Tyre valves

[coolcol]

having had some new front tyres fitted to my v8v the fitter said i will need some valves next time i change my tyres any idea where you acquire some valves from any help would be great cheers

It's a good question as if you have the TPMS you can only buy the valve and sensor complete from a dealer, which turns out rather expensive.

I've seen a few places that sell replacement valve bodies but whether they fit the Aston sensor is another matter. Anyone?

Alternatively if you don't care about the TPMS then just have the system disabled and ask your tyre fitter to fit regular valves.

So are the sensors / valves a consumable item? This would add about 50% to the cost of replacing the tyres + coding labour as well.

I do recall someone having located replacement stems but can't find the linky.

Not really, but if the tyre mechanics are not careful then they break or disform quite easily.

My wheels are currently being refurbed, and I got a call that the valves are corroded. Apparently the sensors bolt on underneath the valve body and these are usually OK. It is the valve body that corrodes and there is a BMW part at approx £15 each. The link is http://www.pistonheads.com/gassing/topic.asp?h=0&a...

Thanks to mjk1

+1 and they were very cheap IIRC

[coolcol]

thanks for replies but cant seem to track down that part number from previous topic but i found this site http://www.alloywheelsdirect.net/option/tpm_sensor... which sells the valves but not sure which ones will fit.

[Lunablack]

If you just want the valves....they are part No 43LMS11,3 made by a company called alligator...

I've bought them from here in the past?... Came to less than €20 euros for 4 of them...

The BMW part number is in the link I provided above.

Quote: [i]Having reported earlier in the thread that I was having my V8V wheels refurbished by The Wheel Specialist in Burton I'm now in a position to give some feedback. I'd taken the wheels off myself and didn't get chance to put them back on and make sure the tyre pressure sensors were still working until yesterday.

Well everything was fine and the wheels now look like new again. Would have no hesitation in recommending this company. It all started fairly badly on the first morning when I got a phone call to say 3 of the 4 valves were seized and in the past someone had done a shoddy weld repair to one of the front inner rims. Thought I would be looking at a huge bill but by the end of the day I'd had another phone call to say they had sourced some valve and sensor housings from BMW allowing the sensors to be reused. The cost for 4 was £55.49 and the BMW part number 36.46792830. Aston only sell the whole assembly including sensors and valves for many hundreds of pounds!

The weld repair was redone and the welders initials stamped onto the rear of the hub of the wheel showing they stand by their workmanship. The cost here a very reasonable £35.[/i]

The cost of the refurb itself was £408 which isn't the cheapest around but nothing was added for the time it must have taken trying to remove and then cutting off the valve and sensor. I went for the low fleck Hi-Power Silver finish as it is the closest to the original finish. Time will tell how durable the finish is but I doubt it will be any worse than the original which were suffering significant amounts of corrosion after 5 and a half years.

I've linked this thread to the FAQs so the info is easy to locate when I need it!

Has anyone worked out if these valve stems fit the newer version of the TPMS system?

[Jockman]

It's on my list to do, matey.....along with world peace...inter alia

[mikey k]

Are you getting wet in the Wirral or Snowdonia?

[Jockman]

Both - came back yesterday. We were heading up Snowdon until we noticed that black cloud on its summit

I've just had to fit new TPMS unit to front nearside of V8 Vantage, 2008. Do I have to go to dealer to connect thru to computer or can I do this? Newbie

Can't give you a definitive answer but you can try driving the car for around 15 miles or so during which time the sensor should pairs with the module. If it does and the life go out then great. If not then it's looking like a trip to the dealer.

[CheekyChino]

Thanks for response, just did 30'ish miles but not talking to computer. Looks like I'll be adding to local dealer's turnover.

I have recently replaced the valve stems when having new rears fitted. Don't know if there has been a change of stems through the years though but I have a 06MY V8V and these fitted fine.

Here's the link from Aston Bits.

Only advice would be to retain the grub screw that locates the stem through the TPMS unit from the original stems as the replacement ones are pretty flakey. Be careful not to cross the threads on the locator collars on the outside of the rims as these can strip when you tighen them.

To add, remove, disable or change a sensor you need one of these or a trip to the dealer;
