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.

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...

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…

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

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

No problem, here:

@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.

 

[keskuk]

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.

 

[keskuk]

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

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.

 

[oqjnLu@>@W]

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!
