The first troubleshooting step is to get the stored trouble-codes (DTCs) from the Transmission Control Computer (aka "TCU" or "Tiptronic Transmission Control Module"). PWIS and other Porsche capable scan-tools often list the TCU as a "Tiptronic", even though it is really a Dual-Clutch/DSG/PDK/S-Tronic transmission. The "Tiptronic" name is what Audi calls a conventional torque converter automatic transmission with electronic control and manual shifting features, and the scan-tools just used the wrong marketing name for it.

You could try pulling the Mechatronics out and just replacing the two "Circuit Boards", cheapest thing to try.
Audi B8/B8.5 S4 Quattro 3.0T Drivetrain DSG Transmission - 0B5398009F - Mechatronics Repair Kit 0B5398009F (0B5 398 009 F) (ecstuning.com)
Another forum member had issues only when the transmission warmed-up. It was fixed with new "circuit boards", which also contain the temperature sensor for the clutch fluid, and an RPM sensor.
There are many of these circuit board repair kits available on Ebay and Amazon. Some are much cheaper than the "real" VW/Audi kit, but they may work fine....

The next more expensive fix is to get a new or rebuilt Mechatronics unit (just the valve body part, not with a new TCU), and install the original TCU onto the new valve body. Then, no TCU programming is needed (to write the VIN into it (needed for the immobilizer).
But, you will need to run the full Mechatronics adaptations/calibration with your PIWIS.

Hello all. 2015 Macan Turbo P2737 pressure control solenoid F control circuit range performance. Has anyone successfully solved this exact code? Did you replace 1 solenoid? Did you replace the circuit board kit on the valve body? Did you replace the entire valve body?

I got this “no R-gear” message at mile 64 and less than 48 hrs of ownership of my new ‘24 S! This happened while driving down the highway and the car just seemed to disengage from the gear. The forward gears no longer engaged when I put it in drive, though I could still reverse.

Towed to the dealer, they were shocked and apologetic.. today they said they are going to replace the PDK control unit and recalibrate.. hopefully this is enough?!

Looks like I am joining the party too! I just had:

ABS/PSM loss possible to drive on
Gearbox loss Park vehicle safely

Codes are:
P150E00 Vehicle speed signal - implausible for ABS Control
011F03 Rear right speed sensor, sensor fault
P0700 Permanent Control System (MIL Request)
05228D Check DME fault memory content
U0159 Communication with Park/Assist
P2162 Vehicle Speed Sensor "A"/"B" Correlation


All are taken from a POR 2.0 computer.

Car is a 2015 Macan Turbo.

Transmission fluid filters and flush done <2,000 miles ago with OEM equipment. No slipping or issues have ever been present. Running a pedal commander with Sport -2 mode on.

I am looking for tips here and on Rennlist on what I should be ordering to fix the issue/s.

Hopefully this is all related to the wheel speed sensor, which I believe has a 10 year extended warranty: https://www.macanforum.com/threads/...s/just-received-my2014-2018-macan-wheel-speed-sensor-warranty-extension.177470/

Update, this was the exact issue! They would not honor my warranty with the car being built in April 2014. I bought the rear right sensor straight from Porsche Charleston and fitted it in 10 mins. No more issues. Thanks to this great community.

Woohoo! Thanks for the follow up - it may help someone else in the future.

I have a 2015 Certified Preowned (CPO) Porsche Macan S that I bought at my local Porsche dealership. I take care of the car and it is garaged on a daily basis with regular interval Mobil 1 fully synthetic oil. I really love the Porsche brand and how sporty and luxurious their vehicles are and would consider another Porsche in the future.

The problem that I have now is that the "Fault Of The Engine Control Unit. Gearbox fault possible no R-gear Possible to drive on." light came on and it is the second time this type of check engine light has come lit up. The first time I believe my local Porsche dealership mechanics might have done some repairs and updated the software

This time I seem to have Coolant sprayed or leaked all over the engine bay along with the light and this came out of nowhere. I have only driven my Macan for less then 15,000 miles in the 6 years of ownership and is surprised by the quality of the build. I really expected better for such a top tier luxury brand and at that price point.

My regular car warranty is expired and the Certified preowned warranty has expired. I believe there was an extension for the pandemic and that expired too. I have no clue where to start and would hope that Porsche can help with this situation. Thank you for any help as my car is sitting there and I am unable to drive it since it wont go pass 2nd or 3rd gear and there is no reverse. It is quite disheartening and I have driven other luxury brands such as Mercedes, Acura, Lexus and more without major issues such as this that rendered my car immobilized.

Thank you in advance for any help or guidance. I know that there are quite a few similar posts on the forum but I am just not sure who to trust to fix the issue other then Porsche. It would be nice if they provided some kind of recall fix or goodwill gesture. Would a coolant leak from a defective hose or valve or thermostat or water pump or radiator or T pipe cause the ecu on the engine to create a fail safe fault so it doesn't drive forward or let you reverse?

I've already tried contacting Porsche NA through the owner's inbox message and website email link and on X. No response at all maybe I should call them. I am in New York and if any recommendations on trustable repair shop it would be most kindly welcomed. Thanks for any advice and suggestions.

 

[reguy]

You mention this is the second time you got this type of fault message and your Porsche dealer dealt with it previously. If that was within 2 years (the first time they worked on it for that issue) you may or should be covered by the warranty on the repair.

 

[whiteporschemacans]

Thank you and I didn't know that. I will go when I had the ECU engine fault light serviced. I am just surprised by the quality of a Porsche and I really enjoy my Macan. Thanks again for your help and I will look into my service receipts.

Two common points of coolant loss are the expansion tank and the coolant pipe under the manifold. There are threads with some info in both of these here.

There’s also a thread about transmission issues. Without a code reader that can read Porsche specific codes, it’s hard to know what the problem is. Likely a problem with the mechatronic though.

Since you are out of warranty, I’d find a good independent Porsche shop to take a look at these things. If you can’t find that, an Audi shop should be able to help since the transmission is the same as the Audi 7-speed DSG. That said, many shops will not touch the internals of the transmission, so you may have to try a few.

 

[whiteporschemacans]

Thank you for the advice and suggestions. I will do more searching on the forum as recommended. I will try to scan the car later and see if I can provide some codes. I think I remember doing a search for recommended independant Porsche Shops maybe I can search for some Audi ones too since they share a good amount of components. I hope it is just a sensor that an be replaced and that will resolve the matter. Thanks again

I had this EXACT issue. Happened in January and it took me until two weeks ago to even accept that my car needed a new Mechatronic. Set me back $5K. My car is a 2016 and I've had nothing but problem after problem. I finally accepted that I had to dish out for a new Mechatronic. It's apparently a well-known/frequent problem with the 2015/2016 models. Porsche will usually blame drivers if service hasn't been done at the dealership. Highly recommend you take it to them if you've been servicing it through Porsche and let them explain it to you.

So frustrating. I finally treated myself to a "quality", German brand only to be tormented by problem after problem. Breaking my heart but finally decided to put her up for sale in the next week or so.

 

[whiteporschemacans]

Wow that is crazy and yes I agree with you I thought I finally treated myself to a "Quality" German car but didn't expect it would end up being problem after problem. That mechantronic part from what I googled seems to be around $1800 plus for just the part. I can't imagine how much Porsche charges for labor and the crazy part is I had this issue before but I am not sure what they replaced or repaired. I called Porsche NA they told me the dealership only warranty's the car repair parts for 2 years and that I am out of luck. I guess no point of dealing with the dealership for repairs or even purchasing a warranty. This is quite frustrating and unfortunate. Thank you so much for sharing your experience and I will research further and hope to find a qualified technician in NY to do the repairs.

 

[whiteporschemacans]

I was able to lift the plastic engine cover and have been searching around for cracks or loose connections and probably will need to look again. The coolant that I refilled is all gone again and I don't see a puddle on the floor and have no clue where the coolant is leaking or spraying towards. To me it feels like everytime the heater or air conditoner is on there might be a slow leak somewhere but then again this time it was just a complete dump.

I called Porsche NA and they said that the dealerships only covers the serviced parts that they installed for 2 years and it has been 3 years so that is no go on their warranty. I have only put 2000 miles on the car in those 3 years and is surprised how fast anything can break. The gearbox issue was resolved during that time under warranty but they only offered 2 years from then so I just lucked out. Porsche NA was friendly but could not offer me any assistance. I guess I am on my own which is unfortunate but very grateful for all the help and responses on this forum. From my receipt this is what they serviced 3 years ago

1) ALA2 Campaign - Reworking Service Cover of Fuel Pump
2) WLA0 Campaign - Reprogramming DME Control
3) 9A7-325-025-01 - Slide Valve Gearbox
4) 9A7-321-371-00 - Gasket
5) PAF-013-827 - Seal Ring
6) Lens-Head Screw 6x20
7) Cover Front Removed and Reinstalled
8) ATF Inspected and Added

For the Transmission I believe they did the PDK service but made me pay for the oil and filter

1) 37302551 - Transmission Electronics Control Unit Programmed
2) 38775500 - Transmission Control Mechanism Replaced
3) 37021999 - PDK Fluid and Filter Replaced
4) 7x Transmission Oil
5) Filter Element

I was able to scan the car with a basic Autel Dongle that connects to the OBD and the codes I got were

1) 00A046 - Instrument Cluster - Warning:Coolant Level
2) 84040E - Rear End Electronics - Roof Control Unit, Interior Lighting Faulty
3) 89010E - Rear End Electronics - Alarm Siren, Faulty
4) P174E00 - Transmission Control - Valve 3 in Gear Train Half 2 - Electrical Fault

My 2016 Macan S transmission was replaced twice due to "Gearbox Fault Possible No R" message and it would not move forward or even Reverse. Car done over 51k km in total. I never did any launch control but I drive in Sport Mode all the time. I just got the car back from the dealer after second gearbox replacement, transmission ECU and transmission fluid cooler replaced. Hopefully no further problem.
Just curious, do you guys drive in Sport mode all the time, if not most time. I always drive with Start-Stop switch Off.

 

[whiteporschemacans]

I drive in Sport Mode all the time and hope that doesn't cause a transmission to crap out like that. I don't use the start-stop option at all, I feel like it causes more wear on the engine. It still surprises me how expensive these repairs are and how they dont extend the warranty's on these transmission. Porsche NA wasn't able to help me and same with the dealership I bought my CPO macan from.

 

[Machan 0459]

My coolant reservoir was leaking and was from a minor crack at the hose connection. After a drive when engine at operating temperature, pop up the engine hood and I can see a spray of atomised coolant coming from the reservoir hose connection area. After Porsche change the reservoir, it leak again after few months.

 

[whiteporschemacans]

Check the Y Pipe all the down there with a flash light. I saw a big crack in the hose down there and that is quite possibly the usual issue with the coolant leak. If you are under warranty take it back to the dealership and show them pics of the cracked hoses. I feel that they dont usually do a thorough job inspecting like they should. There should be a work around that Y Pipe that other forum members have written up and there is also a Youtube video made by a popular DIYer on this forum also.
