Seat Alhambra 1.9 TDi - Limp Mode Problem - bertie

Hello, l would be grateful for any experience/opinion as to a problem l have with a vehicle. It's a Seat Alhambra 1.9 TDi (PD) 2001 with 175K on the clock. Basically, everytime l accelerate to any degree eg overtaking, the turbo cuts out & the engine is put into limp mode. When you stop the vehicle, turn off the ignition, wait 30 seconds or so, then start the engine again, it's reset.

You need a code read to find the fault, sounds as though it is overboosting as you no mention you are low on power. Regards Peter
