Damaged valve & valve stem replacement

Post by Nico56 » Sun Sep 27, 2020 3:14 pm

Hi
A "rookie" mistake I know but our 'new to us' 2018 plate Corsa 1.4T had metal tyre valve covers with the VH logo on their tops. The tyre pressure warning light for the driver's side rear wheel recently came on and so I thought I'd put a bit more air in to sort out the problem. While trying to do this I think I have now caused a bigger problem since when I was removing the valve cover ( - which came off really easily - ) it brought the top half of the valve stem with it. See attached photo.
I have seen some posts about corrosion issues caused by fitting metal valve covers on TPMS valves and saw one post that implied the TPMS unit fitted to each wheel was composed of two separate parts. Presumably the valve / valve stem and the transponder component. Les anyone know whether it is possible to just replace the damaged valve and valve stem rather than having to replace the entire TPMS unit as a whole?
Thanks

A tyre shop should sort it for you, when you change the tyres they will remove half of it and use a new valve. The sender should be fine which is inside the wheel.

Thanks for sparing the time to reply......Does anyone have a link to the CorsaE workshop workshop manual? I'm hoping this might show the OEM part number for the TPMS unit and have details of whether it's components (ie valve&valve stem and the sender unit) are available separately or are only available as a complete unit?
The car is still under the original VX 3 yr warranty - though I'm pretty sure this won't cover the damage I've caused myself in trying to remove the siezed up valve cap. Anyway, I don't want a VX main dealer to try to twist my arm and make me buy a complete new TPMS unit if this is unnecessary
Thanks again

You can get a new genuine valve here

https://www.autovaux.co.uk/15263240-valve-as15263240

You will have to take the tyre off to fit

I would suggest you invest in these dust caps as I have them and they are plastic and also cover the valve completely which offers better protection against corrosion

By way of an update......
I contacted a number of local 'tyre specialist' companies. Most said that they would not be able to say whether they could replace the valve stem on a like for like basis until they had removed the tyre so that they could identify the TPMS unit as originally fitted by the manufacture (Vauxhall). They said they were sure they would be able to order in any parts needed should they not have the right ones in stock. My problem with this is that I cannot afford to be without the car and once the tyre had been removed should they not have the right part the car would need to be left with the tyre company until they get the parts in to fix it. None were willing to say what they'd charge until they had investigated further but said it could be as little as £20 if they have a suitable valve / valve stem in stock. That said, all the tyre companies I contacted seemed to think that I would only need a new valve/valve stem and sealing washer rather than a complete TPMS transponder and valve/valve stem.
I also contacted our local Vauxhall dealership. Actually two VH dealerships - one being on our doorstep and the other a bit further away. The local dealership said they'd get back to me ..... I've been waiting for two days now and still haven't heard from them. The other dealership, located further, away told me that I would have to have a complete TPMS unit fitted since the unit supplied as OEM at the Vauxhall factory is one complete item rather than being a separate sender unit and valve / valve stem. They exstimated the likely repair cost would be circa £100 including parts and half an hour's labour!
So I'm a bit stuck as to what to do for the best. I don't want to get ripped off by the dealership but I'm a bit concerned that by fitting potentially non-Vauxhall parts at a tyre company I could be invalidating the 3yr manufacture's warranty that is still currently active on the car.

If you haven't a spare wheel would take it to the dealer

More expensive but they will fix it with right parts on the same day + you get 12 month guarantee on them
