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!

I believe they did some work on the clutch and then the valve body. It's a known issue so they should be able to tell you right away.

Hi I'm Leyth new to the form, I got a pre owned 2015 Porsche Macan S with PDK Transmission 2 years ago with about 100,000Km on the dash.
All service history was available, and the car run fine with all the features.
I run into a leak in one of the radiator hoses, when took the car to my local garage, as its it not under warranty any more, and unfortunately we have one Porsche dealer in the country, which makes it a bit expensive to have them do the repairs.
The local garage which has experience with Porsches has noticed ware in the engine gaskets and other consumables items and advised me to change them, as I agreed, he also added that as I'm at about 130,000km on the dash it would be better to change the PDK Transmission Fluid.
I got all genuine Porsche parts including the PDK Fluid, he did all replacements and changed the PDK Fluid.
I got the car back drove it for about 150km and got a message saying to fill up the engine oil, so I did and spoke to the mechanic about it, and was asked to get the car back to him in couple of days, and just refill the oil as it requests it.
I kept the driving to a minimum, once I took the car to fill the engine oil I get engine lights "yellow" came on with these two faults both yellow:
1.) Transm. Fault poss. No R gear drive on poss. " 2nd, 3rd, 6th, R available"
2.) Fault engine control possible to drive on.
Meaning the car went into Limp Mode, as I turned the car off and on the fault magically disappeared, as soon as I was on my way to the garage turned the car off before the journey as I turned it on get the fault again.
Told the mechanic about the issue he said we will check it, got a call a couple of days later from him, saying the the leaks have been repaired, but nothing he could do about the Transmission as he doesn't have good knowledge in the PDK transmission.
So drove the car for a couple of days trying to figure out what could the issue be, so I noticed as the engine oil goes above 110c and I turn the car off and on the fault would disappear, whenever the temp is under 110c the fault presets. "I actually couldn't get the fault to go away anymore as the engine temps don't go above 100c now as the weather is starting to cool down".
Got an OBD reader, used it and got these error codes: p0778 which leads to a Pressure Control Solenoid, and P0700 which leads to a Transmission Control System Malfunction.

Note: the gears don't feel clunky or lagy and the changes are smooth, I don't feel any issues with the clutches.

I did some research on the error code and it could be 1 out of 5 things technically from a faulty senser to a faulty Transmission.
But I have a theory, after I did investigate with the mechanic I felt a hesitation in his voice when I asked if he recalibrated the transmission after the fluid change "I don't think he did it".
So my theory is if I recalibrate the PDK flush all the faults will the issue go away, or reset the PDK somehow so it can recalibrate.

Any ideas any one faced this issue or something similar.

Just purchased a '15 Macan S from Carmax. The car came with a 3 month warranty from Carmax, and with only 2 weeks remaining on the warranty I figured I'd take it to my local Porsche to do a full inspection to make sure the car was in good standing and to take advantage of the warranty in case anything were wrong. Up till this point the car has been driving just fine and even when taking it to the dealership it felt fine.

Got word back from my SA that my car was throwing the code P1765 and that they would need to do the valve body/mechatronics replacement, but this may not be a guaranteed fix. I did not have the error ever pop up on my dash that OP and many others have seen, but my SA told me it was only a matter of time I guess? Regardless, if this valve body replacement doesn't fix the issue then the car may need a new transmission all together. Carmax has since been notified of the error and is seeing if their local "specialty shop" can fix the issue rather than having Porsche do it. Regardless, at the very least the valve body replacement will be fixed, and whether by Carmax or Porsche I'm not sure. I asked them if this fix doesn't solve the issue and a new transmission is due, what then? They told me that is sort of a grey area and simply said "we'll cross that bridge if and when we get there".

So obviously my biggest concern is the valve body replacement not fixing the transmission issue, and a new transmission is due with no one willing to help. Not too fond on the idea of tackling a repair that will cost more than 2/3rd of the actual cost of the car. Anyone have any insight on if this worst case scenario were to happen?

Tbf I have not come across any PDK errors which have not been resolved by a mechatronics repair/replacement.

Some on here have said gearbox replacement but my guess is that was not the case and simply what dealer told them rather than explaining what the mechatronics unit is and does.

Just got an update from Carmax saying they're going to just replace the entire transmission with a rebuilt transmission that they're sourcing from who knows where. I guess the statement Porsche made about the mechatronics unit possibly not being a sure fire fix scared them enough to just want to replace the tranny which I guess isn't a bad thing, but still leaves a lot to be weary about. Waiting to hear back from them to see if there is any type of warranty on this repair as a part of me still doesn't feel entirely comfortable with them putting in a remanufactured transmission.

You adamant it's the transmission and not mechatronics unit, did they not replace mechatronics first to confirm?

I'm not adamant on it as they did not replace the mechatronics first to confirm anything. I think its more-so Carmax not entirely understanding the issue and wanting to just replace the whole thing rather than paying for one fix and possibly dealing with it not being fixed and having to pay more down the line since that was what was stated on the Porsche repair order (in the repair bill it said they would replace the mechatronics unit first, and then evaluate and also stated that this may not fix the issue).

No worries. I assume the new gearbox would also come with a mechatronics unit!?

Man I would sure hope so! Has there ever been a case where a transmission was rebuilt without a mechatronics unit?

Really not sure, I imagine there is a refurbishment that comes with and without mechatronics unit. Similar to how you get complete engine, long block or short block.

Being honest though, your issues definitely sound like mechatronics. And haven't really seen any failures of the PDK (DL501) which haven't been mechatronics or clutches (Highly tuned diesels).

@Drruddick I sent you a PM

Can you send me a PM? Having the same issue

 

[vanmacandriver]

My mechanic said it will feel like a new transmission and the car will need to learn my driving habits all over again.

I’m glad it all worked out. I was curious about this last part, are you suggesting that the PDK software learns the driver’s style and adjust shifting accordingly?

I own a 2015 Porsche Macan S. The car has always been maintained by my local Porsche dealer, has never been in an accident, and is in pristine condition. A month ago the engine light came on. Turns out there is a faulty transmission and the cost to repair it nearly exceeds the value of the car. My dealership has reached out to Porsche corporate, as have I, and it doesn't appear as if they will offer me any assistance due to the age of the vehicle. I was told that sometimes this "just happens." So basically they're telling me the shelf life of my Porsche is 5 years. This is my second Porsche and I thought I would always drive a Porsche. However, I would be a fool to purchase another one if they don't make this right. Does anyone know how I would sell this car? So disappointed right now. Any advice would be appreciated.

Kelly Blue Book, go to, get cash for my car, I was offered $23k for it not fixed.

I have a 2015 Macan S 68k miles, was told if replacing valve body, splitting the bill, $2,300 out of my pocket, does not fix, new trans $22k.

I love my car and the dealership, Rusnack Pasadena Porsche, has been very helpful. I ok’ed the repair today and I’m keeping my fingers crossed it fixes it.

 

[TeeJay]

Find an indy shop and look for a used tranny. I did that with a manual BMW. Got an additional 100,000 miles on the car spending about $1400.

 

[Don16]

Ye a few, you need a mechatronic or to rebuild your faulty one.

Rebuild kits for the DL501 gearbox will be perfect.

Most TCU's put into service in the last decade are adaptive to driver habits, this is nothing new or unique to Porsche.

This post just popped up on my 'must see'.
So how didi it go?
I presume a seriuos gearbox problem??
My 2017 had the intermidiate gearbox changed because of malfunction.
Luckely Porsche warenty, otherwise 16K€ without taxes nor placement...
