Hi just wondering if anybody has any idea how this might be fixed. I have a Skoda Fabia 2013 TSI which keeps entering limp mode completely randomly. It is producing codes P334B and P334B. The turbo failed on the car recently and was replaced. The actuator was also replaced with a genuine one but the car was overboosting a lot. The mechanic put the non genuine one that came with the turbo on and that seemed to fix it but the car keeps entering limp mode still. I took the car to the main Skoda dealership who calibrated it and reprogrammed the throttle valve. They said they couldn’t find and issue and it drove find for a couple of days and then entered limp mode again with the codes above, P334C is a new one though it’s only came on after they adapted the actuator. Any ideas would be appreciated. Thanks
