I can vouch for the durametric, which I just used two days ago for the same purpose.

 

Durametric is really the only decent solution.

I think there are some solutions that will do the basic reset check engine indicator (I haven't tried any of them, and I've never got a straight answer on if they really work on my 991, thus I went for Durametric).

 

If you don't get faulty codes is there any other way with durametric to check for abnormal values?

 

Should be able to use a general OBD2 code reader/data viewer to read codes, and view (and possibly log) various OBD2 data, like intake air temperature, coolant temperature, spark advance, throttle opening, load, O2 sensor voltages, and a few other things.

What you can't view/log are things like camshaft timing values.

 

Using OBD2? I don't think they work on 991

 

Manufacturers are required to provide standard OBD2 codes on all cars after a certain date (2000?). They are allowed to have extra codes, but they must meet the minimum generic code set that all OBD2 readers can read.

 

I just wanna say that I like your post and its very interesting one.

 

Yeah the OBD codes are mandated mainly for engine, emissions and transmission related items. exactly what information is present differs between OEMs, models and model years.

So when you buy a generic OBD-II code scanner you generally get the basic stuff that comes out of the DME (Digital Motor Electronics). If you are lucky you can reset the check engine light.

However much of the information in newer model cars (such as the 991) have many ECU's (Electronic control units) that are on the same OBD CAN bus. Porsche has about 20 or 30 ECU's, of which the Airbags are just one. Things like the dash gauges, PCM, Doors, parking sensors etc.

In general to get information more specific to the make/model, for say a Porsche you need something that knows the details of that particular car and unless it is a standard OBD2 ISO command that is unlikely.

The Porsche PIWIS is the official tool to do all this, but like most Porsche diagnostic and info it is priced out of the range that mortals could afford. This is the tool that is used to "code" by the dealer (i.e reconfigure car when optional equipment is added or removed).

For a 991 your options are fairly limited and the only thing out there that comes close is the Durametric. Yep you have to spend $300 bucks on it, but it beats having to go to the dealer especially if you like to work on your own car. That said, you can get at a lot of interesting information with it and to the curious you can learn a lot about how the car works.

 

I am looking for advise on replacing the stock suspension on the 11 Panamera 4S. I have now confirmed that I have springs and structs and not air bags. Can anyone tell me if they have replaced theirs and if you are experiencing any issues with the tire wear on the inside of the tires. I am asking because I've experienced similar issues with my Range Rover and M5. I want to know if there is some type of camber kit I can get for the Panamera to try an eliminate that issue. Also can anyone recommend what type of lowering kit I should consider. Please advise. Thank you

 

Probably have better luck finding someone who has installed a kit in their Panamera by posting this in the Panamera forum.

My general advice would be to check with the company that offers the suspension kit you are thinking of using and see what it recommends you install or need to add to the kit in order to get the suspension/alignment settings correct to avoid excessive/uneven tire wear.

Often times when a car is lowered the stock alignment adjustment range is not enough to bring the car into the best or optimum alignment and camber/caster hardware has to be installed in order to give the tech more adjustment. But the company offering the kit should have some info in this.
