Interesting new bulletin on TPMS valve sensors. Apparently, they can break and leak air when removing dust caps or checking tire pressure? What is interesting is that Land Rover is instructing its dealers to replace all 4 or 5 sensors, not just the broken one(s)... :think: There must be an issue with the sensors installed on current cars (06 through 09, see VIN range in the bulletin), otherwise I don't see why Land Rover would go through the trouble of replacing all of them, considering their cost and the labor involved.

Note (this was issued earlier as a Special Service Message), no metal caps on TPMS sensors! If you remove the plastic dust cap and put a metal one on, your warranty on the sensors is instantly void.

What does the metal cap do that the plastic one doesn't? Does it somehow send a false signal to the TPMS system?

Paul, I think Land Rover is worried about potential corrosion caused by a metal cap tightened against the aluminum stem of the valve, possibly making removal of the cap difficult without breaking the valve.

:!: Wow, that is serious $. "Hey I have low air in one of my tires." LR: "No worries, we'll just replace all the TPMS!"

You're not missing anything, its only a light to provide idiots who want to drive 25 miles with a flat with a second opinion as to what the loud whump whump noise is.

true. it's really not that much. i think it fires when you're as little as 5 lbs off the recommended psi. beeps and displays prominently when you're aired down. it'd be at least more helpful if there was some indication of which tire it's complaining about b/c some times i've noticed it can be a little fickle.

I noticed, in the bulletin, that it does not account for re-balance of the tire after installation of the new sensor. I would suspect that the dealer will require the customer to pay for the re-balance, not cheap. And since the tire needs to be removed, a re-balance is needed. Helps up the dealer income.

Also, be careful what you wish for. My low tire light comes on in the winter with only a slight 4 pounds difference due to temperature. Pain in the BUT!

Thanks for the info.

I have the TPMS on my 2006 as well as some other 2007 features. My car is Sept 06 build with delivery in Feb 07. Probably one of the last 2006's off the line.

The referenced workshop manual instructions for low tire pressure sensor replacement call for routine spin balance of the wheel at the end of the procedure, so they should not charge extra for balancing.

The TSB forgets to mention that, should the full size spare tire sensor also be replaced, driving the car all the way to Timbuktu will not cause the TPMS module to "learn" that sensor, since each new transmitter needs to roll as a driving wheel for a certain amount of time, at a certain sustained speed, to be detected. I guess the dealer will figure it out on its own.

i wonder if they'll cover us on 18s. i did notice an "aftermarket tires" remark on an older service write up.

Good point Phil. My guess is they won't, since while the rims are Land Rover the tires are not of the approved profile. Maybe if you bring enough donuts when you check in...

So is this something they will replace regardless of an issue - more like a recall?

What if we are out of warranty?

You'd have to show up with a defective sensor, it's not a recall. If you are out of warranty, you are screwed.

I should probably remove my Tireflys before taking the Sport in for servicing then?

Paul, if you're looking for a retrofit kit, I've heard Orange makes a nice one for about $150.

Had a further look at this again, overall seems like a slick setup, but then you have to run the wire to a cig lighter to get 12V juice. Wonder why the display unit cannot also be run on a lithium battery like the sending units. Would be nicer if I could get this hotwired somehow and run the wiring back thru the console...otherwise more cables dangling around.

Decisions...decisions...
