Tire Pressure Monitor Valve (TPMS) - New Style
Discussion
Might anyone know where to get the "new style" Tire Pressure Monitor System (TPMS)tire valves at a cost effective price?
The new ones (the new cars have a different system) I think are made by BERU but I could be wrong.
Aston dealers want £75 each and they're quite a bit more expensive here in Switzerland.

I did not know there was a new style sensor, and as the BMW valve stem fits 06/07 cars then it might well be the old style. I think it is the valve stem only that is a BMW part for <£20, and they are slightly longer than the AM equivalent. The sensor bolts on inside the wheel. AM only sell a complete unit and I have just had one replaced, total cost including fitting was just under £200. From what I have read elsewhere the sensor incorporates a battery, which runs down over time.
I had a look in the Beru catalogue, but it doesn't list any TPMS for the DB9 / Vantage.
There aren't very many manufacturers for these things. Might be worth asking alloywheelsdirect.net if they can supply. I bought some from there recently for another car.
And £20 won't buy you a TPM sensor. Just the valve, although I would expect to pay less than that.

I got a spare set of wheels for my 997 and the sensors were cheapest direct from Porsche, alloywheelsdirect.net said they couldnt do a better price due to the volume Porsche buy off BERU, i guess it could be the same with Aston,There aren't very many manufacturers for these things.

It is a great system though !

You're a brave chap posting up a photo with mismatched tyre pressures. We have standards you know!It is a great system though !
Have they changed the pressures for later vantages as our MY07 are 33 front 36 rear. Or are yours all wrong?
It was a demonstrator they lent me while mine was in for warranty work !
On the porsche it was very noticeable that the side facing the sun or the wheels near the warm engine always increased more while parked.
Generally the pressures increased by about 4 psi after 10 minutes of driving.
As i said its a great and very accurate system !

Interesting on the +4psi observation. On the odd occasion that I've felt like checking pressures en route I normally reckon 37 & 40 so that fits just perfectly

I just replaced the Beru TPMS on another car. They are accurate to 1/100th of a bar. Impressive.
Cobblers (IMHO)Mine jumps around alot as the temp changes with a resolution of 1 psi
Also I work in the compressed air industry as sensor with 3 decimal point accuracy over that range is WAY to large and expensive to put in a tyre. They only need 1 decimal point accuracy as temperature changes make anything else pointless.
I've not compared the sensors between my two roadsters but the valves are exactly the same. (MY09 & MY12)

IIRC air pressure increases linearly with temperature.
Indeed it does
