Need a bit of help lads and ladies. Have just been out to a customers B4. Poor guy only picked it up fron a dealers yesterday and it died on the way home. its showing codes 31 and 11-throttle pos sensor and crank pos sensor-but it seems like the starter has also either stuck or failed so i cant clear the codes and drive it just yet to see if they return. He also told me the car seems sluggish and i found that theres a short pipe missing off the top of the actuator on the primary turbo-i imagine this would cause the car to bleed some boost?
