Water cooled turbo?

[ChrisgVRS]

Hi,

Hopefully simple question! Is the VRS TSI running a water cooled turbo? If so does it require leaving engine running before switching off after a long drive? If yes how long?!

Thanks!

I don't know if the TSI runs a water cooled turbo but it is always good practice to let the engine run at low revs and load for a while before shutting down. I have always slowed down and pottered for the last few minutes before arriving at my destination and then waiting about 20 to 30 secs before shutting off. If I happen to pull into a motorway service station after bombing down the motorway at 70 mph (of course I stay legal officer) I will slow on the approach to the car park and let the car idle for a couple of minutes before shutting down. You can always do other stuff like hide your satnav and pick up your phone etc in this time. It works for me.

Yes the turbo is water cooled and yes it has an additional pump that keeps running.

I asked in the garage yesterday and was told it was not water cooled? Now I’m confused as I having read a lot was also under the impression it was water-cooled, is there any other way anyone knows of that will give me a 100% answer?

Thanks

I found this page http://www.my-gti.com/1046/differences-between-the-gti-mark-v-and-mark-vi-engine and according to borg warner their turbo has water cooled bearings see http://www.turbos.bwauto.com/products/turbochargerPassengerCarsGasoline.aspx. Not sure about a separate pump though, I suspect the cooling after the engine is turned off is driven by convection.

General driving & switching ther car off will be fine. If you have been ragging the car then a gentle couple of miles allows everything to cool & is a good idea

Does the VRS TSI not have an IHI turbo which i'm sure will be water cooled?

[ChrisgVRS]

No one seems 100% sure, I cant find any documentation to say it either way!

I'm sure Techie knows what he's talking about he is a Skoda master tech :yes:

yep, its IHI turbo in the TSI, and it is water cooled.

All our petrol turbos have been water cooled for an age, and yes they have an aux water pump, I've changed enough of them.

Would any of the derv models have a water cooled turbo?

[Tech1e]

Not ours no.

Totally off topic but I thought I would share, on a recent technical officer course I attended, one of the trainers asked how you can tell if a car was fitted with Xenons - usual answers were forthcoming, self leveling, charge up period and headlight washers.......then one of the trainees turned around and said that they were water cooled, hence the washer jet!

Sorry back on topic, yep IHI, yep water cooled, as previously mentioned.
