I previously had stage one with no issues. 5 Turbo Trouble - Skoda T'internet says well known problem and the linkage is adjustable via 2 torx screws. I started getting Service Electronic Throttle message , CEL ( P0234-00 turbo overboost ) and going into limp mode in the late Spring on my 2015 Ecodiesel at about 29K miles. The dealership also stated to Polaris that it thrown a temp code 26 times and the over boost code and the 2629 with 3 underneath code after the new ECU and also an O2 sensor is well and a T map sensor too. This is mounted next to the EGR valve intake on the manifold, and it get hot and oily, thus giving false readings back to ecu on the manifold pressure, since that differs from the turbo boost sensor it assumes the turbo is in over boost. When it comes to diesel engines, including the Ford 6. If you need any assistance or advice, please contact us.
