Driving a Diesel- Things to remember

[Indian]

"you should not switch the engine off right away at the end of your journey after
the engine has been operated for a lengthy period at high loads but should be allowed
it to run at idling speed for about 2 minutes. This prevents any accumulation
of heat when the engine is switched off"

It does say after lengthy drive on high loads. This does not apply to us immortals who use a car to move from A to B. Long term damage, some might say but my 15 year old car has passed the 305,000 km marks and the engine still has not been opened and still on the original factory turbo.
My instruction manual too say that after long drives with heavy loads, idle a few minutes before switching off but how often do we drive like that? On my trip to Romania a year ago I drove about 3000 km in 36 hours and there was no need to idle every time I stopped to fill up or take short rests.
When I turn off at the exit from the motorway, my engine speed is low and the few hundred meters of rolling into the gas station gives ample time for the turbo to stop and cool down.

IMHO, we do not have any definitive answer on "what constitutes a lengthy period at high loads" unless skoda( or other) engineers publish something. But then they are known to lie even on their emission test results ..

Dont worry, toll booths after every 70 km or so take away all the heat your car generated!

Here I want add my view.
Say You have done a long journey 400 kms and arriving home.
Now we reside in a city and not on highways. And speed of car comes there to 30-40. Then some turns in the lanes, speed 20-25. All this has taken about 20-30 minutes.
Your car has grabbed enough breath. Isn't it?
Now you are entering the parking place and 2-3 minutes more gone.
If you are living in your individual house, you will first open the entrance gate, take your car in to the parking place. 2-3 minutes gone.

Perhaps I have made my point clear.

And your point is?

Magnan what about the 400 KM's at high speed? This is what is being discussed.
If you drive 200 km at high speed and park your car on the service lane and immediately shut the engine, the turbo may get damaged.
Buy thankfully, the Government of India has solved this issue by their innovative and technologically advanced thinking. They timed and carefully placed heat absorbers after every 70 KM's such that your car's engine doesn't turn off for 3 minutes and doesn't suffer this ordeal. They call this innovation as Toll Gates.
To top that, if the heat absorber take more than 3 minutes, you don't have to pay for it's service!

Unless and untill Oil is doing its job, its unlikely to damage the turbo or engine after long drives too, whatever be the load.
i never saw my average speed going upto 96 or 98Kmph, on my weekends 825Kms drive on NH-4.

i follow only, morning idling for hardly 30 secs.

[Magnan]

And your point is?

My point was that by the time you are ready to get down from your car and enter the home, it has taken enough breath for switching off the engine.

It appears that you don't agree.

Fine.

I just found out that my car has an electric water pump that circulates the coolant for a few seconds after I switch off the engine. The pump stops after the coolant reaches a certain temperature. This pump is connected to the coolant sensor on the engine block.
I noticed this pump running when I returned from Finland and noticed a humming sound when I switched off the engine.

now days all modern cars have these things.
