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.

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?

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?

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?
