Overboosting! Apparently

[sirjimalot]

Ok so my car went into limp mode tuther night,

today at work i put it on solus diagnostics and got a number of fault codes.

n249 valve failure (already bypassed)
n211? secondary air valve-failure-intermittent

and something else i dont remember wht it was,

but it said 'maximum boost pressure exceeded'

Anyways i cleared the faults to see which came back and surely enough two mins down the road it went into limp again.

Can anyone shed any light on the situation for me please

Cheers

sounds lke you've bypassed the n249 and not left it plugged in electronically? likewise with the N112 it should still be in with tubes and wired in?

or maybe you've plumbed it in wrong? e.g. n249 where n112 should be and other way round

well the n249 has been about for about 3 weeks and all was fine but then the other day i unplugged the n112 to move sumit and then later that day it went into limp.

when you unplugged the N112 what did you do with the pipes that were ran into it?

 

[sirjimalot]

left them in because i plugged it back in like 2 mins later
