Hi 2015 Jeep Renegade 4x4 2ltr, my tpms says its unavailable I had National tyres take a look and found the sensor had come off the valve and loose no reading from it so assume its broken. He unfortunately could not replace the Sensor as he did not have the tech equip to read the new code and update the Ecu. I contacted Arnold Clark Jeep service and asked for a price to resolve this issue and Mot as its due soon. They are asking ÂŁ180 diagnostics before they start the repair. Do any of you know of a garage KA13 7DX who can fit a new sensor and get the display working again.

Hi yes I now have that in place sadly not until next week, I have phoned about 2 dozen garages Arnold clark the dealership want ÂŁ180.00 to do a diagnostic to find the fault I already told them about so this will be ontop of the repair cost then Mot cost so a not so cheap fix. I have a Jeep approved garage doing the work plus Mot for the same price Arnold clark want for Diagnostics. Any who it's going into the Garage Monday to be repaired fingers crossed.

According to my 2020 USB Service Manual, the TPMS sensor is removable from the valve stem. In fact, the valve stem (and core) is supposed to be replaced every time the tire is removed from the wheel.

To remove, the spring clip (item 5) is depressed with a small screwdriver, and the sensor is pulled off.

So is it possible that the clip wasn't quite latched; the sensor just came off the valve stem; and that nothing is really broken?

(Of course, if the sensor was then banging loose around inside the wheel and tire, it might be broken now... :rolleyes: )

And yes, the Service Manual does say a new sensor has to be programmed before it works. But I'd think any good tire dealer would have the tool to do that -- a common brand that does that, at least here in the U.S., is Autel:

If you're confident the sensor or valve stem is broken, then asking a repair shop (or dealer) to just replace the sensor without doing any diagnostics should work. Problem might be that they wouldn't provide any warranty if it turns out that something else is wrong...

If you buy a sensor, make sure to buy the valve stem too as they are not "standard". There was also a spare stem included in the breakdown kit iirc.)

A new sensor will need to be OBD programmed to the car.

Any good tyre place with Fiat experience will do this for you.

My Fiat independent was able to rotate my wheels and re-assign the sensors to the new corners without any issue using his Fiat/MES set up.
