Hey guys
Had my F56s for a month or so now, really enjoying it, no dramas!
then this morning leaving work, the TPMS system reports o/s/r tyre is low
both front tyres report 38psi approx. both back seem to be 35psi
but the o/s/r is reporting its at 26psi,


anyway I stopped the car, check it, all seem alright to me, so took a bimble to Tesco and sure enough their inflator machine states it was at 26 psi,


so filled it up to 35psi, then this evening, its back down to 26 again!


true test will be in the morning, im guessing I may have a slow puncture/leak!


not sure why its staying at 26 psi thou !


anyone come across similar ?


also if I do need the tyre off, im guessing will need a new TPMS valve ?


seen this on fleabay any thoughts

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

yeah I do appreciate what you are saying, will def try the dealer route 1st,


But be careful what you say, I have not purchased an Aston Martin DB9!


I sunk every penny in the deposit for my car which I pay monthly for on the basis it made more sense owning a car that realistically should not cost me any extra than usual running costs bearing in mind my previous used car had cost me an extra £2500 in the last year in faults n fixes
,
obviously I have allowances and things happen and all that, but my car has barely reached 1300 miles, and now I have a tyre/wheel/tpms to sort out,


just not funny really, without looking I cant be sure what tyres im running, but pretty sure they are Michelin pilots!


all my other minis have had on them are standard continental sport 3/5's on them
and not a single flat/puncture,,act of god!! the lord of Conti is abviously not happy with me lol

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,

 

[MaDMaX**]

Ha
Found the culprit
Now to see if I can get it repaired

 

[MaDMaX**]

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,

 

[MaDMaX**]

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 >
