Rain sensor wipers are only coded in the front control module, whereas stop/start is coded in several modules. Hence why it is best to edit the vehicle data and do automatic coding for stop/start, as shown in Jeff's YouTube video.

Can you read Input Signals to the alarm unit with your Foxwell?  (On PST2/PIWIS you can see if the remote buttons are being pressed).  Does it have a Drive Links function, so you can actuate the solenoid with the Foxwell? 

Anyone with a PIWIS tester can do it. It doesn't need an activation code. The simple way is to just code it in the front control unit.

I'm a bit flummoxed.  After the fuse replacement, did a flat battery cause the problem to come back, or was it a random event?  Replacing the fuses seems to have reset things, so what happens if you repeat that process?  The battery drain won't be helping, so you need to get that sorted.  Are Bavaria Auto Werks in Aberdeen worth a try?  

The cruise control stalk is integral to the stalk unit, and isn't detachable like it is in the 9x7.

There are 40 variants. 20 for MY2013 and earlier, and 20 for MY2014 and later.  (The difference is the main beam operation).  The options that affect which stalk unit is required are; headlamp washers, cruise control, adaptive cruise control, voice control, and multi-function steering wheel, giving 20 possible combinations for each MY range.  

All the stalk units used to be a similar price, but now they vary from about £200 to £400, depending on the options.

Another thing to bear in mind.  If you have a MY2013 Boxster or Cayman built in the Osnabruck plant there is a campaign to update the instrument cluster firmware before it can be coded for cruise.  (11th Digit of VIN "K" = Osnabruck).

I think he’s basically done everything bar inputting the activation code.

Sounds positive then. Fingers crossed.

waiting for 9Apart to get back to me, they think they may be able to get a code for the part they supplied.

The code has nothing to do with the physical part. It is based purely on the VIN. 

When you buy the kit from Porsche, it comes with a voucher code.  The voucher code is entered into the Porsche system, along with the VIN, and it outputs the activation code. It also records the code on their records of the build data of your car on their system.

The Russian supplied codes are generated by a key generator which uses the same algorithm as the Porsche system, but doesn't need the voucher, and obviously doesn't record the vehicle data with Porsche.

Reece at MLR sounds confident that all he needs is the activation code and it will be set up.

If only.  It isn't as simple as just entering the activation code.

Get him to download the relevant Technical Bulletin from PCSS.  That shows the coding process.

In the past, I have bought probably 20+ codes from him and never had any problems. 

As for the procedure, I'm reluctant to pass on my hard earned knowledge to a company who are going to charge you to use it!  

I have his mobile number if you want to message him. Drop me a PM if you want it. 

I used codes-porsche when I was doing cruise retrofits (pre-war). He is based in Moscow. There is a specific routine for entering the activation code, and coding all the relevant modules. Make sure they know it before they start, otherwise you'll be disappointed. 

Possibly the brake light or clutch switch. Even if the brake lights are working, it could still be the switch. If you have access to a Porsche-specific tester, you can view the state of the switch contacts - open or closed. 

As @Paul P  says, it depends on the software version.  iPhones use the rSAP protocol, and if the PCM firmware is prior to v2.23 and you have the i666 phone module fitted, it isn't compatible, as it only supports HFP.  There is a workaround if you have the phone module and older firmware.  If you "un-code" the phone module with Piwis, it has the effect of enabling i619, 'mobile phone preparation' which supports HFP and rSAP.

To check the firmware (although Porsche call it software) press INFO and SOURCE at the same time.  The firmware can be updated to v2.25, but if you do that, all the map data will be unreadable, and you have to install later maps (at a cost).

One of my heroes, with a "Riverdance" of heel & toe and left foot braking. 

As far as I know it is in the instrument cluster.  There is a loudspeaker test you can do with Piwis.  I expect it uses the same speaker for the tick-tick of the indicators, and the warning sounds.

Seems like some of the early systems do it. 

EFA.....

I get delay on mine, so doesn't sound right 

What Model Year is yours?

I had a 1998 996, and it did exactly the same. Seems like all the early systems do it. 

Here is the airbag wiring diagram for the 2004 986:

<2004 986 Airbag Wiring Diagram>

I can now see that your ride is a C4S, but I had already uploaded the diagram before logging in.  Here it is for the C4S:

<2003 C4S Airbag Wiring Diagram>

Either way, you can see that there is a +ve and -ve connection to the airbag.  Now you need to figure out which is Pin 1 and 2 on the airbag plug.  They are usually marked somewhere in the moulding, but have a magnifying glass handy.

The startup test measures the resistance of the airbag. About 2.7 ohms iirc. 

I'll check the wiring diagram tomorrow morning when I get to my PC, to see if it gives any clues.

Diagnosis information POSIP

POSIP triggering unit

Diagnostic conditions:
* Ignition on
* Internal function test completed

Possible fault causes:
* Plug connection/wiring faulty
* POSIP triggering unit faulty

To be honest, I'm not sure which elements of the coding can be changed.  When fitting a new airbag triggering unit, it is coded, and then "locked".  I am pretty sure you can change most of the coding values (thorax/steering wheel/pre-tensioners, etc.), but I don't think you can change the vehicle type (911/Boxster/Cayman), the VIN number, and the hours counter.  A new unit is £1000+, so it is worth taking a gamble on a used one, but I would give yourself the best chance by getting one from a model as close to yours as possible.

I find that I only use the revering camera on my Audi is when it is dark, or nearly dark.  With the reversing lights on, it works better than my eyes.

@Richard Hamilton wrote on this a while ago, I believe he indicated that milage can only be increased.  I'd do a thorough check on the eBay seller's credentials and feedback before sending anything to them.

Not quite. IIRC, I wrote about new instrument clusters, which can only be wound forward with PIWIS, but once set cannot be changed. 

With the right software, you can adjust the mileage up or down. Illegal if you are misrepresentating the true mileage of the car, but perfectly legitimate in this case. Most of the "mileage correction" people are distinctly dodgy, by the nature of what they do. 

If you Google "mileage correction" you'll find dozens of them, and they will come to you. 

@Paul P  is correct here.  Switch ignition on, then off, but don't remove the key, before disconnecting the battery.  The alarm uses Terminal 86S (Key in Ignition), not Terminal 15 or T86 (Ignition on) to detect if there is a supply to the alarm siren, allowing the battery to be disconnected.  Leaving the ignition on also works, but you get a bigger spark when you reconnect the battery.  😀

Maidenhead, Berkshire, if that's close enough, although aiming to move to Princes Risborough in a couple of months.

Drop me a PM if you want to give it a go.
