Oh and also a shout out to Santirx for another great video.

 

Thank you @Santirx for this excellent DIY video. I was able to complete the PDK 3 stage calibration per your instructions perfectly.

I also did the Transfer case Integrator reset and Angle teach. My pre and post Val’s showed less than 1 degree of change after calibration. I would assume my Tx case clutch is in good shape.
Cheers !

 

One thing I’d like to add is that PDK fluid needs to be 107 degrees Fahrenheit for clutch bite calibration

 

It is required that the transmission fluid temperature be between 40 to 60C.

It is a pre-condition of the procedure. If not met, PIWIS won’t allow you to perform it.

 

I was having a serious clunk going into and out of first gear, really noticed it coming off interstate ramps and low speed city driving. Putting into sport mode helped. I checked PDK fluid first, no problem there. Next I did the PDK calibration.
It takes awhile to get to 40C with your wheels off the ground! I completely missed the temperature ranges.
It was the first time I have used PIWIS. You‘re on a timeframe, I got timed out a few times. Could be old man disease.
Keep the videos coming! You’re doing an excellent job!

Did the clutch bite calibration solve the issue?

 

I don’t know yet, I’ve still got to reassemble where I checked PDK fluid, gotta do a check on everything while she’s still on the safe jacks. Also want to change oil, clean inside my wheels, check pads and rotors, clean. I’ll have her ready for a Sunday drive

 

Success! I ran the oil reset and clutch angles on the transfer case, no more clunks. Thanks so much for your inputs!
Here are pre and post vals. I don’t what it all means except that each time I change fluids in the PDK and transfer case I’m using PIWIS.

 

Very well. Thanks for your confirmation.

 

Nonsense....you need to run the Cal after a fluid change.

PDK Clutch Calibration - 2015 Porsche Macan S

I’ll be performing a periodic calibration of the PDK going forward. It is required that PDK fluid is changed for calibration. Hence, I’ll be performing this PDK clutch calibration after a fluid change. Although I’ll be performing a full calibration, only a clutch bite point recalibration / adaptation is recommended.

The clutch bite adaptation adjust clutch plates for any wear that might had occur in between oil changes.

A full PDK Calibration includes (1) calibration of the selector level position and transmission range sensor; (2) calibration of the distance sensors and (3) adaptation of the clutch bite points.

This video document my experience with the calibration process.

Thanks for the great video! Very helpful!

 

Has any tried the clutch bite calibration again with launch x431? I got the first 2 procedures done but not the clutch bite maybe I have to warm up more?

 

These are the temps I’m attempting to calibrate with using Launch x431

 

Also I did the Transfer case fluid and i didn't see where Launch allows an "Angle relearn" I was able to reset the wear integrator but no luck finding the other.

Also still no luck on the PDK clutch Bite Adaption on X431.... any ideas @Santirx ? Thanks for the videos ,I've used them a ton.

 

T003 is the internal temperature of the electronics of the transmission control computer.
T004 is the temperature of the PDK clutch/mechatronics fluid. This is the one that is important for the Calibration/adaptation routine.
T005 is the temperature of the gear-oil, in the gearbox section of the PDK transmission. This temperature sensor is only present in V6 engine equipped Macans.

Where did you find the reset for the Transfer Case Wear Integrator? I could not find it my X431 Launch. What is the POR software version in your X431?

 

That’s a good video, thanks.
Did you record the bite points before and after to calculate clutch wear?

Curious; are you not concerned Porsche may come after you for use of the software?

 

I haven’t seen the before and after yet.

 

Thinking about just bringing the car to the dealer to do the TC and PDK software calibration.. seems like it's not clear which scanners can do it?

 

I changed my fluid a month ago and the tranny is shifting fine, but doing a PDK recalibration has been on my mind. Is there anyone here on the forum living in the Westchester NY/CT area that has PIWIS willing to trade lunch for a recalibration?

 

Has anyone found if the x431 can do the pdk re-calibration?

 

Do you guys think calibration might fix the slight body shake I feel when going from 1 to 2 from a stop? Almost like a stick shift when someone is not totally familiar with the clutch. All the driveline fluids have been changed.

 

Is that that around 1500RPM? I get that too and I think it's because the car doesn't downshift to 1st until you are at a complete stop so that trying to accelerate in 2nd is not ideal for the pdk. Mine does a little stumble too.

 

I guess to me, it feels just like when I got mildly experienced with stick but didn't nail down the perfect smoothness of the first clutch bite in first when you're going off from a red light.

 

Interesting feedback I got from a Porscshe indy:

Hi XZY, yes we can reset the calibrations but it's not recommended for every car. By resetting it, you will be going back to factory values. But do not forget that your transmission and transfer case are not brand new. Wear from thousands of miles might cause clearance issues, and you might experience clunky and hardy shifting transmission. Just giving you a heads up. We need the car here for a couple of hours. We charge $240 for the calibration reset.

 

I don't agree with the above statement. The calibration is done to compensate for any wear or changes in operating parameters of the clutches, valves......

 

Yeah, and at $240, I might as well just buy the right scanner that can do the reset itself. I also have a 718 GTS so I imagine it'll be useful for that vehicle as well.

...now if only I knew the least expensive scanner that can do a PDK and TC reset calibration.

 

I agree with @VAGfan. The process compares values and adjust. For example, this is the wording on the clutch bite adaptation:

During adaptation of the clutch friction points, the learning values of clutch adaptation are reset and the clutch pressure required to close the clutch enough so that it just begins to transfer torque are taught.

So, it compensates for any wear.

 

Just a heads up to everyone, this is on sale for $380: https://www.amazon.com/dp/B08ML7T7KZ
That is the Maxicheck MX808S, which according to autel's site: Vehicle Coverage | AUTEL

Can do:

Transmission control

/

Special function

Calibrate

AWD

/

Special function

Transfer box oil service

So I think this might be the best option. Ordered it and will give it a try.

I think this might be the Otofix equivalent: Limited-time deal: OTOFIX D1 Lite 2024 Bidirectional Scan Tool, Bluetooth OBD2 Scanner Diagnostic Tool, 2 Years Free Update, 38+ Services, CANFD & DoIP Protocols, All System Diagnoses, ABS Bleeding, Auto VIN https://a.co/d/jaHkfxB

This OTOFIX D1 Lite car diagnostic scanner can clear your trouble. Functions as MaxiSys MS9XX and MP8XX, OTOFIX D1 Lite obd2 scanner diagnostic tool allocates 38+ maintenance functions for 99% of vehicles and 99% of vehicle common problems.

Including Oil Reset / Injector Coding / Throttle Reset / DPF Reset / SCR Reset / Gear Learning / Clutch Learning / IMMO / Suspension / ABS Bleeding / EPB Reset / SAS Reset / WIN DR ROOF / Seats / Lang Change / Limit / ABSSRS / CHG Tire Size / BMS Reset / Headlamp / Airbag Reset / Turbo, Cylinder / A/F Setting / TPMS Reset / ODO Reset / etc.

 

Actually the Otofix I referenced above is equivalent to Autel Maxisys which is a $700 to $1000 scanner.

 

According to their website function lists for special functions, seems just about identical between the D1 Lite and MX808S. I think the only difference is the quality of the hardware/case, CPU, and RAM.
