geoff, this will help you confirm if your vehicle has TPMS..

Thanks very much Bobby, I have valves 1 on the picture so TPMS. Seems not to be very sophisticated, I mean my old 2001 Mercedes shows a little picture of the car and the actual pressure in each tyre.
Still, I suppose it'll be helpful if I forget to check. Do you know how under-inflated the tyres need to be before it warns you?

Geoff

V.A. My wife is not feeling to good so I'm afraid I wont be able to make it tonight.
Will come next time.
Regards

Geoff

TPMS - System Operation

Each time the vehicle is driven, the TPMS module transmits a Low Frequency (LF) (125 KHz) signal to each initiator in turn. This is received by the tire pressure sensor which transmits a Radio Frequency (RF) (315 or 433 MHz depending on market) signal to the module. This signal contains coded data which corresponds to sensor identification, air pressure, air temperature and acceleration data.

The system enters 'parking mode' after the vehicle speed has been less than 12.5 mph (20 km/h) for 12 minutes. In parking mode the tire pressure sensors transmit a coded signal to the module once every 13 hours. If the tire pressure decreases by more than 1 lbf/in2 (0.6 bar) the sensor will transmit more often if pressure is being lost.

The spare tire sensor transmits a signal every 13 hours in the same manner as the road wheels when in parking mode. If the tire pressure decreases by more than 1 lbf/in2 (0.6 bar) the sensor will transmit more often if pressure is being lost.

As each wheel responds to the LF signal from the TPMS module, it is assigned a position on the vehicle and is monitored for the remainder of that drive cycle in that position.

When the vehicle has been parked for more than 15 minutes and then driven at a speed of more than 12.5 mph (20 km/h), the initiators fire in turn for 6 seconds on vehicles fitted with 433 MHz systems or for 18 seconds on vehicles fitted with 315 MHz systems in the following order:

* Front left
* 6 second pause (for the TPMS module to detect a response from the tire pressure sensor)
* Front right
* 6 second pause
* Rear right
* 6 second pause
* Rear left
* 6 second pause.

Each tire pressure sensor responds in turn so the module can establish the sensor positions at the start of the drive cycle. This process is repeated up to three times but less if the sensor positions are already known in the module. The process is known as 'Auto Location' and takes 3 to 4 minutes on vehicles fitted with 433 MHz systems and 7 to 8 minutes on vehicles fitted with 315 MHz systems to complete. During this period the tire sensors transmit at regular intervals, once every 5 seconds on vehicles fitted with 433 MHz systems and once every 15 seconds on vehicles fitted with 315 MHz systems. For the remainder of the drive cycle the tire sensors transmit once every 60 seconds or if a change in tire pressure is sensed until the vehicle stops and the system returns to parking mode.

Once the wheel position is established, the initiators stop firing a signal and do not fire again until the vehicle has been parked for more than 15 minutes. The signal transmissions from each wheel sensor continue at 1 minute intervals whilst the vehicle is being driven. This transmission is to monitor the tire pressure.

At 25% deflation the amber warning indicator in the instrument cluster is illuminated and an appropriate message displayed in the message centre.

Hope that helps! Malaysia Boleh!

Geoff, this all sounds very odd.

In addition, the UK-spec MY08 no longer included the 4.4 V8. I have a price list dated 13th Feb 07 stating that. So either you don't have a MY08 or it's not UK-spec (or both!)

Shame you couldn't get it to the pub last night...

Thanks very much Bobby, all is crystal clear now.
Shmoogle, It is not UK spec, I think now that it was originally destined for the U.S. but for reasons unknown it wasn't sent there. I cleaned and polished it yesterday - it is one of the best ways I know to examine every inch of a new car and it is absolutely without a blemish or sign of repair.
I suspect that U.S. spec cars don't have the headlight changing lever because it is so rare that Americans would take their cars to a RHD country.
The dealer I bought it from had about 5 RRSs for sale (one S/C), 3 Discoveries all new and 1 second hand RR Vogue, all LHD. The RRSs are all sold now. Their Name is Oakleaf in Northampton.
I'm also sorry that I couldn't make it to the pub but will do next time, definitely.

Good info on the TPMS. Glad i didnt get it . Only see it being useful if i get a quick puncture while driving.

Back to Adaptives..... I had those in my 07 TDV8 and noticed the headlights moving when driving around the lanes here but my 08 replacement doesn't seem to do that. Went back to the dealers and they illustrated the moving lights when starting the car....in fact they do that during the day when lights are off!

The side lights are good but the extra for full Adaptives the way they are now behaving seems a complete waste of money.

But can't get away from the fact that they are behaving differently then before. I wonder whether LR have changed there behaviour or another issue with the car! Rob
