Thats cool im gonna switch them because my car lost all power but its not in limp mode, The car lost power one day and i turned the key on and off and the turbo came back on, which is limp mode but this was the only occasion. I blew a coolant hose that day so the car sat for a few days before the new hose came in. Then while drving my car i had no turbo, so then i cleaned the N75 and the went for a drive, the car boosted but it the boost flucuated, i read the codes with vagcom and got the negative devation code, i then chaeck the acuator everything was fine with mighty vac it held at 15 and moved freely, i then looked a the MAF with vagcom and the actual on goes to like 550 and idles at like 400, car doesnt run better with the MAF unplugged. I replaced all vac hoses, i tried putting in that other solenoid n18 or n239. I checked the boost hoses and the intake hoses. The last time the turbo was working, it almost sounded like a blow off valve. Would a map sensor make the MAF all crazy?
