Hi everyone, long time lurker and first time poster! I've owned a 2017 Base Boxster for three years - picked it up with 13,000 miles on the clock and have since done around 20,000 miles with no real issues apart from a water pump replacement last year. I've had it maintained by a local Porsche specialist in this time. It's a PDK but I've pretty much exclusively driven the car in manual mode. A few months ago I started noticing a slight judder under acceleration when the engine was cold - I'm always very gentle with the car before it's warmed up, but gently going from say 20-30 in 3rd would generate a subtle but noticable judder / shudder. As soon as the oil temperature is above the blue (around 76 degrees C), this behaviour stops completely and the car drives perfectly. This has got progressively worse over the past few weeks - the judder / shudder has become quite aggressive, and a couple of times I've been pulling away from a roundabout when cold and the car has really lurched away. Again, as soon as the car is warm the problem disappears, and I've had no warning light / error message in this time.
The Porsche specialist took it in yesterday - they collected it from me and were able to experience the problem on the way to the garage, but by the time they arrived the car was warm and they couldn't reproduce it anymore. It was due an eight year service anyway, which was carried out, but no faults were found and no fault codes were present (they have PIWIS 3), although they did note that the turbo actuator seemed stiff, so they cleaned and lubricated it. I've spent a lot of time on this forum in the past and am aware this is a weak point of the 2.0T engine. I was hoping that this would fix the issue but I took the car for a drive this morning, and the problem is definitely still there. I'm waiting for a call back from the garage but imagine the troubleshooting for this will be quite complex!
I've extensively searched this forum (and google), but can't find another instance of this problem / how it was resolved, Has anyone had / seen this issue before? I did find post about contaminated fuel, but this seemed like a one-off for the poster that rectified itself over time. I've only ever put Shell V-Power in the car and it feels like the problem has been around too long for this to be a possible explanation? Thank-you so much for any input.
