Have bought a new car Macan, and I heard a friend say to brush some Porsche hidden functions, using the Porsche engineers version of the computer brush out, which a friend can help me brush out, computer engineer, who can brush out, please contact me, and I will thank you to the way you like.

All of those links you posted are for scanners, I am looking for a device to do coding of features not a scanner...
And more specifically, I certainly see posts with coding devices, but I am looking for what is the cheapest way to go about it, I don't really want to spend $700 on such device just for a couple of simple changes.

The CTEK is okay to hold the car up if you are gonna connect quick and make a quick change.
If you are going on a "Session" it will not hold the car up. The Car needs a DC power supply. You can read about that, build your own.

For instance, recently I was curious what the car was actually pulling, on +"VE" lead when coding, and connected to a 65A DC supply, the value via a KLEIN DC current clamp was 19.5A DC. The CTEK can push 5.0A DC, MAX. so, Ctek cannot keep up with this. Never code with low battery voltage.

My Ctek has a "supply" setting where it delivers maximum voltage continuously. I imagine that would keep up as well as the would with the car running and alternator supplying the voltage. Additionally there are many types of CTEKs so the assumption of pushing 5A may or may not be correct

If I understand what you did, you connected a 65A (max capability) battery charger to your Macan, and turned ON the ignition, with the engine OFF, like you would during coding. And you then measured the current from the charger, with your clamp-on meter on the charger wire, and observed 19.4 Amps.

If this is what you did, your conclusion that you need to supply at least 19.5 Amps during coding is not correct. Depending on the charger output voltage, it was supplying more amps to charge the car battery than what is required during an "ignition ON, engine OFF" scenario. To measure how much current you need to supply during a coding session (ignition ON, engine OFF), just put your clamp-on ammeter on the pos or neg cable at the battery. No external charger or power supply should be connected.

Assuming that the radio, and the HVAC blower are off, and all lights are off, the ignition ON/engine off "idle" current is probably between 3 to 8 amps (my guess).

You understood the set up correctly.
No where did I state that "you need to supply at least 19.5 Amps during coding", or conclude anything, you wrote that.

This was my observation of the +ve power supply lead of the DC supply....you can clearly see the RED lead.
I will throw the clamp around the battery +ve lead next time, of the car, same state, we will see.

I'd be interested in this info too if you do this in the future. 19A seems high but you have put more work into it than I have so I can't criticize.

LOL...you concluded "so, Ctek cannot keep up with this."

To add some value-added to this thread, please repeat your measurement at the battery, without a charger/power supply connected........then we can make an informed decision as to how much current a charger ("power supply") needs to provide during extended coding sessions. The Porsche worshop manual specifies something like a 95A charger ("power supply")...that is ridiculous.

Correct.......CTEK MAx is 5A...at least my version...and the most popular one used on here.

You agree right....a CTEK could not push 19A ??? Which is what the car was "consuming" from the DC supply.

I agree the Ctek Max can not push that amperage but some Cteks can. Makeadeel did not mention which version he had. I wouldn't stress about coding if using my CTEK's supply mode. I have the CTEK Multi 7002

Teddis, I do understand your point and it is correct, no one should code when their battery is low. Going through all the menus is time consuming and a battery can get drained pretty quickly. Last thing you want to do is get hung up in the middle of a code and brick your car.
 
#902 ·
Another question, I always put my CTEK on the actual battery but it looks like Teddis has it on the jumpers under the hood. Is one or the other a better place or does it not matter at all? Under the hood sure would be easier. Not having to take the spare tire out and all

It is the CTEK MXS 5, and I also used the CTEK LiPo version when I was doing a lot of ESys coding on my M cars in the past with no ill effects.

I am sure it could be a heavy draw if testing / cycling various engine and transmission components, but I suspect most folks here use something like a CTEK when coding, and are probably taking about 15 minutes to do so.

I have an OBDLink dongle and the Torque Pro app.
I scan for codes and it comes up with 0 codes. This seems a little hard to believe so I am wondering if you need a Porsche specific code read to just read codes?

The iCarSoft site has way way too many model, I am just looking for something simple to read out all the codes in my car? Preferable just a simple dongle to my phone.

I have spend the last hour reading through posts on here and there's mention of iCarsoft, Autel MD808 and Launch X431. I had an iCarsoft and frankly it seems pretty overpriced for what it was...

Do you really need a Porsche specific tool to read all the codes?

Has anyone had any luck using the PIWIS III clone From Autonumen?

Can I plug the Piwis3 Diagnostic Tool Piwis III V41.800.022+V38.250 Software with Lenovo Yoga12 I5 8G 5300U Laptop into my Macan and immediately use the tester with the Lenovo Laptop?

Do I have to set the computer date? Does the software expire or do I need to pay more as time goes on?
Do I need to buy any additional software or modules?

Help would be greatly appreciated as I am looking for a tool that will measure the oil level for when I do my own oil changes, thank you!!
