Got a custom code phase 1 remap the other week and also replaced the standard dv with a forge 007p. Sometimes the car has no boost and feels like there is no turbo. If i turn the car off and on again its fine! The 007p was stuck closed so i took that off and put the standard one back on but the problem is still there. Got it on VAGCOM today and got the following errors: 17608 - Boost Pressure Control Valve (N249): Mechanical Malfunction P1200 - 35-10 - - - Intermittent 17705 - Pressure Drop between Turbo and THrottle Valve (check D.V.!) P1297 - 35-10 - - - Intermittent Can anyone shed any light - what does this mean? Is it the N249 that needs replaced? How easy/cheap is this to replace? Sorry for all the questions but any help much appreciated!
