Has anyone attempted it?

All Help Welcomed

Most folks who have the system end up disabling it. The system sensors can't be recalibrated to the pressures that current technology tires use, so the alarms become worse than useless. There are aftermarket systems with sensors in the valve caps that are easier to install and much less costly.

Disable it, it's not worth the headaches it gives, if you move from anything but stock wheels/tires.

I don't agree with the opinion given by rennlister above.

Mine works perfectly. For sure, you have to know that RDK needs ABS system working and all the system is subject to electrical worry. Electrical problem comes from connection. If you get a problem, check first all electric connections and second that the sensors are face to face with the detector.

Then probably the system would run all ways long.

Like I said, if you stay stock.

Besides whether or not anyone likes RDK, the question of retrofitting boils down to one of a) re-enabling RDK on a car that was wired for it (easy) or b) retrofitting RDK to a car that wasn't wired for it (theoretically possible, but only in a galaxy far, far away.)

Putting a tire pressure monitoring system on a car that was not wired for it is as easy as going to Discount Tire. Like Dr. Bob said, there are systems that go on the valve stem that work just fine. It won't be a Porsche system, it will be stand alone, and will do basically the same thing.

Those of us that have RDK typically disable it by jumpering the system so we can upgrade to other wheels.

It would be cool to hook up an aftermarket tire pressure system that integrated with the stock system so you could have the dash display of the stock system and the valve stem sensors to put on aftermarket wheels.

Richard, that sounds like a freaking nightmare.

The modern aftermarket systems are lightyears ahead of what came on the car. The little valve-cap transducers transmit tire pressure, enabling you to monitor actual pressure from the cockpit as you drive. Low- and high-pressure alarm thresholds are configurable in the system. K's 4-Runner even has a sensor on the full-size spare; That wouldn't help on a mini-flat spare like the 928 has, but it's still pretty cool. Can't imagine retrofitting the system to an earlier car on purpose when a better/cheaper/easier aftermarket system is available.

On a practical note, on your aging 928 are you really ready to mount the sensors, buy the 'correct' wheels, cut/splice/add in new wiring, a RDK controller, and then build some kind of alarm/display unit for the dash?

I missed out completely on the original question...

Simple answer is NO.

I have an active RDK system - Its OK. I also have a Smartire wireless sensor system which tells me realtime the individual actual pressure and temperature of each tire. I can set a both a warning and an alarm at any pressure/temp levels so its adaptable to any tires. The stock system warning display cannot communicate the individual tire temp/pressure info that the Smartire can generate - so at best it could be used to flag the alert/warning status per wheel.

I guess Simon means reactivate as I think his car is a '91, so the system should still be on the car.

The Smartire system Alan mentions is available in the UK, it was featured on Channel 5's the gadget show last year, about £175.
