Hi I'm very very new to my skoda octavia rs and i want to do the best to minimise any issues that can commonly occur with turbo engines. One thing I've noticed from commenters whilst reading generally on the Web re turbo engines,  is, it recommended that when you reach home or your destination you shouldn't turn off the engine straight away but let it run for a bit to cool it down.  I've been doing this for the past week or so that I've had the vehicle, but I'm wondering, is it needed for this vehicle and at what temperature does the oil need to be for this to be effective, the highest the oil temp has gone to is about 107C. Any help would be appreciated.

If you can do the last minute or so of the run "off turbo" that should be adequate.

Running the engine after normal driving is not required unlike old school turbo engines. However, if you've been giving it a caning right before you get to your detination then it should be run for a minute after stopping.

In most conditions, say after a long out of town trip where you might have been giving it a bit of welly, the reality is that by the time you've driven through town/the suburbs to get to your house the engine has already cooled sufficiiently.

 

This is from the owners manual:

 

Risk of engine overheating!
▶ Do not switch the engine off immediately at the
end of your journey after the engine has been running
at high loads. Leave it to run at an idling speed
for about 1 minute.

Does that mean if you are out in really hot weather in the countries where you are doing really high speeds not just half max speed and you come to a halt say at busy traffic, accidents etc or motorway services you must make sure you have stop / start off?     The turbos are fine and the coolant circulates when you turn off the engine.  Running the engine is not doing much to cool a turbo or lubricate it more.   ? Why not get out and open the bonnet if you are really bothered, and get the dry ice blowing into the engine compartment.

Thanks so much for the advice,  yes 1 minute or so for when the car is being driven a bit more heavy and on longer drives. We have only done short drives though all in the city. You are correct @CS363 yes I forgot,  I read that in the manual as well.  Currently though for the first 1000 to 2000 kms I'm breaking in the engine (even though maybe not needed,  still want to do it) so I'm very light on the throttle, only rarely opening it up a bit,  but don't take it above 4000 rpm, i have only 600 kms on the clock.

I myself turn off the start stop anyway when i get in, mainly because I've read it can wear the engine quicker and also does I believe your alternator and starter in, though maybe the more newer models aren't that affected as older ones.  I didn't know that the coolant circulates when you turn off the engine,  like I said above i haven't been heavy footed on it, breaking it in. So I guess these turbo engine in the vrs are coolant cooled right or is it both. I have read that the oil is used the cool the turbo primarily. Sorry I'm pretty new at this. 

As long as you don't pull straight off the race track and stop it will be fine.

Thanks @mccririckI'll keep that in mind for the future track visits 😀

Just on this topic with the tutbo. I noticed when I turned off the engine a winding down noise,  it was muted, not very loud. Is that the turbo. To me it had the sound of the radio antenna retracting in my dads 1989 Ford Fairlane when i was growing up.

 

More likely to be the secondary coolant pump as mentioned in an earlier post. It'll be a similar, if not the same, system as mentioned here regarding a Superb:

 

 

Most later Euro cars seem to have a similar system (think Audi, BMW, Mercedes that I know of) with the usual mechanically driven water pump and then 1  or in some cases 2 auxiliary electric pumps. Some cars alsp use a secondary pump for heating/cooling when engine off or stopped in traffic.

Oh thank you so much,  I had no idea that this secondary method of cooling even existed, very interesting. Are they prone to failing, does skoda check them, maintain them, is it under warranty I wonder.
