The car has recently come back from the shop after a transmission repair and an exhaust manifold gasket replacement. Unfortunately the engine had to come out to get the manifold off.

The car is running ok, but every now and then it goes into limp mode with the codes P065E and P2071. Both are related to the intake manifold tuning valve. It resets ok after a switch off and on, but comes on again at random moments and goes into limp mode.

Looking at the engine I have a spaghetti matrix of various vacuum lines, most of which are broken or ready to break. They are extremely brittle and the slightest disturbance breaks them. I would like to replace all the vacuum lines as I suspect this may be the cause of the this manifold tuning vale as I understand it is vacuum driven.

Please could someone furnish me with a vacuum tubing schematic?

Many thanks.

As an edit, my profile says I'm in Kent. Well that's where I'm from, I'm actually in the Dominican Republic where cars suffer from tropical climate faults such as brittle plastics and bad mechanics!

On the back of the cam covers/inlet manifold, there are vacuum actuators that move flaps integral to the cover. Have a look to see it the hose has broken or come off, same both sides and a pig to get at. Some pictures for guidance in this thread.. https://www.fullfatrr.com/forum/post431827.html 2007 TDV8 VSE
