Whilst at the dealer I asked if the octavia 3 has a Intercooler,  concerned that it would develop boost pipe leaks like my fabia 1.

Tech said it is water cooled. It is near inlet manifold at front middle of engine bay under the shiny metal and black plastic cover, as he showed me on show room vrs octavia.

Does anyone know whether this is a serviceable item? Ie making sure there is enough fluid in Intercooler?

I didn't get chance to press him as I had child towing me to nearest exit...

I doubt it would be engine coolant as are intercoolant temperatures kept as low as possible? Cold air = denser air?

Yeah I was aware the 1.4 TSI engine has this type of intercooler, wondered about the 2.0 TSI. Won't be engine coolant, will be a separate circuit with its own radiator. What's wrong with a traditional intercooler?! 

Present on 2l 150bhp diesel and the vrs diesel. Both Octy.

 

Just spent £270 on new boost pipes for fabia. Don't get me started lol!

Depending on the positioning you can get away with shorter boost pipes but apart from that it seems a much more complicated, more expensive and heavier solution

Im thinking water cooled with 95 degree weg?. I thought the idea was to cool the charge air as cool as possible.

 

I guess it makes the packaging easier though as you can have the intercooler ant where within reason.

AFAIK its a separate cooling loop so you still need a radiator at the front of the car and a separate pump and resovoir.

I would never have believed it, a seperate cooling loop. Wow it must be more efficient going to all that trouble. I guess it gives a little more control on the charge air temp then as you can control the speed of the pump. May be its emissions driven for cold starts, till the engines hot. Im only speculating however,  it has to be more exspensive and less reliable.
