and be careful about the fuels. CRDI's are pretty sensitive to bad fuels and employ elaborate filtering systems. But still, you dont want to take any chances

PS: turbojet diesel has been reported to cause a lot of smoke with most diesels. I've switched to regular Diesel. I believe Team Bhp recommends regular fuel anyway

@ phamilyman. there are threads on that all over team bhp . here's some

Is this applicable for VGT turbos as well?

Too low rpm's, turbo lag or below turbo threshold.

Turbo and 1 minute idling. Recommended for all turbo-charged cars.

Thanks guys. I was vaguely aware of the same. It now makes sense. But I wonder why they didn't solve it with an improved turbo oil, than a timer?

My question is rephrased.
a. How can one find out if oil coking is occuring without much headache? ie idling not done properly.
b. Should one notice *some* damage, how much should one mark down a used car price by, to cover oneself appropriately?

Cheers

It is a matter of getting used to the turbo lag at low rpms, which will take you some time if you have driven only petrol cars. Hence the low end pick-up may seem less and the car sluggish.

No, that is not there in CRDis.

The best way to gauge a turbo's health is by tearing it down and having it inspected. Not practical though, no seller is gonna let you do this to his car!

The Scorpio's M2DI engine doesnt need idling. Earlier Boleros with same engine had stickers asking the driver to idle for a minute before starting moving or before switching of the engine.

Very true. This is one big difference between petrol engines & CRDi. The torque is amazing.

I was driving my friend's Swift VDi and his music system concked out. That's when I realized that the engine is not silent at all. It's just that you cannot hear them inside the cabin(with the windows rolled up and music on). They still clatter.

This depends on the Powerband of the car and the rpm at which the turbo kicks in. Flooring will not work as well as shifting down and bringing it into the power band. And flooring in 5th gear(on low rpm) on a diesel is no fun!

But I would like to know what is the lifespan of a turbo?? When my indigo was new I used to feel the turbo kick in. But over the years that feeling reduced and now(after 5yrs) I feel there is no turbo at all...

Simple don't stay long in low RPMs always be in one gear lower than what is recommended by the manufacturer for the speed you are going.

Maintain your gear-speed ratio's, and you will not have that problem. Basically means that when you slow down for that speed-breaker, the speed you are at is more suitable for a 1st gear, than the 2nd.

DF, actually people are normally in one gear higher than what the manufacturer recommends. If you notice, say at a speedbreaker, a person is typically in 2nd. But for the speed at which he is, the manufacturer would have recommended 1st gear.
