I just bought myself an A3 1.8 turbo sport on the weekend and noticed yesterday that on the cold engine start there was a rather loud screeching/squeaking sound coming from the engine. I tried it again this morning and the same thing. The annoying noise only lasts about a minute but it is very loud and sounds like an aircraft. It's hard to explain so I created a video of the sound. After a minute the sound goes away and is then followed by a strange whistle noise (you'll hear it in the video).
Does anyone know what this could be?
The cars done 91k miles and hasn't had the turbo changed.
I've read the other posts on the forum regarding similar noises and I tried the common fixes including turning off the climate control and then starting but I'm still getting the same noise.
Just a bit worried that's all and won't get a chance to take it to a garage until the weekend. In the meantime don't want to drive it could be something big like the turbo
Thanks in advance.
