PDK problem - no reverse
Gents, need a little help here. I also posted in the 987 forum but wanted to get some eyes on it here too in the event someone may have some feedback.
I have 2011 Cayman S with factory PDK. The car is a track only car for me (DE and open track, no wheel to wheel). I has a guard LSD as well as PDK radiator added.
Sometimes, when I go to reverse out of the trailer, or out of the garage, after the car has been sitting....I have no reverse.
I can hear it go "into" reverse, but if I apply throttle its as if the car is still in neutral.
No codes, no CEL. No difficulty moving the shifter. If I go to "drive" it immediately works going forward, but I may or may not have reverse.
Ordinarily I wouldn't care, but.....on track outs coming out of fast turns, the transmission sometimes will fail to shift and its extremely unsettling to the car at speed, as if it cant make up its mind what gear it wants to be in while running is sport plus.
I can't make it happen, its completely random so my local dealer has no idea......
thoughts??

Did you have the latest PDK software update done?
I've never had problems you have described with backing, but I have had the vehicle go into emergency run mode randomly a few times and fail to select a gear when driven aggressively in sport plus out of corners- this occurred after two DE days at PIR- Five 20 minute sessions each. (turned out PDK is very sensitive to voltage) - Coil pack needed replacement and battery got replaced which actually fixed the issue. The dealership thinks the coil pack might actually be unrelated (however voltage again dealing with) and stated that battery voltage is critical to PDK.
Hope this helps....
I'd look at your battery
PS just adding - my car started and ran fine but battery stress test is where it failed.

This is a 7 year old thread. Appears you are searching PDK and inserting your business card at will. OP is in the USA and doubt he will ship it to Europe when there are options in NA.
