Hello everyone my car has developed a nasty squeal and i dont know where it comes from we checked the intercooler pipes the intercooler itself (there is a lot of oil in there).But everything seems nice and tidy we checked the intake manifold egr valve and everything around there.I will upload a video c an somebody help? The turbo sounds ok under no acceleration and also the car has straight pipe 1.9 TDI AWX 131 hp 5speed.

Could be a worn or loose drive belt (e.g for alternator). Typically that will diminish after a bit of driving and is worse when cold.

But you can not recreate this sound while the car is standing still its only when you are driving under full throttle thats what confuses me

What it was ? Did you repair it ?
