I have a 56 plate golf tsi, with boost issues it has 3 codes stored:

.008801 Boost pressure control valve mechanical malfunction

.004269 magnetic cluch for supercharger open circuit

.008802 turbo/supercharger boost pressure not detcted mechanical

i was wondering if anyone has come across this before, any help advice would be good. i am going to check the wastegate arm and see if that is free had problems with these before but not seen the second code before!!!!
