The only source for OBD II code data for a 991 is in the PIWIS system (Porsche stopped printing this type of data around 2004 model year).  It can also be obtained through their online subscription service, PIWIS Tsi.

So why does Durametric not publish it?

If I went to the PIWIS Tsi site, there is no reason I cannot relate what it says online.

Anyway JFP, no worries.

Well that does not alter the fact that the information given by the Durametric provides a code to an issue and since nobody knows what it means, it is useless making the tool an expensive paperweight in many cases.

But you had me look. My 993 OBD II manual does have it, but for that model of course and not my 991.1.

I've have bought both Durametrics so far with the Enthusiast Version initially that I sold to a friend and now the Pro Version.

I've done extensive searches but with the internet as big as it is, I have not come across a site that tells all as far as Codes go.

I know all about P codes, U codes, etc that anyone can easily find meanings of on the web. The Durametric comes up with codes that aren't, such as in the Instrument Cluster 41510 / a226 and countless others of that format.

I remember asking Durametric ages ago what all those non-OBD codes meant. They didn't know, so of what use is this diagnositic tool? It is the most expensive diagnostic tool I have bought and it does the least by far in comparison to other diagnostic tools I have bought and still own.

This was a long time ago. Any update as to what it was.

I would have used a stethoscope and listened to various parts of the engine, both on top and below. I know noises can travel in an engine making it difficult to pin point it, but it might help.

Need to see an image.....……………..

Check out this Youtube video at the 5' 50" mark...

ECU Interrogation using a Durametric Diagnostic Tool

Looking at a YouTube video of the Durametric at a feature called Rough Running, Cylinder X, what do the units mean.

From what I can make out, it looks like 1/s^2 or l/s^2.

Durametric has to walk a very fine line in their diagnostic system as they are operating inside Porsche's proprietary diagnostic systems, and they know Porsche will come down on them hard if they reproduce anything Porsche sees as protected intellectual property.  People have caught the rath of Porsche's lawyers for as little as reproducing a page for a vehicle's owners manual, and Durametric does not want to go there.  And like all diagnostic systems manufacturer's, they expect the use has a modicum of knowledge of industry standards and terminology, and access to service information for the vehicle.

 

BCM for example is an industry standard term, and means Body Control Module, and is a control system for non engine or driveline components such as lights, windows, security, door locks and access control, and various comfort controls.  Service resets are similar, with oil being obvious, while interim is for service items the come up between major or main service interval items (30K miles, 60K miles, etc.), and is again an industry standard term that applies to either your Macan or a Ford Fiesta.

Thanks for the info!

Needless to say, they can do a far better job of documentation. After all, they are selling these to the average DIYer.

I've had two Durametric products so far; the Enthusiast version and about two years ago, bought the Professional version.

Yeah its OK and it does some neat stuff, but Durametric seriously needs to produce a detailed manual and not the User Guide (dated 10-6-2019) that can be downloaded, which by the way, shows screen shots from versions that no longer exist.

Most folder names are self explanatory, but what does BCM Front, BCM Rear mean...for example. Maybe an acronym chart would come in handy.

Then Durametric's on-line video demonstration describing the Reset Service Reminders shows version 5.1.2.0 which does not even relate to today's 6.5.5.12 version. Yeah, I got it figured out but it still did not work. Instrument Cluster - Commands - Service Interval Reset - Oil, and "Send". It did its thing and I still get "Change Oil Now".

Also it would be great if they specified what the three options are...in detail:

Service Interval Reset - Oil

Service Interval Reset - Interim

Service Interval Reset - Main and Interim

I know what "Interim" means, but how does it apply to Porsche's maintenance? And what does Main refer to in Porsche's maintenance?

Pull the fuel pump relay, will accomplish the same thing.

I looked at both the Service and Parts Manuals.  All I could find for a location of the fuel pump relay is what appears to be in the driver's side fuse panel footwell area and it seems to be a single relay, instead of a dual relay as used in the 993.

Will look for it when the time comes to pull the car out of winter hibernation.

Thanks!

In the 993, I would simply pull the DME Relay. That cuts power to the fuel pump, etc. I could then crank my engine to pre-oil the motor after extended periods of storage.

How is that done on a 991?

Don't you just love these dipstick-less cars designed for millennials?

On my first oil change, I over-filled it by 1.25 liters all due to the fact I did not fully understand the Oil Measurement Display.

I thought the MAX level was at the top of the bar, which it isn't. The MAX level is shown in A below.

Anyway, I just drained it and the level is at MAX.

I also would not use a vacuum pump for the reasons mentioned.

Some tips on CCU repair that I came across...

CCU Repair

I don't believe it's either. Looks "grey" to me.

The pic was taken on a very sunny day which makes it look like a light grey...certainly closer to anthracite.

The only thing, according to the Porsche parts catalog, a 1995 993 only came with a black carpet. I'll have to check with my dealer one day. I want to match a CD changer cover to the carpet.

Would anyone know what color this carpet is; black or anthracite?

So that is what it is. I happen to have that technical bulletin on file as well.

I would guess there is one on the driver's door as well, because the one pictured above is on the passenger door.

I still don't know what the Digital Sound Processing System is all about or what it does. My 993 came with option 490; Hi-Fi Sound System.

Thanks.

I had the lower door trim panel off to install a new loudspeaker grill and noticed this connector not connected to anything. It is located just back from the door lock release lever.

Would anyone know what it is for?

That is great - please post it in the 993 section.

Thanks.

Done!

How-to DIY removed by author.

I came across this thread after performing a search for a procedure for mirror replacement on my 993. Its a good thing I wasn't in a rush...

Not that anyone said it could be used, note that this procedure cannot be used on the side mirrors of a 993.

I wrote up a short how-to for mirror replacement on a 993 which is held in place by a rotatable ring that locks the mirror in place.

993 Side Mirror Replacement

I and the local dealer who then called Porsche have been searching for the part numbers of the rubber plugs that seal up the 5 holes in the floor where the spare wheel is located. They admit to having had trouble finding the part numbers before, but so far they've come up empty.

Four of the holes are identical at 13.8 mm in diameter; the fifth hole is roughly 6 mm in diameter and is located under the cable tray towards the rear.

For now, I've used some non-metric plugs that I got at a local fasterner store; they don't fit all that well.
