Electronic Parking Brake

I'm the proud owner of my first Porsche in the guise of a 981 Cayman S with PDK. It's fabulous in every way except the irritating stop/start and an odd (I think) issue with the parking brake. It works fine, just as I would expect except the (P) light does not light, but rather the (!) brake light. I know it's just had new rear pads fitted. Is this something to worry about? It has 24 month Porsche warranty, but the dealer is 75 miles away.

Any advice?
 
Hi, and welcome to the forum!

You've got a great car there and I'm sure you will get fantastic enjoyment from it.

I have the standard 981 with PDK but the functions are the same.

As regards the parking brake- what you are seeing is correct. When activated, the red (i) light comes on.

The orange (p) light operates if you try and pull away and auto disengage isn't operable, or if you need to activate emergency braking by pressing and holding the parking brake button while on the move.

I find the Start/Stop very annoying as well. It's operation is designed to defeat its intention - that, as soon as you release the foot brake, the engine restarts. So, considerate drivers who set the parking brake after a time to avoid dazzling those behind succeed in the engine restarting needlessly. One can see that they do this to prevent a pause when pulling away but it is annoying nonetheless.

I presume you have seen the switch on the console below the manual spoiler switch which defeats the Start/Stop? Unfortunately it also defeats the coast function in PDK cars. Also, setting Sport mode defeats Start/Stop.

These button settings do not persist after an engine restart, but if it is a big issue for you, an American company called T Design offer a small, easy to fit module that remembers settings and preserves them.

I don't have one, but do have their phone holder which works well.

Have fun!

Neil

 
You can change the default setting of the stop/start by a coding change using a PIWIS tester. The optrions are default on, default off, or remember last setting. I have done it a few times for 9x1 owners. If you are anywhere near me (Maidenhead, Berkshire) drop me a PM and I would be happy to do it for you.

Thanks Richard! You would think 'remember last setting' would be the default if the facility is there!
