Update: my issue was very similar to OP's. It's at the dealer again. First time they repinned all the connectors but fault warning came and went a week after. This time they ordered a replacement air compressor. Said it's a bad check valve in the unit. I got the same crunching garbage disposal sounds for several seconds at start up along with random yellow suspension fault warnings come and go and then two mornings in a row, the front end raised all the way up and would not relevel until I pressed the ride height button off and on which created more crunching sounds until it leveled off. Car has 8500 miles.

 

Want to bring this thread back to life as my car has also just been brought in for the same "garbage disposal" sound coming from the front left.

Right when I unlocked the car first thing in the morning you could hear this crunching sound for like 5 seconds and then right as I start it up, noise stops and then the yellow suspension light came in.

Brought the car into the dealer this past Tuesday and still no diagnosis yet as to what is the cause, dealer is opening up a case with Porsche NA.

Car is a 2018 GTS with just a hair over 10k miles so strange for this to happen so soon into ownership. Hopefully all is covered by warranty and will do a follow up post once I get the car back.

 

Tell your service adviser to contact my service adviser, Ibrahim, at Porsche Grapevine in Texas.

 

that was exactly what i've been afraid off when configuring the car and after my SA even told me - get the steel springs, i did and it's zero troubles time.

It was + 35 C here today

 

Were your Suspension System Fault problem resolved & how many times did it take?

 

Were your Suspension System Fault problem resolved & how many times did it take?

There were a number of prior year posts on this topic.

With Porsche's history & records on this Macan A/S issue, why isn't there a speedy resolution to this issue in 2019?

Not sure where you're getting your "facts" from. Thus far few forum members have reported any problems with their AS.

Of course that does not help you, and you should not have to go back multiple times for the same issue, but please don't infer the Macan has widespread AS issues when it does not.

 

@novamchd1 This sux, whether you're "the one" out of 1000, or out of 10,000, who has won the unlucky lottery. Have you made any mods to your A/S (i.e. install of mechanical lowering links or electronic lowering module?) Or, is your suspension untouched/unchanged from original stock?

May not be possible to tell as his car is used.

 

Trully. I love to drive remote, curvy mountain roads.

 

Update: Problem was finally determined to be compressor pressure lower than specs. Replaced compressor, drained/refilled air suspension & re-calibrated steering & suspension. Driving great & no fault lights so far.

 

Of course a car with an air suspension system (even if it is from Porsche???) with a lot of control modules, electronics, compressor, sensors, pipes etc etc etc is going to have things thay may go wrong than one equipped with just 4 springs.....

Although I am still enjoying the A/S PASM, no glitches so far

 

Zero issues here so far with AS.

Finger tip control of height.......priceless !

 

OT posts have been moved to https://www.macanforum.com/forum/wheels-tires-suspension/54810-discussion-macan-suspensions.html

 

I find your posts very confusing, if not conflicting.

Here you indicate on July 19 the fault messages returned, and your car had been in the shop 6 times.

But yet on July 28 (9 days later) when you started the other thread “unfixable problem” in the Complaints section of the forum, you said your car was going back in for the 6th time, which conflicts with what you said above.

And there is much missing information to be filled in. You never answered if this is the same dealer you bought the car from nor explained any of the details regarding who you have complained to and the results, nor even identified the dealer..

You mentioned a week ago that your car was stuck in AS Low. What has happened since then?

Very confusing.

 

Haven't had any issues thus far - enjoying the macan turbo very much
*knock on wood

 

OK, so finally a problem with my Macan. The driver's rear side strut is getting about 1 inch lower than other wheel struts. I hear the compressor working extra to keep up. The suspension failure warning has come up intermittently.

Got it to the dealer and their diagnosis is a bad compressor. I asked: "how could it be the compressor? If it is the compressor, all wheel struts would be acting up (not only the driver's rear side)? Don't you think the problem is in the actual suspension strut?".

They insist that after consulting with Porsche, the problem is most likely the compressor, which cost $3,000 at the dealer + labor. I asked: "What if is not the compressor, would I just lose $3,000?"... no real good answer on this.

This doesn't give me a lot of confidence, and obviously getting a 2nd opinion.

I looked for the part in some websites, seems you can get these compressors for $750 (although may not be OEM).

I'm looking for some thoughts here, especially people that had gone through similar issues. Could it really be the compressor?

If Porsche AS is similar to Mercedes airmatic system then you have a leaky air shock. Your symptom is same as my GL550 shock failure and I have replaced all 4 air struts in Mercedes last 3-4 years. I would get a second opinion

Assuming out of warranty...? If so, find a good Indy shop to diagnose and quote. Should be at least about half the price... maybe 2/3’s max.

Figured I'd just add to this extensive thread instead of just making a new one. New problems include;

Air suspension failure

Driveshaft failure

Those of you with rock solid Macans owe me a beer, I really took one for the team with this car LOL

 

Hi guys I have a 17 Macan s the car was getting the front tires replaced. The garage jacked up the car without locking the suspension and then there was a pop I could hear air coming out. The car tried to leave out but all you could hear was air. Does this mean the suspension is f or is there a solution.

 

Was the entire vehicle raised on a lift or just the front end raised or perhaps one corner of the front lifted?

I heard a pop once when getting my Macan inspected, because the "technician" placed a floor jack beneath a jacking point with
the jack making all of its contact on one edge of the jacking point. The pop sound in that instance was the jacking point fracturing.

When I got home, I inspected the jacking point and discovered the issue. I went back to the "service" station and described the issue
to the "technician" who agreed to pay for a replacement jacking point (~$25 online). He volunteered to install it too! When the part
arrived, I installed it - I didn't want him doing anything more than a safety inspection on my Macan!

It was a pretty easy job to R&R the jacking point, FWIW

 

I would suggest you have your Porsche checked out by Porsche. As to who was at fault for not disabling the air suspension, was it a Porsche dealership or a 'car shop'? Can it be suggested you should have turned it off before hand? Should the shop have known? Did they realize the system had to be disabled before being jacked up?

Let us know what's found and who picks up the tab. GL!

 

It was a local garage, but now the car needs to be recovered and taken to porsche but I am dreading the result and the £££ to fix. But surely jacking the car can't pop the suspension??

 

Should they have known to disable the air system? Did they know how? This will be a tricky situation to find someone at fault to help pay for the bill that's coming.

 

To the OP's question, I'm not sure if jacking up the car should result in "popping" the suspension. I thought you locked it out to prevent it from running the compressor and trying to self level, etc. I'd be surprised if offloading the suspensions and maxing the travel would result in popping the air bags. It is just an air bladder isn't it?

I know I've jacked up one corner a few times and forgot to turn off the air suspension. No impact (knock on wood). I immediately put the wheel back down when I saw the other side starting to lift up / level the vehicle...

 

That's what I'm thinking, for example if you go off road and you have 1 wheel hanging off the ground due to the ground it shoudnt damage the suspension. But all I heard was a pop and hear air coming out, the car tried to rise again but nothing just air. But I was to scared to jack it up again to see what was happening.

 

Porsche Cayenne Prepping your Air Suspension Cayenne to Lift (955 GTS/S/Turbo 2010-2014) | Pelican Parts DIY Maintenance Article

Avoid costly damage to your air suspension by follow this procedure before lifting the vehicle.

A different system but a little clarification. Maybe I heard it starting to drop the air out of the lifted side and I immediately put it back down.

And this from the Cayenne forum:

Jacking up vehicle w/ air suspension

Wonder if anyone knows if jacking up one corner of Cayenne GTS without turning off air suspension would adversely affect vehicle somehow. I had nail in RR with slow leak. Tire shop I took it to used hand jack on that corner. After it was jacked up I noticed that wheel slowly drop another inch or...

Thx.

I'm trying to understand how raising the front end a few inches would have resulted in apparent damage to the AS (air suspension) system.

Did the shop jack the vehicle on the compressor? It's located beneath the floor on the left side of the Macan just ahead of the seat. There are
also air lines that run from the compressor to the front suspension units and air bags for the rear corners.

From the description above, it sounds as though one or more air lines has/have been severed and that occurred when the vehicle was raised.

Puzzling...

 

So it's seem that you are correct the idiots hit the air lines, however a temporary fix was made but the car is still saying suspension fault.

 

Hello everyone,

I am new here, but I would like to share some relevant information about this subject.
I did have the same issue on my 2015 Macan (61.000 Kms) and I have came across this topic while looking for more information.
Since information contained here helped me a lot, I believe it's fair to share my results.

As most of you, I had the yellow "Suspension system fault, adapted driving permitted" message and the suspension was dead.
After a while, the car was on it's nose, with is backside up. Basic physics. After repeated brakes, the weight of the front has pushed all the air in the back.
This ruled out any leaking air issues.

I have changed the fuse. Suspension worked briefly, leveled the car properly and then blew again and we were back where we started.
Having a good background in electronics, I have decided to do a test and change the relay. Mechanics said to change the air compressor.
However, the compressor was working since it leveled out the car.

Relay was 30 Euros/40 dollars, so I said it's worth a shot.

I am now some 40kms into this and it works properly. I will keep you updated and see how it works on the long term.
I do hear the air compressor coming on an off as it should (at stop lights, corners, etc).

TLDR:
If you have this issue and the car is nose down. Change the fuse in the trunk and see if it levels out your car after starting.
If it blows, change the relay. It's quick, easy and cheap.

 

It sucks as I was in the middle of a short/long trip. The car drove like there is no suspension at all, horrible.

Rear ends were lower while front end are normal when occurred. The question is that if this is a 'normal' known issue of a Macan? Mine is Yr18, Turbo., 18k on the clock. Drove mostly in sport mode with level down, load is around 600lb at the time.

Frustrated as it ruined the trip. Dealer fixed it for free in two days and said it is just a broken sensor. I thought it must a leaking air valve as I heard some air out from the bottom then the warning code showing on dash. The 2nd question is that am I supposed to use sport mode on regular base for the Turbo, if not, why would I went to a AS Turbo in the 1st place?

Not like the AS so far to be honest.

 

Dear friends
I just thought i would share this cold weather experience with you all. I have a recently purchased (6 months ago) a Macan S 56k miles and im the 3rd owner - pretty much full service history. Up to now no issues with this vehicle.
The last week or two its been unreasoningly cold in Aberdeen / Aberdeenshire. On one of these cold mornings i got the error message in yellow - Suspension system fault Adapted driving permitted.
Being new to Porsche I didn't feel confident to start tinkering around on my own, so called the local service centre - the service Manager was extremely helpful and suggested i drop it in for them to undertake a thorough check and rectify any issues that might have caused the error. He reminded me there would of cause be the minimum charge £180 per hour pro rata blah blah blah if it wasn't covered under the used car warranty.
On relaying this to my wife, she asked 'have you checked the fuses?'...hhhmmm why didnt i think of that!?! a quick google search showed that a 40amp fuse was in charge of the Air suspension system. the fuse box is located in the luggage compartment in the rear of the vehicle. After a quick check, it I noticed that the fuse was blown (probably due to the stress of trying to operate under extremely cold (frozen conditions)...maybe???)). I replaced the fuse (£2.60 from Halfords)..the warning indicator has gone off and the Air suspension is operating as normal...hate it when my wife is always right!!.
I will take some pleasure however in cancelling the service centre appointment tomorrow my wallet has also given a huge
sigh of relief!!
Thanks

 

Does anyone know how to "check the relay" as @mrobert_1366 suggests?

 

The relay is hidden under the side of steering column... if you start at the dead pedal and go up from there, you'll find it behind the lower dashboard trim to the left of the steering column.

You'll probably have to disassemble the trim...

This is the relay... but to me, the best way to test it is to buy a new one (they are cheap) and just replace it.

The fuse is in the trunk fuse carrier:
