Guys

who knows thsi one ...


Range Rover L405
5.0l Supercharged
2016 - milage 118,000+


All 4 tyres have just had new Land Rover TPM fitted

4x O/E LR TPM units fitted - 433mhz spec TPMS

New x4 Tyres also fitted

Part number: LR070840 J38AA - OE Jaguar Land Rover

Nicely fitted in alloys - 8 Nm tightened up

each sensor had a code ( 8 digit code ) which has been imput into the Snap on tool via the port

even put a TPM tool Reader on each wheel to check READ the codes ( see pic )

The cars been driven at 70mph motorway for 40 mins
reset Everything via Snap On Diagnostic Tool

still got the AMBER warning lights on to say the TPM system is at fault
x2 Amber lights


THERE NOTHING on the LR Display to reset the TPM system - just gives options on settings PSI and loads ?


now it came on to start with hence why I changed all the senors


I have even pumped the tyres up past the correct pressures then deflated fast to zero - then to correct pressures?


Snap on diagnostic tool says NO faults else where ?

Have you checked the Mhz they use?

Here is some info in the end of the description:

You can find out the frequency of your lock remote in the tech specification, or the inside of you keys.

Just a tip. Sorry if it was evident for you.

I'd try a different diagnostic tool, a lot of the generics that claim to do everything don't work 100%. Current

Hi tomiRR & andygts

Appricated you guys coming back to us.

Points taken - our Snap on tool is the top of the range
shows everything re: Brakes TPM specs required and yes they are 433MHz

Basically I spent 2 days on trying to figure this one out - even went to local LR main dealership - they had it for a hour and had the same problem.

Everything done - ie reads the wheel codes - assigne to each wheel etc etc etc.

and today - ITS ALL WORKING 100% perfect

guess how it was sorted - at my home on my own .........

The beast had to be disconnected from her battery for 4 hours ! - SIMPLE

I ve heard about folk talk about a Ghost in the Machine

maybe theres more to this than we know.............

So anyone reading this

ALWAYS disconnect the Negative battery lead followed by the Positive.

Then reconnect the Negative and LEAVE to Drain the Gremlins away

Remember / IMPORTANT

when Re-Connecting car battery:

POSITIVE FIRST

follwed by

NEGATIVE LAST


cheers

Oi! I resemble that remark!

I have no desire whatever to be “drained away” thank you very much!  “If it ain’t broke, don’t fix it” -where’s the fun in that?
