Is there any way to get rid of the tyre system warning.
Discussion
Have changed the wheels on my 2008 DB9 and the warning light and message is permanently on. They haven't put the sensors in the new wheels as one of the m broke but frankly the system is a pain in the arse anyway so i'm happy not to use it.... but how do you switch it off/disconnect it?
From previous thread:
I hope that helps

So here's the deal to extinguish the dash messages:
1) Disconnect the TPMS at the connector block under the dash (white connector).
2) Identify the 4 wires on the car-side of the harness: these should be red, white, black and blue/red.
Blue/red is 12V switched power
Black is ground
Red is the TPMS system fault line
White is the tyre low pressure fault line
3) At the car-side connector half, short the black, red and white pins together, using whatever technique you are comfortable with. This will tell the dash warning system that everything is OK with the TPMS and that none of the tyres are underpressure.
Myself, I just cut the mating connector pigtail off the back of the TPMS module (in the middle of its length), cut the sheath back, and then twisted together the Orange, Brown and Black wires, leaving the Red power wire untouched. Since I don't particularly like soldering because of the chance of getting a cold solder joint, I just used a small wire nut to twist the 3 wires together. If I ever want to use the TPMS system again, I can undo the nut and splice the connector back on to the TPMS pigtail. Then I just plugged the connector back into the one on the car, and voila, no more dash warnings.
Just for clarity, the Orange wire on the TPMS side corresponds to the Red wire on the car-side of the connector. Brown corresponds to White, Black to Black, and Red to the Blue/Red, respectively.
If this isn't clear, let me know.
If you just disconnect the TPMS unit you still have the dash warning light, if you do the above the car does not see a fault so no warning light. You can't pass the MOT with a warning light showing, so the above is a necessary work around if you want to permanently disconnect the TPMS or if you want a bit of time before getting it fixed.1) Disconnect the TPMS at the connector block under the dash (white connector).
