I've moved your post to the relevant section.
Did you check your tyre pressure manually?
If that was OK, then you probably need a new tpms sensor fitted. To do so the tyre has to come off, but most decent tyre fitting places should be able to do it for you.

 

Hi my sensor isn't working correctly, states this below the tyres are holding pressure so think it's a replacement sensor around £60 from vauxhall is it just a matter of getting a tyre guy to replace it and that's it or will it need programed

 

A decent independent tyre fitting garage could replace the tpms sensor for you, you could even buy one first yourself and give it to them to fit it. Then just needs programming in using the relearn tool. A replacement sensor is a lot cheaper than £60 if you buy one off eBay using @Valer part number supplied on his earlier post.

 

Yeah I'm sure they would I'd rather get a genuine one, I did ask the tyre guy earlier he says get a genuine one don't mess about with eBay ones there shit loll,
Guy in vauxhall parts gave me this number on there parts list for my reg
YQ00956280

I had one changed fairly recently on my previous 2018 Astra K, under extended warranty. Although if one goes, there's a fair chance the rest would be ready for changing. As the batteries inside them don't last forever. I'd certainly consider changing the other 3, when you change the tyres, next, cuts down on cost.
As we are seeing Stellantis parts seem to becoming expensive.

 

They are gradually changing the old GM part numbers to their own versions,i have updated the TPMS thread

 

I'll get the 4 then you wouldn't have a link to the ones I should be going for,
On a side note been driving for around 30mons and it's went off must be a fault in it definitely

I think @Valer had left a link to the type you need with the part numbers. When I replaced the 4, it was on a previous 2016 Astra K, I've gone through another two Astra's since & now own a Skoda, so I can't remember the sellers I bought them off. I took a while buying them, as I was in no rush at the time, they were all original off ebay. Think the most I paid was around £20 each, then around £10-£15 each for fitting.
It might be best for you to replace one first, just to make sure it was the tpms sensor that was the issue, which I think it probably is. Then buy the other 3 sensors, ready for when you want to have them fitted. Well it's what I'd probably do, anyway.
The last one I had fitted was through vauxhall (extended warranty), I was given no paperwork.

 

I was thinking exactly that get the one see how it goes and then get the remaining 3 I have saw them on eBay as low as £9 same numbers i just wasn't sure if I should order them, I'm going to get everything orderd today for fitting this week,

 

I'd recommend something like these,and leave any aftermarket ones alone

Pardon our interruption...

Pardon our interruption...

 

Thanks @Valer I had one of them on my watch list I'll get them ordered once the others go

 

Well a little bit of good news I went to my tyre guy he was going to call his vendor to see if I could get any today, couldn't get one untill monday so he stripped the sensor out inspected it and couldn't see any fault cleaned it and put it back on light continued, as I was driving by Arnold Clark I popped in and told them about the issue and they fitted a new one for free, so all done cheers guys for all the advice and help I really do appreciate it

 

Good result

 

Cheers guys

 

Ok so driving last night 60mile round trip and on the way I get a message inflate tyre and a flashing light in that the same wheel that the psi is at 26 went off immediately, and showed 38psi, done it one more, but didn't don't on the way back, wondering if it's an issue or relearning

Secondly I bought a new sensor just incase YQOO956280 39243434 they look different from the one that came out my tyre, bottom is my old one and top is the replacement different number on the sensor

 

The original sensors fitted were13506028 now superseded to 39186445 then finally to YQOO956280,
i'm not surprised they look different

 

Really confusing , guess thats on purpose

 

They have always changed part numbers on parts sometimes due to spec changes,change of supplier etc
now there's an extra layer of confusion as they up date to Stellantis part numbers,it's almost impossible to keep up with tbh

 

I spoke to the guy in Vauxhall auto parts and he said the same, they have over 12 different numbers for the same part on numerous parts and can be in different colours too depending, but he couldn't verify the older numbers only new ones on there computer

 

Do you just fit these on wheel and they pair up or do you need them to programmed at a dealer??

 

They don't automatically pair up but need programming with a cheap diy tool el50448
full details are in the link to the tpms sticky i posted earlier in this thread
here it is again
