Title: TPMS batteries
Post by: STEMO on 28 February 2020, 17:38:53
Anyone got any idea how long these usually last?

TPMS are a pain in the arse.

Hate them. Just a shit load of random faults that don't actually exist.

I have tried to switch mine off but apparently TPMS is part of the MOT. :-\

Thanks for the constructive help  :y


TPMS checks were added to the MOT test checklist in January 2015 and it is now an instant MOT fail if the TPMS dashboard light is displayed for a fault or a problem with the TPMS valves is discovered. Many motorists don’t realise this which has led to thousands of new MOT failures that could have been easily avoided.

That information is from Kwik fit, btw, so must be correct  ::)

Mrs builder's TPMS (aftermarket kit) have lasted 18 months or so
but they are easy to change the batteries in anyway
the OEM ones i imagine have to be removed as a valve from inside , break the bead  :-\

4 years is the best I can get from the astra k forum, but they're definitely not as technical on there as here. Wife's car is around 39 months old, so we'll see. TBH, it's not something I'd given much thought to, but I followed a link and came across an article on TPMS in general, nothing Vx specific.

sensors are about £15 = 20 a corner looking on ebay
then you will need a tyre machine, bead breaker ,wheel balance machine etc £10,000 should cover it
then need them reprogrammed /synced

ask spiderman garage how much they charge
ask price first and take Vaseline this time   :y

This one would be a job for Vauxhall. I wonder how many people will be caught unawares, as I would but for a blunder onto the web page.

I still visually inspect Mrs Builder's tyres for condition etc even with TPMS  but think it is a good system
I see a lot of cars driving round with near flat tyres
but even if you have TPMS ,you need to act when the light comes on , i suspect many don't  ;D
Mts Builder's TPMS makes an annoying noise that can't be ignored .....
"Dave, my TPMS alarm is going off "  ;D :D

My TPMS is the more simple ABS based version .... no batteries required  ;)

Wifey's TPMS alarm hasn't never gone off. It's only a button press to show you the pressure in all four tyres, and I make sure they're correct.

The Audi has TPMS based on wheel rotation speed, but as I purchased a full car + caravan set when I had the omega I still use the pressure based system from tyrepal ... as it does car and caravan ....  and it has proved to be far more accurate than the audi system  :) batteries in the "senders" last about 2 years and take less then 5 minutes to change   :)

The 'rolling radius' or ABS system allows for tyre wear, so has quite a generous margin. It's primary purpose is to warn of a sudden or significant change in pressure against an datum of all four wheels.

It costs manufacturers nothing to 'fit' to the existing ABS ecu... Not that this stops them from charging a £500+ option tax on it ::)

I think in the old days people would put air in their tyres when they needed to.

However, these days nanny knows best and tells you of problems that don't actually exist.

I'm guessing that wheels need rebalancing after fitment?

Nope, tyrepal system works like a valve cap. Major reason for purchase was to know what was happening with the tin tent after an incident on the M5 which could have been extremely serious, but luckily for us was just an annoyance... never been so grateful for a traffic jam in my life !! OK needed a full recovery of both car and 'van by greenflag which seemed to take forever .. but better to happen stationary than at the 60 mph I was doing 5 minutes previous!!  :)

 Correct me lud :y

Bit like auto-wipers, and auto headlights, how did we survive driving death traps like marina TC, or mini 850.

But surely each module is far heavier than a dust cap? Hence the rebalance query.

I'd guess a dust cap is around 2g, and any transponder with a small battery must be at least 10g.

Following her blowout on the motorway last year, I am looking for potential options, so have a keen interest in your experiences :)

Never had a problem with balance after fitting them ... and have been on 2 sets of tyres on the Audi and must have been 5 sets on the omega

I have the TC215/B with 6 sensors ... but 4 sensor sets are available ...    https://www.tyrepal.co.uk/product-category/product/

User manual here :  https://www.tyrepal.co.uk/wp-content/uploads/2017/06/TC215B-user-manual-contents-20160222.pdf

extract from that ... "3.1 Wheel balancing
The weight of the sensors is within the tolerance achieved for wheel balancing, so there is
usually no need for the wheels to be rebalanced after installing the system. If vibration is
felt when driving at speed after fitting the system, the wheels must be rebalanced."


HTH  ... :)

Cheers for the info.  If you ever get 10 mins, can you weigh one?  I know I can feel if its 5g out (TBE runs on 18/8, making it more suseptical)

that 4 tyre set is what Mrs Builders astra estate has fitted  :)
hers was branded DUNLOP (the tyre company)

same sets on ebay ,non branded, for sub £20 delivered

sometimes have to plug the display in to charge (via USB lead from the stereo) as the unit doesn't get much sun where she parks at work
but the batteries are easy to change in the valve cap sensors  :)
internal battery is IIRC a small 3.7v  lithium ion that could be swapped for bigger.
the display unit screen goes to sleep unless movement is detected ,to save battery life
not sure how accurate the tyre temperature readings are , but the PSI or BAR (you can choose either) is pretty accurate

the only thing i would say is the sensor valve caps are big ,so......
 not a great item for someone who stuffs their N/S tyre wall into the kerb every time they park  :-X

as it is a completely aftermarket ,independent system from the car , not an MOT item
though if its bleeping, chances are, they tyres need air ,which is an MOT item  ;D :D

Just took one off and weighed it complete on SWTSMBO digital kitchen scales.... no idea how accurate they are but are the best I can do ....   7g ... old "normal" dust cap in the garage ... 2g ... so 5g extra

HTH  :)

It does, thanks. So that would mean a rebalance for her car.

That would of course be up to you, but I've never felt any vibrations at all in either the Omega or the Audi at any speed (even on a private test track .. !! ).....  if you went for them I would suggest trying without a rebalance first ......    :)
