Cayman 718 - A few bits need fixing

Hi Everyone,
I thought I would let you all know the car is booked back in the garage for a couple of things to get fixed which one was a surprise; the tailpipe is rusting and this was noticed when the car was just a month old but due to work commitments this week was the first opportunity I had to take it to the garage and they agreed to order a new tailpipe. The other niggle is the back boot only closes if you slam the boot down which goes against my instincts; the garage are going to adjust that at the same time as replacing the tailpipe.
I have attached a photo of the tailpipe as I thought those who have purchased a 718 might like to check theirs.
Regards
Diane
 
I had exactly the same issues (rusting tailpipe) on my Cayman R and now on my current Cayman - both have the sports exhaust and rust spots appeared quickly. The pipes on the Cayman R were replaced but I'm waiting until I take the latest one in for service before sorting out the rust on these (as it's a bit of trek to my nearest OPC).

Seems it must be a common issue....cheap steel covered in Chrome :(

 
In a way it good to know I'm not alone but still disconcerting when you buy a brand of this kind. I don't recall this happening on my last 3 Porsche's

 
That's bad news Diane. Completely unacceptable that the exhaust tail pipe shows rust spots on such a new car. This should not happen on a premium brand such as Porsche.

I am one of those fastidious types and coat my exhaust tail pipes with Autosol chrome cleaner about once a month in the winter, and periodically in the summer. My 3 previous Caymans have therefore not developed any rust problems on the exhaust pipes with this Autosol protective treatment. Halfords stock it.

Regarding the rear hatch closing, I don't slam the hatch closed either. I let it down by hand until it rests on the latch, then press the hatch closed with the palm of my hand.

BTW, I've had my new 982 CS paint work treated with Geyol ceramic hydrocarbon coating. The result is impressive on my Graphite Blue CS. Before the ceramic coasting was applied I really had difficulty in seeing the metallic flakes in the paint. After the treatment not only did the colour seem richer and deeper, I could actually see the metallic flakes in the paint for the first time, especially in sunlight. I rejected my OPC's offer of the ceramic coating for £499. Instead I enlisted my next door neighbour who has a car valeting business to apply the coating for me. He took 5 hours to do everything, paintwork, carpets, glass, and wheels, all for £150 including materials and labour. Needless to say I'm delighted with the result.

Sorry to hear of your issue, I had my single tailpipe changed to black twins as prefer the look but at 4 months old & with 2k on the clock there was no sign of corrosion when removed so maybe your just unlucky. The tailgate issue is interesting as mind shuts fine if dropped for the final 6 inche but the loan car I had sounds like it had the same issue as yours, unless slammed from a height it would pop back up & need pressing down.

It appears to me that these early build cars have some foibles to resolve, hopefully more recent builds are better...

 
Unless you leave a window open partially to relieve the pressure build-up, I wouldn't recommend slamming shut the rear hatch....it'll just bounce back up.

The best method to use is that recommended by Brian - lower it down onto the latch and then press firmly on it to close.

Thank you Jeff for your endorsement.

The experience with my first Cayman 9 years ago has proved that slamming the hatch closed may also damage the gas filled hatch support struts. I had to have both support struts replaced on my Gen 1 987, fortunately under warranty at the time. On reflection, this damage may have been exacerbated by me slamming the hatch closed as I had previously done with my Mini Cooper S JCW. On subsequent Caymans, I always lowered the hatch onto the latch and pressed it closed, with no more strut replacements required.

There is a method of setting the windows to drop about 40mm whenever the hatch is opened, it requires the use of a PIWIS unit to switch on the function since the Boxster drops the windows to open the roof it just allows the same function for the Cayman hatch which when closed raises the windows.

I had a friend and fellow club member do it on both my 987.1 and 987.2 Cayman S and it works a treat.

As Brian has said, I had to do this on my 981S for the first couple of months. I thought it was the newness but now it closes fine. I also use autosol or T-cut on my exhaust and haven't had any rust issues in nearly 12 month of ownership.

I thought I would see if this is possible with a 981. Apparently not, with the 987 ECU/control units it is possible to make changes at the control unit level and this was one aspect that could be changed.

With the 981 more functions were integrated into the ECU and this is not possible. Per Exeter Centre where we had a good trawl through PIWIS...

 
Hi

Quick update. Car was in the garage on Friday for the tailpipe to be replaced and the rear boot to be adjusted. I'm pleased to say both are now fixed and the boot is working fine. I'll take note of Brian's advice about using Autosol.

Thanks to everyone for their advice.

That's what the forum is all about........receiving good advice.

As some of you will know already, I'm from the far north of Scotland, so I value the communications on this forum. There is a lot of knowledge out there......

I'll be venturing south in May, far away from my empty mountain roads and into the real world for the PCGB Anglesey and Llandudno events. It's good to have face to face contact with contributors to this forum, as it was last year. It'll be good to meet up again.

My review of the 718 CS PDK as I have specced it, will follow the Anglesey track day. It'll not be just another road test, more like a reflection of my opinions of the 718 CS compared to my sublime CR. Expect some pithy comments.........
