Problem with Tyre Pressure Monitoring system (TPM)

[sidicks]

On Sunday, the TPM took a long time to register the pressure in the left rear tyre, but eventually did so. On Monday the same thing happened but with the right rear tyre.

I checked the pressures and reset the system but now TPM is stuck in 'learning' mode and no pressures are available.

I know that these sensors are supposed to last for around 6 years, so given that my car is over 7 years old (997.1 C4S) at least one of the sensors might need to be replaced but the fact that it appears that all 4 have failed at exactly the same time is suspicious?

Can anyone offer an explanation?

Assuming that I do need to replace all 4 sensors, what's the appropriate cost at an OPC (and how long does it take)???

Thanks

See the note at the bottom of this ad. http://www.oewheelsllc.com/TPMS-Sensors_5/TPMS-Sen... says all go approx the same time.

I dont know the cost from an OPC but the Beru sensors look to be £89 - £139 per wheel without the valve stem.

Last month I paid £560-ish for OPC to fit four new TPMS sensors and valves then balance the wheels - 997.1, OPC Reading, included 10% parts discount. They did it while I waited, it only took an hour or so.

I could've sourced the parts a bit cheaper online and found an independent tyre fitter to instal them, but it wouldn't have saved much money and I'd have had no comeback if (say) a sensor hadn't worked.

That's great really useful information, thanks.

£100 per year to have, and run, TPMS sounds expensive, doesn't it?

But potentially life-saving?!

Quite cheap considering you'll ruin a tyre after a couple of miles with little pressure in it and at £250+ per tyre...

I bought a set of four OE (Beru) sensors and valves from Tirerack in the US, £250 delivered!

Or alternatively check the tyre pressures yourself every now and again... with people sound be doing periodically anyways as Nitrogen slowly escapes from tyre walls, valves might leak, summer to winter conditions etc.

I agree that TPMS allows you to immediately detect a dangerous loss of tyre pressure, but then I think that you would be aware of this in steering / handling anyways: I recently drove a Citroen which bloody obviously developed a problem on the move. I recognised this immediately, I was able to slow down to a stop, check the tyres... Houston we have a problem and then get the affected tyre replaced. I don't think I would have identified the problem any sooner with TPMS.

I read in the online manual I use often for reference suggested the system is standard.

OP I see yours I a Gen1 too - is Tips standard fit?
Anyway to check or does it just say when there is a problem?

No it's not standard on the 997.1, 997.2 or even on the 991 (apart from the GT3).

The trip computer shows the individual tyre pressure at each wheel - very easy to see if you have the feature or not!

Yup, as I discovered I don't have when buggering around with the settings this morning sat in traffic.

From reading here, they seem to be a nice cost plus option that dissolves as per the OPC Battery around 5 years in to life.

As I said, mine is now over 7 years old and has saved me from a damaged wheel / tyre (or much worse) on more than one ocassion.

I understand these will be compulsory under some new EU law (from 2014/15 ??).

Standard on the Turbo as well.
