7. New battery - antigravity lithium battery already purschased

Am I missing anything?

 

Brake fluid flush and maybe break down, clean, lube the Centerlock bolt internals.

 

I just did a PDK Flush pretty simple. Not a bad thing to do if you track.

 

And if you have a Manual, don't forget to flush the gear oil every 96,000 miles

 

What’s a pdk?

 

Any advice on the tensioner roller?

 

One item I would add to the OP's list is while you are changing plugs, change out the coils. The labor is the same, just the extra cost. I cannot find anywhere an estimated service life for coils, so I change them every two years. If you drive hard, the coils will melt into the chamber causing a boatload of angst to remove. Keep the spares in your tool kit, you never know when you or a friend will need them at the most inopportune time.

 

I replaced the tensioner with belt. Kind of a 3 hand job, but straight forward. Mine was leaking. There are some pics in Tom from TPC journal.

I didn’t do my coils when did plugs last time, should have because I just did them.

These maintenance items a fairly straight forward if you have the tools, time and ability.

Its also a great time to clean and inspect.

 

How do you reset the service light reminder when you DIY?

 

iCarsoft POR V3.0 for Porsche/Cayenne Diagnostic Tool with auto VIN/Quick Test/Actuation Test

 

Will this reset the air bag light swapping back to stock from the track?

 

Believe all SRS lights need a dealer visit to reset.

Not sure what you mean swapping from track?

 

Keep all parts receipts and self-maintenance log of dates and mileage of services performed. If I come with those things, dealer resets for free...

 

It's a device that helps improve lap times and prevents money shifts.

 

You can inspect the tensioner from underneath the car by removing the bottom skid plate. If it's not weeping (leaking) or oily, it likely doesn't need to be replaced. But the best test is to remove the air box and check the tension on the belt. It's cheap enough that I would recommend having the part ready just in case. From my experience working on my friend's 991s and my cars, that these can start to leak after just a few years, regardless of mileage. I just performed a 4 year service on my 2015 GTS when it had 19k miles and the tensioner was weeping already. I'm planning to replace the tensioner on my RS when I perform the 24k mile service likely at the end of this year. There is dirt gathering on it, which is a sign that it's starting to weep fluid.

The process of removing the bottom torx bolt can be difficult if it's your first time. You just need a very short/shallow torx socket to get between the bolt and the rear engine frame.
