Its a proper **** to change the coolant flange. I tried yesterday, got as far as removing the PCV valve and could not get any further, due to a silver cylinder above the flange that completely blocks hand / spanner / anything from reaching the 2 10mm bolts that hold the flange on, I think its going to have to be a garage job Anyone know what that silver thing is? tried searching vagcat but to no avail. Dont want to pull it off unless I know what it does and what is likely to come out if its removed! I also found when dismantling bits that the PCV tubes are thick with semi dry oily sludge ****, and that all 4 fuel injectors are showing signs of leakage, probably from the sealing o rings but could be the upper connections from the rail. Proper pissed off now, cos if I cant do it on the driveway then i'll have to nurse it along for another month until I can afford to pay the garage to do it.
