In the manual at page 88 it says:

"Caution

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."

Who are doing this? I have newer before used to have my old car running at idle..

Key part of that is if operted at periods of high load. So if you've been ragging it give it a cool down. If its normal low speed driving dont.

Phu.. Good thougt I had done sometihing wrong

total agrement, if you have been giving it some, just a small time at low speeds just to let it cool down, ive done this on all my quick cars.

Done it just now

iam just let it idle with air condition on for a bit while smoking outside , usualy untill 98°oil or below .

or drive smooth the last bit .

This is something that most manufacturers recommend with turbocharged cars, due to the turbo rotation speed and the sudden lack of oil feed when turning off - turning off while the turbo is still spinning can cause instant oil starvation and premature bearing failure!

well the turbo got an additional pump going wich runs for max 15mins after turning the engine off , but still let it idle a bit just for the peace of my mind

Agreed and heard of this before.

Probably good practice to do this but don't think its necessary. Like others have said there is an auxilary oil pump which continues to circulate oil round the turbo to prevent this sort of damage. Technology has come on leaps and bounds from the Subaru Impreza/Sierra Cosworth days!

From what I have gathered it is always good especially after heavy usage to let the engine run idle no matter how much the tech has evolved.

It is not an accident that the manual has info regarding this procedure. A couple of friends have installed a turbo timer for this just to avoid the hassle of staying in the car.

It's not just the turbo that benefits from a short idle after a high speed or heavy load journey, new technology acknowledged. Pistons and valves do too. Oil can carbonise behind and around the very hot piston rings leading to blocked oil ways in the pistons. This is more likely in a turbo'ed petrol car due to the increased combustion pressures. But the main problem for the turbo is that it gets horrendously hot in a petrol car, near to red hot in fact if you rag it! The oil in the bearings just fry's and carbonises if the engine suddenly stops, although obviously the new tech is a help here. But, over time this causes problems if the correct technique isn't adopted. It further reduces oil flow to the bearings and increases the heat the bearings experience causing premature failure. It is less of a problem now than it was but it's best to follow the instructions in the book. Turbo's are somewhat expensive, so is the rest of the engine if the turbo fails prematurely taking the rest of the engine with it. Looked after, your turbo with last for ages without any problems. Enjoy!

I'm confused. I've heard the extra water pump running (and popping noises from the top-up bottle) but didn't know about an extra oil pump?

After 55 mins on a recent constantly fast (but not excessively fast)journey, I needed fuel and at 131.9, pulled in quickly and just switched off so as to refuel and be on my way. Was this wrong?

Nah, you'll be fine - I think its more likely aimed at fast A/B road stuff then turning off.
