I am considering buying an upgrade set of wheels for my 2007 V8 Vantage. My current wheels are fitted with the original sensors which work fine.
The wheels I am looking at are stripped down don’t have tyres, valves or sensors. I know how much new tyres are but can anyone tell me how much the metal valves and sensors for my year of car are and where I get them from.
I believe the Aston specific sensors are very expensive but they maybe interchangeable with Ford or Volvo equivalents?
I know I could strip my existing wheels but I’d rather not at this stage.

Thanks in advance

You might be fortunate Gareth, that your TPMS batteries are still working.
The system on my 2009 Vantage failed a couple of years ago (batteries I presume).

As a frequent checker of pressures, I decided not to fix the TPMS.
TPMS is not legally required on our age cars, so no problem with MoT.

Perhaps worth you looking in the FAQs sticky.
A reasonable cost solution has been discussed in detail on this forum, so hopefully you should be able to find the topic.

Thanks gents, I’ll have a look at the suggested links.

Just out of interest, when the batteries go flat in the sensors or they are not fitted at all, do you have the yellow warning light permanently lit on the dash or does it just not register?

If it’s lit can it be put out by reprogramming something?

This^^ ... Mine went on the blink and my car is 2009 but instead decided to buy the bypass gizmo from Aston Installations. Very easy to install and cheap. Not had a problem.

You will not find Ford or Volvo equivalents. Read the old threads for the solution if you want to retain Smartire TPMS.

How did you know it failed? A specific Warning message? I had a tyre pressure warning on the way to Le Mans that cleared itself, so now I’m wondering if it had failed or just “glitched”. As you say though, doesn’t matter of it has failed as I check them every so often anyway

They can glitch from time to time. Mine did on the weekend due to doing a u turn across grass and dirt. It went away after I restarted the engine 10 mins later. Was ok after that. It also happened occasionally in my DB9

Yes, a warning message, think stating 'TPMS Fault', displayed after each engine start.
The message can be cleared, but the amber fault symbol remains on.

Your warning was presumably not the fault message, but informing you that a pressure was low.
I guess as the tyre heated, pressure increased and the warning went off.

I think the sensor battery problem can be sorted (personal choice for pre-2014 cars). Just need to find the topic, or pay a huge amount to AML for a new sender unit and programming.

I can't speak for your model year (I'm not sure when the switchover between Beru and Smartire systems occurred), but there are a lot of less expensive, perfectly reasonable aftermarket systems available for most cars, now.

Recently I found myself in a similar situation to you, having bought new wheels for my '15 V12VS. I decided to proactively install new sensors as the typical battery life is rarely more than 10 years. I received an absolutely egregious quote of $2,000 for a new set of OEM sensors from a nearby Aston dealer; I suspect he can still hear my laughter when he picks up his phone. My local indie sourced me a set of aftermarket (I believe Bosch) sensors for less than $400. They have worked flawlessly.

You can normally get the aftermarket ones and clone your originals, then just swap wheels at your leisure just resetting the tpms pressures

Thanks Chaps, Seems there are a few options that don’t need to cost a fortune!

When my TPMS was working, I had thought about doing an experiment by letting out some air. Never did it though.

How many psi reduction is needed, to trigger a TPMS alert ?

Depends if it’s an actual sensor or works off the abs

A dead giveaway of impending failure is a warning message from one sensor on a cold morning that goes away as the tyres/day heats up. Indicates battery voltage in sensor is close to lower limit. The minute this happens do not delay replacing the sensors..its much easier to clone new sensors off working old ones. And yes lots of threads on this topic and a very cost effective and satisfying DIY job
