Hello friends
Has anyone had this problem?
Seat Alhambra 1.9 TDI 2005
17954-Boost Pressure Regulation Valve (75)
P1546-35-10-short to plus
17957-Boost Pressure regulation Valve (75)
P1549-35-10-Open or short to plus ground
I already changed the N75 valve and the problem reappears
Any idea?!
Best regards

check WIRES! Becouse you have a N75 faults only, I think problem in wires.
Check N75 positive pin (Ignition ON) and negative from ECU. You can use small power control bulb for check it. Start VCDS N75 TEST and check positive and negative N75 pins.
