Twin Turbo 2.7 Disco

Hi Guys, I've looked at a 2011 Discovery 4, the salesman tells me that it is a twin turbo unit but I can't find any info on these. Is there such a beast ? If so does it have worthwhile ( for the added complication) more torque & power, also fuel economy if used correctly. Are there any issues with the twin turbo re reliability. This vehicle has 105k on it with a good service history, except the auto service. I'm thinking that it should be a better tow vehicle than the 2.7 single turbo. I know the 3.0 litre is the bees knees but finances are the stinger. Thanks in advance as always useful info here.

The twin turbo is 3 litre. There is no 2.7 l twin turbo.

If it is twin turbo it will have two inlet pipes exiting the air filter on the drivers side of the engine bay. If that is the case it is a 3.0 litre.

It should be marked on the back as SDV6 or 3.0 TDV6. SDV6 replaced the 3.0 TDV6 but is the same engine.

What model is it? S, SE or HSE?

Are you sure of that bob? Mine is a 2.7L and I think it is twin turbo (think being a key word)

Bob is right, there is no 2.7 twin turbo model. The TDV6 is a single turbo 2.7, the SDV6 is a 3.0L twin (primary and secondary) turboed engine.

Best to cross check the vehicles VIN with LandRover Australia.

The 3.0l has more bottom end torque and hence more power than the 2.7. I love my SE for that fact, cant even tell its towing our van most the time, however the 2.7 is also a great tow vehicle, I doubt you'd notice the difference on the long runs.

Issues are sticking turbo actuators, air control valve (between the primary and secondary, intake hose and intercooler ducting.

No different to the single turbo 2.7 (or any modern TD vehicle)

Transmission flush at 120,000 km or earlier is recommended, especially if it has done lots of towing. Log book service is ok, but the intervals are too long, most of us are changing oil every 10,000km or 6 months, not the Log book 24,000km or 12 months.

Suspension especially front lower control arm (bushes) wear and the electronic air suspension air bags can develop leaks.

Cheers

If it has the twin intake pipes it is a twin turbo and if that is the case it is a 3.0l.

I had this argument with my son's friend who reckoned he had a twin turbo 2.7. It was a twin turbo but not a 2.7. He finally found out that it was a 3.0l but swore black and blue it was a 2.7. I think the S model if optioned with the SDV6 might not have an identifying badge, which perhaps tricks people.

The TDV6 reference that hung around for a bit is the reason for confusion I believe

To add to the possible confusion, the 2.7L was twin turbo in Jaguars but as already stated, not in Land Rovers. The 3.0L isn't a true twin turbo arrangement but the 2.7L in the Jags was, in the same way that the 3.6L TDV8 is twin turbo but the turbos on the 4.4L TDV8/SDV8 are sequential like the 3.0.

Luckily I said "primary and secondary". Agreed it's not a true "twin", but a "sequential" turbo diesel

No matter how you put it , twin =2.

Thanks guys, as usual helpful information. It is labelled on the rear boot TDV6, no 3.0 . I've looked at the photo on carpoint & it appears to have only 1 outlet at the air cleaner, same as my current 2006 Disco 3. So unless the second outlet is obscured it's only got one outlet. I got the VIN off the advertisement SALLAAA13BA588898. Looks like the salesman may not be quite up to speed.
Selling mine as I wouldn't feel right to sell it privately.
