Tyre pressure problem

Probably a slow leak from something embedded in the tread. The fleabay part is not the complete TPMS unit and you won't need one unless a troglodyte damages it while dismounting your tire. If it's a run-flat then be sure the shop has experience as the tire bead is really hard to shift. Putting a patch on the inside is the safest repair but the tire's maximum speed rating is reduced - not a problem in most countries!

Thanks for the reply,


if its not raining tomorrow, will jack up rear and see if I can see anything on the tyre,
im not running runflats, and have a choice of 2 tyre places that are ok, so will call them in morning to see if they can handle a wheel with TPMS

If you need to replace your TPMS please do not do it with an Ebay certified part. You may get lucky with finding one with minimal issue, but you also run a higher risk of finding a TPMS that is garbage, which would essentially cost you a third trip to the wheel shop.


Spend the money on a genuine part, especially with the money you spent on the car. If you can afford a brand new F56S, you should be able to afford an OEM replacement part

I found new OEM TPMS on Amazon for $56 each.

I get it completely.


The parts on anything can fail at any point, hence why TVs can have dead pixel upon opening, and nice clothing can have a stitch come loose. It happens and they are an anomaly.


I only say to go OEM as possible due to the fact that your tires play the most integral part in the safety of your vehicle (kind of like replacing an airbag, you only want OEM products to ensure you do not sustain serious injury or possibly death). It's best to keep the only things that connect your car to the road as genuine as possible. It also wouldn't hurt to keep a mechanical old school pressure gauge in the glove box of your car. That way you know if it is just a TPMS sensor acting up or if you have an actual leak.

actually have a nice shiny chrome one somewhere that I used to use on my triple so will dig it out,


and totally agree with you, I have always tried to stick to authorised! parts on my minis, even down to replacing the horrible plasticky looking surrounds in the interior of the R53's and R56's with nice chrome ones, as a posed to getting those stick on ones!! while not a safety issue they definitely helped with my eyes


thanks again for all the advice guys, once I know if the tyre is def deflating I will take it to the guys at bathwick I think, and see if they can fix it without damaging the tpms module/valve, but will call them 1st, as they may well be able to get the parts at cost should anything need replacing, they are pretty good guys there


P.S
I should add I moved to a new build last august, and there is still building work going on, so I guess if I have a puncture of sorts it might be as a result of debris lying around etc,

Sounds like a puncture; we had one recently on the family Dacia Duster; fantastic Continental x contact tyres-very few miles on and there was a piece of wire stuck int eh side wall so the tyre was a bin job; the tpms just stayed, and they put the (hooray-full size spare on the car) and replaced the spare with a cheapy they had in stock-just hope that's it for punctures. Just no idea where we got that from as we dont frequent building sites etc

At least its in the middle so 'should' be repairable. Every time I have had puncture, its been on the shoulder of the tyre making it scrap

yeah def hope its repairable from there, my main worry now is it gets fixed with my alloy unscathed!


gonna call out a mobile tyre guy, its a local tyre company, but at least it will be done right before my eyes, and is only a couple of quid dearer than driving it in to get done, plus the less miles I do on it till its fixed the better it will be for the tyre,

Make sure you unscrew that instead of just pulling it out. It will do less damage to the wires in the ply and belts.

thanks for the reply and advice


the mobile repairers were booked up , so I took it in to a tyre place in the end


£20 later and was all sorted, so hopefully many more miles happy motoring on those tyres >
