TYRE Pressure Monitoring System - FAULT ( TPMS ) | |
Guys can anyone sort this one out .............
so now 2 Months on
with either the
Range Rover re-calibrated ( Factory reset with Snap On Tool
OR
Reset with Land Rover dealership diagnostic tool
I get this fault:
The car runs perectly for around 50 to 200miles ( motorways & A roads ) with NO amber TPMS warning lights coming on.........
THEN for what ever reason the amber warning light comes on - fault ?
so stop the car
Snap on Tool comes out - into the `ECU port - FACTORY RESET EVERYTHNING - takes about 5 mins
Start the car and is all perfect again for around 50 to 200 miles
Then it starts all over again !
Now I have purchased all new parts for the TPMS as below:
1) Purchased Brand New TPM Senors x4 from LR dealeship
( £600 ish )
2 Purchased Brand New Landrover TPM reciever ( £ 150 ish )
3 Calibrated all 4 wheels / TPMS with Snap on Tool - all OK
4 Purchased another Brand New Range Rover car battery 900 amps - so voltages are spot on ( £ 380 ish )
5 all x4 tyres on Range Rover are brand new ( 3,000 miles so far )
Ranger Rover has been reset and all x4 TPMS codes have been entred - all correct
Tyres are at correct pressures
Tyres are correct ie `MINT condition with 7mm tread
Tres are at the corrcet Tyre Pressures - handbook checked
Is there such a thing as a " Ghost in the Machine "
I have even had the main battery disconnected for 2 days with the Earth Lead only attached
to ensure no static or current is left in any of the ECU's
Everything else on the L405 Range Rover is 100% perfect - ie NO other waring lights
It's just this TPMS cant seem to play ball
IT WORKS WHEN Reset FOR 100 or 200 miles - then all of suddend on the motorway travelling at 70mph it comes on - saying Fault ??
IT IS WORTH NOTING - There is NO spare in the boot
would appriciate help on this one.
