D4 3.0 twin turbo fix

[catch-22]

As far as I can gather, the early models had issues with turbo oil drain pipes. This can happen even if the scheduled maintenance has been strictly followed. If out of warranty, it's expensive to repair and can lead to catastrophic problems.

Was there a point in time when this was fixed from factory?

[Graeme]

The problem has nothing to do with service schedules and it doesn't lead to any expensive repairs or catastrophic problems. All that is required is for the direct drain to be fitted instead of the original drain via the scavanger pump, although it may take some driving to clean out any residual oil in the intake system. The kit costs around $200 plus fitting - it took me about 4 hours.

IIRC the direct drain was fitted to MY13 models.

Good info, thanks Graeme. Do you have a part number for the kit? And any idea on the VIN range that benefits from the change?

My 3 litre Sport is now showing signs of blue smoke under heavy right foot pull away, which i believe was a symptom of the oil drain issue on the twin turbo's. Interesting enough it only started showing itself post the Turbo actuator being replaced. I am going to drop it off to Northern Beaches Land Rover to see if they will do the work under warranty..its under Allianz extended, but i was wondering if anyone has the TSB number and whether this should be covered de facto by Land Rover as a design problem??

[Graeme]

Here's the TSB noting that it could have been superceded.
85062

I was about to embark on making a warranty claim notwithstanding that my D4 was out of warranty as an earlier attempt had been made to stop the smoke by replacing the turbo, but found it much cheaper for me to buy and fit the kit myself.

The kit cost me $163 in Aug last year although possibly at a discounted price arranged by the service manager who probably preferred that he didn't spend the time arguing on my behalf with LR and then do the job probably taking more time than LR would reimburse.

Thanks Graeme. So the TSB states it's for the TDV6. Therefore I assume it does NOT apply to the SDV6, correct? I'm still getting my head around the differences between the 2 engines...

[catch-22]

hrm, ok. I thought there was a potential fault with the 3.0 that could destroy turbos followed by the motor.

Better keep reading, huh....

It's for the 3 litre.

[winaje]

It's for the 3 litre.
Please correct me if I'm wrong, but I was of the understanding that the TDV6 and SDV6 in D4 2010 onwards vehicles are BOTH 3.0 litre engines. If this is the case, my question would still appear to be valid...

[Graeme]

I'm not sure when the SDV6 badging started but think it was with MY12 and if so then SDV6 is included, ie any 3.0 / 2 turbo engine that wasn't fitted ex factory with the direct drain for the secondary turbo.

As Graeme said.

If you have the twin turbo 3.0 then check to see which drains it has fitted.

[Graeme]

hrm, ok. I thought there was a potential fault with the 3.0 that could destroy turbos followed by the motor.

I read recently that TDV8 blocked turbo drains can cause grief. I understand that these drains can get blocked in the sump when a 2nd drain plug isn't removed during oil changes. The TDV6 secondary turbo drain doesn't get blocked, only restricted enough to keep some oil at the turbo so that a little gets sucked past the bearings into the inlet tract to cause smoke but never enough for a runaway.

Cheers Graeme, it has another 14 months to run on Allianz so either them or LR can stump up for it.. have printed the TSB and will present it and provide a demo of the blue fog if they wish

[Wirraway]

I had the smoke issue appear just out of warranty on my SDV6. Tried arguing my case with Land Rover that the problem was design related and should be a warranty fix. They wouldn't come to the party. Anyway, after being stuffed around, the dealer agreed to do the work free of labour. All good now.

[zilch]

Nothing surprises me with LR Australia, even if there is a TSB out ?:mad:

If people get issues, might be worth popping over to the rrsport.co.uk site there is a thread run by LR customer relations (corporate not OZ),

For the record my MY12 SDV6 blew too much smoke under a heavy foot since day 1 pretty much. They did the drain thingy, and after that I was happy. Yes it blew some smoke when I tromped it but not too much as far as I was concerned. I come from a 300tdi Defender so perhaps have a different smoke acceptance :angel:

Later on LR found a small oil leak and upon fitting a replacement hose noticed something inside the turbo they did not like and the second turbo was replaced. Never saw a whiff of smoke again.

Point being, the drain fix doesn't always fix.

[zilch]

confirmed by LR Northern Beaches today that its the turbo drain issue, fingers crossed it does fix it ... black sooty smoke under load exceptable on an oil burner, greyish blue not

[Parkes]

My MY12 did it also from day 1, had it sorted out at the 5000km(?) check up. Been great ever since

[catch-22]

Ahh, interesting. So the MY12's are susceptible also.......cheers for the details all.

And for the record mine is a late build MY12 (Sept 2012)

[zilch]

Happy to say the mod was undertaken by the Brookvale LR dealership and seems to have done the trick, a significant and noticeable reduction in terms of smoke, both when applying the right foot and observing the gap between mine and a vehicle behind at night.. less or nigh on no dust visible in their headlights
