    Angry S-type turbo solenoid

    I have been unable to locate the turbo solenoid/actuator on my 2005 2.7 diesel, despite having spent a couple of hours on this forum looking for info & using the several photos relating to how these items are repaired, particularly the soldering of a "dry" spot weld on an internal wire. I am doing this because I got a fault code P0046 (TC boost control solenoid circuit/open). Having read that it would take 15 minutes to remove this thing I removed the plastic engine cover expecting to instantly see something resembling the photos of the component. This did not happen, can anyone tell me where this thing is?

    Hoya Ray,

    This is the "Hot to use the forum" section, and may not be the best place to post your technical questions?

    Try the S-Type area (you've posted there before):

    Hi Ray.

    Did you get the Workshop Manual from http://www.jagrepair.com?

    It's very detailed with diagrams for everything.

    Here's the direct link too: http://www.jagrepair.com/images/Auto...M-Workshop.pdf

    Thanks Jim. I stumbled across it yesterday & have located the component in question. I will have a crack at removing it when the weather improves.

    Sorry- the part that I was looking at (directly underneath the large rubber pipe feeding air into the plastic box at top front of engine) is evidently some kind of sensor. I will have to do more research. The diagrams in section 303-04D of the repair manual are not very clear. Any help would be welcome.

    There are two actuators, one on each bank of the vee attached to the turbo. I wasn't aware you could remove them with the turbo in situ but then again I've never tried. I got two changed under warranty many years ago (they failed within 3 years of new) and had to pay for the third one - all on the same (driver's) side of the car. That was £4200 paid to JLR for a sub standard piece of engineering!!

    Anyway, the following pics show you where they are mounted, the actuator is Item 7, low down at the back of the engine. The second pic shows the actuator mechanical internals. I haven't got a pic of the electrics.
