P0236 Higher actual boost Pressure Vs Requested at idle

[Keagan245]

Experienced this problem since last week. Car would idle normally but every 2ish minutes would sputter and almost die but then save itself and idle would return to normal for the next 2 minutes. Only Requested boost would rise with RPM until 710mbar actual boost is reached and then both requested and actual values would continue to rise together. Car runs fine once on the move at all speeds apart from the occasional jerking when pulling off at the lights. Still getting the hang of VCDS but here are the values I’ve chosen on Advanced Measuring blocks. Pictures are too big to upload. Could it be more then just a bad boost pressure sensor?

Boost pressure control(n75) actual = 2%
Boost pressure specified = 300 mbar
Boost pressure actual = 710 mbar
RPM was 747/min

I’m also getting a p0236-000 implausible signal - intermittent

Boost Control Valve (N75) is quite a common failure on VAG cars therefore it maybe worth just changing it to see if that cures the issue.

Will update it once I get the chance to change it on Tuesday and will update you after
