I had the same problem. So I had to raise my TPC settings up and then I increase the pressure to make it happy. I am now going to lower it back and see if it gets pissy with me. I had it lowered down to 33/37 before I put nitrogen in it and it didn't fight with me. So I hope to get it back. I hate it being too high.

 

My manual gauge shows 30/34 and TPMS seems happy and accurate for now.

 

i just emailed my porsche dealer to see what they say about this, because adding pressures until the TPC is happy just doesnt seem correct or safe because the tire pressures at all four tires will vary. I will inform once I hear from them.

 

Looking forward to hearing what they say.
I was going to call my dealer but i'll wait for you.

 

alright guys, the head mechanic told me to increase my tire pressures by 4psi at all four corners and to reset. will try this and see if this works.

 

So Front-33, Rear-34 and re-set.
I'll give it a try.

 

Ok - Did It Work Or Not Please?

 

Yes it did. Mine is perfectly happy now.

 

Thanks for your response!

 

All seems ok now.

 

There is a discussion thread going on in Rennlist 997 GT3 forum right now about this very thing. A member said that you needed to have the TPMS unplugged when the dealer goes through the process to disable it. More information is avialable on Rennlist.
I was at the dealer last week and I asked them to disable it before I had this information. They tried but were not successful. I will try this new approach. It is a very annoying system that does not give accurate information. I used to be a big fan of it but it is too annoying when you are tracking a lot and running low cold pressures.

 

I saw that link. It is annoying on the track, but if it isn't a your dedicated "track car" then you might be better off leaving it in. Atleast we don't have that silly alarm like the canucks.
