Cheers.

I've made a note of these for when mine fail.  Hopefully they are the ones that should last 10 years.

I've done a bit more digging and spoken to a couple of OPC's, tyre places and an indy:

The original sensors 7PP 907 275 B or RDE011 have a 96month/8yr life when fitted and pressure applied (tyre inflated) The new sensors are 9A7 907 275 06 or RDE048 and have a 10 yr life.

The OPC price breakdown is £133 for the sensor and £19 for the valve. £613 if done when replacing the tyres. TPMS warehouse are £86 for each assembly (RDE048) which are made by Huf.  Design911 also do replacements, as do many other suppliers.

The OPC can code them when fitted, but they advised you can just drive a mile or so and the car will update itself.

The sensors are not a warranty item as they have a battery installed.

My local tyre place say that changing the sensor can easily be done. It is not an issue.

I will be changing my tyres soon for Michelin's, but will wait to do the sensors until I get a warning light on the dash.

HTH 

 

Thx TT

when you say “The new sensors are 9A7 907 275 06 or RDE048”  does that mean these are interchangeable, or do you need to find out which yours are and it will be one or the other of these types?

My 2013 doesn't have them fitted. I think the regulation only came in from about 2015 for them to be mandatory on cars.

Right, maybe that explains it then.   
 

I guess as far as necessity it depends how conscientious you are checking your pressures, I wouldn’t want to go on a spirited drive without knowing my tyres were as expected. It does also give some indication of how warm the tyres are as you see the pressures increase a few psi with use.

I knew about a set of tyres, 6 year service, aux belt and brake fluid this summer.  Just didn't expect to have to change the TPMS sensors, as had been led to believe you just replaced the batteries.

Please update us if you do change your sensors, especially if you use any aftermarket option.

My car is a year older than yours (2015) I had my 6 year service back in Feb and no indication by the OPC of likely imminent TPMS issues.  As you say, there are plenty of 2012/2013 cars around and I’ve not seem much talk of these needing changing yet. So in your case if they do need changing that would seem a bit early to me.

Apparently insurance prices are down significantly this year (according to a newspaper article i read), so if your renewal is higher I suggest you shop about. I suspect claims were well down in the past 12 months for obvious reasons.

Looking at the links in Daz youtube description it looks like:

Ballasts.  £35

Bulbs used by Daz £50

Nightbreakers Bulbs £75

The the Nightbreakers and the ones Daz uses are both 35w. So I can’t see how the difference would be Night and Day. (See what I did there!😉)

Seems like a decent improvement that Daz.  
 

I've got to admit I’ve have never really had an issue with the standard Xenons in the S, but then I don’t tend to have spirited drives at night.  Will be interesting to see if you have any MOT issues. 
 

As far as the ballasts are concerned does the ballast have to match the bulbs exactly? I.e. if you changed back to the old bulbs would you need to change the ballast back?

One thing for sure it seems that they will all fail at some point

Humm...not sure that’s true.   Although it does seem there is a higher failure rate than you would like there are plenty of higher mileage 981s and 991s that haven’t needed a change.

Maybe the weather access is a failure reason I don’t know, what was suggested to me by the OPC technician was that the design had been tweaked to solve the issue, so certainly extra weather protection is something that could easily have been added, but how much truth there is in this I can’t be certain.   I am hoping that there has been a tweak as that bodes better for my situation having had both replaced.

My take is the 981 GTS cars seem to be more susceptible to this than the earlier 981s there definitely appears to be a bad batch circulating around the 2014/15 build dates. Plenty of early 981s have sports chrono fitted but there doesn't seem to be the same failure rate and certainly not so early in their life. When I've seen failures on earlier cars they have been at higher mileage.

Not sure on the 718 cars.

I suspect the only reason for GTSs seeming more susceptible is that: all GTSs have sport chrono; GTSs started around the time that there appears to be some dodgy batches.  So I suspect a similar year standard car with Chrono would have just the same chance of failure.  
 

Note: I have a ‘15S  and have had both drivechain mounts replaced under warranty. I’ve had no issues with the replacements.

I’m not I huge fan of the 911 ducktail look ( I know, I know) so I didn’t think id like this, but actually in down position it looks fantastic, up position, who cares you don’t see that yourself.     
 

I assume you ordered it and then had it painted?

Roads must be bumpy up there it’s caused your number plate to fall off!

Yeh looks like bushes could be a likely culprit if that thread above is any guide. One other thing that does occur to be though is tyre pressures. In particular if you have different pressures on your rear tyres, this tend to confuse traction control systems.

Porsche’s (and many other modern cars) are pretty sensitive to voltage level and low voltages cause a number of sensors  to misread -> mayhem.  Looks very much like this is you issue but for some reason the lights are not resetting. Would be very unlikely you had genuine PASM and PADM issues at the same time (unless a control module was flooded or similar).   I expect a PIWIS reset/clear will do the job here.

Good news is that warranty isn't essential in these anyway (touch wood)

You might think otherwise if you have what happened to this guy happen to you.

suspect the likely outcome will be to stick with what I have but always interesting to get a different perspective. Extremely unlikely but has anyone ever switched to a Maserati GT, in particular an MC Stradale? I suspect not given its a completely different car, but it is my favourite car on looks and sound but fear dynamically I may be disappointed after a Boxster....

It depends what you want from a replacement.  If it’s something as good dynamically then Alpine or Lotus,  if it’s something more GT than the maser is a great option and sound epic, other option being F type V8.  Getting the same useability,handling,looks combo is IMO not possible.

It’s a much higher spec than most GTS examples. PCCB, Burmister, PTV are very rare options and on their own around £10k.  For someone after these there won’t be many to choose from.  The most expensive examples are those newer model years with low mileage. Yours isn’t especially low mileage. All in I think you might just acheive low £40k, but likely late £30k.  You do see some GTS under 40k but they usually are very strange spec or high mileage.

It wasn't the vacuum unit it was definitely the plectrum shaped piece which had some surface rust and tried to attach itself to the exhaust.

Right, I’m pretty sure this wasn’t the case with mine and I resorted to spraying lubricant inside the actuator unit, so hopefully in your case it’s easier to keep it loose.

Went to check my PSE valves and of course one of them was a bit stuck! Some penetrating oil and some persuasion with a mallet for a few minutes and all was well. I can't stress enough how important this is folks! Nothing worse than a PSE not meeting expectations after lay up!

My old video on the subject is linked here if you need any instruction on how to check them.

Any questions let me know 👍

It will be interesting how often you end up having to do this.   I got to the stage where I had to free them up almost every week.  They would then work for a day or two before ceasing again.  I tried various lubrications solutions but none seemed to work long term. I wonder whether the actuators have some sort of coating/gasket on the plunger that wears off over time?.   I had mine replaced under warranty last autumn but otherwise I’d have been investigating these:

The functionality to switch on and off is nice if fitted but it's very seldom i would turn it off, coming out of sport mode (button still on) and being gentle keeps it quiet in built up areas.  Has anyone considered opening and modifying the back boxes of the standard system, you'll pick up a spare on ebay for buttons if you want to reverse.  I would try that before spending £1850.  

Probably depends a bit on your usage.  My car is a daily so I use mine in quiet mode regularly. Also if you do motorway mileage much you might find the quiet mode preferable (especially if you have PDK).  In addition I think when they program the PSE on the switch using PIWIS it adds a map to slightly over fuel on overrun when PSE is on - hence much more pops and crackles than otherwise - one reason perhaps why Carnwell users report fewer pops and crackles.

You could get a Spyder for the same money...no brainer surely?

I don’t think it’s quite that clear cut (assuming either were available).  With the engine being all but the same there’s no real obvious advantage there.  The roof is a big turn off for some with the Spyder, a point for the GTS/25. Suspension wise clearly the Spyder is more advanced/tuned, but again this isn’t always a pro, some want more compliance in a primary road car.  Both are limited edition models though the Spyder will probably have more cache (if that’s important to you).    Never driven either so obviously pure speculation but I don’t see a chasm  between them and could certainly see some preferring the ‘25’.

I’m quite liking the look.  Wheels look good IMO,  side vents I’m not so sure.  I don’t know if I could live with red on the top of the dash though (reflections). Ultimately though is just some cosmetic treatment, so I can’t really see a huge premium being maintained over a similarly specced GTS...but I’ve been wrong before.

You can keep the old one if you wish, although transporting it back in the box would be entertaining.

With some old blankets and a distinction on your ‘packing’ diploma you can get them on the passenger seat.

As for value, negligible as modern standard exhausts last 10+ years by the time it's worth something yours will have rotted away too

This.

You do see them on eBay but they are usually £150 or cheaper. There’s just no demand except perhaps the odd person that wants to try a Carnwell or similar.  In another 10 years they may be worth something.

I quite like them in that type of car.  I always like a Lambos in obnoxious colours as well.

I haven't experienced the standard exhaust but from the first test drive of the car I bought (2.7 with PSE) I actually found the noise quite subtle.

Still do in fact... for the normal driving... the pops and crackles are great but outside of that it seems a bit quiet unless up the rev range.  I wonder if changing the air filters next to add some more noise...

For reference I've come from a rather special S1 Elise with a Larini Club Sport exhaust so perhaps I'm just used to something more 'racey'

 

Yeh it’s true that in tootling Rev ranges the PSE is pretty subtle, but has a lovely roar over 4K revs.

didn't realise this.  "Note- PSE in quiet mode is still louder than the standard exhaust." just read that in one of the previous posts I've always thought it sounds lovely even when switched off,

Maybe my post.  I can confirm this is the case having had both on the same car.  It’s no surprise when you see the units as the PSE unit has a smaller overall silencer volume due to the actuator/switch paraphernalia, so even when in quiet mode there is less silencer volume in use.

Unfortunately the old back boxes don’t hold much value as no 981s are in a position to need their standard exhaust being replaced (due to corrosion etc) so currently value seems to be £150 ish.  Maybe in another 10 years they may gain some value.?

As stated above though, a significant part of the install (and cost) is installing the vacuum tubes, engine switch, wiring, console switch and programming etc.  All this could be left in if you put the old stuff back but you would then have an exhaust button that didn’t do anything, and yes I expect it would mean you couldn’t then extend warranty. 
 

Looks like Ringmaster is going to have to drive around annoying his immediate neighbours for a couple of weeks!!
