Hi all I have a mk2 cupra running stage 2+ 370 bhp with all supporting mods and I've lost all boost , however it still makes the fffff ttt ttt ttt noise lol. It still drives absolutely fine and is not blowing any smoke. I've changed the n57 valve and still nothing. Then I plugged it in and have 2 error codes. P0033:004/00051:004 which comes up as bypass valve control circuit no signal/communication. Also P0243:04/00579:004 which is waste gate solenoid A no signal/communication. I've checked the wires and seem to be fine. Please help
