e39 530i Manual - Shudders under acceleration

[mystery39 0]

My 530i has recently started intermittently having an issue where it shudders under acceleration and isn't delivering power properly for a short period (5-10 minutes) then goes back to normal like nothing had happened afterwards. Tends to happen when the car is cold, seems like a gearbox issue to me - anyone able to shed any more light on the problem?

Cheers

Cam sensors are a possibility too. Get it diagnosed by a BMW specialist, will be cheaper in the long run
