Tyre Pressure Warning Light - Can't See Forest For The Trees!

[Transporter]

Ah, eBay - 433Mhz. Might be worth my while then?

Regards removing the sensors and replacing with new, I assume it's plug-and-play from an electrical point-of-view as long as they're 433MHz?

I assume I have to deflate each tyre in turn then and somehow pry the tyre back on the wheel where the valve is to get at the sensor on the inside of the wheel? Thought this would need a tyre shop - I only have have fairly basic tools...

The sensor is a part of the tyre valve. A reputable tyre shop will swap them for you. I’d probably wait till I need new tyres.

Just before I do the tyres then I'll get a set of 4 x 433MHz sensors (ITM Brand) on eBay - will cost me c. AUD180 to get sent to me from USA. Will see if the tyre fitter can install them.

Just one question, not sure why they don't sell a set of 5 to accommodate the spare? If the spare didn't originally have one fitted then I've lost track of which wheel is now the spare? Maybe one of the wheels on now doesn't have a sensor (originally designated spare wheel?) and the wheel with the sensor is in the boot? Is there any way of telling externally?

What is the current spare? If it's a matching alloy wheel then it might, if it's anything else (especially a space saver) it probably doesn't since it's only designed to get you to a repair/replacement place.

It's a matching alloy, so probably need to buy 5 sensors.

I also have the same problem of a flashing then permanent tyre pressure warning light - presumably due to a TPMS battery going flat in a valve. It's amazing the batteries have lasted since the car's build year of 2006!

I too will wait till I need new tyres to change all 5. Thanks for the eBay tip! I do have access to VCDS to disable the function but the owners manual talks about holding down the button in the centre console for more than 10 seconds to disable. Is this a permanent fix?

Your tyre pressure sensors have batteries in them. They are at the end of the useful life.
You'll need to replace the sensors, the batteries are embedded in them.
Passat has direct TPMS using sensors in the tyre stems, with the receiver integrated in the CCM behind the glovebox.

HECK! Does my Golf R build August 2018 have batteries in the sensors? No mention in my Owner manual but omission of that sort of advanced info. wouldn't surprise. Please let me know & if so it will be duly noted in my manual.

No you don't have tpms direct.
It's indirect via the wheel speed sensors being monitored by the abs.

Thx kamold. Following my nomination, look out for a knighthood on Australia Day.

I'll be waiting by the mailbox...
