Hello, a few days ago, my car started making strange noises from the engine. It started off mild at first but gradually got worse; however, I needed to continue driving. The noise was most pronounced during acceleration, and I felt like the sound was synchronized with how the turbo was pushing. It sounded somewhat high-pitched but also deep, with a slight knocking noise, as if something was rubbing against each other. At one point, the car went into limp mode, which turned off after I restarted the engine. However, a little while later, the car stalled and couldn't be restarted. During diagnostics, I discovered the problem code P0299 - Control Range Not Reached, which means the turbo wasn't boosting, likely leading to the car going into limp mode. I'm not sure if this error is related to the noise. I'm somewhat concerned and think the engine might have seized up. I have an appointment with the service, but unfortunately, they don't have immediate availability, so I'll have to wait a while. I'm attaching a video of the problem. video of the issue I would appreciate it if you could provide any insights on what it might be and if it's something that can be fixed. Thank you.

Hello, I need advice on air conditioning. It's acting weird. If I set a temperature on climatronic to 18 degrees and outside is 25 degrees, I press AUTO and the AC starts colling. After a while, cold air stops blowing from air vents, although the AC output is at max (compressor shut-off code is 0). I have found that the current and the specified value of the potentiometer g143 (air recirculation flap v113) are different in this state. Picture from vcds below. If I press ECON, wait a while and then press AUTO again, the air conditioner will start cooling again for a while and then cold air stops blowing from air vents again. Do you think it could be caused by the control motor v113? Thank you.
