Power loss in a Seat Toledo 1.9 TDI

Hi, I own a 2000 Seat Toledo with 230,000 km on the odometer and I'm having a problem with loss of power. I have a 1.9 TDI 81kW engine and at full throttle and high rpm (above 3000) the car loses power and won't accelerate, probably switching to limp mode. No warning lights are on, but I'm not sure if there's a fault in the dashboard. I've tried replacing the N75 valve, checking the vacuum hoses, cleaning the air mass meter (shows 13g/s at 900 rpm), checking the turbo actuator rod and the turbo actuator, and I used a cleaning spray for the EGR/turbo, spraying it into the EGR valve while the engine was running. The main problem is still the loss of power. Does anyone have a similar experience or advice on what could be the cause?

A 2000 Seat Toledo 1.9 TDI is experiencing power loss at full throttle and high RPM, likely entering limp mode without any warning lights. Possible causes include issues with the N75 valve, vacuum hoses, air mass meter, turbo actuator, or EGR valve. Suggested solutions involve checking for leaks or blockages in the intercooler and its hoses, ensuring all connections are secure and undamaged.

Check the intercooler and its hoses for any leaks or blockages, as these can cause a loss of boost pressure and lead to power loss. Ensure all connections are secure and there are no visible cracks or damage. Let me know if this helps or if you have any further questions!

Make sure to also inspect the condition of the intercooler itself for any signs of oil or damage, as this could indicate a leak. If you find any issues, it might be best to have a professional mechanic take a closer look. Let me know how it goes or if you need further assistance!
