Ok, just using it almost as a daily tbf so won't be staging it and done 155k tbf...

Well, was about to come and say all running well since had car back this morning, and before had the pcv,plugs and coil it looked more like it was minus 10 outside with the exhaust/steam out the exhaust but now there's none of that and a tiny bit from the exhaust that u can see so thought, nice sorted.

But the "blowing noise is still there on decel" and as it was at idle nothing wrong in the revs , nice and settled, but u get a little putt, few seconds later putt...

And the ecl light flashed up 🙄🙄...

That’s exactly what I’ve done and had no issues,

Did this too. No issues either.

I could be wrong but I understand that the silica bag was put in place to stop the degradation of the G13 cooling and corrosion resistance over time? I took mine out a few years ago and now just drain the expansion tank and replace with fresh G13 every year and then test with a floating disk tester. The stuff in the link above seems a better choice though.

Thanks, that is the only likely culprit left, so will probably end if changing it.

Having a similar issue with my GTI whereby the passenger side vents can blow out nice hot air but all those on driver’s side won’t get any more than tepid.

Tried doing the A/C reset trick but that didn’t make any difference.

Took it to dealership who said that heater matrix needs replacing but that wouldn’t be covered by the All-In extended warranty; unlike the thermostat housing which got replaced a few years ago when there was a coolant leak and they removed the dreaded silica bag.

Yes bud, ill see if the blow sound is still there on decel id imagine it is tbf...then maybe look into DV..

If did do that oem for same or a different dv? I mean its not like it tissssh when changes gear atm, dsg
