hello, I have a problem with my cayman 718, the PDK gearbox with a reduction on the machine gives a strange sound from 2 to 1, the sound is comparable to putting the wheel on the sewer, does anyone have something similar in their cayman / boxter 2.0T 300HP ?? ? Best regards ziutek-PL
-cayman has driven about 2 thousand km
-automatic mode gearbox

Are you using manual mode? Does it do when you come to a stop in automatic mode? If so, take it to your Porsche dealer soon.

automatic mode, my dealer claims that the car is all OK and that you hear an active differential, sorry for my poor English :|

No worries. Literally.

What you describe has been discussed by forum members in several threads, particularly this one in the Engine and Technical Discussion subforum. It is entirely normal. My car (718 Base, as we Yanks call the 2.0 300hp model), which is nearly a year old, has about 12k miles on it, and goes through stop-and-go city traffic on a near-daily basis, does it as well. No issues.

hi, i.e. the reduction of gears from 2 to one with a strange sound give a punch in a normal porsche ??? the ride is always in U mode on a chrono package, nowhere on the forum I can not find a similar problem to me ... but how was the problem raised, I am sorry ...

The 718 testcar and the one I drive now both have this. As if the gearbox doubts what gear to pick at low speed.
The dealer told me it's normal for a PDK.

And, to continue that thought, PDKs have done this for years -- not just in 718s.

OP: Stop worrying. By pretty much all accounts, it is normal.

I also brought my car into the dealer a few weeks ago for this exact same noise, and as everyone, and the dealer has stated this is "normal" and no fault codes, is what they told me. So I just don't worry about it and enjoy the ride.

OK thx...

And one more to chime in, my brand new BS has the same clunk in the transmission. Seemed to have gotten a little better as I put some miles on the car (car now has 750 miles). I kind've got used to it, so a minor annoyance at best.

 

[My718isPorsche#5]

I never heard the "clunk" until I unplugged the sounddoktor.

Hello everyone,
First of all congratulations for a great forum! This is a very helpful forum and I already picked up some tips. In May 2018 I picked up my new 718 Boxster S, sapphire blue with dark grey platinum 20" wheels, an awesome looking car! I've driven about 1500 miles so far. Early on I heard clunky noises, likely coming from the gear box (I'm not a car mechanic …). It sounds like metal to metal and appear when driving in low revs (1000 RPM) in 2nd gear only. It does not appear at other revs or in other gears. The situation typically appears when slowing down for tight corners, or speed bumps. I can also reproduce the sound in automatic as well as while driving in manual.
At the Porsche garage they initially acknowledged the problem and first replaced the hydraulic system of the clutch, and when that didn't solve the issue, they replaced the entire gearbox. But the clunky sound is still there. Now Porsche claims this sound is normal for this particular engine. I find it beyond annoying as people are turning heads not because of the car but because of the sound.
I uploaded a video (ignore the video part and focus on the audio), where I slightly accelerate in 2nd gear, then brake until 1000 rpm, slightly accelerate, brake until 1000 rpm etc. Video can be found here:

Is this the sounds you all experience? This is my 1st Porsche and although I love everything else about the car, this is very disappointing

Thanks a lot!

My CS has the same or a similar issue; namely a very noticeable metallic clunk when dropping from 2nd to 1st coupled with, at its most severe, a lurch / shunt.

My local OPC is, like others it would seem, suggesting 'they all do this'. But I've not noticed it on other 718 and 992's I've driven. Plus, there appear to be just as many folk, if not more, saying their cars don't do it. And even if this was a genuine PDK trait, I find it hard to believe that it wouldn’t have been commented on in reviews. I‘ve read 100’s of Porsche reviews over the years and don't ever recall coming across a comment about it...and journalist are pretty quick to pick up on the slightest shortcomings of any car, let alone Porsches etc.!

Has anyone managed to resolve the issue with their OPC?

Journalists simply don't keep the car long enough for it to register as an oddity.

Look: Not everyone is going to mention this trait every time they talk about a PDK-equipped car. But the simple fact is that the PDK has been around for more than a decade, and there's documented proof of this being a trait of the gearbox since that time. If VW AG or Porsche hasn't seen fit to address it in that long amount of time, why worry about it? I don't ... in fact, I consider it a point of pride in the mechanical-ness of the car.

Yes, as was stated, we have discussed this before. Mine does it, especially in Sport mode. I don't think it's anything to worry about.

One thing you may want to do is to allow the engine to warm up enough so that the idle speed goes down to around 800-900 RPM or so. If nothing else, this reduces the slight clunk you may hear when initially driving off from a cold start. The people at the Porsche PEC recommended I do this before engaging any gear. This reduces the slight clunk most automatics make when the engine idle speed is higher. It takes about a minute or two (from a cold start) in my car.

To some degree, the "downshift to 1st clunk" is a reflection of the fact that 1st gear multiplies any gear-train "lash" because of the added gear reduction.

By the way, I have a GMC cargo van that has a "trailer towing" button that reacts similar to the Sport button in my Cayman: it "holds" gears longer and downshifts earlier. I've noticed it also creates a slight clunk when it drops into 1st when "trailer mode" is active.

My 718B PDK gives me and the audience a "clink clonk" if i drive slow in second gear specialy when rolling with low throttle over speed bumps or bumpy roads inside the city. Dealer says "normal". So i belive ... I got a 718C GTS last time my 718 got a service for 2 days. Same there but with closed roof not that anoying inside the car. With open window it is the same noise. But I found a "workaround" in handling the throttle to reduce that effect in slow driving... "clonks" become rare.



So do not worry about that. In full throttle all is fine and much more fun...


btw: I love my "small" 718 Boxter..

 

[wriggly]

I don't hear this clonking in my Cayman....but I am getting hearing aids sometime this week.

 

[Semitone]

I never really noticed the "clunk" in the past. Now I hear it all the time. I hate all of you!!

Nice day here today and I just got in from putting some miles on the Cayman. And sure enough I had to go and listen for the clunk. And dang it, mine does it. I never noticed it before.

2018 BS, 2500 miles, been clunking since day one.
