« on: 12 September 2025, 08:15:35 »Both Astra's are now 8 years old.

Mine has done 23k.
Should I get the cam belts changed?
I recall from one of your other posts, that these engines are the 1.4 variant, in both of your Astras?
If so, I am 99.9999% sure they won't have cambelts, but rather, a timing chain setup. Which, at those mileages, won't need disturbing yet.
Best bet if that's the case, is just to make sure the oil and all filters are regularly changed (more often than the recommended intervals, in my humble opinion)
Thanks James.

Fortunately I bought the tool from Amazon and have got a full refund.

So when you execute the TPMS learn function via the menu, is it actually entering the learn.
On some Vx's, when in learn mode it flashes the indicator adjacent to the wheel which it is looking to learn, you then use the tool you have to provoke the appropriate sensor into transmitting its ID code (by holding it to the tyre wall near the sensor).
It should then do a short pip on the horn before flashing the next indicator adjacent to the next sensor to learn, you repeat until the are all learnt.
The tool you have does nothing more than make the sensor talk to the system.
Its worth checking you have no cheap gadgets which work, or could interfere, with the TPMS systems installed and working on the car.
I did speak to our TPMS team, our system works by monitoring the wheel rpm via the ABS sensors and correlating it with that from the sensors. The wheel speed changes for each wheel when cornering, the first drive cycle does the learn, the second a check and then it is stored and activated mid drive cycle.
I have done pretty well what you have described.
Menu in learn mode.
Tool bleeped on first tyre.
Would not bleep on any of the other tyres.
The display was reading zero for every tyre.
The display also read 'Service tyre pressure monitoring system '
Nothing changed after a good drive.

Bargin!
Persuing other options.

So, I bought one.
Totally F***** up the system.
Tyre pressures now reading zero - and display say service tyre pressure system with warning light on dash!
Took it for a run and it's made no difference.

Up the shute again.
100 mile round trip front nearside showing 27 psi, rear nearside showing 44 psi.
No amount of resetting or playing with the menu's make any difference.
Looks like an expensive trip to the dealers

My tyre pressure monitor looks like this and has served me perfectly well for almost 50 years , well not the same one but the same type.

This modern nonsense is over complication for the sake of it.
If you cba to check tyre pressures once a week you shouldnt be allowed to drive.
Agree entirely , I've had my Dunlop pressure gauge for as long as I can remember always check mine every week along with oil water & screenwash.
I go round and kick each tyre on a daily basis.

The good news is my car insurance has gone down by £50 this year.
Still astronomical because of my age.

Astra K gives a reading on all 4 tyres,
It has a reset button to enable it to recalculate the sensors.
What they don't tell you it works with a separate menu that has to be set according to the load in the car.

« on: 07 August 2025, 17:19:26 »Problem solved!Yeah, this happened to me when I was 'fiddling' with the settings on my Astra.
There are 3 tyre settings :-
Light
Eco
Max
For some reason it was set to Max where I have always set it to Light.
Don't know how it happened, but setting it to Light has cured the problem.
Ha ha.

My front nearside tyre pressure sensor has developed a fault.
Keeps telling me the tyre pressure is about 10psi less than the other 3.
I've done a reset several times to no avail.
Is it an MOT fail as a warning light is showing constantly on the display?
Where's the best place to get it replaced?
Is it a dealer job?
