I’m glad it turned out well for you.
I had my PDK replaced awhile back. It was out of warranty, but Porsche covered it with a good will repair since the leak at the right half shaft was identified before my warranty expired.
Also of note, my extended warranty company refused to cover it since it was identified as a pre existing condition.

 

I got the same warning message and the dealer replaced the PDK valve body and all problems went away. See my prior post "PDK Problem and Repair" for full details and photo.

 

I got this warning coming home today from ocean city while stuck in bridge traffic. It came and went a couple of times, then came on for good a long with a check engine light that read as P2813 when I pulled the code. The car is still driving normally, but I’ll be taking it in to Porsche as soon as I can get an appointment. I’m on the Carmax warranty, so this should be covered.

i have had some clunkiness, for lack of a better word when I pull out gently from a stop. I’ve never known if it was normal pdk operation or not. Everything is smooth if I’m driving it like a Porsche, but pull out gently and it’s clunky in 1st and 2nd gear.

any thoughts?

 

That “clunk” sounds normal. Drive it like a Porsche is the way to go for PDK.

 

I’ve usually figured the clunk was normal since the dealer I’ll be taking it to did the Pdk service and should have driven it after. But lately I’ve been wondering and then todays message really made me wonder.

 

I had the same warning, transmission fault, may not have reverse. Also the clunk a couple times driving from a stop. It is not normal. Mine required some transmission work. My dealer and Porsche treated me great and I'm very happy with them.

 

hey bud im going through exactly the same symptoms and have an appt scheduled for this week…if you could let me know how they fixed you up i would love to be able to tell them exactly how yours was fixed…much appreciation in advance!

 

What work did they need to do?

 

@Drruddick I sent you a PM

 

Having the same problem right now. Can you PM me what they did also? TIA

 

So I got my Macan back tonight. I dropped it off two weeks and one day ago, their first appointment slot and the process was a little protracted. The fault codes were of course gone by the time I dropped it off, but they were able to read p179c00 a main pressure valve electrical fault. This required consultation with Porsche technical to decide if I just needed the valve control unit, or a whole gearbox. The answer ended coming up as the valve control unit.
Oh, and I needed a new transfer case. The slight clunk was the transfer case.
Luckily, we’ll not really as I bought the car at Carmax in order to get the warranty, I had the Maxcare warranty. This is where the protracted part came in as they had to send an adjuster out twice before they would approve about $7000 in repairs. They did, and this whole thing cost me $150, plus the $2500 I spent on the warranty. Though I’ve still got 24,000 miles to get more value out of that...

at any rate, the car is very smooth now, if I had only known that the previous condition wasn’t right..

and Porsche of Annapolis and my SA treated me very well and were patient and helpful in dealing with the 3rd party warranty.

 

The real treat is that extended warranty goes on. Next up, timing case cover bolt failure. Who paid for the transfer case? Was that also the extended warranty?

 

The extended warranty covered the case and the valve body. I paid the $150 deductible on a ~$7000 repair, it just took longer because of the approval process.

 

@Davidle86 Sent you a message.

 

So this happened last night. Cars always know when there’s a lil more cash than normal around me. CPO to the rescue !

 

Can’t read the warning. What is it saying?

 

Sorry, that’s the gearbox fault message. Poss. No R gear. I also didn’t have 2,4 or 6th gear. Dropped at the dealer and awaiting word on how long they’ll have it.

 

That did happen to me last year! I have managed to arrive at my destination (work) safely, came back after 8 hours and the error was gone. I took it to the dealer the next day and they did diagnostics for a week and found nothing. I didn’t get that error again after that, it might be a glitch in the software!

 

I have a 2017 Macan GTS with 36,000 miles, regularly serviced at local Porsche dealer and have had no issues with anything until last week. While driving to work last Wednesday, two warning messages appeared. First said "Transm. Fault, Poss no R gear, Drive on possible". Second message said "Engine control fault, Consult dealer, Driving permitted". Macan started shifting erratically and would only shift in 2nd, 4th and 6th gears. I drove to work at 50 mph and called dealer and they told me to drop it off on way home.


I dropped the Macan off after work and the dealer put me in a brand new 2019 Macan base loaner. The next day the dealer informed me that one of the solenoids on the transmission valve body (also called mechatronic unit) was stuck in the 5th gear position and it caused the erratic transmission behavior and the warning messages. The dealer was waiting for the mechanics diagnostic report and warranty approval. Porsche authorized a new PDK transmission valve body which has electrical and hydraulic components built into it. (photo attached, weighs 35 lbs. per my mechanic) My advisor told me the part alone is $900 plus 3-4 hours of labor.


The dealer called me Friday at noon and said that my Macan was ready! The dealer had these parts in stock, which may indicate this is more of a common issue. Repair also included new PDK fluid which normally gets replaced at 40,000 mile service.
Luckily I was under warranty and did not cost me anything. So far the Macan is riding fine. My mechanic said it will feel like a new transmission and the car will need to learn my driving habits all over again. Shifting is super smooth. Hope this is the end of this issue, scared the heck out of me.


BTW, I was very impressed with the Macan base loaner with 18" wheels. The new PCM screen is nice but noticed the font and touchscreen icons were small and wasn't so user-friendly. Not sure if these can be adjusted...

Just picked my car up. The issue was exactly as 997TTurbo experienced except. The only exception was I lost all even gears. All is well and I'm back rolling.

 

I have a 4 year old Macan and love it, never had a problem until recently. I've always brought it to the dealer for service, and was never late nor missed a service date. About 6 months ago had the usual service and fluids were changed, including transmission fluid. Then several weeks ago an error message showed up stating "Transmission fault Poss. no R gear Drive on poss." I brought it to the dealer and found out that the wrong fluid had been added to the transmission by error, 6 months prior. The dealer took the car back to pull the engine,replace all gaskets, and change the fluid. How will this affect the life span of the current engine and transmission? It's no longer under warranty but I'm afraid this is the death dance of a car that was previously in perfect shape. What should I ask the dealer and or Porsche to do?

 

Definitely keep all your service records and especially have documentation regarding the transmission being filled with the wrong fluid.

Personally, I would ask the servicing dealer to provide an extended warranty for your vehicle. I would first ask them nicely and explain to them that you have serious concerns about the long term implications of their mistake.

If they are not receptive or not willing to extend any form of good will to you I’d write the GM and Service Manager a letter expressing the same.

Next step if they’re not willing to help is to contact PCNA.

Final step lawyer up.

IMO - they really do owe you piece of mind that you are covered incase something goes wrong in the future related to their error.

 

What transmission fluid wad changed? Was it the PDK fluid? They are 2 different types of fluid.

How could the dealer make such a glaring mistake? Could it be something else?

 

Correct it was human error at the dealer. I understand that there are two types of fluid and the wrong fluid was put into the wrong area. I have no idea how Porsche designed the refill ports, but evidently, someone got confused. I wonder if they are next to one another and look similar? My long term concern is what kind of wear and tear has already taken place? Is the engine or transmission trashed? This is not my area of expertise. I love the car, it's awesome, but I still expect it to last for a long long time. What am I looking at long term?

 

Hi folks,

This just happened to me this morning...

There are now 2 faults displayed:

The first one "Possible R gear fault, driving permitted".
Then followed by a second one "Engine Control fault, consult a workshop. Driving permitted".

There were obvious symptoms before this happened but not sure if it is related:

1. When driving in heavy traffic and the gear selector on "D" and gears change from 1,2,3 cycle I'd hear an occassional thunk/clunking noise in the underbelly.
2. Same thunking/clunking noise occassionally when going on reverse but noise is more prominent and obvious on symptom #1
3. I've noticed in Sport mode, there are occasional times when it would hold a gear too long before it upshifts. Granted the RPM's are normally at 2K at a minimum in sport mode but sometimes holds the gear at 4-5k in Sport mode on non-spirited driving.

I dont want to speculate but is symptom #2 the dreaded transfer case issue I kept reading about in the forum?

Not sure how to move forward from this point and would appreciate some sincere advise from folks here who would take this kinda thing seriously.

I'm at 55K and was just out of warranty.

 

...Second error...

 

1. Probably the main cause/symptom.
2. TC problem shouldn’t trigger error messages.
3. Seems normal. My Macan S does that once a a while.

 

Same here. 2015 Macan S. On Friday, all three faults came on. Car was lurching and making all kinds of bad sounds apparent (via wife report). Car not in warranty and towed to dealer this morning. Mentally prepared for the worst. Will report back.

 

Good luck Drew, let us know what the dealer said.

Its odd that in some of the googling search I found, others waited for "a few hours..." or so and the issue went away seemingly permanently. I'm still curious to find out what the error code might be for this issue and how this issue is normally resolved.

 

So after leaving the car parked and untouched for a day, I started it this morning and the error went away, just like what others said who had the same issue.

I started to drive to the dealer to have them diagnose this issue, after driving about 8 miles, the error messages came back. I parked and called a tow truck

After waiting for about 20 mins for the tow truck, I figured I’d start the car to see if the error is still there so I started the car and again the error went away....so (shrug).

Is this issue more software related than mechanical?
