of and on again warning disappears until again you hit the brake.

Im convinced I will have to change the comfort module to fix this and coding. I didn't think about the keys as well, so I hope my independant garage who has Piwis is going to be able to complete all the programming.

Has any one got experience of this and fixed it? There must be someone, pls hit us up with your knowledge wealth.
