So the original stud had failed and has already been replaced, wouldn't hurt to remove the cabling from the new point and check it all over.

Have you got a sunroof? Have you checked for leaking drains (wet carpets etc)? L405 SV Autobiography LWB SDV8, finished in Aston Martin China Grey by ETO division.

Any help thanks

Turbo boost pressure sensor more or less vertically above it, it's tucked away under the manifold from what I remember. If you can find it, follow the wiring local to that area as there is a connector going to it. It's made of quite brittle plastic and the hose can snap off. Have a look in the end of the hose to see if it snapped. L405 SV Autobiography LWB SDV8, finished in Aston Martin China Grey by ETO division.

Just look at the hose and it'll be above the end, it's tucked away admittedly. L405 SV Autobiography LWB SDV8, finished in Aston Martin China Grey by ETO division.

Does this cause engine to shut down thanks

It monitors secondary turbo boost pressure so it's definitely not going to run correctly without the sensor connected. Did you find it? L405 SV Autobiography LWB SDV8, finished in Aston Martin China Grey by ETO division.

Can't find it
Thanks

Was that last picture you posted when the engine was out of the car or is it not of your engine?

You'll probably need to remove the 2 hard plastic fuel lines from the left side of the fuel cooler that run alongside the right hand cylinder head and the ace fluid reservoir and maybe the airbox to get close to it as its tucked under the cylinder head. It's mounted with the pipe nozzle facing down and the cable connected to it clips to the cylinder head just behind where the vacuum solenoids are fitted. L405 SV Autobiography LWB SDV8, finished in Aston Martin China Grey by ETO division.

If the charge air pressure sensor (the one you are looking for) is not connected the engine will not detect secondary boost pressure and the engine will operate in mono turbo mode and set a reduced performance error.

You have a DTC P010C-00 that references back to this, so it's definitely your problem. It wasn't in your first scan though, did something happen in between scans relating to this area of the engine?

If the engine was removed and the secondary turbo outlet pipe was left dangling without any support it's highly likely that the nipple will have snappped of the sensor. Maybe it would be a good idea to give us a bit of background to the story??

Just checked the WSM and you need to remove the AC pump to gain access to the sensor, see pics

Hi connected the Turbo boost pressure sensor
Now rev doesn't go over 1000 and shut off
Thanks
Engine was removed and rebuilt

Any body thanks

I think it would be useful to all if you gave us a bit of background to the car rather than one liners all the time. Secondary turbo charge air sensor hoses don't just fall off... L405 SV Autobiography LWB SDV8, finished in Aston Martin China Grey by ETO division.
