What should I chack, have had this code once and cleared OK but want to prevent re-ocurrance

17705 P1297 Connection turbocharger - throttle valve pressure hose

do a search for 17705 been covered many times

as said been covered a lot but mine was the N75 valve has been changed to the wrong one.

I'll just start by looking at hoses, there seem to be 5 or 6 reasons for this code from hoses, to valves and pipework.

Exactly, its a pain in the ****.

For some reason Throttle Body cleaning seems to help it.

it can be

1.Pipes

2.pipe at the Top of the D.V,it leaks....re-tight'n

3.Throttle body

4.N75

It normaly pops up after a Remap......r Air fillter....ie K and N job.

i still have one.......its a *******........im sure iv forgottan a few.....!!!!!!
