Hey everyone, i own a 2010 porsche Boxter 2.9L with the PDK transmission.. yesterday after leaving the car for a 4 days i started it and went for a drive.. when i turned it on again, i got a warning message “emergency transmission run” and the car became very jerky through gearshifts and wouldnt accelerate properly.. after turning it on and off the message went away and it drove just fine but then it kept re-appearing mid drives and becomes very jerky and clunky...ive noticed since i had the car that the gearbox was sometimes clunky or would make a noise when changing gear but the dealership said that was fine and normal since its a PDK, the car is at 59,000km so its time for a transmission fluid change... could this be a low voltage problem, or transmission fluid? The reverse gear works just fine.. has this happened to any other owners?

As I understand it, a PDK transmission requires both a transmission fluid change and clutch fluid change. The clutch fluid change needs to be carried out twice as often as the transmission fluid.

 

If your problem is not software-related, I'd hazard a guess at a clutch fluid change being necessary.

 

Odd that a Porsche dealer would state that a clunking PDK was "fine and normal" !

@wizard Thanks alot for that, really had no idea about the clutch fluid.. i hope thats all there is and it isn't any broken component.. and about the noise, when i asked them they said that a PDK in essence is a manual transmission with automatic function... so such noises are normal...

after asking around some shops some say its very possible that its the software needing reprogramming or an update, or low voltage, or a fluid flush and change.. i have booked a service for tomorrow and will Update The problem

Apparently, the entire issue was not PDK related... its was just a faulty Mass Airflow sensor and a bad battery.. both changed and it tuns like new.. still jerky sometimes when shifting from 1st to 2nd but the dealership confirmed that there was nothing wrong and its normal for early stage PDK boxters and cayman (2009-2012)

      Not many problems with the car but cruise control doesn’t work and the spoiler only extends halfway or so.
       
      Current actual problem with the car is that I  can feel vibration or shaking in the steering wheel (and in the car to a much lesser extent) after shifting into fourth gear. After shifting into fourth gear, the shaking seems to persist even as I slow down, or after shifting into fifth. It will persist even if I shift into neutral but will stop after I come to a stop.
       
      It’s strange to me that this is the case when gears 1-3 don’t have this problem. I am guessing that it’s an issue with bearings or alignment in the front wheels since i’m feeling the vibrations in the wheel but hopefully someone here has a better idea.

      Tried googeleing it but couldn’t find what I was after.    Was curious if anyone knows what type of flat 6 the 986 boxster has?
       
      Is it a a true boxer engine? Or a horizontally opposed flat V?     True boxer meaning it has individual crank pins for each piston and is a true 180degree angle.    Thanks in advance

      The rear window on my 2001 S has separated from the canvas, and the tan top is dingy and past its prime. I no longer have a garage, so I am forced to outsource it. I would appreciate some informed opinions.
       
      I'm looking at a GAAH A5 Acoustic glass window top. The dealer is saying $2,700-$3k installed. A reputable convertible/interior specialist is coming in at $2,200. The dealer talked about needing to buy additional sound insulation, clips and etc., which is either building in additional profit, or it may be totally justified because they have experience and might provide additional quality. I don't have an excess of cash for a 18 y/o car so I'm soliciting experienced opinions:
       
      Assuming the local top specialist is truly skilled at their game, should I expect that they can handle this, along with connecting the heating element?  I doubt they have done many A5 Acoustic glass retrofits, whereas the dealer has likely done a few. If I go with the local specialists, are there some unique things I need to specify they order/replace/pay attention to? Should I give more weight to (a) Porsche dealer that only occasionally does a top or (b) the people who do tops all the time, but just not Porsches?    
      All informed opinions are welcome. 
      Thanks!

      Recently I had been noticing issues with my cooling system the coolant temp guage would go past the 0 on 180 and I wouldn’t hear fans or anything. (Already tested fans and resistors and relays).   The temperature Will continue to creep up if I sit still, with no signs of fans, AC OFF.

      I replaced the coolant temp sensor. Problem fixed!! Then same issue again it seems after a week of driving.  

      Now i currently have ordered another temp sensor just Incase I maybe did something to cause the other new one too fail, I’ll be changing it again today.

      However I was doing the climate control hack to check my actual temperatures today while doing a short troubleshooting drive. And I noticed my oil temperature said 0, which is physically impossible 🙄


      Is it possible the oil temp guage is throwing off the coolant sensor?    Is it even possible for the oil temp sensor too go bad but not the oil level sensor? (They are a 2 in 1 sensor)   

      THANK YOU IN ADVANCE
