Broken Tyre Pressure Sensor Valve stem on a Peugeot, repaired in Worthing

I was called out to a customer in Worthing with a flat tyre on a Peugeot 407. The AA had come out to the lady roadside and fitted her spare wheel so she could get home. The AA couldn't find any sign of a puncture, so they told her there was possibly a leak from around the rim. She called us at Hometyre and ordered a new tyre.

When I got to the job, I took the wheel out of the boot and when to put some air in it to try to find where the leak was coming from. This immediately showed that the metal valve was split (see photo). This often happens when people fit after market metal dust caps, they corrode to the valve stem, then when they are forced off, they break the stem, for this reason I often recommend to my customers that they use only plastic dust caps.

This car has TPMS (Sensor valves), which is something

we can repair, we carry a vast range of replacement parts for all makes of sensor. I took the tyre off the rim, removed the complete sensor, then took the stem out of the sensor. Located the right part and fitted a new stem with sealing nut, then inserted the completed sensor back into the wheel rim, re fitted the original tyre, balanced the wheel and put it back on the car. I was then able to check the TPMS system to make sure it was all working correctly.

The customer was happy as the sensor parts were cheaper than buying a new tyre.

If you have sensor valves fitted to your wheels and the car is newer than Nov 2014, then they must work to pass an MOT.
