I think I've figured out what is making the noise but I don't know what that thing is. Let me explain if I can...when the engine is cold or the car has been sitting a while and you start and drive off slowly, once you've got some speed and are doing ~20kph some motor or solenoid engages, often happens just as you shift into second gear. Is it part of the turbo, boost control adjusting itself? EGR solenoid?

Whatever is supposed to be activated just as you get going is whats making the noise, getting stuck or not engaging properly
I think it's something to do with the ABS - it's always around 20km/h and near the first to second gear change.

Mines done it since it was new, thought it was normal, sounds like it's coming from near the pedals/low in engine bay

I have an LV TDCI - 207,000km
