Truly amazing videos Jeff. I now have at least a basic understanding of how my 992 PDK transmission works and of the extraordinary engineering behind. Your contribution to the Porsche and mechanical engineering lovers community is fantastic.
Dear Jeff, fist of all, CONGRATULATIONS, all Videos are very well done and explained. While i came across your channel searching for the Boxster PDK sensor replacement, i have by now watched numerous of your Vids and am blown away by your expertise!.
Firstly Thank you Mr. Jeff for your amazing videos and guides. Secondly, I have a 991 Carrera 4S, changed the distance sensor and the car seems to skip 2nd gear or get stuck in it mostly on downshift. Attempted short cal and it always fails at 96% with error Synchronize position to neutral not possible. I am at a dead end.
Hi Jeff, I am in a dilemma after watching this, as I was just about to do a calibration to my 987.2 due to - hard knock felt immediately when manually downshift to 1st, then rpm spikes after, sometimes in 2nd,3rd also. On sport mode and higher revs only. another less annoying problem is the pdk response very slowly when cold, but much better warm.
@ thank you for your insightful response Jeff! from your experience, the short cal usually fix these problems temporarily right? I was thinking if calibration doesn’t help, what kind of problems would I be looking at for my symptoms?
@@dr.z8378 Honestly, a cal normally won't fix an issue. It's worth a try thought. If the fluid hasn't been changed, especially the clutch fluid I would definitely do this.
Have a look at this forum thread. It's the one I originally wrote on the virtual machine and explains all. www.planet-9.com/threads/piwis-2-setup-as-a-virtual-machine.238021/
Hi Master Jeff :) I'm looking for the 997.2 calibration without part replacement process. I have piwis 2 in simulation mode set to V. When I go Diagnostic [997] > Overview [PDK/Tiptronic] > Maintenance Repairs, 997 the calibration does not have any options, but if I start with 981 I have the same screen and options as you show. Is it just because I'm in simulation mode? Will it show up once I connect to the vehicle? (vehicle is not with me) Thanks
Hello, I replaced the gear position sensor because there was error P1732. After replacing the gear position sensor in the 718, everything works fine, but when I accelerate strongly, the gearbox error is displayed several times. After restarting the engine, the error went away. Now this problem no longer exists. Do I need to calibrate? Did PDK teach itself?
Thanks for providing this information! I enjoy to geek out on these topics but hope my 997 PDK never will have the problems. Question: My 50.000km 2010 997 with full dealer service history had a PDK service not long ago, but they did not change the pan/filter. When should that be changed?
I've dealt a lot with autos of many types over the years, and having changed filters I now don't. It's something I'm considering making a video on, as there is a lot of misunderstanding about the differences between an automatic trans filter and something like and engine oil filter. The trans filter, and the PDK is no different, will basically catch nothing as they use a very coarse media and are designed to only catch large pieces. All the small wear particles continue to circulate in the fluid, with the ferrous particles then being caught by the magnets in the pan. So the big ticket item is always the fluid. Change this regularly. It's easy and cheap compared to the pan/filter. An example. I'm currently rebuilding an old E36 BMW. It has 360,000 km. I dropped the trans pan and replaced the filter because I thought it might need it. When I cut open the filter I found 6 small pieces of metal in there, but otherwise it was completely clear. I counted them because I was so amazed at how empty it was. The oil was filthy with the dust like wear particles that come from the clutch disks and the magnets in the pan covered in ferrous gunge. But after 360,000 km the filter was basically clean. Long answer, but it needs some explanation. My advice to people is to not ever bother with the filter, but change the fluid as regularly as you can. I do it ever 10,000 km, which is over kill, but I do it myself, I have the time, and the cost is about $50 for the clutch fluid every two years which is peanuts.
that's a knowledgeable answer i agree mostly with so i just bought a new pan for nothing! 🫠😂😂 what about the diff fluid? change or no change? they brain washed bmw service advisors lol 🤷♂
My PDK seems to hesitate a bit from a stop, like a manual clutch that slips more than it should, then grabs. Think the short cal would remedy this? Otherwise, it’s smooth as silk.
Have you changed the fluid? I'd be doing this first. There are a lot of anti shudder compounds in DCT fluid that ensure good clutch take up, so good fluid is key to smooth operation, especially when there is deliberate slip like you describe. So I'd be doing this first and if no change then maybe do a short cal.
I bought it with 52k miles. According to the Porsche dealer paperwork, it had the 60k service done at 51k, including PDK fluid. I’m going to check the fluid level first, then a short cal. Cheers.
The PDK is made by ZF, but is licenced to Porsche only, so it's not fitted to any other car make. This is unlike pretty much any other ZF transmission, like their 8 speed autos, that used in many car types.
Hi! My question is irrelative to the topic but relative to pdk's.. Could the internal gear ratios on a pdk be changed? Thank you in advance and have a nice day!

There's no real harm in doing the 'cal without parts replacement'. The danger is doing the long cal and it failing, which it does easily.

Hello Mr. Jeff where did you get the piwis system? My selector lever sensor is showing a fault in my Macan after i did a pdk service.

Yes, it's because you are in sim mode.

It starts from 2nd gear right? Some people have reported that the Pedal Commander (?) tool eliminates the off the line hesitation.
@@WPI94 it does start in 2nd. I’ll look into the pedal commander, cheers!
Interesting Mr Jeff. So Porsche PDK is also a ZF transmission but tuned to Porsche spesification, right?
The PDK is made by ZF, but is licenced to Porsche only, so it's not fitted to any other car make. This is unlike pretty much any other ZF transmission, like their 8 speed autos, that used in many car types.
@@jeffrichardsoncardiy Oh i see. Thanks Mr. Jeff
Hi!
My question is irrelative to the topic but relative to pdk's..
Could the internal gear ratios on a pdk be changed?
Thank you in advance and have a nice day!
Not to my knowledge. I'm not sure anyone has attempted this.
