I do not think it adjusts unless it needs to. If the sensors do not see any change then there is no need to adjust.

You can read the function description in the Technik Book for the 997-1 here -- starts on page 173.

@Loren where can I find a copy of the Technik Book for the 997-1?

Initially I believed this as I lost the date around Jan 2 2019. But after meeting up with many other 997 owners they have the correct date displayed. Recently my time will not stay sync'd. I'm betting my PCM is starting to fail and its not related to the GPS rollover.

I am beginning to believe this as my mrs had the whole system shut down on her the other day.

HUR on the way.

I 'think'this is related to the GPS rollover that happened recently. There are only so many weeks in the GPS file structure, the field that contains the week number is a 10-bit binary number. This limits the range of the week number to 0 – 1023, or 1024 total weeks.

GPS week zero started January 6, 1980. The 1024 weeks counter ran out and rolled over on August 21, 1999. The week counter then reset to zero, and it has been recounting ever since. The next rollover to zero was on April 6, 2019.

Units need a firmware update.

Porsche have deleted the date when you update the software as a work around.

What is a top mount btw?

Top shock mounts, front and rear they degrade over time too.

Sorry should have explained better.

Don't forget that mounts wear out too, new engine and gearbox mounts will make the car feel better.

New top mounts as well.

Re build looks ace.

Why not just get the lead back from your friend?

I would be very unhappy if someone borrowed my kit and didn't return it.

Cabs are quite well known for holding water behind the rear seats, this gets into the electrics, i have pasted a very useful thread below, but if you search on here a little further it is pretty much explained in other threads too.

Welcome.

Where are you in the UK?

I am from Bristol, 05 997c2s silver.

I have just done the trunk release exchange. Taking the door sill out was easy thanks to the hints described here. But removing the switch module from the sill was real challenge. Forget the picture posted by Loren. I have tried everything and at the end I found the trick. Lay the sill on the table bottom up. Then you need a very narrow screwdriver 2 mm and you need to push it between the hold tabs of the module. There is s little space there. Just push it straight down and it unclips. There are four of tabs, two on each side. Instalation is very easy, just push the new module to the place until it clicks.

I used a wide thin trim tool, tricky but it works.

Grant,

I hope you enjoy the car.

Managed to use the PIWIS to cycle the solenoids and check the wiring. Alla seems good. No obvious damage.

Work has meant that I haven't yet got to look at the car, the wife uses it as her daily.

The check engine visit workshop hasn't come back, but I am still going to check everything as soon as I get the chance.

Thankyou. You guys are great.

I will check the sensor and wiring to it, on the front of the engine and the brackets and wiring for the two on the cam cover.

Thankyou. I will take the mufflers off and have a look at the bracket suggested by jfp and jl-c.

I would take a close look at the sensor retaining bracket, we see these things snapped off pretty regularly:

 

 

 

 

 

I think you are on to something there.

Thankyou.

This is what it should look like, as you say the cable clip is supposed to be part of the sensor retainer bracket.

Thanks that is it, where is the picture from?

In all of the three above, the difference between the actuals and the specified isn't the same as the deviations?????

The deviations are staying at static values.

I am Confused.

A few more revs

Thanks, I didn't have the time to take the exhaust off, so did what I could in the time available.

The muffler and hangar are going to have to come off to get access.

I will bet it sounds great with it off mind .

Idle, both banks.

The connector.

I didn't short the connector. Or check the resistance of the sensor.

I've put it back together now.

I can't see how to get the sensor out without dropping the exhaust and I have to get to work.

The clip.
