Off topic a little, but did you notice any driveability improvements after the turbo was replaced? The 2nd turbo on my D4 now seamlessly comes online and goes offline which is in distinct contrast to its previous behaviour, perhaps now coming online well below the original 2500 rpm. The 1-way valve in the inlet tract was replaced at the same time, as was the air box because it was oil-soaked.
Can't say I did Graeme. I'll let you if there's any change when I get the car back after this second turbo change:)
Well, got the car back yesterday after its second turbo replacement. The service manager said he'd taken it for a test drive and all was fine. But when I drove it and hit it reasonably hard there was still a puff of blue smoke out the back, although nowhere near the size of the traffic-obscuring cloud previously.
Still a concern though. I would have thought there shouldn't be ANY blue smoke, but perhaps it's some residual oil being burnt out. Time will tell I suppose.
Despite the problems, still the best car ever.
Hmmmm. Update #48-ish in this long-running saga.
The car went back to the dealer today (again) for what was to be a one-day exercise to replace a couple of small parts that weren't replaced when they should have been during the last (secondary) turbo replacement.
Just had a call from the dealer service manager. Lovely chap, apologized profusely, but they're going to need the car for the rest of the week as they now have to take the whole body off to get at these parts.
This sure is turning into a Peyton Place. It's now stretched over four months. I wonder how many other LR4/RRS owners are having to go through this?
Hi,
It looks like we have exactly the same issues, secondary turbo was replaced the last week but white smoke is still blowing out after hard acceleration.When went back to the dealer they said that it's going to take a couple of days for system to clear.
Any luck with solving the problem on your car?
Proud owner of RRS tdv6.:confused::confused:
Failure of drain system to crank case for turbo oil? Heard that his part can fail leaving oil pooled which gets burnt in the exhaust.
If you look at this thread, there's your answer....

That's the one ; scavenger pump. :angel:
Knew I had read it somewhere.
Celtoid mentioned my problem last year ( I haven't been on the forum for a few months) - here was the final update on that one which was unrelated to this turbo problem:
The update. It was very overfilled with oil during the service, not detected because the oil level sensor was unservicable (or disconnected? pending replacement next week). At some stage it decided to suck up the excess through a breather hose into the inlet and the rest is history - TDV6 says "I have compression and I have oil, I'm goin' for it"!
They are cleaning out the inlet tracts (and turbos? depending on where the breather enters, but I would expect that this was on the LP side upstream of the turbo).
Now "the discussion" with LR begins re the follow on effects on the rest of the system..........
the progression:
:):o:(:angry::twisted: which I hope turns to:)
For Info it has turned to :) with no other problems (well, other than the rear diff trying to fallout....), the car is two years old this week.
But mine has been blowing smoke as per this thread since new and I thought it was normal......... "Dear Dealer, can I book my car in...."
Well, I wish the replacement scavenger pump was the end of this problem for me. But sadly, no. Got the car back on Friday and it seemed all fine with a couple of sharp acceleration tests. But yesterday (Sunday) I gave it a shove to overtake and lo, there it was again, back as fierce and large as before.
Yet another trip back to the dealer tomorrow. My car is also two years old this month. Not happy Jan.
