I recently had a flat tyre and the TMPS flagged up and loss of pressure.  After having the tyre replaced, and all tyre pressures set correctly, I stored the tyre pressures.  Every thing was Ok for a few miles but then the TPMS flagged a loss of tyre pressure again even though all tyres were inflated correctly.  When I switch on the ignition, the TMPS warning light flashes for a minute then stays on.  I've checked all four tyre pressures and went through the process of "storing the pressure" in the settings but I then get the waring again after a few miles (I've done this three times now).  It appears that I now have what the manual calls a TPMS system fault - the manual says:

 

- If the TMPS warning light flashes for approximately 1 minute and remains lit – there may be a fault in the tyre pressure monitoring system.
- Stop the vehicle, turn the ignition off and start the engine again.

- If the warning light flashes after starting the engine again, there is a system error.
- You can drive on, exercising appropriate caution. Seek assistance from a specialist garage immediately (in other words, spend loads of dosh!)

 

It would be much appreciated if anybody knows if there's a simple fix for this (eg, is there "Hard reset" for the system).  I can't imaging there's a hardware fault since this only occurred after a real flat tyre and as far as I'm aware, the system does not use individual tyre pressure sensors but uses ABS wheel rotation info.  If there was a sensor fault would it not flag an ABS error? 

 

 

Probably you just need to clear the fault code. I say “just”, but of course you need a code reader to do that. When I had a puncture, I fitted the space saver spare and within a few miles I got “TPMS fault” warning, ACC stopped working etc. Even after putting the normal repaired tyre on and trying to reset the pressures, the fault persisted, ACC wouldn’t work etc. Fortunately I have VCDS and as soon as I cleared the fault, everything was back to normal.

I have this now and again after changing tyre pressures (when setting up for towing/resetting after). Resetting the TPMS a couple more times and toggling the ignition sorts it.

 

Nothing came up in the last service and no idea what the cause is and doesn't seem to have a detrimental affect on anything (apart from the bing noise).

R u pressing the tyre "set" button until it boings?

 

The indirect TPMS uses the ABS sensors to determine the wheel's rotational speed.

 

U don't need VCDS or ObdEleven11 to clear any TPMS warnings, unless u have direct TPMS.

I'd start by reading the existing tpms posts on here if you hadn't seen them already, they were helpful to me when the error popped up on my way back from collecting my (new to me) car today..!

Most people will only have seen the general tyre pressure warning (which the button will reset). The OP and I are referring to a second warning which the manual suggests means imminent firey death.. (note the 'error' in front of the message)

Ah, my apologies.  

This is not the usual TPMS Warning message.

 

Ignore me......

Yeah, this error also makes all 4 tyres go orange 

Thanks all for your replies and apologies for not posting sooner - I've been trying various things but the fault it still there.   It's the fault that unclerichy showed in his post above ("Error" on the display and all four types shown as orange).

 

Given the lockdown, I'm doing naff all miles at the moment.  I though that that may be the reason (only short trips to the supermarket) and that the system was not able to get a good setting when the tyre pressures where stored.  I therefore took a jaunt along dual carriageway for a few miles and then pulled into a layby and stored the tyre pressures.  Lasted only about 5 miles before error warning flagged up again.  I've even tried storing the tire pressure whilst travelling on a died straight road at a constant 50mph.

 

I have had one other thought - I'm wondering if the extreme cold has affected the system (although I don't know where the ABS sensors are and whether they would be affected by the extreme cold).  Now that the weather's a balmy 10 degrees I will go for another spin in the next couple of days to see if the fault clears.

 

I still would like to know what could be happening within the electronics/firmware for it to flag up an error - if it is linked to the ABS system then does that mean that the ABS will not be functioning correctly?

An update - and a further question.  Now that the weather's warmed up, the fault appears to have gone away.  Can someone explain where the ABS sensors are fitted and what they consist of?  Has anybody else had issues with the extremely low temperatures we recently had?

false alarms come also without extreme weather condition

i have several times a year

 

solution is install Direct TPMS, no need to guess then, now i have online info -

Old thread.

But let me solve your issue.

You have replaced old tyre with new one. There is difference in circumference, so system thinks other tires are deflated.

How old is your tire on other side of axle, what is threat depth and depth on the new one?

I get this warning due to same reason. 

Old one is 7.2mm, new one 8.6mm, but I hope it will decrease fast, the first protective layer at least.

You can fit different size tyres or have different pressures / circumference and set the TPMS and have that logged and get no warnings.

As you might do when you fit a spare wheel and reset the TPMS until changed and reset. 

This kind of fault is common an a different brand's forum. I don't know a lot about direct TPMS, but I have had 4 cars with indirect. In my experience you need quite a significant loss of pressure for any warning to appear, usually at least 6psi. This will give a significant difference in rolling radius. Tyres with trvial differences in diameter will not cause a warning, and the system is only any good for detecting slow punctures. It will not detect a rapid deflation or a flat tyre after the car has been standing overnight. It is a cheap system to borrow from a post about Autohold, only requiring a few lines of code. None of the systems I have experience of actually tell you which tyre is deflating, although the system ought to be able to detect which wheel is revolving faster and should be able to pinpoint the issue.

The systems were introduced for muppets that did not notice punctures on 'run flat tyres'.

 

Pretty hopeless with slow punctures bit perfect for a loss of pressure / circumference is a deaf / blind person does not notice. 

 

People understanding what things do and setting and resetting is a bit of a  neccessity.

Pity that tyre fitters and Mechanics / technicians / fitters might not even know what is fitted to what or how to reset.

wrong, when installed spare wheel then reset doesn't help,

warning disappears just for short time.

also Cruise Control can't be activated,

as result i installed full diameter tire on stock 16" spare disc

Right.

because i drive cars, used to fit tyres.  Also not always trying to get people to buy after market systems. 

 

What does happen is that some models will after awhile show a 'warning'.     But then emergency spares are not for running 'long time mister'.  

 

CC / ACC etc should be disabled when an odd one out is on an axle because some people have not the common sense they were born with.

9You need some more distance in order to get warning.

I was driving with spare for few days, got error.

It was inflated to 3.5 bar, max and recvomended is 4.2.

At 4th day I even got esp intervention, braking the car on straight will driving 60km/h.

Diameter difference 3.6cm, radius 11.5cm difference.

Maybe on direct TPMS it is possible to have different pressures, but on the simple one probably not.

Msybe between axles, but on the same one, it is hard to beleive.

My new tire is now 1.5cm in diameter bigger, error come and go, but esp does not intervene.

@BingodaltonAs hard to believe it is totally possible.  

But if it is not possible for you with your car then that is that.    Not simply clever trucking about in a car with Haldex and an odd sized wheel / tyre.  

Not all cars have Haldex.  

It is original spare wheel, I suppose they know what they are doing.

It is on the front axle, it is open diff.

Still back one works differently.

if developers can disable, then they can code also speed limit

even printed value on spare disc would be better than nothing

 

for me, ~80 kms on nightly, empty and straight highway were enough

to decide replace stock 205/55r16 by 205/65r16 tire on the spare wheel

 

I wasn’t expecting this thread to be revived but it’s a bit of a coincidence since I had a repeat of the error warning a few weeks ago.

 

The error message I got was not “Loss of pressure detected” as show in MatiniB’s post on 22 Feb 2021 but the message “Error: Tyre Pressure Loss Indicator” as shown in unclerichy’s post in 11 Feb 2021 for which the manual says:

- If the TMPS warning light flashes for approximately 1 minute and remains lit – there may be a fault in the tyre pressure monitoring system.
- Stop the vehicle, turn the ignition off and start the engine again.
- If the warning light flashes after starting the engine again, there is a system error.

 

The reason I believe it may be a sensor/electronic issues is that, when the fault reoccurred a couple of weeks ago, I had parked the car up overnight (the error was not being shown when I parked) but the error flagged up the following day after a sub-zero cold night (and, on checking, the the tyre pressures they were all the same).

 

After storing the tyre pressure a couple of times the error has gone away so I’m a happy bunny now but I am confused as to why it happened.  I can’t see it being a sensor fault since I’d expect to see an ABS error.  I can only assume that it’s a software problem and perhaps the stored settings got corrupted somehow.

There are two different TPMS so messages are different.
First one is direct one and you can see which tire is deflated, second message is related to indirect (ABS) TPMS, so it just brings error that something is wrong.
If you have problem with ABS sensor, it would be shown as error and you would have a problem with stability control.

You said you have replaced the tire. So you have a new one and 3 used ones? 

On the other side, maybe you really have problem with the pressure this time. Have you checked it on all 4?

Not the case actually.

Yes there r two versions of TPMS, but both should tell u which particular tyre is the culprit.

 

Prior to retrofitting direct TPMS on mine, the indirect TPMS (using ABS wheel sensors) would still alert me to the specific tyre that has a tyre pressure loss.

 

Front-left tyre highlighted in amber in the Tyre Pressure Loss Indicator screen.

 

 

With the direct TPMS (using internal tyre pressure sensors) now, in addition to alerting me to the specific tyre, it will also display the actual tyre pressures, so I can see "how bad" it is.

never have seen which exact tire,

maybe MY17 got upgraded iTPMS version than my MY16
