2014 XF S Portfolio V6 D - Persistent 'Tyre Pressure Monitoring System Fault' Message

[Smutley13]

Hi guys,

First post from relatively new first time Jag owner, a 2014 XF S Portfolio V6 D. I have a persistent Tyre Pressure Monitoring System Fault that comes up on every start-up following some work. Note that the TPMS system had no issues before it went in for repair.

The car recently went in for a bumper and headlight replacement after I hit a muntjack doing about 30mph. I collected the car after it spent 2 months with a Jaguar authorised body repair centre (long leadtime on headlight). When I collected the car, the TPMS System Fault come on after about 100 metres of driving. I checked/corrected the tyre pressures when I got home (one slightly low due to a pre-existing leak from the valve stem).

The following morning, the TMPS system fault warning appeared again at start-up... it dissapeared about 5 miles later. That evening, after work, I drove the car to a a well respected tyre-fitter and alignment centre (the body repair centre had only corrected the front toe angle, and the car was driving horribly). They performed a full alignment, balanced both front wheels and fitted a TPMS valve seal kit to fix the slow leak. I drove a few hundred metres down the road and the TPMS system fault warning returned, and I haven't been able to get rid of it since.

I have driven approximately 600 miles since it permanently returned. I have;
> checked the tyre pressures
> let the tyres down to 20 PSI, started the car and reinflated each one to 34 PSI. The car correctly reported that all tyres were under inflated and the errors cleared once inflated.
> removed the fuse from the TPMS (F33 in boot fusebox) and drove the car to and from work (40 mile round trip). Reinstalled the fuse the next day. TPMS system fault reported throughout. Weirdly, the system correctly picked up on one of the tyre's pressures dropping to 30PSI, even though the fuse was removed.

So I'm a bit stumped really - seems like all sensors are functioning and reporting correctly, but the car is still reporting a generic TPMS system fault. The car is going back to the body repair centre tomorrow to have a new skirt fitted (missed in the original work), so will ask them if they can reset/diagnose further, but any advice on how to reset this/remove error message would be greatly appreciated.

 

Cheers,

Joe

TPMS initiators are mounted in the front bumper.  May be worth checking if they have been installed/ reinstalled correctly

You need to get the codes read

Otherwise it’s just guesswork

I also have the same problem. Just comes on and goes off randomly. As above, no low tyre pressure warnings. Had it checked and there were no faults showing for it.

The receivers for the tpms sensors are mounted, front and rear, on the lower part of the bumper.

You have to partially remove a bit of the arch liner to see them

They look like small tennis bats, clipped in,  lying on their side

Check if they’re all mounted correctly

Otherwise, it’s failing battery(s) in the tpms sensors
