So how does the service manager determine that both turbos instead of one need to be replaced by sound alone just by driving the car? He must be real good.

That was just in case they wanted to start a new discussion on what was changed in the new turbo. Ha!

Anyways, i brought my car in to have the turbo checked. Wonder if they have other means to replicate the issue without driving the car and flooring the pedal.

Keep us posted. I believe you mentioned you were getting a whistle/whine noise from your turbos, right?

As I just mentioned to Avadis53, that I'm willing to bet that the sound that they heard was from the LDP, I will remove them for peace of mind, the last thing I don't want to hear when they raise the car up is sorry, you have to pay.

Correct. I planned strapping on a GoPro in the engine bay to record it but there wasn't enough space where I can safely mount it on. Hopefully they will be able to track where that noise is coming from. I'm just assuming it's the turbo mainly due to the sound it makes ("wooosh" ...or maybe it's really saying "wuusss" to me. LoL). I also mentioned the TSB for infotainment (going black on reverse if I didn't wait for it to load completely).



Meanwhile, my loaner car is a 2019 QX50 which, coincidentally, was Hunter's loaner car when he brought his Q60 in for some special engine service. He picked up his car last night and that's basically what the advisor gave me this morning. I must say this VC-turbo is fun to drive. Doesn't sound great but it's smooth and pulls stronger than I expected.

And they said that I can drive it. If it gets louder I'm bringing back in.
