I've done this to my leon cupra, removed the n249 crap something else and the SAI pump and using scan gauge I haven't had any faults come up......yet fingers crossed
 
Ok, just one question is this that error with N249 ''17608 - Boost pressure Control Valve (N249): Mechanical Malfunction P1200''

thx
