£800 for new TPMS wheel transmitters.

TPMS on constant "Learning" - turns out one sensor has a dead battery. Porsche claim it's not possible to replace the power unit. The car is 8 years old so expect other 3 units to die imminently. Total cost £800! Really?

Hi you have to replace both on each axle, as they have been modified, so you replace fronts first and programme to car.

I had to replace all 4 on a 997 Turbo to get system to work.

You shouldn't have to. I have replaced just one before

[berty37]

I had this on my old 997 turbo too. They are just filled with batteries thats all that eventually die and yes you have to buy the whole unit - you do not have to replace all 4 it is true but your dealer through the Porsche diagnostics can tell you how much battery life is roughly left on the others.
I ended up ordering mine on TPMS.com much cheaper than here in the UK especially from OPC's and i got the Huf/Beru brand which are the Porsche OEM ones. There are a lot cheaper ones but I had heard stories of them not linking well with the cars systems. I got a local tyre fitter to put them in for me and saved lots of cash only word of warning..it took quite a while before the system learnt all the sensors again and the dash warning light went out..hope this helps.

I believe that they have an expected lifetime of around 7-8 years, so while you don't need to replace them all at once, if the car is 8 years old then you would expect the others to fail soon.

Exeter did mine on my 997 C4S for around £400, when most were trying to charge £600.

A bit of negotiation with OPCs should see the bill reduce.

I got a set of Titan TPMS sensors from the US for around £120 a set of 4 for my winter wheels on my 981 and they work just fine.

I think they have sets for 997 so perhaps worth a try? Do a search on ebay and select worldwide (ask the seller if compatible to confirm)

Edit: Don't see them on ebay now

Here's a link to them direct... perhaps email them?

Bought mine here http://www.tpms.com/2008_Porsche_911_Turbo_TPMS_s/...

Got them in my spare wheels and gave done for a year so far with no issues, would replace my OE ones when they go too

Cost about £250 for 4 with valve stems inc. import tax

New sensors all show 96 months battery life on my car. Would therefore assume 7-8 years is about your lot.

[R1nur]

Thanks guys. Some great advice and ideas. It made sense to change them all because as you kindly pointed out the life expectancy is 7-8 years. The diagnostics showed only a few months each on the remaining 3 wheels.

However the OPC has come up trumps and done the lot for £200.

Bargain, first time I've heard an OPC do it for that price!!!

How did you manage that buddy? Mine is due in later this year for major service, warranty renewal and the TPMS need changing.

An Indy tends to quote around £600 ex VAT - your £200 is amazing. The best I've got from an OPC is £603 inc VAT.

Well done
