So I have an ongoing issue with my TPMS sensors / reading in my 570s and wanted to get some advice on how to get this fixed. When i bought the car i had a TPMS warning light on and had the dealership install new TPMS sensors by discount tire. The ones they bought were this particular model: BHS UV7050 TQ40 315/433 MHZ (shoptpms.com/Huf_Intellisens_UVS7050_p/uvs7050.htm) . After driving the car for a few miles i had the readings started showing in the car but they were incorrect (91psi and incorrect temp) and the TPMS error came back on the gauge cluster. I had discount tire order brand new TPMS sensors (same model) and took them to the Mclaren dealership for them to install them. The dealership installed them and forced the sensors to 'relearn' through the MDS but the TPMS error came back yet again with the same issue (wrong PSI, temp and the error in the guage cluster). Of course the dealership claims that the 570s needs OEM TPMS sensors which are about $1100 with installation, however, i have read multiple posts here saying that people have gotten aftermarket sensors to work with the 570S.

So what gives? Am i using the wrong TPMS sensors? From my understanding most 433 MHZ should work with the car. Is there something which i am missing or any setting i need to change.... Or do i just need to go with the OEM sensors and pay Mclaren $1100 to install them? Am i able to clear the TPMS error through my ODB scanner? Any help would be much appreciated. Thanks

Huf RDE048's require no programming, no settings, no anything. Put them in, they read. I don't even drive and they read in P11's. Plain and simple, they just work.

On a related note, the issue may be your car is set to look for 315 Mhz sensors, not 433 Mhz. I corrected this on a car that front read and rear didn't. Rear were set to 315 Mhz for no good reason.

Appretiate the feedback. Dumb question but where can i set the car to look for the 433 Mhz sensors? is it something i can do in the car's menu or would discount tire / tire shop be able to do that ? Thanks!

It requires MDS or possibly a similar tool to change that setting.

Definitely something to look into. I tried two different sets of RDE048s and had some problems. Initially tpms will read and take multiple drive cycles / miles for them to eventually self-program. Knock-on-wood my sensors are reading OK but have twice now errored out with TPMS Fault, but self corrected after about 10-15 min of driving.

For whatever reason the car seems to not like the new HUF sensors but was OK reading the previous RDE018s (slightly longer in design when compared). Not sure if its the revision of sensor, an issues with whatever device is reading the sensor (car-side), or some kind of interference. Multiple people on this forum and the facebook 'McLaren enthusiast' group seem to have this problem on their 570x/600LT from a quick search. Will definitely ask to have the car looked at and verify MHZ setting during the next annual.

A bit off topic but, is there an option to completely disable Parking Sensors, or have them set to OFF upon start on the MDS?

Thanks

Maybe you have an antenna going bad if it goes in and out, or a loose connection at the antenna or receivers. If more than 1 goes out at the same time I'd look at antenna.

So there definitely are antennas, not just an internal antenna inside the controller?

There are 3 components to it. In the wheel, a box in the wheel wells, and a box in the front and rear of the car.

And you think the boxes in the front and rear are antennas? Is this for all platforms?

I know they're antennas, same for all platforms.

I suspected as much, I've never seen a car with tpms without them. I suggested this as a possible source of the problem @houstonT had with his rear tires, makes even more sense if there's a front antenna and a rear antenna.

The rear antenna of P11's is mounted to the transmission undertray. It's not uncommon to not quite plug it in all the way when putting the panel back on.

His works with stock tires but not with the ones he fitted.

Gotta be the sensors used then.

Nope. The same sensor work with stock tyres.

So what you're telling me is, the same sensor is in a stock tire and another tire and it works in the stock tire and not the other tire?

Yep. There's a whole thread about it.

Obviously the tire carcas has a layer of copper, making it a faraday tire.

Works on other cars if I remember correctly.

To the OP: What tires do you have?
