PIWIS is the dealer diagnostic tool/program. 

The fact that it's showing hot after being left overnight points to an electrical issue vs a mechanical one. 

Any garage with a good diagnostics tool would be able to pull up live temp readings from engine, coolant and ambient air. Thing is, best to do that whilst car is cold. That way you know easily when a temperature is implausible. 

I wonder if the temp sensor is playing up and the car won't start as it is reading too hot. You need someone with PIWIS or similar. Have a look on the forum if there's anyone on the forum who is nearby and could maybe help. 

Sounds like an electrical fault to me. 

My money is on the MAF. 

I wonder if using clear silicone grease on the surfaces would be a good idea to keep the two different metals isolated from each other. ACF50 grease is petroleum based and would swell the rubber and o-rings so can't use that.

Made a start on the crossover pipes. Fiddly but not difficult, about 2 hours to get everything out, now need to clean it all up before putting it back together again!

Could you tell us a bit more about the process, Adrian. I'm looking to do this in the summer on my car and a friend's 911.

Flat spots are an easy fix for a competent wheel refurbishment company. 

Is an actual buckle or a flat spot on the inner part of the wheel. 

Is it too late for this?

Thanks, I did pop into halfords and all they had was cherry flavour.  I might see if euros do it as there are no costcos here.

Funnily enough this issue is driving me crazy with my i3.  No engine, no heat = frozen washer jets all the bloody time!!!!

I had to stop this morning, in a forest, in complete darkness and pour screen wash from a 5l bottle over my windscreen.

Very simple solution to this. Use proper low temperature screen wash. Costco or Halfords is a good place to buy. In this weather, it should be put in neat as per instructions. 

I previously bought aftermarket, good brand, bonnet struts and they were no good. Basically, they were too powerful and NOT two-stage like the original Porsche ones. Funnily enough, a friend that has a 997 had the exact same problem with aftermarket ones he bought. 

The aftermarket ones only have one speed and stop abruptly and put too much load on the hinges. 

The genuine Porsche, which are made by Stabilus, let the bonnet go up fast but slow down for the last few inches of travel and stop softly. 

My advice: don't take a chance with aftermarket. Buy Stabilus (from Frazerpart) or genuine from an OPC. 

I'm sure the coding just involves telling the ECU what type of Porsche it's being fitted to - targa, coupe, Boxster etc. 

@Richard Hamilton is the resident guru here and could likely confirm this. There's a list of people on the forum who have PIWIS who could code a new one for you, if need be.

Where is the best place to source them folks?

Better with titanium than stainless steel.

As I understand it you will at least be lowering the subframe on its bolts otherwise you can't get the pipes in and out.  Anyway, best of luck it is always good to be ahead of the curve on a potential failure point.

I think it would be easier to lower the subframe using threaded bar that matches the original bolt threads. That way you can lower more without any risk of the whole lot collapsing etc.

I saw a technical bulletin the other day which said you can code our the time updating via GPS with PIWIS, and set the date and time manually. 

Any ideas where we could get a hold of this TSB, Richard? 

Probably best to look at any for sale on ebay to see how the clip system works 

Are they not just standard VAG sensors which are made by Bosch? 

What brand of tie rods have you been fitting? 

Was just thinking there, what if you set the clock to 2005 - when PCM 2.1 came out - and see if that makes a difference to the timekeeping. 🤔. I'm more interested in the time as opposed to the date, in the car. 

We need a @Richard Hamilton to help us with this. This clock issue appears to affect cars worldwide. Poor show by Porsche in not looking at keeping these things running correctly past a certain timeframe. It really should be an integral part of developing software for the PCM where you go through all scenarios that are inevitable. 😡
