2011 Cayenne 3.0 TDI - Reduced Engine Power Under Full Throttle - Anyone Had This?

Hi all,
I’m hoping someone has come across this before.
I have a 2011 Porsche Cayenne 958 3.0 TDI V6 (245bhp) with around 127,000 miles.
The car drives perfectly most of the time, but if I floor it, for example accelerating hard onto a motorway slip road or overtaking, it will suddenly go into Reduced Engine Power and the coil/glow plug warning light comes on. The engine is then limited to around 2,000 rpm.
If I stop, switch the ignition off and restart it, the car drives perfectly again until I give it full throttle.
Other symptoms:
Slight hesitation/judder when crawling in traffic at low speed.
Occasionally the 2nd to 3rd gear change feels a little odd, but all other gear changes are fine.
No noticeable black or white smoke.
Starts first time every time.
No rough idle.
MAF unplugged gives the expected engine warning, but the full-throttle limp mode still seems to be a separate issue.
Generic OBD scanner isn’t showing an obvious engine fault that explains the limp mode.
So far I’ve been thinking along the lines of:
Boost leak.
Turbo outlet hose.
Intercooler hose or O-ring.
Turbo actuator/vacuum issue.
MAP sensor.
Has anyone had these exact symptoms on a 958 3.0 TDI? If so, what was the actual fix?
I’d really appreciate any advice before I start replacing parts.
Thanks in advance!

985 seats no longer heating?

Hi everyone, new comer here. 958 CTT owner with 14-way heated and ventilated front seats. I knew my drivers seat wasn’t heating anymore but recently discovered my passenger seat isn’t either. Is there a way to replace or repair the heating elements without replacing the whole seats?

Thanks 🙏🏻

Edit: I hate Rennlist. Looking for an alternative here.

Edit 2: I meant 958 not 985 in the title

Maryland Lemon Law

I am in negotiation with Porsche of North America on a ‘24 Cayenne S with electronic issues. After 7 attempts to fix it, Porsche has admitted it’s a lemon and now I am in negotiation for the buy back. I am in Maryland and the Usage Formula in the state law does not appear to have a defined usage cost formula for either the Mileage at First Repair attempt, or the Current Mileage. Most references I pull say it’s the Mileage at First Repair attempt, but Porsche’s consultant who manages their buy backs says no, it is Current Mileage. They also will not divulge the source of that calculation. Has anyone completed a Lemon Law Buy Back in Maryland where the formula for Usage was used? Location: Maryland

Need advice

I was thinking about getting a 2015 Porsche cayenne as my first car. I am in between base V6 or the diesel model.

I know that Porsches are a bit costly for the maintenance but I want to work on it myself, I have worked on my parents 2022 Silverado and I feel confident that I could work on it myself.

I just want to know what I should look out for when choosing one and what I should be prepared to replace from people that have owned the vehicle. Specially since they have some miles on them, around 80k-100k miles

Cayenne Coupe S vs GTS

I am going back to a Cayenne Coupe. I miss my old one. I will be using as a daily driver in Arizona. Occasional day trips around the state in the mountains and some overnight or weekend trips to Vegas/Palm Springs etc. I am curious what the difference is between the S and GTS. I am looking for handling and comfort but also love the HP. Or what about the hybrid? Please let me know your thoughts

Used 2015-2018 Cayenne

Considering a used 2015-2018 Cayenne and want input from owners before I commit.

Buying:

•	What to check on a PPI for this generation?  
•	Best trim/engine to prioritize   
•	Sweet spot mileage vs. red flag?  
•	Known issues for these years

Costs:

•	Rough annual maintenance costs?  
•	Big-ticket items around 60k-100k miles?  
•	Parts cost/availability vs. Lexus RX or Audi  
•	Worth an extended warranty, or self-insure?

Anything you wish you knew before buying?

Comparing against a Lexus RX 350 for reliability, but the Cayenne is tempting. Real experiences (good or bad) appreciated!

New to me 2014 Base

Just bought a 2014 Cayenne Base with 85k miles that is CPO. One prior owner, brand new brakes and tires all around, and a 2 year warranty. Paid $20k which was ~ $3,000 more than non-CPO, multi owner cars locally.

Looking at Mr12Volt for CarPlay.

Any other upgrades you’d recommend? I’d like to get a remote starter, but will wait til the CPO warranty expires.

Buying 2023 turbo cpo, pdcc vs no pdcc

I’m in NE and my daily is a 2019 TTS. I have a 22 base Cayenne that my parents pretty much use when they are here for 6 mo of the year. Will be selling the 19 TTS and want a 2023 Cayenne Turbo with 18 way seats; a must. The turbo isn’t a must, but there are just a few 2024 base with the 18 way at about $80k; will section 179 so turbo works better in that sense.

One turbo has a lot of cosmetics but comes with pdcc. Drove it. Liked it; missed the sound but solid. $116k, 30k miles. Cosmetic exhausts. Front ventilated seats.

https://finder.porsche.com/us/en-US/details/8OVLXM

There are two more, ones at $124k (not coupe), 9k miles and another at $105k, 30k miles. These have sports exhaust on them, night vision and full innodrive, 105k has bose, only front ventilated seats.

https://finder.porsche.com/us/en-US/details/9PV7PP

https://finder.porsche.com/us/en-US/details/36Q68M

There are quite a few more if I go out 200 miles but trying to keep options manageable.

I do drive aggressive and fast. Usually straight line, not a lot of corners so I feel like pdcc doesn’t matter that much?

Biggest reason for a suv is that I want the air suspension; will be driving to a lot of construction sites.

2021 Cayenne E-Hybrid

I have commented on a few posts but I'll make my own. I'm looking to buy a 2021 E-Hybrid. I am in love with the car. I test drove a 2022 at my local dealership but the low MPG (coming from a Nissan rogue lol) was a big turn off. The salesman asked about my driving habits but given my upcoming career change, I dont want to forgo the perfect car for me now. im happy to sell the car in a year if my situation changes. I would have to fly to look at and buy this car.

Am I crazy? I have this feeling it will be perfect but like.... i don’t know. this is my dream car.

I dont even want to link it on the off chance someone goes in before I can get there and buys it 😭 I test drove the 2022 and not even 24 hours later someone bought it. im happy to DM you the link if you won't buy it and can give good insight lol

Turbo GT on the Boat

Decided that I loved my original GTS so much (traded it in) that I wanted to go back to a Cayenne. Local dealer had a black on black Turbo GT on the boat already so I reserved it. Can't wait.

Currently on the SFL Conductor and is in the middle of the Atlantic.

Best leather steering wheel cleaner for a 2020 Porsche Cayenne?

Hey everyone,

I'm getting ready to clean and condition the leather steering wheel on my 2020 Cayenne and could use some advice please.

Has anyone used Leather Honey cleaner and conditioner on a Porsche? Did it keep the leather looking factory fresh, or did it make the wheel feel slick or shiny? 

If you've had great results with other products (Colourlock, Griot's Garage, Lexol, Koch Chemie, etc.), I'd appreciate your recommendations. I'm trying to maintain the original matte finish and avoid anything that makes the wheel sticky, glossy or slick.

Or should I just stick with the Porsche leather care products instead?

I'd love to hear what has worked best for you. Thanks!

Unsure of origin of tapping sound

Hi all, I am taking a look at a Porsche cayenne for a friend as he said this tapping sound had appeared only recently, looking into it I can comfortably say the sound is coming from the offside of the engine and is located roughly at the back of the engine in the location of the high pressure fuel pump.

I’m unsure whether the noise is originating from the pump itself or if the rocker valves or worn, I have used a diagnostic computer to check for codes and found cylinder misfires for cylinders 3, 4 and 5 as well as a fault for the EVAP emission control.

If anyone would have any ideas on what to possibly test or begin to replace it would be much appreciated, the car has been serviced recently by Porsche so I’m gonna hope and believe they changed the spark plugs 🤞.

Edit:
I realised I haven’t put any info on the car itself, it’s a 2019 3 litre petrol turbo with 51k miles on the clock. Owner has said the sound appeared roughly 2-3 weeks ago. There is no loss of power or noticeable changes to the attitude of the engine when driving however when idling it does sound relatively rough however I do not know what these engines sound like when idle normally

First Porsche!! 2023 Cayenne Platinum Edition

New to me! So happy to hear here.

Approx $53k USD with approx 19k km/12k miles

1 year of factory warranty left. Is it worth extending the warranty directly with the manufacturer?

I need some help...

2011 Porsche Cayenne Base (V6) \~170k miles. This is long I apologize

so this has happened three or four times before today but I am a little strapped for cash and I don't have anything else to drive and I can't just not drive in the area I live, it is not feasible.

the first three or four times, the following happened. I was getting ready to start driving (happened either on initial drive or after I was parked and started to move) and suddenly I get a warning for "Brake Force Distribution Failure." Car decides to not do anything, my gas pedal does nothing. I have to put it in park, turn off the car and turn it on again to get anything to work. However, after doing this once, it goes back to normal and continues to work without issue. Each of these events happened around a week or two apart give or take. Long enough for me to say its something that just happens

today it happened a total of five times. I was driving on the highway at around 80mph. Car suddenly (no obvious relation to acceleration) throws brake force error code as well as ABS Error, Generator Failure, and two other codes I can't recall. I have no acceleration when I press the gas pedal and my electronics are completely non-functional. Turn signals, hazards, etc do not work. Headlights are off. Internal lights in car sputtered on and off maybe a few times over the course of 10 seconds

I promptly pull over on the side of the highway and put the car in park. Turn it off and on again and attempt to accelerate back onto the highway. This time I am accelerating properly to get to speed and back on the road safely. I am driving for maybe 5 total seconds (some small distance but barely) and all this happens again and I pull back over. After this I am okay for the rest of that drive. I get to where I need to be and leave the car running for around 10 minutes maybe.

I get ready to leave and the car is fine however around 10 minutes in the same thing happens and I pull over. Again when I restart the car it goes maybe 15 feet and again dies with all the errors. I restart it one more time and it does not go anywhere and immediately throws the errors when I attempt to move (not sure if I just did not leave the car off long enough for whatever "system reset" to occur). I try to restart again and this time it runs normally and I can continue moving. The rest of the drive home the issue does not occur. When I get home I parked and left the car running for another 5 ish minutes and attempted to drive it again for a few minutes after to see if the issue would come up again, but it did not.

I have done some research and my suspicion as of now is that it is either the alternator or the voltage distributor not working properly. Someone help me out with confirming what is wrong so I can fix this issue.

Thank you <3

Question for 2024 turbo purchase

Hi guys!

992 - 911 s cabrio owner here, planning to drop my daily from a tesla model 3 perf to a cayenne as itching to get back to suv world and have a car to daily drive.

Found a 2024 still under warranty at 23k miles turbo pretty good spec’d for 125k all out with extended porsche warranty for 5 years and tax etc.

Massage seats, air susp, pasm, burmester, inno drive, surround view, sport chrono, matrix lights, head up display, panoramic roof

Not sure if its worth going over a used 2024 s at this point, and rather bump the 911 to turbo s at some point. I can still do both but do not want to spend more for cars this year lol

I have also considered getting a cybertruck, x5, range rover among some other options as well, but the new bmw looks horrible, and range gives older vibes. And cybertruck which i do love is useless to tow etc. due to range anxiety.

Thank you!!!

High temp while driving on the highway.

Back in march, I got the water pump replaced. The car been driven mostly within the city. Today, I took a long road trip and noticed that the temp would fluctuate.

If I drive anything above 80+, the temp would climb to around 250, then the AC compressor would shutdown and the temp drops back to 200. Compressor would kick back on and normal again for about 5 minutes. If I slow down to around 72, temp would be around 200.

I noticed oil temp been high too, it is running around 250 the whole time. The shutter is closed when I parked, but I noticed it does stay open once in a while.

My question is, do I bring it back to the shop and have them take a look? I’m 6 hours away from home, anything I can check?
