Ok update, fault code has read Code 2885 is for Boost Pressure Control Deviation, plausibility.
Now i have search various site and have come up with this info from NAM ( Credit to Simpson GI for info)
After having a new engine installed a few weeks ago my P2885 code came back. Since the dealer just replaced the engine for me, I took it back to them to have it checked. P2885 is for Boost Plausibility.

Here is what they documented on the repair paperwork. Test plan advised checking vacuum lines to wastegate/boost actuator. Found line to wastegate was soft and collapsed/restricted. Removed and replaced lines from wastegate and vacuum pump control valve and vacuum resivior under intake manifold.

So, there was a soft spot in one of the vacuum hoses that was collapsing on itself under vacuum. With the new vacuum lines installed, no more code and the car is running great!


Now i hope this will cure my issue

Glad to hear it's something relatively straightforward too. Smile

I once heard of something similar happening on a tuned Audi TT engine once. The standard intake hose could not cope with the pressure and kept collapsing when under load. They had to fit an uprated hose to deal with the larger vacuum pressure going through it. Smile

Well i am hoping this is what it is, the turbo has been inspected and is fine, unless boost is leeking from another area the likely cause is what i found out, but SVG will do a though examination First.

As for uprated have begun to look into it but these are a set patern form the factory by the look of the diagram i saw so it may be a No, if though its a heat problem i may get some heat wrap for this pipe work to protect it.

Sorry Joe car not fixed we are hoping this is the problem there are various reasons why i am not producing boost, but have to say SVG do no there stuff and i am confident that they will repair it.

Keep us posted Paul. As the turbo is fine it must be a minor problem albeit with a major effect.
