Title: vauxhall mokka tyre pressure fault
Post by: raywilb on 29 July 2023, 17:45:45
a mokka on a 16plate is telling me a tyre needs air, but it doesn,t . is there a sensor on the wheel that may be faulty, the tyres are recent all round
& in good nick.

Yep, there's definitely a sensor  ::)

Nah, there's a little man, sorry, non gender person, running around with a tyre pressure gauge.

I assume that you’ve done the reset procedure.

…………
the tyres are recent all round
……

If you’ve carried out the reset procedure, maybe one of the TPMS sensors got damaged during the tyre change. Is it always the same wheel that shows under inflation.  :-\

Not sure on the Mokka.

Some systems have a sensor inside the tyre. Other systems use the ABS to detect the speed of rotation - if its ones of these, ensure the tyres are identical sizes.

It's the same as the astra, I think, sensor connected to the tyre valve.

same tyre. reset procedure carried out does a new sensor need programming in once fitted ?

So pleased I've none of these " helpful aids" on my cars, simply check them once a week with my antique Dunlop pressure gauge.

is it telling you that a specific tyre is 'flat'? Or is it telling you that you that one of your tyres is 'flat'?

  the same corner needs air, tho as I said it doesnt , anyway its a job that requires the bead popping so its booked in to a tyre shop

but is the car telling you that you have a particular tyre that's flat ie direct system that has a pressure/temp sensor in each tyre & tells yo the pressure of individual tyres?
OR is it telling you that you need to go looking & one 1 of the 4 tyres is flat ie indirect that uses the ABS?

The system in my old Jag would always show an error message when the weather was  very hot or very cold.

A lot of these 'driver aids' are just  to pander to drivers who are to idle to check their car once a week. I also know when it's raining ,because i see these funny wet spots all over the windscreen.  :D

Before I changed the battery, mine used to come on every time it went sideways.  With new battery, I only see it if the car has been left standing for a couple of weeks.

You really should go for black and round type tyres for a bit more excitement and the added driving experience!  ;D

Who honestly checks their cars' tyre pressures weekly ... or even at all, unless they think a tyre is soft
I like the auto wipers on my ML .... but I manage quite well with our other cars that don't have it  :y

the only time I've had a problem with the indirect system on my car was when I had a wheel that wasn't balanced very well (or it threw a weight  :-\) It was forever telling me to check tyre pressures when there was next to nothing between them & the system had been reset. Had the wheels/tyres rebalanced & that was it .... sorted! :y

No idea what the relationship between ABS sensors & unbalanced wheels could be  ??? ???

Don't get me started on lane departure avoidance. It's dangerous.

Also front collision warning which likes to apply the brakes every time a sharp bend is taken at more than 10 MPH. I can't switch this off so I have set it to spring into action as late as possible.

It's all nanny state crap.

My car would give  a low pressure warning that could be made to go away if the car was driven for a mile or two. Presumably because the tyres became warmer.

I have to remember to turn them off when I park at work. Otherwise, there's so much crap on the screen that they come on as soon as the ignition goes on, smearing detritus everywhere ;D

and do you regularly have to top your tyre pressures up? My tyre pressures rarely alter ....

Only very occasionally, one of the Subaru tyres has recently started losing about 3PSI over about a week but is due for a set of new tyres shortly, I won't change my habits of a lifetime though .

Pretty sure the indirect system is no longer allowed as it was shown to not give the intended warnings (I am told it never met the original regs).

My fronts used to lose about 3psi over a couple of weeks, so had the rims cleaned when i had new Nexens fitted. Solved the problem, so had the rears done when the became due. £25 a corner as i seem to remember.

The only warning I've had in the Range Rover recently is low coolant level, however it's not low at all apparently it's a common fault with the float becoming inoperative after a few years so a  complete new coolant container is being fitted when it has its service next week.

We in general on here may not like TPMS but, the general public has turned into people who have zero idea about cars at all. Hence why TPMS is now a requirement to be fitted to all cars and why spare wheels are disappearing.

There were many serious accidents where cars with poorly inflated tyres were the cause, if you now splash it across the dash when this happens generally, (and there will always be a minority who don't) the car is stopped and checked.  :y

Sensor battery life is about 7-10 years typically (depends on use as they only wake up when the wheel moves) and the sensors are not stupid money like they used to be (and only require a generic tool to program them.....as this is also part of the requirements)
