Hi All,
Odd one this, haven't been able to find much info on it either. The car sometimes starts with the EPC light on accompanied by a "Stop Start Error" message on the MFD and goes into uber limp mode (25mph is an acheivement). Once it was also accompanied by the check engine light too, although this cleared itself after a few runs. VCDS recorded this (which is also why I knew it would be safe to carry on driving):
1 Fault Found:
10478 - Charge Pressure Control Actuator
P334A 00 [173] - Electrical Malfunction
MIL ON - Confirmed - Tested Since Memory Clear
Freeze Frame:
Fault Status: 00000001
Fault Priority: 2
Fault Frequency: 5
Mileage: 73898 km

I did have to unplug this actuator when I changed the air filter for better access not long before I got this error but I've checked it's in properly a fair few times and have also cleaned it with contact cleaner for good measure. So it's either I've some how managed to disturb the loom into the plug (unlikely I'd have thought), or it's just a coincidence.
I'm pretty sure it isn't due any software updates as it looks to have the actuator shim that was fitted during the 2012 recall. The really wierd part though is the car runs totally fine as long as it starts ok without the light..
Anyone else had this before? Is it new actuator or dare I say it, new turbo time?
Thanks in advance!
