Here's a question for you all out there. Does anyone let there engine idie to let there turbo cool down? And if so, why?

Personally I only of it if I've booted it or been on the motorway for a bit. If I come off the motorway to traffic lights I'll turn the start stop off too stop it cutting out the engine. Not sure if it's designed to account for turbo cooldown, you see. To be honest, I'm probably being over cautious but rather safe than sorry!

Anyway, will be interesting to here all your opinions. (Sorry if this has already been discussed before).

You don't need to worry about cool down, it's a light pressure turbo so is not spinning at high pressure.

Plus, you don't need to turn the start/stop off either, it's not what the system was designed to do.

I keep my cars for a long time, so have more reason to try to look after the car long term.

Before buying my Skoda Fabia III, I had a Turbo car from new for 13 years with no turbo problems at all.

My rule of thumb is when you arrive somewhere to always back the car in to the parking space.

This will give the car time to cool down before you turn the engine off, and it is easier when you go.

On the Fabia you can also look at the engine oil temperature on the maxi dot display.

I like to see 100 C or lower, but I am paraniod.

I'm encouraged to hear that you got 13 years out of a turbo'd car with no problems!  My last car was moved on at just over 13 years as was my wife's last car, so I'm in the same boat as you - my current car has a supercharger and wife's car has a turbo!

No need to worry and overthink here. On 2016 Ibiza 1.8TSI for example you can hear clearly that something keeps spinning under the bonnet when you take the key and leave the car, surely it's for turbo to cool down.

If a Skoda dealer or car's user manual doesn't say anything about the need to idle it after some spirited driving then don't bother with it.

It's alright, I'm not worried about it, just wanted people's opinions. The manual says leave it running for a minute after prolonged motorway use or something like that, but can't find it know, lol!

I work in the car trade and see cars weekly with turbo problems.

When the engine stops the oil pressure drops and the bearings in the turbo 'can' suffer long term from spinning with no fresh oil being supplied.

Some cars are worse than others but manufactures are getting better at dealing with this.

It is a long term problem for the car, if you only keep the car 3-5 years from new you might not have the problem.

Regular fresh good quality oil will always help as well.

 

But as I said I am paraniod.

As mentioned, it was more to do with high performance motors originally. All you need to do is let it idle for about 15 seconds or so (if you want to of course) just to give the oil pressure enough time to drop. The turbo won't be spinning at idle anyway (at least not quickly), problems usually arise when you turn the engine off suddenly leading to a sudden pressure drop, although in my mind, if the engine is turning, so is the oil pump.

I'm presuming that parking the car will give it enough time to slow down, given the very low power requirements when reversing into a space?

Parking it up should be fine, just needs to idle for about 10 seconds (longer if coming off the motorway or after a hard run-extend to 30secs) I usually park up, hand brake, seat belt off, then engine off.

bit like the old diesels that needed 20-30 second for the glow plugs,

 

get in turn the ignition on to kick off the glow plugs, then sort out seat belt etc and the plug light had gone out and your were ready to go with no waiting

I use that time for the radio to boot up and start talking to my phone!
