I've got an intermittent glow in the TPMS warning light. When connecting the IID Tool it shows 100KPa on all 5 wheels.
Being an idiot I cleared the original fault codes without properly storing them, and sinsce this, the fault codes that were present on the TPMS has not re-occured.
IR-receiver? TPMS Module?
Obviously I'm not driving around with 1 bar in each wheel. 2007 L322 3.6 TDV8 Stornoway

No thoughts? Likely to be the receiver?
Seems the system is waiting for the wheels to sync. I've just bought the car, so for all I know, all the five batteries are dead.

Where on the IID tool do you get this screen? 2012 TDV8 Vogue SE 4.4

Where you choose live view values. You can also choose the spare, but it's on a separate window and not in the graphic. 2007 L322 3.6 TDV8 Stornoway

Minor update. After driving a few hundred miles I've gotten the fault codes back on the TPMS.

Each wheel shows code C1A56-31 (E8) (individual Wheel codes, 56, 58, 60, 62).

A more interesting code that appeared is from the receiver above the sunroof panel.
C1D19-87 (28) External receiver data line - Bus signal/Message failure - Missing a Message.

So I'm hoping this module would be the issue. 2007 L322 3.6 TDV8 Stornoway

Another minor update.
I've replaced the receiver above the mirror - no change.
Replaced all wheel sensors - no change.

While doing a different repair, I found one of the antennas (front, left) was missing. I've ordered a new antenna, but surely this wouldn't cripple the whole system?

Seems I'll be in the market for a new TPMS module in the future. 2007 L322 3.6 TDV8 Stornoway

My TPMS works usually when there is an R in the month.......useless system.  David

Please let me know if my comments upset you, I may wish to upset you again.

If that’s Lbs/Sq” the tyres are a bit over inflated 😂 David

it's kPa. Though I'm not certain it's accurate. Will have to check.

330 kPa is still 48 PSI, so a bit over inflated. I also think the front/rears have swapped position, as the rears should probably have the higher pressure.
