DTC Codes with no warning message

[scottjk]

I'm a new 991.1 owner. Is it possible to have stored DTC codes without getting a warning message on the cluster?

Yes, all depends upon what the DTC is for.  Get the car scanned with a Porsche specific scan tool (PIWIS, Durametric) and report what is found.

I am not a fan of that scan tool as it is know to produce incorrect or even non existent codes at times.  I'd suggest getting the vehicle rescanned with a better tool.

Good to know!

 

I'm looking at buying another Durametric or PIWIS II. I'm not sure which one to buy. Is there a preferred vendor for the PIWIS? Being a 991.1 I'm assuming I don't need version 3. I also see a lot of clones that potentially concern me.

The Durametric system is excellent, but cannot do everything that the PIWIS system does. But as for the PIWIS, you cannot purchase a legitimate system, only lease them directly from Porsche.  And the first year's lease is $20,000.  Any PIWIS units being sold are illegal clones, and could be the older systems which may not fully support later car's such as yours.  Also be aware Porsche can actually reach out and kill some clone systems remotely as well.  After the earlier debacle with illegitimate PST II systems, the did their homework with the PIWIS, which also now includes their entire library of factory service manuals online as well (Porsche stopped all publications of service manuals around 2005).  While the PIWIS is a terrific tool, it is very difficult to justify financially, even for a shop.

Good to know. Durametric it is.

Thanks!

Looking through Enthusiast VS Pro I noticed the 991.1 doesn't support coding. Any other reason to buy Pro other than unlimited VIN?

The Pro version does several things that the enthusiast versions do not, such as activation of the cruise control system post delivery.  As for coding, two points to remember: First, Durametric is always in a "catch up" mode; Porsche offers no assistance so they have to reverse engineer all of the DME computer codes, so they are nearly constantly adding features as they find out how to access and manipulate them. In recent model years, Porsche has switched DME versions and even suppliers (Bosch to Siemens) on some models, which creates even more things to have to ferret out for Durametric.  Secondly, Durametric is a "standalone" system that needs to be manually updated once the code is developed and tested, Porsche meanwhile uses a networked system for the PIWIS; they change the code at the factory and the next time you turn on your PIWIS, it is updated to current automatically..

 

For probably 90% of DIY end users, the enthusiast version is sufficient, plus is you ever need to go to the Pro version to get one of its unique features, you can update your system to the Pro version for a fee.
