Quick question. Are they compatible? I've rented an f31 335d to fill a gap between cars and have my winters from my old 335d that I can use if needed but they don't have tpms

If you dont have the valve sesnors you will basically just get an error and a yellow light on dash saying you have a fault on the system. If you can live with the yellow dash light than its fine.

When you refit the TPMS wheels just do a tyre pressure reset and the system once you go for a drive come back on line

You will get a warning and an annoying bong unless you either fit TPMS valves or code the car so that it uses the ABS sensors to measure rotational speed to detect deflation.

Ta. The light I could live with. Not the bong!

It only bongs once on start up... No big deal

How would you know whether a car has TPMS or not?

It's not something I've ever seen on an options list. Do all F3x 3/4-series come with it?

[xenon]

From mid 2014 they do. You can tell from the outside by the tyre valves having metal stems and from the inside individual tyre pressures on the iDrive.

Ok, thanks

You could always code the car to the older ABS sensor settings and then back.
This will get rid of the light and bongs

I've just been through this and was initially going to live with the light (only one bong on start-up) over the winter months, until I was told that some form of TPMS, either direct pressure sensing or ABS sensor based, is mandatory on all post 2014 cars.
Obviously there are insurance implications so I then met up with a local coding guru who coded my 2016 car from direct pressure sensing to ABS detected but I knew that I'd have to reverse the procedure when refitting my summer wheel tyre set so I ended up fitting sensors to my winter wheels and reverted the coding accordingly.
Got a set of genuine BMW/Huf sensors on eBay for £125 (dealer wanted £320!) and everything's fine.

Were they these?

Need to buy some for my winters going on next week.

Who says TPMS is mandatory, and what are the insurance implications? There are plenty of cars that have neither TPMS nor RFT's. All TPMS tells you is you have low pressure in your tyre or tyres and should check pressures. It's hardly going to prevent something like a blowout at speed, so I'm struggling to see what the insurable risk constitutes.

However did we exist before TPMS.....?

Yes, they're the ones.

It's not me who makes the rules.
I was informed that TPMS has been a requirement on all cars manufactured since 2014 and that was a major deciding factor for me personally.
Many thanks for your clarification regarding blow-out prevention, I was under the impression that they automatically reinflated the tyre in an emergency - must have been misinformed...

[Blacktemplar]

TPMS just warns you when tyre pressure drops below a preset value, to let you know a tyre may be punctured. There's no reinflation, but the stiffness of the sidewalls makes sure the tyre doesn't disintegrate if driven flat for a limited distance.

Did you really take me seriously...?
Be assured that my previous reply was nothing less than 100% tongue-in-cheek.

Meant to say that if you do get them, make sure that your tyre shop is conversant with the fitting procedure - thet're not all the same.
The installation torque (4Nm) is quite low and it must be done with a torque wrench. After the initial tightening the collar breaks through the friction lock and I was surprised by how much further it turned as the seal flattened out, before the final torque was established.

Cheers for the advice. Ordered them yesterday.

Snap. Though there are some tragically dense people out there....

My daughter's got a new 118d on order which will come with the latest TPMS valves on it, obviously! We know her current winter wheels and tyres will fit the new car but they are steel wheels with plastic covers and have the ordinary old type tyre valves fitted. So was interested to read what has been said on this thread regarding the warning light on all the time on the dashboard etc.
Just made some enquiries with the local dealer and to put the radio valves on to the winters on her car will cost over £250 !!!
So following some of you other guys I've been raking around on e-bay but can only find ones with the part number ending in 539, apparently on the steel wheels the part number is different ending in 209 or something like that, anyway they are a slightly different valve for steel wheels.....can anybody confirm/clarify/help please??

[Jon D]

If the spare winter tyres are the same size as the new car it might be more cost effective to seasonally rotate the tyres on the new rims.
Some dealers offer a 'hotel' service to store the tyres you're not using.
