Tyre Pressure Sensor Warning Light XE 2015

Recommended Posts

Hey guys,

This morning I was driving into work when the tyre pressure sensor warning light came on with the message "check all tyre pressures" appearing in the centre dash reading. I originally thought I might have hit something (which I didn't)  and the tyre lost pressure or I knocked the sensor out of position or even a puncture but looked around outside the car and nothing seemed wrong. 

 

Not sure if anyone can help me or has experienced something similar but its a XE 2015 model and the tyres have about 1,000 miles on them as does the car itself.

 

Thanks,

 

Ward

I have seen these light up due to clipping a slippy surface, or losing traction on one wheel, or spinning up one wheel due to an enthusiastic departure.  That type of stuff anyway.  The sensor must see one wheel rotating differently to the other 3 and sends it as a fault due to pressure/circumference reduction. I don't know if that's exactly the technological description, but that sort of idea of fooling technology into thinking it's got an issue.

Whilst this is true for the type of TPMS system that uses the wheel speed sensors, The XE doesn't have this sort of system. It has actual pressure reading valves in each tyre.

The check all tyres message is very common this time of year as temperatures drop and so the pressure in all 4 tyres drops accordingly. You will probably find they are all down 2-4 PSI from the ideal, top them up!

 

Edit: Just seen this was an ancient post, sorry.

Ah - that's where knowing your tech comes in.  My quote was from 'Vauxhall' tech, where Jag has proper tech 😉

Same actually happened to me a short while later - topped up - all fixed.

Didn't matter you were a late contribution - I learnt something - every day's a school day
