I am new to VW and have been reading lots on their strengths and weakness's. In regards to the intercooler icing problem, i have a question/ theory.
I have had 5 turbo volvo's with air to air stlye intercooler's similar to the MK6 jetta. Volvo intentionally puts a small hole in the bottom of the intercooler. The hole is tiny, about the size of a small needle. so there is very little boost lost.
I found out about this tiny pin hole in the volvo's intercoolers one day when i noticed my car had developed an oil leak. It was leaking out of the pin hole. Talked to a mechanic who said my PCV system was clogged and thats why i was also getting the oil in the intercooler, and he was correct as cleaning the pcv/flametrap system stoped the oil from makeing its way to the intercooler.
Maybe Volvo designs it this way to drain moisture as well? I'm not sure.
So after reading about intercooler icing on mk6 Jetta's, I wonder if a simmilar pin hole in the bottom of the intercooler would allow the accumulated water to drain when the ice thaws.
In saying that, I have had my car for 6 weeks and havent had the splash guard off the bottom of the car to actually look at the intercooler, maybe it is set up a little different and the "pin hole" wouldn't work.
It would be hilarious if it was that simple to fix though! interested to see what you all think of this theory.
.... Posted this in a longer thread and didnt get any feedback so gave it its own thread, hope that's ok. Thanks!
