Please forgive me if you have already addressed this issue -- new to the site and I am trying to help a friend fix his "baby".
Need help with a completely stock 2005 legacy wagon that pings on hard accel and you feel it hold back for a sec then come back on boost and ping then shut down or "limp" then flashing cruise light and P0244 for boost control. the car runs fine under "normal" driving conditions as long I stay off the higher boost levels. I also have a leak from my Intercooler tank seal which I suspect is due to overboost. Any suggestions? I don't have any gauges so I don't know how much boost sets the code or how much actual boost the car is making but suspect Waste gate or Waste gate control solenoid. Then will replace Intercooler.
2005 Legacy Wagon, 2.5L DOHC Turbo
Car is COMPLETELY STOCK, friend has had since new.
He loves the car. Just can't figure this one out. Very mechanical I am just "new" to issues on this car.
