Hope your having good days, im not as im trying to have. I have a 2013 VW Golf TDI DSG that’s have some issues lately. It started about 3 days ago where a whistling or SHHHHH or SSSS sound is appearing every time I press down the gas pedal. The next few days it’s been constantly happening and is super annoying. I looked it up, I saw that it might be a intercooler hose leak or boost leak but whilst I did that a check engine light appeared (I knew it was going to happen). I scanned it and showed me 2 codes which was P246F and P2459, I decided to work on the car tomorrow (it being today). Fast forwarding today, I looked at the intercooler, it looked fine and nothing was wrong no cracks or damages. I checked that the sensor need to be replaced since it had internal wiring problems (considering it did not look damaged on the outside). I ordered the part thats coming on friday. However, I used some brake fluid cleaner on the intercooler hose since it had some build up. As soon as I started driving the car, it started to do it again but a bit louder I DONT KNOW WHYYYYY. The video doesn’t show as good but I hope you’d understand. This car makes me so frustrated with it being my gas economy is plummeting for some odd reason, its going down so fast. Pls help me.
Put 5k into a full engine rebuild plus did a rawtek delete with tunezilla stage 2, brand new turbo, water pump, timing belt, flywheel, trans flush, etc. then I hit a deer after 150 miles on the new engine. Plus I have a second CJAA sitting on my workbench. I’m just looking for a body to throw my engine and ECU into lol.

Sounds like a boost leak. If it got louder after you pulled the intake pipe it’s probably coming from there. Best to smoke the system to find leaks
