Peugeot 307 Diesel: Check Engine Light and Stalling Issues

I own a 2006 Peugeot 307 with a Diesel engine and 224,000 km on the clock. I'm experiencing a couple of issues: the check engine light is on, and the car stalls while idling. The diagnostic codes indicate a problem with the turbocharging pressure, which triggers the safe mode when driving on the highway under load, such as climbing a hill at 6% inclination at 150 km/h. Interestingly, this issue doesn't occur when driving up a mountain with a steeper incline at lower speeds. Could the problem be related to the speed or exhaust pressure? I've already replaced the turbo, air mass sensor, and had the ECU checked at an official Peugeot workshop. If anyone has insights into what might be causing this problem, please let me know. Thanks!

Check for any vacuum leaks or issues with the vacuum lines connected to the turbocharger. A small leak can affect turbo pressure and cause the symptoms you're experiencing. Inspect the hoses for cracks or loose connections. Let me know if this helps or if you have any further questions!
