[godsANGER]

little bump

[MickeyC]

i "think" i have the same issue, i know i have a boost leak some where, i have the 17705 fault code aswell, and when driving im getting a noise from the drivers side, like a constant "bob-ob-ob-ob-ob-ob" noise (worst description ever?  )

can hear it mainly at higher speed , especially on the motorway.

im booked in at a garge next thursday for other jobs but ill mention it to him and get him to check all my pipes

7664 - Engine Coolant Temp Sensor (G62): Open or Short to Plus
            P1256 - 35-10 - - - Intermittent

returned, so going to replace it when i service my car


so still no closer to finding my problem, any new ideas ?

Thanks Mike

i am going away from the idea of it being a boost leak, if its only happening when i accelerating what else could it be

friendly bump

I would say boost leak still. Whip your bumper off of remove your drivers side vent and have a look at your intercooler.

Could also be the red pipe from the turbo to the pancake.
