I lowered my Macan by 20mm. Did it myself, with no issues. The dealer probably tried to readjust your car without zeroing back to default first. I adjusted my car several times and found it most effective if every time I adjusted back to default height, then do my adjustments from there.

How did you lower it? Do you have a pwis 2?

Not sure how lowering links would resolve the OP's problem. I don't think I understand.
Too much helium
... or too little helium ... the margin of error increases at the extremes of any gauge. It has been argued that these gauges are electronic, so the margin of error is gone (which is correct), but the extremes in the physical geometry is introduced because the vertical measurement is based on the top and bottom of the rotation of the circular sensor.

I had mine lowered this way. what no one is talking about how much it throws the alignment off. I had my local shop add adjustable control arms to fix the issue and not eat my rubber up.

At least several of us have had our Macans significantly lowered for several years with no unusual tire wear. Of course I'm not claiming if you lowered your car like the photo in post #21 there would not be an issue :)

This must have been someone too stupid to follow simple Piwis instructions. Lowering a Macan or 958 Cayenne is fairly easy, done it several times.

This is an example of -32mm on a GTS (left) and S (Right) each compared to stock ride height. Left with 15mm spacers front and rear, right got its 15mm spacers shortly after that pic was taken on the front as well.

So with all the problems that have been reported with trying to get dealers to correctly lower our Macans with PIWIS, this is proof positive that there are plenty of stupid techs at Porsche dealers? No one is saying it’s not possible to get it done, but many of us have had difficulty. Best thing to do is to just install a module, instead of having to return to the dealer every time you want your height adjusted.

Well, first of all, OEM Porsche dealers are not allowed to lower your Macan. They are only allowed to adjust to stock height from factory point of view.

Secondly, I know some dealers try to help customers by adjusting to slightly lower ride heights, within a small range of less than 10mm. So I'm not sure how anyone could face serious issues here w/ an OEM Porsche shop, per definition they should not lower any Macans... if they do nevertheless and face issues.. well...better change the shop..

Independent if OEM Porsche shops are allowed or not - a Porsche tech at an OEM dealership who is not capable to adjust the car height with a Piwis seems indeed to be in the wrong position and should change his/her job.

I've done around 10 Cayennes (958) and Macans in the meantime, no issues whatsoever. I'm not a pro tech nor did I have anyone instructing me. Piwis guides you thru the process, capability to read and follow instructions is a prerequisite of course.

There was one single case where the whole thing got nasty: With aftermarket parts combined in an 957. You can't properly calibrate a modified Air Suspension (never ever try this), plus for a 957 you need the measuring instructions since the measurement reference points are entirely different.But we're in the Macan forum here so there's not much one can screw up using Piwis... so I won't get into details on 957 models.

If one wants to buy a module - that's one way to do it. If you know someone who can properly use a Piwis - this is a free (or very low cost) way to do it.

I don't know anyone in my wider P community and clubs who would spend lots of bucks for modules, all went with the Piwis way. Including 957 owners.

Says who? There are a number of dealers who have done this for for members here, sometimes with a bit of trial and error.

Say the dealers in Europe. In case of any warranty issues, dealer has to provide an up to date FAP (Vehicle Analysis Protocol). If the factory discovers a dealer changed your ride height, warranty is gone plus dealer is in trouble.

See my second point - I know some do within very little limits..

Best way to go on this is the Cete module as many of us have.

Why mess around with PIWS every time you want to change your height? I can do it from my smartphone while I’m driving as road conditions or my mood for different driving dynamics change.

And if there is a warranty issue, it’s very easy to hide the module from the dealer. Not only that, how many Macan owners have you seen with AS problems? Very few. This is not a Land Rover or a Grand Cherokee we’re talking about.

I also highly recommend the Cete module. So easy to keep adjusting the height until you get it just the way you want it. And it's the only module I know of that gives you the flexibility to adjust individual wheel wheel positions.

My intent was not a discussion pro/con a module, only a correction on how to properly use stored vs actual height values w/ Piwis and to prevent misery.

whoever likes to spend big bucks on Modules - may do so. ;-)

You mentioned your intent was to not start a pro/con discussion about modules, but yet your comment above clearly shows otherwise.

Very few of us have access to PIWIS for free or for little cost. With PIWIS most of us would have to lay out significant cash every time we want or need the height changed. To use your words “whoever likes to spend big bucks on PIWIS - may do so”. A module is a one time expense with substantial advantages versus PIWIS.

I suspect quite a few independent Porsche specialists do. I know of at least one here in New Jersey. And you can expect the cost to be less than the dealer will charge.

Can’t speak to Europe, but I doubt a lot of this is true in the United States. There are a number of dealers willing to change your height if you ask. If there was a real risk of being in trouble with PCNA, they would not do so.

I have never heard of an FAP. Does it show if the height was changed in the past, or does it merely show the current height settings?

A "FAP" = Vehicle Analysis Protocol is created in all warranty cases (before repair) with Piwis. It is also created for any sort of CPO vehicles and always sent to the factory by the dealer in case of delivery, warranty, major repairs, CPO inspection, SW Updates, etc etc.

Printed out it's several hundred pages of information, basically anything which is stored for settings, codings and flashes in all ECUs on board. Including e.g. # of flashes, failed attempts to activate functions, Piwis system nr used, etc... even your exact GPS location at the time of protocol creation.

As per ride height, the stored (=coded) values are stored in the AirRide ECU, along with other values. Hence, the factory can easily compare to previous data stored. By minimum vs the data the time of production or delivery.

(One common use is the evaluation of overrevs for manual transmission cars. High overrevs typically prevent CPO warranty, but goes to far for our Macans with PDK ..)

Some example for Air Ride data stored in this report:

Codierung: Fahrwerk Luftfeder + PASM (= Air Ride)
Codierung: Land RDW (= RoW)
Codierung: Motor V6D (Diesel engine)
Kalibrierung Höhe hinten links 447 mm (stored ride heights = values entered for calibration)
Kalibrierung Höhe hinten rechts 439 mm
Kalibrierung Höhe vorne links 468 mm
Kalibrierung Höhe vorne rechts 462 mm
Kalibrierung speichern ja
Sensor: Sensoreneinbaulage vorne links invertiert (Sensor Positions inverted / not inverted)
Sensor: Sensoreneinbaulage vorne rechts nicht invertiert
Sensor: Sensoreneinbaulage hinten links invertiert
Sensor: Sensoreneinbaulage hinten rechts nicht invertiert
Status: Bandendeinitialisierung ja
Status: Sensorkalibrierung ja
Status: Kundendienstinitialisierung ja

If they charge more than 100 bucks - I'd like to know what they do with all that time. If you're slow, it's a 30 minute job. If a dealer charges more than 200, he'll rip you off.

I'm not speaking about re-alignment, just the height re-calibration.

I suspect quite a few independent Porsche specialists do. I know of at least one here in New Jersey. And you can expect the cost to be less than the dealer will charge.
