Technical Stilo JTD 8v p0235 error

[sebastiaoest]

Hi, everyone! My Stilo multiwagon JTD is having a problem. When the car is cold (in the morning), it starts and runs fine for a couple off km. Then, the engine failure warning pops up and the car enters safe mode (becomes very slugish, like it has no turbo), and stays like that untill many hours after, sometimes until Next day. Scan shows error p0235 (no other codes). When i get live data, before the warning the Boost pressure looks Ok when compared to the expected Boost pressure. When the engine fault warning comes, the Boost pressure drops to a constant 282 mbar, and its stays like that. I am very inclined it is the MAP sensor. What do you think? Also...I tried to remove it but my hands are so big could not reach the Bolt... any other ideas to take the sensor off? Thank you all! Cheers
