    Default No Boost/Irregular Boost

    First question is could this be caused by the swirl flap linkage rod or the valves being blocked?

    Looking at the bar it appears to be laid on its side and has quite a lot of play in it up and down but still seems attached I assume this is not good.

    I do need to check if the car has a DPF as I am unsure. I have also cleaned the EGR and the boost sensor recently.

    This problem is driving me mad and I can't seem to fix it the turbo kicks in sometimes but not others and when it does it drops off altogether after just 1000 revs with a tug back on the car.

    Finally while accelerating in 4th last night the car just stopped accelerating alltogether, spanner light came on and couldnt go any faster with foot to the floor than i already was. This has now gone off again.

    Any suggestions or help is much appreciated

    You can buy silicone replacement pipes off ebay.
