Retrofitting TPMS to a 2009 Cayman S

Joe!

It is possible, but a lot of faffing. You would have to fit the TPMS control unit (RDK in Porsche-speak), the 4 sensors in the wheel arches, wiring each sensor to the control unit, and of course the wheel sensors. The control unit needs a switched feed and earth, and 2 wires to the Comfort CAN bus. Then you need to code the Gateway and Instrument Cluster to add TPMS. And Bob's your uncle..... Edit: Drop me a PM with your email address if you would like the wiring diagrams.

 
Hey all, does anyone know if this is possible? I know you can get bluetooth valve caps etc., but really want the proper TPMS on board.
 
Do you know if there's anyone willing to undertake this work and what it might cost to do?

 
Thanks for the welcome :)

That does seem like quite a lot of work, any idea of what kind of quote that'd be? Seems in the £1k region.

 
You are looking at about £1000 for parts, and it would be a LOT of work. It would also be a challenge finding someone to take it on. I would look for an aftermarket system if I were you. I fitted one to my 996 Turbo, and from memory it was about £150.

 
Hi Richard, can you suggest the one you got? and where did you buy it? Would be nice to know a reliable when it comes to aftermarket

 
Mine was an Orange Electronics P409S system, I bought directly from Orange Electronics in the USA at the time. As it was some time ago, I expect there are newer and better ones around. However, I did find it on Amazon:

https://www.amazon.co.uk/Orange-Monitoring-Transmitter-Diagnostic-Temperature/dp/B01IB8CMDA/ref=sr_1_1?s=automotive&ie=UTF8&qid=1509532768&sr=1-1&keywords=orange+tpms

The later model shown on Amazon also displays tyre sensor voltages, which mine didn't have, and is a useful feature. Bear in mind that you'll have to factor in the cost of removing and re-fitting the tyres, if you aren't fitting it when you are renewing tyres. I also recall Orange supplying some different valve stems (shorter??) to fit the Porsche wheels, so check that whatever you choose are compatible.
