Just sent my new to me 2018 Macan S with 49,5xx miles that we have owned for 2 months to the dealer for the Engine Control fault.

The problem started during stop-and-go traffic when the car was sputtering and trying to stall on taking off and the AWD fault and PSM faults came on. We stopped and restarted the car and the faults went away. Then when I got home and pulled into the garage, again the car sputtered and wanted to die. That's when the Engine Control fault occurred and never went away. We put a fresh full tank of gas into it with no change. Looking back, it frequently sputtered and wanted to die when taking off from a stop, not giving it gas at a low speed, or rolling into the garage.

The dealer has had the car for 3 days and says the issue is an O2 sensor and should have it fixed today. No mention of the PSM or AWD until I asked. Advisor said those faults were related to the Engine Control fault.

I am really concerned since the car is almost out of warranty. Thoughts?

 

My thought is to start reading some of the lengthy aftermarket warranty threads (some of which can only be purchased before the factory warranty expires).

Sorry about your car problem.

 

Well I took it to the dealer and they “said” my hose was damaged somehow which gave a engine code fault. Of course it was t covered under warranty so $1050 later code is cleared. Smh

 

What hose? Damaged...how?
Did you, or anyone, do work on your car especially near that hose?

Depending on your answers to the above questions, you may have a reason to complain to PCNA.

Hoses, sometimes, are defective & burst.

 

Anyone has seen a bad gas error code? Just returned from a long 4000+ m trip over the western US. Got “driving permitted” engine check light in Montana, then couple days later the engine light disappeared. Then the problem reappeared in Southern Utah and stayed with me all the way back home. Took the car to the dealer and he said it was bad gas (WP95). I always refilled at major stations like Exxon, Chevron, ConocoPhillips, etc.

 

Bad gas is a possibility.

 

Have a 3 week old Macan S with +/-1000 miles. Engine control fault lit up yesterday. Very disappointing, especially when I see these posts going back to 2015. So, let's go to the drop down menu and preview the anticipated dealer experience: 1st return......couldn't find anything, cleared the code, you should be good to go. 2nd return.....couldn't find anything, reflashed the ECU in "the abundance of caution", you should be good to go. 3rd return......it's an O2 sensor, and since Oxygen is produced by God, this is an Act of God, and not covered by your warranty.

I'd like to save myself from this tribal ritual. Any advice on how to unload this car ??? Or should I just sell my house and move near the dealer ??

 

I wouldn’t rush to offload the car. Nearly every new vehicle I got in the past 10 years had a minor issue in the first couple months, fixed and run issue free for the next 3 years of ownership. I am surprised sensors are not covered under warranty?

 

Well... apparently his new S has plus or minus 1000 miles on it. But seriously... is there any point to this thread? This is his first post?

 

I'm sure he'll update us on the progress and make it worthwhile

 

You’re the most unlucky car owner I have ever seen. Better just to walk or bike.

 

Super annoying for it to come on at just 1800 miles. Took it in and diagnosis was a faulty "leakage detection module" - emissions related. Took about 1.5 hours to replace. Hopefully this puts it to bed - anyone had a failure like this as such low miles?

 

Second day of ownership..........

hopefully, the car will sort itself out.

Hi did you get to the response and outcome needed? I have the same problem. I have booked in a diagnostics check, earliest is in March. Not sure I can wait for the issue to worsen.

 

Joining the club of the "Engine Control Fault - Driving Permitted"

43k miles, Macan S, driving performance is ok but I have a code:
P0456 EVAP System Leak Detected

Anyone knows how to fix it?

I'm looking around over here:

Got an unexpected gift from my brand new GTS

Just picked this bad boy up and on the way home engine cut power and check engine light came on. I honestly laughed out loud. I hope it’s nothing serious!

Cobb II power increases vs. leak potential question

I have a 2016 S that I enjoy immensely. It has only had the belt tensioner leak at 58K and Champion took care of that. Trying to keep it reliable, I have only done some exhaust work and minor upgrades on it. My question is that if I do a Cobb Stage 2 power Upgrade, will it cause undue stress...

www.macanforum.com

 

I have time today, so I popped the hood and behold! The throttle body hose is not all the way on. Let’s see if this does the trick…

 

Would you mind pointing out where on your picture the throttle body hose not being fully on is? Thanks.

 

Erased the code and did a drive around my neighborhood/ freeway. So far, the code hasn’t come back but Evap checks are conducted only a handful times per day.

Impressions after adjusting the hose + clamp:
• The engine is very responsive
• Boost is now reaching over 9 PSI

 

@dnimtzCO The code haven’t come back, so the hose was my problem.

 

In my case it has been the third time engine light, "driving permitted" in the last 20 k miles and it is again the same P017400 - mixture formation, bank 2 - too lean. gff states possible dme software issue. The service advisor told me he would elevate my problem to the regional manager.

 

Picked up my new Macan S on 1/22. After 5 weeks and 750 miles, got P0089 code, driving permitted. P0089 is "Fuel Pressure Regulator 1 Performance". Code repeats every time after I clear it. Comes on a few minutes idling after cold start. Did a search on this forum and rennline about P0089 with no results or posts.
Drove fine when I took it to the dealer the other day. A Porsche indy I know said it's probably just a sensitive fuel pressure sensor which can be programmed by the dealer to not be so sensitive. Also, my SA mentioned new Macans are due for a software update recently released by Porsche (Feb).
I should hear final results from the dealer in a few days.

 

Macan S, 2017, Engine Control Fault. Driving permitted.
What can be the problem? Any suggestions what to do?

I would recommend listening to the warning. It could be a lot of things. Take it to the dealer.

 

Will check with OBD II later. Maybe will be more clear about that fault.

 

Just checked with OBD II for the faults. It showing two fault codes below. Any suggestions whats can be wrong?
P0068 - Power train;
P0441- Evaporative emission control system incorrect purge flow;

 

On the P0441- Evaporative emission control system incorrect purge flow check that the gas fill cap is fully closed.

 

Gas fill cap is fully closed. What else can be?

 

Just had a similar code on my wife’s Ford Edge. On a Ford it’s not the cap there’s a part that controls the vacuum that’s not a big deal to fix. On a Porsche I have no clue. You could try googling the error code along with Porsche Macan. I had a Jeep that would throw a similar code. If it wasn’t the gas cap often filling the tank would kill the check engine light.

 

You didn't overfill the Macan did you?

If one overfills and contaminates the charcoal canister it can cause problems. I know of
a person who did this on a BMW and they had to replace the charcoal canister, etc.

Since that time, they are more careful not to top off their tank to excess.


Good luck!

funny that you ask. they couldn't do the diagnostic check the day i had my car there. so i waited 2 weeks on pins and needles. i figured to have my car back the same day or next day the latest. it turned out to be a sensor that had to be replaced. special ordered. took a day or 2 to come in. but the seals were not included. another day or 2. then the guy working on car went home sick. then they discovered another issue having to do with faulty brake fluid reading. it dragged on and on. i didn't hound them because, fortunately, they got me a loaner on day 2. in all, i didn't get my car back for 17 days. yup, from 1/11 to 1/27. but they fixed everything, checked everything, and it was covered by warranty.

Good to hear that the outcome was a positive one. I have mine booked in, hopefully it will get sorted.

 

I got this error too. Will put my fancy scanner on it tomorrow.

 

Please excuse me (and re-direct me) if this is not a similar issue or if this belongs on another discussion thread.

I have a 2020 Macan S with 16,000 miles. I have a pending order for a 2023 Macan S and will hopefully be getting it in Feb/March, at which time they will take my car as a trade. Today I was brining in the car for my NYS annual inspection. I didn't plan to have any other work done since the vehicle would be traded in shortly. On the way to the dealer, I got this message. "ENGINE OVER TEMP. PARK VEHICLE TO COOL DOWN". My car had been parked overnight in 30 degree temperature. The message came on within 5 min into my trip so the engine clearly was not overheated. I drove to the dealer which was 15 min away. I asked if they look at the diagnostics in doing the inspection and desrcibed the message. He said they don't. After the inspection, he said the message had not gone on when they pulled the car in and out of the garage, and he said it was ok to drive. He said to come back for a diagnostic check if the messaeg came back. Maybe it was the cold weather. Maybe it was a glitch in the diagnostic program. On the way home, it came back. I continued on and made it home ok. When I turned off the car in my driveway, instead of the engine (or fan) running for 30-60 seconds as it usually does, it continued to run. And run. It ran for 5 minutes when I called up the service department. It finally shut off during the call, which was a few minutes later. The thought is there is some kind of fan or temperature sensor issue. The first appointment I could get was Jan 10. He said it's safe to drive, but the fan may run longer than usual when I turn it off.

To say I am confused and concerned is an understatement. Hopefully, someone will explain this to me and re-assure me there is nothing to worry about.

Thanks.

 

What was the oil temp when error popped up?

 

not really sure but the car sat all night in the cold and was only driven for 5 min before message popped up. similar after the inspection.

 

It sounds like a temperature sensor issue reading your post.
