no it's not mapped mate well I've not had it mapped anyway. It's just not pulling smooth at all throu boost. I've done the relevant tests on the n75 and that is fine so I had it read and it came up with this fault. So should I ditch then249 then?Guessing you got this one..

17608/P1200/004608 - Boost Pressure Control Valve (N249): Mechanical Malfunction
Have you done an N249 bypass? this fault code comes up when the ECU tries to use the N249 to open the DV and dump boost when it detects an issue like an overboost situation... if the ECU can't detect a drop in pressure (as this is what it is trying to achieve) then it will throw this code...
Is the car mapped?

not really mate no think I will treat it too a 007p tomorow what ya thinkDo you get a 'chuuu, chuuu, chuuu' type of noise from the DV as you let off on part throttle or while revving the engine from idle?

it idles fine mate but jerky power delivery which is why I thought originally it was the n75 but checked that and all ok. Polarity fine onit and working fine so read my codes and this came up.silly question... I assume the car is running ok? you just scanned and came across this fault?... have you cleared it and has it come back since? if not then I would just not worry about it right now...
