I have ordered a new wheel for my Renault Megane IV (energy business, 2018) because one of the wheels was a bit deformed and a vulcanizer advised me to change it. The original wheel has tyre pressure sensor (TPMS). My mechanic says that the old TPMS (which works fine) cannot be used on new wheel. The new wheel is the same as the old one (both new and old parts are original)

This is the type of wheel :

190738



Can anyone confirm is this correct? These tyre pressure sensors cost 50% of the price of the wheel. This seems like a design flaw because you have to buy new sensors every time you buy new wheel. Also, what would happen if I decided to install some third party alloy rims that don't have sensors? Would there be any annoying dashboard warnings?

I'm not a specialist in this field, but I'm almost sure that you can just unscrew the valve stem and remove that sensor and fit in another wheel 馃 it's the only thing holding it in place to your damaged wheel.

The sensor is literally for just monitoring tyre pressure. I don't see how that would need to be fitted and kept within the same wheel forever.

Agreed ^^^^^^^^^^^^^^^^^

Maybe your mechanic means that you shouldn't move the tyre valve to a new wheel, which is reasonable advice.

Yeah that would be wise I would imagine. If that's what your mechanic meant. Then that's good advice.
Ok, thanks for clarification everyone! What would happen if I installed wheels without sensors? Would there be any dashboard warnings?

You'll most likely have a low pressure warning with the stop light illuminated. I know that was the case when I had an aftermarket sensor fitted. Suffice to say, OEM or go home when buying sensors.
