2015 Macan Turbo: When backing out of driveway on cold mornings, when I turn the wheel, there is a very pronounced clunking feel/sound. I'm used to it, but it is so bad that passengers think I backed into something. The harder I turn the wheel, the more severe the issue. Not an issue when warm. Anyone else deal with this?

 

Sounds like a worn out bushing or ball joint or something...probably need to get suspension checked.

 

I agree with #1SomeGuy assessment - you don't mention the number of miles on the car, but certainly could be a ball joint, shock mount, bad sway bar link, etc. How is the handling in general? Sounds like something has play that shouldn't there and you should get it checked.

 

Look up the Ackerman Effect. Might be more info on it in the 997 forum, but it's a suspension geometry thing so doesn't matter.

 

Thank you Petza914, this is what I was looking for. I remember reading about it on another forum, but couldn't remember the details. Sounds like the newer the tires, the less the problem.

 

Yup, just listen to the answers you like and ignore the potential for problems...sounds like a great idea.

 

Wow!

Nice animosity... Next time, try:


It could very well be the Ackerman effect. Read up on it.

 

And the colder the temperature, the worse it seems to be. The only time my 997 has done it was when it was 20 degrees.

 

So he shouldn't check to make sure it's not something worn out? Should just assume it's the suspension geometry and call it a day?

Colder makes bushings stiffer and fits looser...which lends itself to parts wearing out.

 

Same here. Definitely a winter thing.

 

The Ackerman Effect on cold is worse because the tires lose their pliability so instead of being soft and squirming when that geometry adjustment happens, they're cold and hard so they hop instead. You really think something is broken or you've run over something until you know what it actually is.

By all means have the suspension bushings and control arms checked out, but of they don't find anything wrong, no need to chase your tail as you know the other thing that can cause this now.

 

are you sure it's now rear wiper? I just has similar occurrence and took me 10 mins to figure out it was the wiper.

 

If you had half a clue, you would know it's Ackerman Effect. Try to learn something instead of showing your ignorance.

 

Wouldn't it be more ignorant not to inspect his suspension and alignment to make sure something else isn't going on before writing it off to Ackerman Effect?

Also, if you search for instances of loud clunks from the Macan when backing up, most point to transfer case issues, so probably should check that too.

But hey, who am I to suggest inspecting for known causes of clunking noises, I only have half a clue and am ignorant apparently.

 

I agree..clunking sound when turning the wheel while reversing is a known symptom of the transfer case going bad, so I would check for other symptoms.

If it was a suspension related issue it wouldn't go away when the car is warmed up.
