Just a quick sanity check, has anyone made a successful warranty claim for a failed TPMS

TIA.

What failed, the transmitters in the wheel or the receiver in the car?

Wheel sensor, I think. Random amber warnings but pressure readings within the acceptable range.

Batteries will be running low in the TPMS sensors.

Not covered under warranty as they are a consumable, mine failed after 8 years but you can buy non OEM (same manufacturer though) sensors online for a fraction of what McLaren charge.

You just need to double check what frequency yours transmit at - UK cars are nearly all 433hz but some early car (like mine) were built with 315hz ones.

Thanks, had a sneaking suspicion they'd be life timed, hence not covered...

Be careful with non genuine sensors

I bought some for my 12C and they would randomly alternate between one not reading properly. At first I thought I had a faulty one so order a new one and fit

But it would alternate between different wheels which would not provide reading

Thorney also warn again non genuine as they have similar issues

OEM ones are ridiculously priced

Thank you.

If they are battery powered, and it's this cell that goes down so to speak, can I infer they are sealed units, impossible to replace; resined in? Or similar; has anyone tried to tear one down?

I use these sensors on a second set of wheels. No issues reading pressure or temperature when swapping between the wheels. Had to tell them they were going on a 600LT as I assume they need to program them in some way.

I think McLaren wanted £600-700 for OEM ones.

One of mine reports 5C hotter than all the others once they're warmed up.

They start the same and then the odd one out starts to diverge in temp reading.

I checked with the dealer on the warranty apparently anything up to 7 degrees difference is still in tolerance biggrin

7 degrees... that's some margin.

Yep, seems like a lot to me.

Same. Right rear is 4-5 degrees up on the left in steady state driving.

Its pretty straight forward to get the autel MX TPMS sensors and program them to be clones of the McLaren ones (or any other make for that matter) Autel TS408 is the unit you need. Very cost effective compared to the OEM sensors. Quite a good thread over in the Aston Martin area of pistonheads on this topic

Not sure why they would be any different from the 4 on my astra.

Possibly a coincidence but it's my right rear too.

I think I may have noticed the same.

I wonder if there's a heat source in the right hand side of the engine bay that warms that tyre?
