I've mentioned recently that I've "treated myself" to a 2011 4.4 TDV8 Vogue to replace my fully mechanically sorted 2010 3.6 TDV8 Vogue. Perhaps not the biggest of upgrades or changes but I really wanted the 4.4, 8 speed and an ivory trim, all of which this car has. It has also only covered 88k miles and is essentially a very nice car that will in time be a fully sorted late model L322 and that's my goal. I didn't have budget for a really nice late model with a dealer warranty so I did what any Landyzone member would do and purchased a broken one. Smart eh?
Anyway, I'm working through a few issues, my main one is a boost issue for this week. I will check for leaks of course and I have taken off the donut manifold, cleaned the EGR, inspected all the rubbers etc. which all appears fine. I'm fairly sure that it's not an air leak issue as I get a couple of codes immediately:
P0046-77 (2F) Turbo/supercharger boost control solenoid - circuit range/performance - Mechanical failure - commanded position is not reachable
P0045-13 (2F) Turbo/supercharger boost control solenoid circuit/open - General electrical failure - circuit open
The first one, P0046 has been there all of the time I've owned the car (10 days roughly) but P0045 is new, last night to be exact. The logical part of my brain (not the part in control of purchasing Land Rovers) suggests that these two go hand in hand and the boost issues I am seeing are likely caused by these.
It is worth mentioning that there is evidence of rodent damage under the bonnet, some of the foam is chewed and a couple of wires to the MAF on the secondary air box have been repaired as well as a few other bits of tape and connectors can be seen around the engine bay. I will work through all of this in time to properly solder and heat shrink the wires. My concern is that there could be other damage to wiring that hasn't been found.
I need to locate the boost control solenoid and that's what I'm after the help with. I know there is a changeover valve for the secondary turbo but I believe that the primary has an electronic actuator on it too. Can any of you confirm this?
In the past I have paid for a Topix subscription and downloaded the full manual for the 3.6 and the wife's D4 but I haven't done this one yet as I've not had time or the inclination to sit for hours organising PDFs so if any of you would be kind enough to support my laziness and just tell me, I'd be most grateful.
Also, please let me have your thoughts and experiences on these engines. On the whole, I am over the moon with the car and am loving the difference between the 3.6 and 4.4 as it has far exceeded my expectations. I really hope I don't need to fit a replacement turbo. Cost aside, it's the fitting that bothers me most.
